MCP35Xs Powering Up Funny

post #1 of 3
Thread Starter 
I have 2 MCP355s in another build and i just bought 2 MCP35Xs for a new build im working on.

I just got everything set up and filled and started bleeding the system, I noticed both the MCP35Xs do some weird power up, they spin then stop spin backwards it looks like then stops then spins up to speed.

My 355s dont do that and i dont have any friends with the 355X to compare to and theres nothing on the net about it, i just wanna know if its normal for this pump.

I tried a different power supply and molex connector and the same thing happens, so i have no idea.

According the the motion of the liquid in the reservoir, both of mine spin clockwise and never counter-clockwise. On PWM, the pumps start immediately at system power up and stop momentarily (liquid in the reservoir settles towards becoming motionless) before proceeding according to its PWM profile at the start of POST. On a singular Molex connection sans PWM, the pumps start at full RPM and stay that way through the computing session.
