    Is there an app such as SMCFancontrol for windows, which will run in the background, at login, and allow me to put the fans upto to atleast 4000, and actually change as the temperature does? My MBP is getting pretty hot as im playing games, far hotter than i allow it on OS X.

    MBP is a pretty hot machine, but it should be able to handle the games with no problem... also, there isnt an air intake for the mbp so.... i dont know how well the fan actually works -- on the other hand, the MBP can handle temperatures of up to 95 degrees Celcius :eek:

    I have the same concern that you do...and really the only solution that I know of is really a pain in the ass. but it works.

    What you have to do is boot up into OS X, then open smcFancontrol (I'm assuming you already have it). You change the RPM to whatever you want, I usually just switch it to High RPM. Then you have to *RESTART* the computer and boot into Windows. By restarting the computer you have left the fans running at the speed that it was already on. So essentially, you are just turning on the fans and leaving them on. It's not a convenient way, and you don't really have control over the fans once you boot into Windows, but it works.

    I started off running Crysis in XP, and it was extremely hot. But I could tell a difference once I started using the fans. I'm playing TF2 and games like that now, and it still gets pretty warm, but definitely not hotter than 80 degrees C.

    hope this works for you :D


    BTW if anyone knows of a fan controller that works in Windows on a MBP please tell us haha

    The MBP can handle excess of 100 deg C for both the CPU and GPU diode.

    So far, I haven't found a program for windows to control the fans of any apple computers yet.

    I Know it can handle it, but with all the GPU DEATH ARRRGGHHH Threads, i dont wanna run it to the max.

    It got to about 90C Running Dawn Of War All Full at 1440 x 900, but still played smoothly :D

    The system will automatically turn off if it gets too hot. And I agree, the GPU death is pretty concerning. Kinda makes me glad I sold my MBP a few months ago, before these threads popping up. lol.

    Furthermore, these laptops are designed to take a lot of heat. If you wish, you can purchase a laptop cooler to cool the system down a little more. My system has reached over 100 deg C several times (laptop's at the genius being fixed cause it keeps hitting over 110 deg C even with max fans) and whenever it gets "too" hot, it goes to sleep.

    But if it gets too hot and sleeps, thats the exact conditions for GPU Death :( I'll just do the SMC Trick for now.

    I haven't read all the stuff on this GPU death thing but is is possible due to the extreme heat and extremely fast cooling that causes the diode to be damaged? I know I had hardware fail due to extreme heat then cooled down (20-40 deg C within a few seconds) fast.
