<7>

THERM−to−Fan En

R/W

Setting this bit to 1, enables the fan to run full−speed when THERM is asserted low.

This allows the system to be run in performance mode. Clearing this bit to 0 disables

the fan from running full−speed whenever THERM is asserted low. This allows the

system to run in silent mode. (Power−On Default = 1).
