GPU water block buyers guide 2026 RTX 5090 and RTX 5080

Choosing the right GPU water block in 2026 is one of the most impactful upgrades you can make for an RTX 5090 or RTX 5080. With peak power draw hitting 600W on the RTX 5090 under load, stock cooling solutions leave significant performance on the table. A custom GPU water block unlocks the full potential of your card — lower temperatures, higher sustained clock speeds, and measurably better benchmark performance.

This guide covers everything you need to know about choosing the right GPU water block for your RTX 5090 or RTX 5080 in 2026, backed by independent benchmark data from KitGuru’s head-to-head comparison testing.

About the NVIDIA RTX 5090 and RTX 5080

The NVIDIA GeForce RTX 5090 is NVIDIA’s flagship Blackwell architecture GPU, featuring 32GB of GDDR7 memory, 21,760 CUDA cores, and a 575W TDP — making it the most powerful consumer graphics card ever released. Designed for 4K gaming, content creation, and AI workloads, it represents the absolute ceiling of consumer GPU performance in 2026.

The NVIDIA GeForce RTX 5080 sits just below it — 16GB GDDR7, significantly lower power draw, and a more accessible price point while still delivering flagship-tier gaming performance. For most enthusiast builders the RTX 5080 represents the better value proposition within the high-end segment.

Both cards are available in multiple board partner variants. This guide covers GPU water blocks for the two most popular custom designs — the Asus ROG Astral RTX 5090 and Asus ROG Astral RTX 5080 — as well as the NVIDIA Founders Edition reference design for RTX 5090.

Why Install a GPU Water Block on Your RTX 5090 or RTX 5080?

GPU water block buyers guide 2026 RTX 5090 and RTX 5080

Stock coolers on flagship GPUs are engineered to handle sustained loads within a thermal budget — but that budget limits how hard the GPU can push. In KitGuru’s independent testing, the Asus ROG Astral RTX 5090 running on its stock cooler averaged 51°C over ambient on the GPU core and 62°C on VRAM under a 30-minute sustained load test.

Installing a custom water block dropped those figures to 25°C on the GPU core and 35°C on VRAM — a reduction of 26°C and 27°C respectively. That thermal headroom has a direct impact on performance:

  • Higher sustained boost clocks — water-cooled GPUs maintain higher frequencies for longer under load
  • Better benchmark scores — KitGuru recorded a 462-point improvement in 3DMark Speed Way with a water block installed versus stock cooling
  • Lower average power draw — cooler operation means the GPU boosts more efficiently
  • Longer component lifespan — lower sustained temperatures reduce thermal stress on VRAM and VRM components
  • Quieter operation — radiator fans run slower and quieter than the blower-style or axial fans on stock GPU coolers

For RTX 5090 and RTX 5080 owners looking to overclock, run sustained AI or rendering workloads, or simply extract maximum value from a high-end graphics card, custom water cooling is the most effective upgrade available.

What to Look for in a GPU Water Block

Compatibility

GPU water blocks are not universal. Each block is engineered to match a specific GPU’s PCB layout — the position of the GPU die, VRAM modules, VRM components, and mounting points. A block designed for the Asus ROG Astral RTX 5090 will not fit a Founders Edition or TUF variant, even though both are RTX 5090 cards.

Always verify compatibility before purchasing. EK’s Cooling Configurator at ekwb.com allows you to select your exact GPU model and confirm which water blocks are compatible.

EK Quantum Vector³ nickel plated copper cold plate GPU water block detail

Cold Plate Material

The cold plate is the component that makes direct contact with your GPU die. Nickel-plated electrolytic copper is the standard for high-performance blocks in 2026 — copper provides superior thermal conductivity compared to aluminium alternatives, and nickel plating protects against corrosion within the loop.

Cooling Engine Design

The internal flow path of a water block determines how efficiently coolant is distributed across the cold plate surface. EK’s Open Split-Flow cooling engine distributes coolant uniformly across the cold plate with low hydraulic restriction — meaning it performs effectively even with lower-flow pump configurations and doesn’t require a high-pressure pump to achieve top performance.

Full Coverage vs Core-Only

High-performance GPU water blocks in 2026 cover the entire PCB — GPU core, VRAM, power stages, and VRM components simultaneously. Full-coverage blocks deliver significantly better thermal management than core-only designs, particularly on high-power cards where VRAM and VRM temperatures under sustained load can cause throttling.

Loop Integration

Consider how the block integrates with the rest of your loop before purchasing. EK-Matrix7 is EK’s port alignment standard that ensures consistent port positioning and spacing across compatible components. For builders using EK distribution plates or planning a multi-component EK loop, Matrix7 compliance simplifies tube routing considerably.

Terminal orientation matters too — some blocks offer optional pass-through terminals for more flexible routing in complex builds.

Included Accessories

Higher-quality blocks include accessories that simplify installation and improve performance. Look for pre-cut thermal pads, an included backplate, and captive backplate screws. EK Quantum Vector³ blocks include all three as standard.

The results confirmed the EK Quantum Vector³ Astral RTX 5090 as the top-performing block across benchmark score, sustained frequency, power efficiency, and GPU core temperature.

GPU Water Block Frequently Asked Questions

Are GPU water blocks compatible with all GPUs?

No. GPU water blocks are designed for specific GPU models and PCB layouts. Always verify compatibility using EK’s Cooling Configurator before purchasing.

Do I need a full custom loop to use a GPU water block?

Yes. GPU water blocks are custom loop components — they require a pump, reservoir, radiator, fittings, and tubing to complete the loop. They are not compatible with AIO coolers.

Does water cooling a GPU void the warranty?

Installing a GPU water block does not typically voids the GPU manufacturer’s warranty as it requires removing the stock cooler. However, we recommend you always check your GPU manufacturer’s warranty terms before proceeding.

How much does it cost to water cool a GPU?

A full custom loop including GPU water block, CPU water block, pump, reservoir, radiator, fittings, and tubing typically costs between £500 and £1,500 depending on component selection. EK offers a 10% discount on whole-loop purchases when all five product categories are added to a single order.

How difficult is it to install a GPU water block?

GPU water block installation requires removing the stock cooler, applying thermal pads to VRAM and VRM components, and mounting the block to the PCB. It is recommended for experienced builders. EK provides full installation guides and video tutorials for all Vector³ water blocks.

AIR COOLING vs LIQUID COOLING FOR GAMING PCS (2026)

/0 Comments/in , /by

If you’re planning a new gaming PC or upgrading an existing one, choosing between air coolers, AIOs, and custom loops can quickly get complicated. They all promise better temperatures, quieter operation, and improved performance.

In reality, the right choice usually comes down to your hardware, your budget, and how much you care about performance versus aesthetics. A mid-range system doesn’t need the same cooling approach as a high-end build, and spending more isn’t always necessary.

This guide compares air cooling, AIO liquid cooling, and custom liquid cooling in a practical, beginner-friendly way — helping you choose the right solution without overcomplicating your build.

Gaming PC Cooling Options Explained

Modern gaming PCs are typically cooled using air cooling, AIO liquid cooling, or custom liquid cooling. Each approach is designed for different hardware levels, budgets, and priorities — from simple, affordable builds to high-end systems focused on quiet, sustained performance.

Understanding the differences makes it much easier to choose the right solution for your setup.

Quick Answer: Which Cooling Option Is Best?

Air cooling, AIO liquid cooling, and custom liquid cooling each suit different gaming PC builds.
Air cooling works best for budget or mid-range systems, AIOs offer improved CPU temperatures with minimal setup, and custom liquid cooling delivers the quietest operation and best sustained performance for high-end hardware.

The right choice depends on your components, budget, and whether you prioritize simplicity, noise reduction, or long-term flexibility.

Air Cooling vs AIO vs Custom Liquid Cooling: Key Differences

For most US gaming PC builds, the differences between air cooling, AIOs, and custom liquid cooling show up quickly in everyday use. In typical mid-tower ATX cases — by far the most common setup in the US — airflow and fan noise usually become noticeable long before temperatures reach unsafe levels.

Air cooling is reliable and cost-effective, but gets louder as hardware power increases. AIO liquid coolers improve CPU temperatures with minimal setup, but remain CPU-only and fixed in performance. Custom liquid cooling goes further, focusing on sustained performance, lower noise, and flexibility — especially for high-end systems that spend hours under gaming load.

AIR-COOLED GAMING PC

Air Cooling: Fine for Simpler Builds

Air cooling remains a solid option for budget and mid-range gaming PCs. It’s affordable, reliable, and easy to install, making it a good fit for CPUs running at stock settings.

As power draw increases, fans tend to ramp up quickly and temperature gains flatten out. There’s also no way to address GPU noise, which is often the loudest part of a gaming PC.

For many builders, air cooling works — until it doesn’t.

AIO Liquid Cooling: Better, but Fixed

AIO liquid coolers are a common step up from air cooling. By moving heat to a radiator mounted elsewhere in the case, they usually deliver better peak CPU temperatures and a cleaner internal layout.

Installation is straightforward, and ongoing maintenance is minimal.

The trade-off is flexibility. AIOs are sealed, CPU-only systems with fixed radiator sizes and small integrated pumps. During longer gaming sessions, performance tends to level off, and there’s no upgrade path beyond full replacement.

We regularly see builders start with air cooling or an AIO, then look for alternatives once GPU noise or sustained temperatures become limiting factors.

This is typically where custom liquid cooling enters the conversation.

Gaming PC with AIO and custom water-cooled GPU by EK

Custom Liquid Cooling: Built to Scale

Custom liquid cooling removes the constraints of sealed designs. Instead of relying on a single unit, you build a loop from individual components — water blocks, a dedicated pump and reservoir, radiators, tubing, and coolant — chosen to match your hardware and goals.

The biggest advantage is how well custom loops handle sustained performance. Larger radiators dissipate heat more efficiently, higher coolant volume helps stabilize temperatures, and full-size pumps maintain consistent flow without running loudly.

In practice, custom loops shine during longer gaming sessions, where temperatures and noise remain stable instead of ramping up over time.

Custom loops also extend cooling beyond the CPU. Adding a GPU water block removes small, high-RPM fans entirely, which is why fully liquid-cooled systems are often dramatically quieter than air- or AIO-cooled builds.

Brands like EK design custom cooling components specifically for sustained gaming loads, not just short benchmark runs.

Custom liquid cooling removes the constraints of sealed designs. Instead of relying on a single unit, you build a loop from individual components — water blocks, a dedicated pump and reservoir, radiators, tubing, and coolant. (If you’re new to the concept, our beginner guide explains what custom liquid cooling is and how it works.)

Not as Complicated as It Sounds

Custom liquid cooling has a reputation for being difficult, but modern components make it far more approachable than many first-time builders expect.

Soft tubing installs very similarly to an AIO, and starting with a simple CPU-only loop keeps complexity low.

Just as importantly, custom loops are modular. Pumps, radiators, and fittings can be reused as hardware changes, making a custom loop a long-term system rather than a disposable upgrade.

Is Custom Liquid Cooling Right for You?

Custom liquid cooling starts to make sense if:

  • You’re running high-end CPU or GPU hardware

  • Your PC is louder than you’d like during gaming

  • You care about clean aesthetics and customization

  • You want a cooling setup that can grow with future upgrades

If none of these apply, air cooling or an AIO may still be the right choice — and that’s perfectly fine.

FAQ: Gaming PC Cooling in 2026

Is air cooling enough for gaming PCs?

Yes. Air cooling is sufficient for many gaming PCs, especially mid-range systems running at stock settings. It’s reliable and affordable, but can become noisy or less effective with higher-end hardware.

Is an AIO better than air cooling?

An AIO typically offers better peak CPU temperatures and a cleaner internal layout than air cooling. However, AIOs are still limited to CPU cooling and have fixed performance ceilings.

Is custom liquid cooling worth it for gaming?

Custom liquid cooling is worth it for gamers using high-end CPUs or GPUs, or for anyone who wants quieter operation and consistent performance during long gaming sessions.

Is custom liquid cooling hard for beginners?

Not necessarily. Starting with a CPU-only loop using soft tubing installs similarly to an AIO and can be expanded later as confidence grows.

Can you upgrade from an AIO to custom liquid cooling?

Yes. Many builders start with an AIO and later move to custom liquid cooling when upgrading hardware or looking for quieter operation. Core components can often be reused.

Want a Simple Starting Point?

If you’re curious about custom liquid cooling but want to keep things simple, a CPU-only loop is the easiest place to start. It installs much like an AIO, keeps costs under control, and leaves plenty of room to upgrade later.

Our $500 beginner custom liquid cooling guide shows exactly how to build a first loop using reliable EK components — step by step, without overcomplicating things.

Final Thoughts

Air cooling and AIOs both have a place in modern gaming PCs, especially for simpler builds. But as hardware power continues to rise, custom liquid cooling offers a level of control that sealed solutions can’t match.

You don’t need to start big. A basic CPU-only custom loop is often the easiest way to experience quieter gaming, stable performance, and a system that’s ready to evolve when you are.

What Is Custom Liquid Cooling for Gaming PCs? A Beginner’s Guide

/0 Comments/in , /by

Custom liquid cooling looks intimidating but for many gaming PC builders, it’s actually one of the most satisfying upgrades you can make. It’s quieter than air cooling, keeps high-end hardware running cooler, and transforms your PC into a true centerpiece of your setup.

At its core, custom liquid cooling is simply a way of keeping your gaming PC cool by using liquid instead of large air coolers and fans. Unlike all-in-one (AIO) liquid coolers, which come pre-assembled, a custom loop lets you choose and connect each part yourself. While that might sound complicated, it’s much easier than most people expect — and this guide walks you through the basics step by step.

Ready to skip straight to the parts list? If you want the simplest, beginner-friendly way to get started, we’ve put together a complete first custom loop kit you can build for under $500, using EK components and soft tubing.

Custom liquid-cooled gaming PC with soft tubing and a full CPU and GPU loop

Quick Start: What You Need for a First Custom Loop

Don’t worry — this guide explains each part in detail below.

How Does Custom Liquid Cooling Work?

Just like an AIO, a custom-loop is made up of three main components.

CPU & GPU Water Blocks

A CPU Water Block installed in a Gaming PC

Water blocks keep your CPU and GPU cool by running liquid coolant directly over the areas that generate heat. CPU blocks are easily installed, with mounting systems almost identical to AIO, making installation straightforward even for first-time users.

Pump & Reservouir Combo Unit

This may sound complicated, but it’s just an acrylic reservoir that holds your coolant, combined with a pump that moves the liquid around the loop. In an AIO, the pump is built into the CPU block. In a custom loop, using a larger pump and more coolant helps deliver lower temperatures and quieter operation.

Radiator

The radiator is how your custom loop removes heat from your gaming PC. Fans push cool air through the radiator, pulling heat out of the coolant and exhausting warm air from the case. The more radiator space you have, the cooler your CPU and GPU can run.

Why Do Gamers Choose Custom Liquid Cooling?

Gamers choose custom liquid cooling when they want more control over performance, noise, and appearance.

  • Lower temperatures for high-end CPUs and GPUs can mean more consistent performance and longer component lifespan
  • Less background noise, thanks to fewer fans running at lower speeds
  • Quieter GPUs, as small GPU fans are often the loudest part of a system and are eliminated with a GPU water block
  • Premium aesthetics, with clean tubing runs and customizable coolant and lighting

Is Custom Liquid Cooling Safe for Beginners?

Build this CPU custom-loop for under $500.

If you’re new to liquid cooling, it’s normal to feel unsure at first — but a custom loop can be as simple or as visually striking as you want. The easiest way to get started is with soft tubing, which installs very similarly to an AIO.

Soft tube compression fittings may sound complicated, but they’re actually very simple. Think garden hose: push to connect, then screw it tight.

Here’s how it works:

  1. Screw the fitting into your CPU block, GPU block, or radiator
  2. Unscrew the collar (this tightens the tube later)
  3. Slide the collar onto the soft tube
  4. Push the soft tube onto the fitting until it’s fully seated
  5. Tighten the collar by hand — no tools required

That’s it. Once you get over the fear of connecting the fittings, everything else becomes much easier. Hard tubing can come later — one of the biggest advantages of a custom loop is that it’s fully upgradeable. Start simple and improve it over time.

Don’t worry — you don’t need everything at once. This section covers the simplest, most beginner-friendly starting point, and you can always upgrade or expand your loop later.

When building your first custom loop, it’s best to keep things simple. A basic CPU-only custom loop can be built for under $500, making it a realistic starting point for most gaming PC builds.

If you’d rather start with a pre-selected, beginner-friendly configuration, you can also check out our recommended custom loop kit under $500, which includes everything you need to get started.

CPU Water Block 

Whether you’re using Intel or AMD, a CPU water block is essential. A CPU water block like the EK-Quantum Velocity³ supports current platforms and keeps installation straightforward for beginners.

Radiator 

Just like AIOs, custom loops use standard radiator sizes such as 120 mm, 240 mm, and 360 mm. Most ATX cases support a 360 mm radiator, which is an excellent choice for a first custom loop.

The EK-Quantum Surface P360M is a great all-rounder thanks to its performance and broad compatibility, making it an ideal choice for beginners.

Pump & Reservoir Combo Unit

As covered earlier, the pump & reservoir combo unit holds coolant and keeps it circulating through your custom loop.

For a first build, the EK-Quantum Kinetic³ FLT D5 is a great choice. It can be mounted to a 120 mm fan position or directly to a radiator, making it compatible with most ATX cases. The D5 pump also provides plenty of headroom for future upgrades.

Soft-Tubing &  EK Torque STC Fittings (Soft Tube Compression) 

clean-custom-loop-gaming-pc-build.jpg

Once you have the main components, all that’s left is connecting everything together.

For beginners, EK-Loop Soft Tube 12/16 mm is a great all-round choice — flexible, easy to work with, and widely supported.

You’ll also need EK-Quantum Torque STC 12/16 mm compression fittings. For a simple CPU-only loop, you’ll need:

  • 2 fittings for the CPU block
  • 2 fittings for the radiator
  • 2 fittings for the pump & reservoir combo

90 Degree Rotary Fittings 

90-degree rotary fittings make soft tubing runs cleaner and easier to route, especially for first-time custom loops.

When building your first soft-tube loop, we recommend adding a few 90-degree rotary fittings. They aren’t required, but they make tube routing much cleaner.

These fittings screw into your compression fittings and allow tubing to exit components at a clean angle, with built-in rotation for an ultra-clean finish.

We recommend starting with 2 x EK-Quantum Torque Rotary 90°

Choosing Your Coolant – Customize Your Custom-Loop 

Black Clear premixed coolant flowing through a custom liquid-cooled gaming PC

EK-CryoFuel Space Black clear coolant inside a custom-loop gaming PC.

This is the fun part — and also where beginners tend to overthink things — so keeping it simple is the best approach for your first custom loop.

A clear premixed coolant is the safest option for beginners. It contains distilled water, dye, and additives to help prevent corrosion. Don’t forget a fill bottle, it makes filling and bleeding your loop much easier.

Opaque coolants like EK-CryoFuel Solid and EK-CryoFuel Mystic Fog look incredible, but they contain suspended particles and require more frequent maintenance. These are best saved for later builds.

Prep Your Custom-Loop BEFORE filling

When assembling your custom-loop, you will need to flush your radiator before filling your custom-loop with your coolant, you can either do this with distilled water – or with our EK-CryoFuel Loop Cleaner. All custom-loop radiators will need a quick flush before use just to ensure there is no hidden debris, this will ensure your blocks stay ultra-clean.

Fans  

If you’re upgrading from an existing cooling solution, you can often reuse your current 120 mm case fans. Alternatively, fans designed specifically for liquid cooling, such as EK-Quantum Phase 120 mm, offer high static pressure and low noise output, making them ideal for radiator use.

✅Checklist: Your First Custom Loop

If you’re building your first custom loop, this is all you need to get started:

  • CPU water block
  • 360 mm radiator (check case compatibility)
  • D5 pump & reservoir combo
  • 12/16 mm soft tubing
  • 6× EK-Quantum Torque STC 12/16 mm fittings
  • 2× EK-Quantum Torque Rotary 90° fittings
  • Clear premixed coolant

If your build matches this list, you’re starting in the safest, most beginner-friendly way possible.

Ready to Start Your First Custom Loop?

If you’re ready to take the next step, you can start with a simple CPU-only custom loop and expand later as your confidence grows. Custom liquid cooling doesn’t need to be complicated — start simple, enjoy the process, and upgrade when you’re ready.

FAQ: Custom Liquid Cooling for Beginners

Is custom liquid cooling better than an AIO?
Custom liquid cooling offers more flexibility, lower noise potential, and better cooling headroom than most AIOs, but it requires more planning. For beginners, starting with a CPU-only custom loop is a safe middle ground.

Is custom liquid cooling hard to maintain?
Not if you keep it simple. Using soft tubing and clear premixed coolant minimizes maintenance and makes upkeep very manageable for first-time users.

How often do I need to change coolant?
Clear premixed coolant is typically changed every 12 months. Opaque or pastel coolants may require more frequent changes.

Can I add a GPU later?
Yes. One of the biggest advantages of a custom loop is that it’s fully upgradeable. Many builders start with CPU cooling and add a GPU water block later.

Yes. This configuration uses soft tubing and a CPU-only loop, making it the safest and simplest way to start custom liquid cooling.

Do I need any additional parts or tools?

No special tools are required to build this soft-tube custom loop.

You’ll only need basic items most PC builders already have, such as a screwdriver and scissors for cutting tubing. The pump connects via standard SATA power, and radiator fans connect to motherboard fan headers.

If your motherboard has limited fan headers, a simple PWM splitter may be useful, but it isn’t required for most builds.

Can I upgrade this loop later?
Yes. This loop is fully upgradeable, allowing you to add a GPU water block, additional radiators, or switch to hard tubing later.
