Question Weird loud fans for 10-20 seconds every 3- 5 minutes

[patrichpachich]

One of the fans (cant tell which one) inside of my PC spins fast and loud for 10-20 seconds every 3- 5 minutes, this happens even in an idle state. I monitored the task manager and everything looks fine, nothing suspicious. When I play a game for a while it goes away ( I can tell the normal sound of fans when I play from the weird short loud fans). I have tried restarting, and on/off the PC, all of my drivers are up to date, and there is nothing new on my PC, this issue just started happening 2 days ago

R5 5650g
Asrock b450m sl
Darkflash Darkair cooler
MSI 2060s
Kingston fury 2x8gb
Kingston NV1 500gb
WD blue 2tb
CM MWE 550
Win10

Edit: after day 3 its gone, I installed Hwmonitor in case it goes back, right now I'm still monitoring everything and for past 2 days everything has been normal. Ill update soon and if nothing happens ill close the thread

First you have to find which fan but CPU and GPU are faster to react on temperature rising even for fraction of second. Try setting different speed curves for suspected fans.

Run Hwmonitor or similar.
It will show the current, minimum and maximum fan speeds.

What might have changed since all was well 2 days ago?
A windows update perhaps?
Malware/virus?
New app?
