Question GPU Fans run at 100% seemingly random and in random intervals on their own.

let me preface this by saying I am a newbie still when in comes to anything hardware related. So please talk to me as if i am 5 years old because i know you guys know your stuff.

I bought this PC back in Nov, 2022, A prebuild NZXT

specs:

MB: NZXT N7 Z590
CPU: Intel i7 11700KF
Video: NVIDIA GeForce RTX 3080
Case: NZXT H710

The problem started about a year and a half after i got my pre-built. The GPU fans will just act up and go 100% randomly, sometimes there is a period of weeks where it doesn't go on. Other times it is constant unless i shut down my PC. Usually it'll just go back and forth up and down throughout the day, with fan speeds mixed in with periods of time where it is completely fine.

I have MSI afterburner, GPU Tweak, and NZXT CAM (NZXT's built in monitoring software) all downloaded. all show fine GPU temps when everything is proper of 33-78 celsius. And when the fans go crazy, the GPU temps stay at 25-32 celsius. When my temps get out of control, the fans don't even kick in regularly (I.E. 80+ celsius)

I also just recently cleaned my PC out with compressed air to remove dust.

I'm worried about the health of my GPU as right now i can't afford a new one if it tanks the lifespan of it. Please if anyone has any ideas of solutions, let me know.
 
did you change the fan curve?
load default settings and set it to auto in afterburner
eventually update or uninstall afterburner and other similar tools, which altogether installed at the same time can lead to abnormal fan regulations.

update BIOS of the motherboard

check temps of the cpu as well

do all fans spin while under load?
 
thank you for the response.

I should've mentioned I typically boot up MSI afterburner and underclock my GPU, however the fans still can spin out of control when i don't. And did spin out of control before i underclocked it. I've tried messing with my fan curves before and I'm not sure if i saved them, but this also started before i even thought of messing with fan curves.

All my fans do spin under load as far as i can tell.

I believe my CPU temps are usually fine.

I will try to see if i need to update my BIOS here and get back to you.

thank you once again

a person on NZXT's comment section under a product said there have not been any new BIOS updates since i bought it. should i still try looking for the updates? and maybe they shipped with an under updates version?
