CPU paired with EKWB Predator and Poseidon GPU.
So I purchased an EKWB Predator 240 and connected it to my CPU (i7 4790k @4.80ghz). I chose the EK AIO because it’s expandable and has a nice design. Initially, I was idling at about 29°C with less than 100% load, and it was only around 45°C – that was good news. Then I thought about adding my Asus GTX 780 Posideon to the loop.
I expected the CPU temperature to rise during idle but was pleased to see my GPU running cooler. However, while the GPU stayed between 45°C and 65°C—about 10°C cooler than before—I found my CPU reaching up to 75°C, which is significantly higher than the GPU. This caused some game performance drops.
I checked if the pump was working properly or if I needed to refill the liquid. Everything seemed normal, but I noticed water flowing through the water block under a flashlight. That made me wonder if there was an issue with the thermal paste application, whether the CPU and GPU were installed incorrectly, or if I needed more radiators. It seems like adding the GPU might have been a better idea. Any advice would be greatly appreciated.
Pump might not be powerful enough for the GPU. I think the CPU should come first, then the GPU, and finally the radiator. GPUs usually run hotter during gaming than CPUs, so putting the GPU after the CPU makes sense. It’s likely the pump is the issue. If your CPU isn’t running first in the sequence, check if high temperatures change. If not, revert it back to just the CPU and see if temperatures drop. If they do, the pump might not be powerful enough or not operating at full speed. Also confirm the fans on the radiator are spinning at maximum.
