Rampage IV Fan Control

[InoSiX]

I seem to be having trouble controlling my PWM pumps inside windows. I have no interest in using the bios do this for me, and want to make the adjustments in the OS. Using Speedfan, adjusting say the CPU fan speed (I have a pump connected there), does not seem to affect the pump at all.

Is it related to settings in the bios?

It's more likely your fan isn't PWM enabled, see the explanation in the link below, it may help:

I actually have one of Swiftech items, the apogee drive II with a MCP35X on it. I have it plugged in on the CPU pin on the motherboard. The device itself is powered by molex, but also has a 4 pin connector that is on the CPU fan pin header. Additionally, I have two more pwm MCP35X on the OPT 1 fan header. I cannot control any of them. I have tried disabling all points in Q fan under the fan option in the menu. Is there something I am doing wrong?

Also, thank you for that reply. Although I have seen that exact page before, I do appreciate the effort.

Did you ever come to a satisfactory solution? I too have struggled with speedfan to no avail.
