I ran a benchmark with afterburner closed and the fans sped up fine as the temp increased, as soon as i enabled afterburner and re run the benchmark the fans refused to speed up. Update, so i just put on fresh gpu drivers and it did not fix the fans, the last time the fans acted weird putting on new drivers fixed it but not this time. It happens on afterburner 4.6.2/4.6.3/evga precision.Īre 3000 series cards the problem, is something in windows 10 interfering? I did poke around in the msi dragon centre software but it had no way to change fan speeds, except for some profiles which didn't alter fan speeds, but there was an option to ramp fans to 100% which worked but no other fan control was possible, so even msi software on an msi card couldn't alter the fan speeds, somehow the card is doing what it wants instead of what it's told. Only way to make the fans normal again is to DDU remove the gpu driver, reinstall the gpu driver, then i can set the fan curve and it follows it fine, but if i disable the curve and start changing the fan speeds it completely breaks all fan control again until i reinstall the gpu driver. Nothing at all works, even if i use evga precision, its as if the gpu itself is being told from its own bios/firmware to ignore all changes to fan speed from software. Even if i go into a benchmark and make the gpu hot the fans refuse to speed up, eventually the card will thermal throttle and start reducing the core clock. I usually set a custom fan curve that makes the fans run at 30% up to 50 degrees, then as the temps rise so do the fan speeds, this works fine once i set it and leave it, but if i disable the curve and try to set a constant manual fan speed it won't apply and the fans just stay at 30%. I have used Afterburner for the last 10 years on many many cards and controlled the fan speeds perfectly fine, but this card is crazy. I have noticed my gpu fans are doing something weird.

Evga precision x fan curve not working
