Well, I'm trying to quiet down my computer, and looking to replace the stock cooler on my MSI GF4 Ti4600 with something a little bit quieter. And I'm wondering what's the difference between the Zalman zm80-hp, the zm80a-hp, and the zm80c-hp?
The C has the ability to mount an extra fan on it to increase the cooling, and it also has a couple bars to hold it down and keep it from falling off. Get the C, its most likely worth the extra $4 or so it costs.
