Why does my comp Dell Desktop rev up?

submitted on May 13, 2010 by jack69darin in "Member's Lounge", last updated on May 14, 2010 by YanBz
My Dell Desktop revs up every once in awhile! When it does, it sounds like it is pushing the fan, and makes a rev noise! Any idea

    Your PC is more than likely getting hot and has a thermal switch that turns the fan on in order to cool it off.

    It would be best to make sure your computer is in a well ventilated area; and it doesn' t hurt to open it up and give it a good cleaning about once a year, especially if you have pets.

    If you're fan is terribly dirty you can remove the dust/dirt with an air-duster, but be sure to place a pencil or other object in the fan blades to keep it from spinning when using the air-duster as it could make the fan spin too rapidly causing damage to the fan motor.

    Do you hear any HDD spinning noise too?

    How old is your computer? Most likely the fan got bad or dusty. Just need to figure out which one. I had a similar problem on my old PC and had to replace the CPU fan (which had some issue with it's bearing and was making a terrible noise when it was on).

    Also when it is going crazy open up task manager and go tot he processes tab. Check to see if any programs are running way higher the normal memory usage.

    My wife's older dell does that if she leaves Firefox open sometimes with multiple tabs. Closing Firefox stops it and the fan pretty much instantly.

    Some motherboards actaully have the ability to vary the speed of your fans as needed.

    Are you doing anything particularly intense with your computer when it occurs?

    I think Jack's computer is dead now. He hasn't been on Buxr since he posted this Twisted

      Maybe he can check back here from another computer. I think he needs a new fan, and hopefully the overheating has not damaged anything yet.

    Mr Green Thanks everyone for your comments. It is only 2 years old, but the fan was terribly dirty, and I also took the back wall off my deask to ventilate it more. It seemed to work!

      It's nice to see that it didn't totally crap out on you. Some of us were worried that we lost you due to computer failure.

    Try adding an external fan as well.
