(Resolved) dell laptop fan problems - Page 2

What temperature monitoring software are you using? It is probably incorrect.

The reason it is running at a reduced speed is because SpeedStep is slowing down the processor when it is not under load. As long as it is at the reduced speed, the processor is not under load and is likely cool.

i am pretty certain i now have the problem resolved as far as one fan running, intel cpu id shows 400mhz 2.0ghz and i am staying at a cool 40c in a cool basement, i would say its about 65-70f down here, but all i had to do was get my power setting for when things turn off set right and now everything seems to work fine, pcpitstop.com gave me a good score and passing flag on my cpu and ram this time around, so basically bios and windows power settings were the problem, but the issue with the exhaust fan not running is still a mystery. maybe someone will happen a long with a theory on it since in linux i get a opposite effect the fan that does not run in windows runs in linux, but the fan that does run in windows does not in linux, so close to solving it

oh and that utility shows my cpu running at 1198mhz with little or no load, so maybe it is from the adaptive power setting i have it set to, wish i bookmarked the page that helped explain speedstep.

well the other fan has been running all along lol, just never noticed, but it working and thanks guy for helping me to find the solutions.

You're welcome. That must have been a quiet fan if you didn't notice it.

actually it runs a little louder but every time i looked when i thought the fan got faster, the other must have stopped, but the odd thing is i stressed the system with americas army and a punkbuster update and the fans went off and didn't come back on at all hit 82c before i got it shut down, so i know it has a limit to how far it can go.
