Hi, I just installed a fresh copy of Windows Vista 32bit. Been running both XP 64, Vista 64, Vista 32 before and now it was time to go legal After installation i had some minor problems with c++ runtime **** but apart from that everything seemed to be fine. I installed Test drive unlimited as i couldn't get that working with Vista 64 (That's why i got the 32b version even if i have 4G ram....). But i experienced strange behavior with the gfx driver. It stopped working etc. etc. So i fired up ATI control and noticed that the GPU where doing around 80C in temp. That's not good.. I also noticed that my fans where running at the same speed. Strange, they have never done that in Windows before.. Booted up OSX and ran SMCFanControl and noticed that the fans where running at 500RPM.. Thats normally nice but my RAM where hot as ¤¤¤%¤% must have been around 80C.. But now increase in fan RPM to cool those down. Has my SMC stopped working?? - have tried to reset it w/o any difference? Even if Windows is not able to control the fan's shouldn't that be controlled by h/w?
