How to stop excessive fan noise on startup only

I have a laptop running Vista Home Premium. I restored it to it's factory default. Afterward I installed all Windows updates including SP3. Now when the laptop is turned on the fan spins as fast as it can making excessive noise. After boot up is complete it no longer spins fast. It did not happen before the laptop was restored to factory defaults. How do I make it stop?

Go into BIOS and set fan to quiet mode. (vice performance)

Random...
Try going into BIOS and look for a fan speed setting... That makes me curious

this just might not be the software issue - open the laptop, clear the fan from the dust maybe ?

Excessive noise?

If it's whining/screeching and then the noise disappears after a few minutes then the fan bearing is gone.  Replace the fan in this case.

They are right, just like some PCs and servers, until they get up to speed the BIOS spins the fan at max speed by default to make sure it is cool during boot.  It slows down whenl the power / temp management of the OS takes over.

I wonder why it did not do that before ?

I'm assuming when you went back to factory defaults, you didn't default the BIOS?

Because the default is not where it was set before.
