cpu fan error on boot up

From time to time and it is random, usually when I first start up my computer in the morning I get a cpu fan error.
Any ideas why? This computer build is only about 7 months old and I just blew out my comptuer which wasn't very dusty but it keeps giving me the error. I recently had win xp installed (now have vista x64) and when I ran TAT it said my proc temp was 25 degrees C. But it does somewhat bother me that i'm getting that bios error on start up. Any ideas why? And is there a cpu monitoring program I can run in vista x64, tat and speed fan aren't working for me.

Thanks.

It's because of your aftermarket CPU cooler. With its bigger fan, it spins slower than the stock Intel cooler, and so the BIOS sometimes thinks the fan is going bad (spinning too slowly). You'll need to go into your BIOS and find the page with settings for monitoring the CPU fan speed, and deactivate that monitoring.

Well actually when the msg did first appear the fan was actually stuck. And after I blew it out good it seemed to work ok but I still got the msg. I regularly blow out my computer every 2 months or so.
