Hello everyone - I have an odd one here. After installing a new CPU cooler and some extra RAM my GPU keeps running at 100C and I have no idea why. (sorry if I've put the thread in the wrong place).
td;dr - GPU blows out lots of cold air whist running at 100C - have the coolers lost contact?
Details:
i5 4670K with a Radeon 6970.
Prior to fitting the cooler this was a new system using an old GPU/PSU/case and I was waiting on the CPU cooler. CPU was running @3.4Ghz (stock) with the intel cooler with the GPU slightly overclocked to 930MHz and memory at 1400Mhz. GPU was happily running at 80C in my cold room whilst gaming.
Cooler I've just installed is a NH-U9B SE2 which was performing fine as I was testing overclocking the CPU (now back to stock clocks along with the GPU for troubleshooting).
When I moved on to test some games the GPU just jumped to 100C and throttled itself down like a sad dashhund. 🙁
I have a huge old case with two massive sidefans so overall case temp isn't an issue. Previously I've never run any exhaust fans either as the air throughput is just silly.
First thought: CPU cooler fan is kicking out a hell of a lot of air so for fear of a high-pressure point I added an exhaust fan to the back of the case. I'm not sure if this helps actually but it hasn't made any difference eitherway. I also tried turning the CPU fans right down(!). Sad Labrador.
Second thought: With the CPU cooler mounted front-to-back it no longer blows air onto the top of the GPU. However I was just running this GPU in an old setup with a front-to-back cooler so that doesn't make sense. Sad poodle.
The GPU is kicking out lots of cold air whist running at 100C...have I knocked the GPU coolers off their mounts?! (I don't think it got knocked....) Sad terrier.
Any help appreciated. I've never taken a GPU apart to re-do the cooling contacts but is it my next step?
Cheers.
