under FC3, my laptop fan seemed to do the right thing: off or nearly off most of the time; switching to a high speed whirh after the CPU had been at max freq for a while. Since installing FC5 (and putting in a higher-capacity hard disk), the fan is contantly on at a low-ish speed regardless of CPU frequency. Any ideas where I should look? Its a Dell D400 with 1.4GHz Intel Centrino. -- Little fly, thy summer's play my thoughtless hand has terminated with extreme prejudice. (with apologies to William Blake)
