If you own a Thinkpad Notebook you probably aware of the cooling fan noise annoyances, if you suffer from the noise and want to have a quiet life and gain control of the fan speed take a look at the Thinkpad Fan Controller.
The Thinkpad Fan Controller allows the user to control fan activity based on the system temperature (or manual of course...)
This Visual C++ project controls the fan via port IO to the embedded controller.
p.s. though it was build for the T4x series... its working great on my T60p.
