So, i bought an EKWB Predator 240, attached to my CPU (i7 4790k @4.80ghz), i chose the EK AIO as it is expandable, great design etc. i was idling at around 29°C and under 100% load i was barely getting 45°C - great news, then i thought well i can expand this AIO to include my Asus GTX 780 Posideon to the loop.

i was expecting a heat increase in the ave. temp on my CPU but i was happy to get my GPU running cooler. However although my GPU runs under load between 45°C to 65°C ave. 10°C cooler than before, my CPU is up to 75°C and more way above my GPU (FPS drops in some games that were fine before).

Ive looked to see if my pump had stopped or if i need to top up the liquid, all fine, i looked and could see water flowing through the water block with a flash light, so im mystified the CPU shouldnt be this hot. Is it a thermal compound application issue, do i have the CPU and GPU in the wrong order, do i need more rads? Its as though i was better off not including the GPU in the loop. Any help greatly appreciated.

Asus gtx 780 Poseidon

pump maybe not strong enough for the gpu? Cpu should be first then gpu then the rad i'd think. Your gpu is going to run consistently hotter usually if gaming than a cpu will so gpu should be after the cpu. It's probably the pump though. If your cpu isnt first in the loop make sure it is then see if the high temps swap. If not put it back to just the cpu in the loop and see if the temps drop. If so its probably the pump either not being at full speed or not strong enough. Also make sure the fans on the rad are at full speed.
