    Fan Makes Noise at Startup, Then Runs Silently...

    I've had this desktop PC for 6 years. In the past couple of months one of the case fans makes a noise when I first turn on the PC. The noise lasts only until the Windows opening screen (about 45 seconds). I replaced the fan, but the new fan does exactly the same thing.

    I have never touched the BIOS so I can't imagine it has begun to cause this.

    The PC runs perfectly.

    I'm thinking it might be some sort of vibration, but I just wanted to see if anyone had any ideas.

    Thanks for any input!

    Fans can do that when they first start, often caused by dust accumulating on the blades causing the fan to be out of balance. Clean the fan carefully with a tissue.

    Put a drop of 3-1 oil on the fan central housing. You may have to pull the sticker off the center cap area to have access to the internal bearing. You can pick it up almost any where.

    Fans can be had that use either a bronze bushing type bearing, ball bearings or sealed ball bearings.

    You might want to invest in some form of solution to silence some of that vibration, like rubber washers or fan screws.
    It also not uncommon for fans to be loudest when the machine first starts up.

    Thanks, Clint (and everyone else who took the time to answer)!

    I have ordered these from Amazon: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

    I'll post again after they arrive and I install them.

    Thanks again,
