Strange problem

Last response: in Motherboards

I put this under motherboards because I don't know where else to put it.
I just recently bought and installed the Hyper 212+ aftermarket cpu cooler for my Athlon II x4 630 on my Asus M4A79XTD-EVO.
And what a great cooler, I have to say.

But anyway, when I plugged the fan into the 4-pin cpu fan connector near the cpu socket on the motherboard and turned my build on, the fan tried to turn, then stopped.
All the other fans and lights turned on. I immediately turned off the computer for fear of overheating.
I know that 4-pin connector on the motherboard should work because I was just using the stock cpu fan plugged into it a day ago.

So I tried plugging in my new Hyper 212+ cpu fan into a different 4-pin fan slot called pwr fan 1 or something and it works fine.
I was able to overclock and run the computer fine like this, although when booting up it gives me a warning about no cpu fan.

This would be fine for me except that the pwr fan 1 slot always keeps my fan on 100% speed, which I heard could be bad for the fan's lifetime.

Thanks

^ lifetime not really, are you "trying" to use Q Fan2 or any BIOS tweaking utility?

I'm not sure what Q Fan2 but I am using AMD overdrive if that's what you mean.

Get in the BIOS:
1. Power | CPU Q-Fan Function [Disabled]
<or> Install Q-Fan from {part of AI Suite} Download - http://usa.asus.com/product.aspx?P_ID=vk9Pqxby9MjO0WHm
2. Power | CPU Q-Fan Function [Enabled]
3. set [PWR Fan]
4. set CPU Q-Fan Mode [Optimal] or [Performance]

^ Just checking - "Q-Fan" was listed in your Manual; I assume everything is running.
