CPU fan not recognized properly

Old Fan: Stock fan on AMD 965 Phenom II BE 80mm
New Fan: ARCTIC COOLING Freezer 7 Pro Rev.2 92mm
Motherboard: Asus M5A97 AM3+

I decided to upgrade my cpu fan as my old one was pretty noisy, and it works, but in the bios it seems to think that the fan I installed is a chassis fan, and that I do not have a cpu fan anymore. It works pretty well when I'm not running any major programs- even at 1500 rpm it's only running at about 36 degrees as opposed to my old fan running at 2500 rpm and 42 degrees. The problem is that since it's not recognized as a cpu fan, it won't increase its rpm in response to the cpu's temperature. Any idea on how to fix this?

If not, where else could I ask?

    I know this seems obvious, but are you sure you plugged the fan on the Freezer 7 into the CPU Fan header? There are three fan headers right next to each other on that board and it's the one in the middle.
