Fan runs at max when screen is dimmed to save power

Question

Everytime the screen dims to save power after my laptop has been idle, the fan starts spinning really fast and the cpu temp rises to about 60 deg C. When I move the mouse to undim the screen, the fan returns back to normal.

I'm running Ubuntu 12.04 64-bit on Sony VAIO laptop

If you don't have the time/skill to debug this, simply turn off screen dimming from "Brightness and Lock" in System Settings:
