Water Cooled GPU Overheating
Water Cooled GPU Overheating
So I just completed my first water-cooled build and began running benchmarks. My GPU instantly reached 80°C, which has happened with both of the games I've tried so far (BF1 and Fallout 4). I filled the loop as much as possible and worked to eliminate air pockets for the last few hours. I removed a few and refilled the reservoir, but the temperatures stayed the same.
Here are the details:
i5 6600k
MSI GTX 1070 Founders Edition
EVGA Z170 Stinger Motherboard
Corsair HX750 PSU
Water Cooling Parts:
XSPC Raystorm v3 CPU block
Alphacool NexXxoS GPX - Nvidia GeForce GTX 1080 M01
EK-XRES 100 SPC-60 MX PWM (incl. pump)
Thermaltake Pacific R240
XSPC EX240
4x Corsair SP120 Quiet Edition
Distilled Water with PT Nuke
(Pump/Res > GPU > Radiator > CPU > Radiator > Pump/Res)
At idle, the GPU was at 36°C and the CPU at 24-26°C. Do you think I should bleed and reseat the GPU? I followed the instructions, but that’s my best guess right now.
Can you share a photo? It might help identify any problems more clearly if we can view the setup. Also, once the temperature hits 80°C, does it quickly return to around mid-30s? What is your room temperature?

The GPU will immediately drop back to 35°C after finishing the benchmark or game.
Ambient room temperature is 19.4°C.
Is there... thermal paste on the GPU? Yes, a small amount similar to what's shown in the manual. But I recently replaced the system and took out the GPU, then reinserted it with extra thermal paste.
I just wanted to confirm there was some thermal paste applied. I've noticed folks eagerly applying waterblock, only to overlook reapplying thermal paste on the GPU die. That's me too.
Wow, you've got quite a few tight bends inside. Are you confident you have sufficient head pressure for all of that?
My intuition suggests that with this setup—especially given the in and out tubes for the GPU block beneath the chamber—the air bubbles are likely stuck inside because they always rise.
Of course, there are many times my instincts turn out to be completely wrong. Just tossing this out here.

Woah you've got a lot of really tight bends in there. Are you sure you have enough head pressure for all of that?
My gut feeling is telling me that with a loop like that, and with both the in and out tubes for the GPU block underneath the actual chamber thing, the air bubbles are all trapped in there since air bubbles always go up.
Of course, there are many times my gut instincts are horribly wrong. Just throwing that out there.
Well I thought about that too but if there wasn't enough flow then wouldn't the CPU be hurting too?
And I tipped the case many times to get any bubbles out of the GPU and I was fairly confident they were gone.
