Solved GPU block Tags: Water Cooling GPUs Overclocking Last response: February 4, 2013 7:53 PM in Overclocking Share doraemon February 3, 2013 4:29:01 PM Hello, Does anyone know the pressure drop vs. flow rate chart for the EK-FC7970 Lightning - Acetal+Nickel? I've been searching, but I couldn't find it anywhere. I'm planning on buying the RayStorm 750 RX240 WaterCooling Kit or the RayStorm D5 RX240 WaterCooling Kit, so I needed that info to make a call. I will be adding the GPU block and another radiator (120 or 240, not sure yet) to the loop. I read that the X2O 750 Bayres/Pump (Black) V4 will be enough for most CPU + GPU loops, but I want to make sure that I will have a good flow rate (>= 1 GPM) with it. If someone with a similar set up could share the experience and ease my worries, I would appreciate it. Thanks.

Well, I kept looking and found nothing, too. That's expect, since it is a really specific GPU block. Anyway, I really appreciated your help. Thanks! Can't find your answer ? Ask !
