GPU Fan Question.

-Hmm, I just noticed something...

I took a look at my GPU fans and they aren't on (spinning) when I'm at my desktop. (Gigabyte - GeForce RTX 2080 8 GB WINDFORCE)

-I could have sworn they should be on all the time? But then I figured maybe they only turn on once you start gaming, so I fired up Doom and played around for 5 minutes and they still don't turn on. Maybe they only turn on once the GPU reaches a certain temperature?

This videocard features what is often called a 0Db mode:

So the fans are off until they need to be on.

Ok, thanks, that's what I speculated. I guess I'll just keep an eye out and play for a lot longer and try and see why they turn on. If they haven't turned on by 30 minutes to an hour could there be a problem? (If you had to estimate on a time). I don't wanna keep playing and risk damaging the GPU if the fans don't actually work.

I wouldn't even want to estimate a time, as it more depends on the temperature. Playing a simple game with low ambient temps would mean it can take quite a bit for them to turn on.

You can keep an eye on the temps, the fans should turn on at around... 50-60C plus IMO. I think. That is what I would estimate.

Also, the GPU will not get damaged by such temps. It will throttle at over 85C nowadays, the fans should have turned on at that point already.

 

If you are worried the fans are not working at all you can simply run a benchmark/stresstest and get a grasp of when the fans do turn on.
