Hello guys!

I have a problem with my RTX 2060. It's one of those Windforce models, with the quiet fans (0 rpm) at idle thing.

At idle it's around 48-49 c, and when i do any task (It can be, open a browser or a game) then it hits around 50 c, and starts spinning around 1200-1300 rpm. When it goes under 50 c again the fans will stop (0 rpm).

The problem is that the fans will sound like it can't turn on/off, like it's constantly turning on and off.

Then.. When i start a game, like CSGO, the fans will go crazy and then go to 2000 rpm (Sounds like a jet engine) for a sec, and then stabilize with still a high rpm (1300) until it again hits under 50 c.

What i have tried:

  • Googled alot
  • Reinstalled the GPU
  • Reinstalled Drivers
  • Reinstalled Windows then drivers
  • Flashed latest BIOS
I also tried to make a custom fan curve like alot of people with this issue have suggested. It fixed it for now, but the problem were still there, when i used MSI afterburner and set it to 0 % up until 50 c. It would hit 50 c and do the same on/off cycle again. The only way i could make the cycle stop was to do 40 % fan speed. If i'd go lower than 40 % the cycle would start again.

My specs:

Ryzen 3600X + Cryorig H7 Quad Lumi
Asus Rog Strix B450-f gaming
RTX 2060 Windforce OC 6 gb
16 GB ram
Case - Aerocool Quartz RGB (3 intake, 1 exhaust)

Ambient temp = 25 c

Does anybody have a solution for this problem?

If you're 'idling' at ~49'C, and fans set to kick in at 50'C, the on/off is exactly as expected.

<50'C, fan is off.... as soon as temps rise that +1'C, the fan jumps to whatever RPM is set at the 50'C threshold..... if you put any major strain on the GPU, temps could feasibly jump 15'C or more, near instantly - at that point, you're essentially jumping from 49% = 0RPM to ~65% = X RPM and scaling back as the GPU cools down.

You need a more gradual fan curve from ~30'C or so. Gradual increases 30'C = 25-30% fan, 50'C/50% etc.
A fairly constant 30-60% fan speed is going to a heck of a lot less noticeable than 0% - 60% - 0% in a matter of seconds.

Well that seems to work! I will test some games etc with this.

It's just weird that Gigabyte (dunno if other brands are the same) allow 0 rpm if it's so audible and weird cycle pattern. Does this setting cost alot of power? I must say the fan on my GPU is barely audible with your settings so i guess it's not that costly, power wise.

Thank you very much for your help though! :)

0RPM is mostly marketing. Unless you spend your time with your GPU (mostly) dormant.

My 2070Super runs 0RPM while I'm doing work with my system inside Citrix, but I sit at 39'C max in those circumstances. If my ambient were higher, or I had poorer airflow, I'd likely be in the same position you are.

Configured correctly, and in the appropriate circumstances, 0RPM will keep the noise down.
However, with reasonable airflow & a normal number of fans in your case, you're unlikely to notice ~30% RPM in most instances. They can't account for all potential variables (is 49'C idle), but it sure 'sounds' good in marketing...
