Windows 7: Cooler Master 212 Plus Fan Issue

Regarding PWM connected fans stopping for periods, this has been reported when the CPU temps are low and no air flow is needed as in start up and or low ambient room temps. For me I want my fans spinning all the time moving air though the case and out.....but that's just me.

Yea, the fan is now on the proper side of the heat sink. All air is being pushed towards the rear of my case and being exhausted.

So what my fan was doing was normal? I'm asking this cause it is brand new and i'm curious whether I should RMA it or not.

Also, is there any way to make it spin 100% of the time while plugged into the CPU Header?

Yes the fan can stop for brief periods if the cooling fins are keeping the CPU stable and within temps. If as you say the fan is new then I'm sure you're fine. Good catch getting the fan pointed in the correct direction. I would either turn of the PWM feature in the bios or better yet just move the fan plug from the PWM header to a std. fan header which there should be one handy on the mobo. Lastly if you can find the std. fan header then do as I do and run the fan directly off a free 12v molex connection off the PSU, this will require on of these.

You may have a perfectly good CPU fan, but even if you're confident with it, you may want to set a safeguard, just in case.
Enabling the "CPU Fan Fail Warning" in the BIOS is a good idea.

I will just connect it to a standard header. My question is though why do you recommend this 12v connection over the motherboard?

I actually saw this option last night while looking through BIOS and was going to ask about it, read my mind! Thanks

Deception,
I like to keep all unnecessarily voltage off the mobo, that's just me. I run a lot of fans and a lot off stuff, plus I also have a fair OC so to me it just makes sense. It also adds to a cleaner mobo but when you are talking just a CPU cooler it's a fairly mute point.

I have two. It can stop and start.

Be careful with blanket statements. Some that do an excellent job of cooling with heat pipes don't always run. My server is running an i3-2100 with a 212+ on it, and between the cool processor, excellent cooling in m case, and the heat pipes, my fan doesn't run all the time, either. It runs more on my i7 system, but still not constantly.

I've never seen a cpu cooler fan stop.
