30 Series Custom fan curve Headaches!

[m6tzg6r]

In the image you can see i set the fan speed to a constant 35%, i then set it to increase speed to 50% as the temps rise, i usually set my curve to something like that, currently testing my new 3060 and will fine tune curve as i see fit.

Problem is the Fan RPM is not constant with the 35% fan speed, the RPM keeps slowing and rising. I tried all the settings in Afterburner and GPU Tweak but no luck.

I had a 3070 from MSI that also was bonkers with the fans and i had to settle for the default curve. This 3060 is from Asus and i still can't control the fans properly.

I have been settings custom curves since the GTX 480 but this 30 Series keeps messing with me, what is the deal with it!?

I set up a custom fan curve with GPUTweak III for an ASUS KO RTX 3060 Ti OC card and the fans behave as expected. I previously used GPUTweak II which also worked correctly.

Have you ensured that the 0dB fan setting is disabled? I dislike the sound of the fans starting up so I have configured my custom fan curve to keep the fans moving at all times. Right now, the fans spin at 900 rpm during idle (about 33 °C) and max out around 2400 rpm (i.e., not full speed). I'm pretty sure the fans stay at 900 rpm until about 55 °C and only gradually ramp up.

Looks like i have fixed the problem. I need to set the fan speed to high 40's, currently i am set to 50% and the RPM is ~850 and not dropping off.

If i lower the fan speed to a value down in the 40 range it starts causing the RPM drops.

Think of it like a car engine, if you are idle at 700rpm the engine is fine, but if the idle is lower at say 500 then the engine can start to want to stall and drop rpms, that is basically what my gpu is doing, if i don't set the fan speed high enough the RPMs drop to 0 then come back up to ~850 then drop to 0, over and over and over.
