Sometimes the fans do weird things. Our laptop fan does this, and we just reboot it, and it stops.
My tower fan always comes on when usage is high...mostly graphics. When I play Angry Birds on FB....my fan comes on almost every time. In the hot summer I put an exterior fan blowing on my tower and that helps. Put your hand on the top of the tower, or under the laptop and if it is warm, then you should do things to enhance air flow.
My son says if your tower is in a cubby move it out if you don't give an external fan. If you have a laptop put some pencils under the bottom to raise it up, so air can circulate beneath it.
If it is hot, it will kill the motherboard eventually.
We don't have A/C in this house, so overheating is a huge issue for us.
