New PC build - fans go loud during even the lightest tasks

Hi! So I finished putting together my new pc today. Everything seems to be working fine except the fans.

I have two Corsair case fans : ML120 Pro & ML140 Pro. My CPU cooler is the Noctua NH-uh12s.

So, it seems that no matter what I do in FanXpert or Q-fan(Asus Bios) the fans keep at a low RPM then suddenly go ham for a few seconds before going back to silent. This happens even if the cpu is at around 31-39c, which shouldn't warrant such aggresive behavior, right? Just lighter tasks such as opening Chrome or another program can cause this.

The case fans are the primary culprits here. I opened the case and watched as the madness began, and it seems as even though the CPU fan also spins up, the majority of the noise comes from the case fans.

CPU fan is plugged into the right place. The case fans are connected to "case_fan1" and "case_fan2.

I did at first mount one of the fans the wrong way, I fixed that but it didn't help with the problem.

If needed here are my specs: ASUS Z270 Prime-A, i7 7700k, Asus GTX 1070 Strix, Samsung 850 500gb SSD, Ballistix Tactical 2x8GB 3000mhz DDR4. Win10

 

Maybe I should include some numbers! So, when opening the Battle.net launcher this happend: Casefan1 went from ~400 to ~1400, casefan2 ~400 to ~1200, CPU fan from ~290 to ~600rpm.

Thanks:)!

look if you have the latest bios version. the bios may look at the voltage increasing a bit and thus increasing the rpm

I actually updated the BIOS before installing windows - something that I now regret. I guess that could be the reason for this, and I have a creeping suspicion that rolling back the BIOS isn't easy.

 

Anyway, "Q-fan control" in the BIOS is set to use PWM so voltage shouldn't be a problem right?

Rolling back to an older bios should be the same process as updating to a newer one.

Check your fan curve settings for each header. If you find them. Too loud, lower them.
