I am building my first computer and I have been planning this for a couple months so I have a lot of knowledge and my parts are compatible. I was looking for CPU fans I keep seeing MM and what what it means or does and if it is suppose to be compatible with my motherboard or CPU.

CPU: Intel Core i3-3220 Dual Core processor : http://www.newegg.com/Product/Product.aspx?Item=N82E16813157315&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-Motherboards%20-%20Intel-_-ASRock-_-13157315&cm_sp=&AID=10440897&PID=3938566&SID=

Motherboard ASRock H61M: http://

? Only thing that comes to mind when looking at fans and seeing MM would be mm. As in the size of the fan. 120mm, or 92mm. As I said this has to with the physical size of fan on the heatsink. You might also see cfm, would be relate to the amount of air the fan can move. The heatsink as a whole might also have a TDP rating, which is the amount of heat it can handle/is rated for.
