I love hearing but I like even more where it is maintained. Yes Google and Bing can, but I spend so much time posting tips,with their link.
Lubbo's Fan Control is designed to be a speed fan controller for MacBook Pro Unibody (Nvidia) under BootCamp. It allows to control MacBook fans settings their speeds depending on the CPU and GPU temperature and it reports CPU and GPUs temperatures, current and target fans RPM.
ATTENTION: This program is designed and tested only on MacBook Pro with NVIDIA GPU.
On newer MacBooks with ATI GPU the GPU temperature is not checked.
On iMacs some sensors and fans are not used.
In any case USE AT YOUR OWN RISK, I'm not responsible for overheating or hardware damage.
Seems like it is limited to MacBook only users
