Hey friends. So, I've got a question. For those of you who've seen my build, it's very compact. Now, I finally got around to benchmarking the temperatures of my build, and I came across something I find... Interesting. My CPU (which is an i7-5820K, stock clock) runs significantly cooler than my GPU (GTX 980 stock clock.) I can only think of two reasons for this. The first being, my loop order is:
Reservoir -> pump -> GTX 980 -> i7-5820K -> radiator -> reservoir
Is the liquid from the GPU causing the CPU to run warmer? From what I've heard, loops end up having an equilibrium of temperature, and I thought that positioning of (say GPU to CPU, or CPU to GPU) didn't really make a difference?
My next guess would be that warm air from the radiator is getting warmed-up, and causing a heat-soak effect. But that's odd, because the motherboard doesn't really run hot. And in this configuration, my fans are actually currently set to exhaust air. So right now, (see image below), I have just two 120mm fans, pulling air through a radiator, and nothing else in the case.
It took about an hour, and I still think there were maybe just a degree or two the build could have gained, but, after running Furmark and AIDA64 (keeping both GPU and CPU on 100% load for an hour), my temperatures ended up as the following:
CPU - ~83C
Motherboard - 52C
GPU - 66C
SSD - 37C
HDD - 36C
Lastly, if the CPU is running warmer because of the loop flow, would it be beneficial, and possible with my DDC pump, to do a series/parallel loop combination like this?
Reservoir -> pump -> (GPU and CPU in parallel) -> radiator -> reservoir
I'm also going to be testing this with the fans set to intake, although last I remember that made the build run warmer over-all.
