Hi, recently my all-in-one pc has developed a rather noisy cpu fan, noticeable immediately on bootup, and in idle state on the desktop when the cpu useage is barely 0-5%. When i enter the bios on bootup and check the thermal setting, the cpu fan is running at 1800rpm which i am assuming is the max speed.
I have tried changing power options from performance to power saving mode which has had no affect as well as checking the air vents for any obstructions and making sure they are clear of dust etc.
The only software changes i have made, are the hp support recommended ones such as latest windows and bios updates, among other smaller updates.
I should mention that before i made some of the big windows updates, i do not remember the fan noise being this loud before, such as when i originally purchased the pc around a month ago.
I would really appreciate any feedback or advice on this matter, if anyone else has experienced a smiliar problem to me.
Thankyou
Regards
Pete.
