Some have suggested that XP is just better at running chips at happier speeds but I (my legs) think the unit is running hotter under XP than it did under 98.
I know the fan works 'cause it runs during POST & XP load up to a certain point (not sure exactly when 'cause the screen is blank at the time) after which it doesn't come on again until I reboot.
I didn't think to run it under W98 but under WXP Speedfan 4.26 reports 58C while I'm typing this but a topped out 64C while doing a virus scan earlier.
I've seen a few sites that say some Dells laptops have this issue and that it relates to custom hardware for accessing the fan. There's even a Dell specific piece of freeware (i8kfangui220.exe) to address it.
Anybody else have this problem or know of a solution (that doesn't involve me dumping XP)?
