since one of my iMacs had a temp related shutdown in W7 recently.
for fan control i use smcfancontrol with the reboot trick to keep it running when using windows
I present use and am happy with, smcFanControl and iStat on the Mac side.
I am wondering what recommendations anyone has for similiar programs while in Windows 7.
Thanks
You lose the ability to dim or brighten the display and keyboard backlighting, and I suppose trackpad functionality is also lost, but so long as a mouse is connected none of these services are essential when gaming. Lubbo's fan control works quite well, with automatic temperature regulation and monitoring. My GPU temperature rarely exceeds 75 °C when gaming (without overclocking).
I always used speedfan when I was on windows. I don't have it installed on my windows 7 desktop gaming rig though right now since I just reformatted. But I don't recall having any problems with it.
