Fans not working on Geforce 3080 RTX?

[Wildnomad]

Hi there,

Just got my new PC this weekend. Had lots of issues with it. At first it wouldn't start (1 long beep proceeded by 3 short beeps). After about 4 attempts and pushing at some connectors I managed to get it working. Then I couldn't get windows to shut it down or go in to sleep mode. Think I've fixed that now as well.

Anyway, since I've had all these issues I have noticed that the fans on the Geforce 3080 RTX GPU aren't working. They spin when the PC initially starts up (so they are connected) but then don't move even when playing full screen video and scrubbing through the time line in Maya. Not sure if it's a problem or not. According to HWmonitor the GPU hasn't gone higher than 49oC. Could it be that it hasn't got hot enough to initiate the fans?

Mike.

Gpu fans don't activate until they reach a certain temperature.

Sounds like you haven't configured hardware acceleration in Maya? Doesn't sound like the GPU is being used?

My own GFX card's fans don't spin up at all until circa 50 degrees, you could get software from whoever made it, and attempt to run them manually, or just run Heaven or some other intensive benchmark to see if they work, but modern cards don't spin up until they need to.

Depends on the fan curve set for GPU. If it’s set to only start fans when GPU temp hits 50C, then fans won’t kick in while PC is idle or low GPU usage. You can try running a benchmark like Heaven or 3DMark to push the GPU and confirm fans kick in

Personally, I use MSI Afterburner to set a custom curve for GPU fans and then only start at 50C.

Thanks everyone. You've put y mind to rest

Don't settle for how it's operating now, you need to get Maya using the GPU, it's fairly straightforward, otherwise you're not utilising the full power of the machine and relying solely on the processor

Thanks Spyder. Maya says it is actually using the geforce GPU. In fact it doesn't give me the option to use the CPU strangely. Still doesn't raise the temperature above 47 degrees even on an intensive render. Just installed Unreal Engine and that got the GPU's attention for sure. Fans wurring nicely
