You probably wondered if reversing the “in” and “out” ports on the GPU water block will have any impact on its performance? The previous generation of EK-FC full cover GPU water blocks and the current series EK-Vector full cover GPU water blocks are both designed and engineered in such a way that they can operate efficiently regardless of the coolant flow orientation. Because of that, there is no designated “in” and “out” port on these water blocks, but one setup has slight benefits compared to the other.

RGB stands for Red-Green-Blue, the three light emitting diodes (LEDs) that exist on a single spot. By mixing those 3 colors you can get any of the 16.7million variations in the RGB spectrum.

When you hear cricket like high pitched irritating noises coming from your graphics card (GPU), less often from power regulation modules (VRM) of motherboards and power supplies (PSUs), that is coil whine. This happens in almost all electrical devices, usually at a frequency and volume that’s inaudible to humans, especially inside a case. In some cases, you can hear the pitch of the coil whine change as the GPU draws more or less power, especially often at very high framerate situations.
