my rig :

ryzen 5 5600x cpu
asus prime b550 plus mobo
gskill ripjaws ddr4 8gb
1070ti gpu
coolermaster liquid cooler cpu fans located on the front
two fans on top
one fan on the back

My issue currently is that I can't get the liquid cooling cpu fans from the front to work at anything less than 100% speed. It's either 100% or nothing no in between. The rest of the chassis fans follow the speed I set them at normally. At first I used ASUS AI Suite 3 for fan control and only max settings seems to get the cpu fans to work, but for anythign less than 100% I can't get it to work. I went into Bios and same issue, I set up a curve but it doesn't follow it. Any help is appreciated thanks.

Yeah, worst drivers ever:mad:
HAHA! now I'm a little worried I might've damaged my cpu since the fans weren't working for quite some time because I had recently found out about the issue, cpu temps would hit 65c-70c when gaming, but I know the AIO pump was always at 100% so maybe it's okay. Computer seems fine. Thanks again!
