Cooler Master 212 Plus Fan Issue

I thought someone said it is supposed to start and stop?

A cpu fan is never supposed to stop.

Well actually.. I flashed my BIOS to the most updated version yesterday and I haven't seen it stop once. Do you think an older version of the BIOS could effect that?

Turn everything off and then switch the fan connector to a case fan connector. Turn the computer back on and see if the fan runs. Use your motherboard manual to locat a 12v case fan connection on your motherboard.

My fan works plugged into the CPU header. I don't know if you missed that or not. Let me know if you want me to try this or not after knowing that.

Deception,
I would review the CPU cooler installation instruction as the fan should be pulling case air from the front and pushing that air through the fins towards the rear exhausting case fan. Like mentioned I would replace that fan with two premium fans and if you get Noctua's they are so quiet that even full speed they will barely be audible. Set up the fans in a push pull arrangement and then plug them directly into a free 12volt connection off the PSU and bypass the PWM plug all together.

I flipped my CPU fan to the opposite so now air flow is proper. My fan has not stopped since I did this AND flashed my BIOS to the most updated version.

I'm curious whether you are talking about replacing the CPU Fan or the Rear exhaust fan? I am more interested in this option because it probably provides better cooling. Let me know.

They're talking about replacing the fan on your cpu cooler. If it's working so far, then just keep a close eye on it. I've never heard of a problem with the bios not running the fan, but you can't rule it out. Do you have the airflow of the cpu cooler blowing towards the rear exhaust and out of the case?
