iFanAutoControl has been working really well for me in Windows on my Macbook Pro. Unfortunately, you cannot control the fan manually in any way, but I've found it does a great job of keeping the temperature in a "safe" range. In fact, I find it BETTER in "livability" to SMC Fan Control in OSX in the sense that it slowly ramps up the speed to keep a given temperature range whereas SMC is pretty much an override "minimum" to OSX's own temperature control (i.e. if I want to be safe with a game, I have to set it to maximum fan speed since I cannot monitor the temperature while in most games, but the Windows iFanAutoControl does that for me and just ramps the fans up as it gets hotter, and lower when it cools down).
Lubbos didn't work with my Macbook Pro and InputKeyRemapper is out of date and prone to bizarre behavior with many of its settings (at least on my MBP). iFanAutoControl is the ONLY good solution I've found thus far in Windows on a Mac. Frankly, it has done a great job thus far (and I have a NVidia 8600M GT in my Macbook Pro, so to be on the safe side, I have to keep it cool to be on the safe side with the well known chip failures that seem to occur when that chip gets too hot).
