Case fans going nuts

[KillSwitch87]

Hi,

I had a custom loop until a few days ago when I swapped it out for a Noctua D15S - for this had to take the PC apart and unplug everything, I briefly removed the CPU as well to show a buddy what it looks like-  then had to reset CMOS because all my case fans were suddenly running at full speed after I put everything back together.

I downloaded AI suit (I think thats the name) and that worked for a while but today the fans started going nuts again. Since windows was acting up anyway I suspected that might be interfering with AI suite so did a full reinstall, no settings kept. 

 

After that was done I let Q fan control in BIOS determine optimal fan settings and this time, the fans are controlled for sure because the PC is silent. When I’m not doing anything. But as soon as I so much as open Chrome or a folder the fans, all of them, rev up for a second or two and since its constant up and down its driving me nuts. 

Any ideas what I could do about it? This never happened before. I never even needed extra software to control fans. :/

(3of the case fans are noctuas and three are scythes - the later are creating the windtunnel effect)

If the fans are revving up and down, it means your fan curve is too aggressive. Have you tried a different preset or a custom fan curve?
