I recently bought Gigabyte 2070 Super Gaming OC and when trying to set up a custom fan curve I've got some strange behaviour happening where fans won't spin properly if I try to set them to a lower constant speed.
Having fan speed set to 20% starting at 50C the fans will be turning on and back off every second. This seems to stabilize (keeps them turning) at say 33% fan speed - then if I lower the speed back down to say 22% it will keep them spinning there just fine, but a quick custom fan curve disable/enable we're back to the constant revving.
Is it Afterburner conflicting with something? I installed the last version of it when I got the card. I did not have any issues whatsoever on my previous gpu (RX 480).
Also the default Gigabyte's curve works just fine, no revving.
