Controlling the minimum speed of fans!
I had issues with my graphics card lately and it is usually fine, except when I am working in really graphics intensive application such as Motion. I read a lot about it online and apparently, replacing the card won't do much good. The reality is that it is overheating. The recommendation were to increase the minimum fan speed when I am working in these applications. A really cool third-party application called smcFanControl lets you increase the minimum speed of the fans. What is great about it is that it is still fully automatic. It will still let the system go above the speed that you set if it is needed. I haven't had any problems since. This application only works on Intel Macs however. You can learn more about smcFanControl or download it here on MacUpdate.
