EK-Vardar F2-140 Grey BB (400-1600rpm) - Dual Set is made of two 140mm PWM-controlled EK-Vardar high-static pressure computer cooling fans that are designed and built primarily for the highest-performance computer liquid cooling systems. It comes with a Y-splitter cable which enables you to connect both fans to a single motherboard fan header.
These fans were mounted as part of another product but never used and powered on. There are possible screw markings on the mounting locations.
Developed in-house and first introduced in 2014, EK-Vardar fans are a great choice for computer radiator cooling as they provide very high performance throughout the entire operating range. The two fans have different cable lengths in order to avoid having excess cabling and to make cable management easier.
The Vardar family of cooling fans carries the name of a type of cold northwesterly wind blowing from the mountains down to the valleys of Macedonia. It is a type of ravine wind, enhanced by a channeling effect while blowing down through the Moravia-Vardar gap, bringing cold conditions from the north to the Thessaloniki area of Greece. Most frequent during winter, it is blowing in the rear of a depression when atmospheric pressure over eastern Europe is higher than over the Aegean Sea.
The key characteristics of EK-Vardar fans are:
High-static pressure / low noise profile - Unlike other general-purpose computer cooling fans, the EK-Vardar family of fans is built specifically for computer liquid cooling systems, namely radiator cooling. The 7 fan blade design is optimized for high-pressure operation while maintaining the low noise profile throughout the whole operation range of the fan. Vardar's design and construction are also very suitable for high-performance air coolers or as case fans for restrictive cases with dust filters.
High-quality motor and bearing assembly - Actively cooled motor windings and the Dual-Ball bearing with 50.000 hours of lifespan (MTBF) ensures uninterrupted operation for years to come. Precise Pulse Width Modulation (PWM) for fan speed adjustment allows performance on demand.
Sealed-edge fan casing - The classic, yet effective square shape of the fan casing provides optimal performance in either pull- (suction) or push (pressure) regime without hydraulic losses thus ensuring the optimal cooling capacity of your liquid cooling radiators. The classic shape of the fan frame also allows easy cable routing while grouping more fans on one radiator.
Timeless design - The EK-Vardar EVO fan fits subtly into any liquid cooling computer without drawing too much attention. Delivered in an industrial black and grey color scheme it blends perfectly with a sleek and minimalist looking EK-CoolStream liquid cooling radiator.
