Guys

I always use the Swiftech MCX35 pumps with PWM Control, even it's enabled on BIOS and Silent when restarting pumps go to the fastest speed and only start slowing after entering windows. Any solution for this ? i have a controller the lamptron CW611 but is 3 pin, it has for pump control but i read that PWM is a different and more precise pulse of volts and good for pumps.

Thanks a lot
Sergio
