I then switched to a different fan controller, MacsFanControl (. Second, I followed suggestion and downloaded smcFanControl, but unfortunately it didn't help nearly enough. I then tried three of the solutions mentioned in this thread.įirst, I tried resetting the PRAM, but this had no effect at all, as far as I could tell. Ultimately, I ended resting the machine on top of a medical cold pack just to keep it running for an hour or less at a time.
But whenever I used the MacBook for long periods of time in hot temperatures, even this proved to be only a temporary solution. The computer felt quite hot, so at first my solution was to shut it down for 20 or more minutes to let it cool off. Whenever I was working the CPU heavily while the ambient air temperature was hot (20-25C or so), first the monitor would repeatedly shut off, and soon the entire machine would spontaneously shut down completely. My MacBook never had this problem until I replaced the magsafe adapter with an non-Apple charger (the Ostrich Replacement Macbook Charger 60w Magsafe L-Tip Power Adapter Charger) during the heat of summer. I installed the software and haven't had a "go to black" moment since.

The solution is a simple FREE software download called SMCfancontroller that turns your fan on at specific RPMs, and turns it off when you aren't overheating. I had to replace my factory isntalled drive because it failed.
A lot of Apple's early drives for iMacs and MacBooks were really cheap and the sensor failed. This also happens on factory installed drives when the temperature sensor goes bust. However, if you've changed your drive like I did, and replaced it with a drive that did not have a temperature sensor, thent he fan controll gets all confused, doesn't turn on properly, everything heats up and then shuts down. There is a temperature sensor in the drive to supposedly prevent this. The SMC fan is not cooling down the system which is then shutting down because of the heat.
