Fan speeds and up and slows down while computer sits idle
I have BIOS version A07 which was supposed to have fixed this problem. But I still have the same issue. Any suggestions? I have alienware X51 bought on November 12 2012, running windows 7 64 bit.

Including the video card, I think there are 3 fans and 2 controllers.
At a pre-determined temp., they all speed up to the next minor level. Sounds like your idle temp is right on the edge of next level.

Apple desktops work basically the same way.

Which fan ?
Fan speed is determined by real-time cooling requirements ... not current usage (idle, etc.).

I am not sure which fan. How many fans are there in an X51 machine? All I know is that there is a fan noise that accelerates and decelerates with regularity within less than 15 seconds. But I am not running any applications. The system is just sitting idle. I guess the fan is related to CPU usage is it not? The fan just keeps on alternating between slow speed and fast speed within miniscule incuments of time. I figure if I am not going something that would heat up the CPU the fan should be running very quietly at an even pace. Or amy I wrong in my assumption? Is this the way this machine normally operates? Thank you for your response. I am Mac person. THis is my first pc. any assistance woudkl be appreciated.
