Can someone tell me if there is a way to control what RPM my fans spin? I dont really want to control the voltage either. I mean like software, or some kind of bios setting. I have an ASUS P2b 440bx. I want to crank up them rpm to about 6000 each.
Had it on my old BM6, worked great, when the temp was below 30 C the cpu fan went down to half the speed, the noise was greatly reduced, under 27, the fan stopped! Of course it spinned up again when the temp raised.
There are those who stink, and those who use deo, But I, for one, refuse to choose between the two!
(No offence Xriz =)
This is the thing, that program just takes advantage of APM features. These calls are all handled by the BIOS, and your motherboard has to support these settings AND all these fans must be connected to your motherboard.
These settings simply reduce the voltage delivered to the fan by 1/2 or turn off the voltage. I seriously doubt there is an option in the BIOS to overvolt your fan.
But if youre into getting your hands dirty and modding your power system, I believe there is a -5v lead on the ATX connector. Now placing the +12v on the red wire and the -5v potential on the black wire of your fan creates a +17v potential, but I seriously doubt anything but a high quality fan could take this. Plus you would have to soder a lead out the back of the ATX connector.
Bladerunner, I got the impression from his post that he wants to "overclock" his fans. He just wanted to do so without messing around with wires, something you really cant avoid. So I suggested the easiest thing he could possible do, and it will pump his fan voltage from 12v to 17v, not 7v.
The P3B-F does (dont know about the P2B)have "Smart Control" at least thats what I think its called. I dont use it but it regulates the voltage through the software and does lower the RPM if its not hot. What I noticed is the RPM would lower but within a couple of minutes it would be right back up to full speed. Thats with the system idle, so if you ask me it doesnt work very well.
Titan2782, I think the concensus is that there's no software that can increase the voltage to your fans and or increase the RPMs that they run at. Remember that the 4 pin leads from the PSU supply 12 volts. And you would certainly need to splice wires to get them to supply anything more then 12 volts.
