• Dust buildup in the computer prevents proper cooling, so the fans have to work harder.
• Corrupted Power Manager chip settings. Go to the Apple support page and search for "Power Manager" "reset" and your specific model.

• Shorted fan driver transistor on the logic board or in power supply (one fan always runs at max speed).
