Fan speed auto control or free
 

I was browsing a LCD forum, when I came across a post about auto fan speed. There is a program that will automatically adjust your fan speed to keep a certain temperature or, you can set a percentage value for fan power. It works using the PWM concept that Brians talks about in his quiet fans article. It will work on many modern mobos. It worked great on my IWILL ka266. The address is http://www.almico.com/speedfan.php. Enjoy!

yeah I've heard about it before, it is really cool, it doesn't seem to be happy with my laptop though which is a real bugger.

It works well with my VP6 though, it actually allowed me to run passively in win2k while just browsing on the net

I was having fun with it on my IWILL untill I tried my took a risk and tried my 120mm fan. I burnt out the header. But thats no big deal. I partly why I have a digidoc

just cut the red and black leads to the fan, and feed the red into the yellow cable at a molex connector and the black to either ground at a molex connecter, and leave the rpm thing on. You won't get pwm, but you can still run powerful fans on any mobo header, and it is sometimes possible to get rpm readings on a burnt out fan header

The point was to get PWM, but now I just run it on 7v. It is a delta 130cfm and has no RPM sensing. I wish I hadnt burnt out the heads, because I had a couple 80mm fans I wnat to use the PWM on.

does this program burn out fan headers or something ?

nahh, the 120mm was just pulling too much power off the fan header

Speedfan works with MB's that already have PWM on them. Amazing, all this info lately on ways to slow your fan down (rheostats, PWM) and it turns out some MB's already have it!. In fact, in the press release for one of the new Asus 533MHz P4 boards, it's listed as a feature!

asus call it q-fan, they have 5 mobo's with it now
