Now you discover one of the biggest failings of the EVGA P55 series... Fan control (or lack of). The CPU fan header only speed controls 4 pin fans (yes I know every other brand of motherboard including Asus and Gigabyte allows regulation of speed with a 3 or 4 pin fan on CPU header). Furthermore other brands show fan RPM below 1000. FTW only shows fan speed if it's 1000rpm+
So, if you want to regulate fan speed with your 3 pin fans, you can only connect to sys fan and pwr fan headers. Set them to PWM auto and you can define your speed/temp ranges for both fans. To test it's working, set all the speed bands to zero, save and exit then go back into the bios. You should find the fans stop turning after a while.
What you can do is use Speedfan software to gain control of the fan headers but still you will only be able to regulate Sys and Pwr fan header speed. What you can do is make an adaptor or perhaps buy one to wire multiple fans to each header. That's what I have done.
