Hello everyone, this is my first post on the forums and was wanting to ask for a little help with an issue I have. Will have my specs posted below. So set a custom fan curve in msi afterburner as id prefer the fans to be running as opposed to the cards 0rpm mode. However I'm having an issue that sometimes the cards fans will stop and start multiple times when booted into windows then eventually settle and spin normally, although a good majority of times one of the fans will stay off whilst the other two are still spinning. Turning off the custom fan curve and re-enabling it in afterburner sometimes works as a temporary fix but not always. This has got me stumped. Any help would be amazing thanks. :)

Specs:

Gigabyte RTX 3070 Vision
i7-10700k
Asus ROG Maximus XII hero
32gb 3000mhz Corsair Vengeance RGB pro
Toughpower GF1 ARGB 750w gold - TT Premium edition

get that on my aorus 2080 and thats using gigabytes own. Have you tried Aorus Engine to control the RPM of the fans ?

Seems to work but man this software, can barely change it and the curve seems to be barely customisable. Certain points are anchored to one another which makes this pretty useless unless I'm doing something wrong.
 
I think Gigabyte had an issue with this in the 20 series cards. Thing is that if unless you try to start the fan pretty aggressively it can stall. Gigabyte added something to the 20 series were the fan gave a little pulse - a kick if you like - to ensure it didn't stall if users set it at too low RPM. Thing is people complained about the pulse because you could hear it. I guess they removed it in the 30 series. But getting back to the point, why this happens, it's simply you are trying to drive the RPM too low and it's not giving the fan enough power to start rotating. What I do with mine is set the fan off until say 35 degrees C ( or whenever you want it to come on ) so have the fan curve in afterburner set to zero all the way up to 35 degrees, then at 35 degrees step it straight up to 30% ( well you can tweak that figure to what works for you ). That sudden jump to a decent level gives the fan a kick that is enough to get it rotating. To ensure it doesn't pulse every few seconds, set the hysteresis to say 4 degrees.

Hey thank you so much for the detailed reply, this seems to have fixed my issue. There is no way I would have found this out by myself. Thought I might have had a dodgy card on my hands or there was some kind of confliction somewhere. I can rest easy now haha.
 
Why do you want to fan to spin all the time. The 0rpm mode is perfectly fine. Just let the card itself to manage the ram curve.
 
One question is whether the fan will move properly from 0 RPM mode, will the BIOS need to request 30% to get moving?

For what it's worth my Gigabyte 6800XT didn't seem to have this problem.
