Describes the liquid flow distribution. In parallel connection every liquid cooling block receives only a portion of the total flow rate. Not recommended for blocks with dissimiliar pressure drop characteristics. Large parallel flow loops may result in a low partial flow rates through water blocks.
A gorgeous opaque looking coolant, based on zinc oxide which comes in many colours. Excellent cooling- and corrosion preventing characteristics to boot!
Printed circuit board with electricals interconnects which houses the electrical components, such as microchips, capacitors, resistors etc. Often referred to graphics cards and motherboards, i.e. »what PCB version is your MSI GTX 970?«.
Platform Controller Hub is a motherboard's chipset. Intel's term. Also known as SB.
Polyethylene terephthalate glycol. Plastic material, a popular choice for hard (solid) tubing, an alternative to Acrylic.
A threaded plug for closing of unused ports on the liquid cooling gear.
Polyoxymethylene. See Acetal.
The maximum pumping height of a liquid cooling pump with no flow at all, not achievable under normal circumstances. The higher the value, the more suitable is the pump for big liquid cooling loop with water blocks in serial connection.
The hydraulic pressure difference seen between the input and output of a cooling component. The higher the flow rates, the higher the pressure drop. Pressure drop is a function of restriction, which is due to differences in general construction.
Polyvinyl chloride, with addition of plasticizers a popular material for soft translucent tubing. See Plasticizer and Tubing.
Pulse-Width Modulation, modern duty cycle control allowing fans and pumps to perform on demand. Unlike voltage control PWM control actually lowers power draw.
