Hey guys
I've got a hp elitebook 840 g1 and this fan is making noise check the photo the big red circle tells which fan

I opened my laptop just like that but didn't see any dust should I remove the fan too and check more if there is dust somewhere deeper , also my laptop doesn't overheat
It is weird sometimes it makes noise non stop and sometimes every second makes noise, stops , makes noise ,stops , makes noise ,stops .... and sometimes it doesn't make noise at all I don't understand what's going on ?

You do have discrete amd graphics. Start and stop fans are often found on gpus and they are off until they hit a certain temperature. Then again it could be another fan entirely misbehaving in your system. Can you install hwmonitor and watch the fans and see which one is dong it?
