Manual CPU fan control

[Magnarider]

I need to find a way to set my CPU fan control to full speed without the use of hardware but be able to monitor it witht he motherboard. I have tried using my BIOS and software but it keeps resetting itself everytime I reboot. Is there some type of switch that I can install that will allow me to set the fan at high speed while still be able to monitor its rpms with software? So I cant use a molex adaptor because that would not allow the motherboard to monitor it.

Any ideas?

I was thinking of using this but if its plugged into the motherboard header will it be software controlled or will it be controlled by the psu through the 4 pin molex adaptor? I dont want the computer BIOS or software to have fan control I only want to be able the monitor the fan through software and not control it with software?? http://www.newegg.com/Product/Product.aspx?Item=N82E16812311001
