My hp p6630f desktop computer is less than a year old. Every once in a while, the CPU fan is a lot noiser than usual. If I momentarily put the computer to sleep and then awaken it, the noise is gone. The noise is also gone if I turn the computer off and then on again. What is the cause of this additional noise? Need I do anything about it?
It sounds like basic fan speed control - the computer heats up too far, the fan speeds up to cool it down, then goes back to a quieter speed when the temp has been lowered.
Has this always happened or is it a new problem? If it's recent, it may just be due to dust and dirt build up in your fan and heat sink. You can blow the dirt out with canned air and see if this makes it stay quiet more often.
I see your post and the reply from CohenTheBarbarian about cleaning out dust, etc., important to do info .. Hopefully that cures your noisey fan issues. If it does not, you mentioned "My hp p6630f desktop computer is less than a year old", please advise HP of the issues. If you need help contacting HP please let me know via this post.
