Re: Constant High GPU Temps Bad?

Hello,

If I am mining with my GPU 24/7 (R9 280x), at a pretty much constant temp of 65C, and have my fans running around 2000-2500 RPM will it decrease the lifespan of my GPU? How long till it might stop working?

Would water cooling it help my GPU "live longer" by keeping it at low temperatures?

How long has your GPU been running 24/7?

Thank you.
If you keep your GPU at 65C, it shouldn't shorten it's lifetime at all. However, it might decrease the life of the fans on the GPU. I used to run a 7850 24/7 and after a year or so one of the fans began to rattle. You might want to keep that in mind.

So the only thing that is in danger is the GPU fans correct? Do you have any tips to keep the GPU at lower temps, so the fans doesn't have to turn so fast but keep the hashrates as high? I set my Max allocated GPU to 60% should it be lower? Right now 60% or 100% gives me the same hashrates.
You could try adding additional fans to your system to lower the load on the GPU funs, then they could run at slower speeds. You should just make sure your VRM temperatures are in check too - some GPUs have sensors for the VRMs and their temperatures will show up in GPU-z. I'd try and keep VRM temps below 80C.

You could also try downvolting your card - that way it would take less power, and the fans could run slower too.
