Hi,
I have just installed Windows 7 to my M3438G but no mather what I do I can't make the fan to slow down.
I'm guessing it's because of Nvidia Go 6800 driver as there where problems with XP when using some driver versions.
I have tried 5-8 different drivers from Fujitsu-Siemens website, laptopvideo2go.com and few others including one offered by Windows 7 automatic update but none have fixed the issue.
On XP the fan problem sometimes concurred when Nvidia service in My Computer -> manage -> Services didn't start but that's not helping on Win 7.
I have also tested Notebook Hardware Control & Rightmark CPU Utility to adjust powersaving plans but no help. Using the second one I can make the fan to slow down a bit but not even close to what it does on XP which is weird. Also my BIOS is up to date.
regards
Jouni
