Good cooler with a few quirks

I bought this cooler to use with my ASUS Sabertooth Z77 motherboard and Intel i5 3570K processor. The cooler mounted fine with the thermal armor (for those familiar with my mobo) and with to sticks of Corsair Vengeance 4gb RAM. The cooler will block the slot closest to the processor but the other 3 are fine. The two fans are held on to the cooling fins with some metal wire-like things are can be kind of frustrating to get on. That''s really my only complaint with the cooler. Cores are idling around 36c from about 42c with stock cooler. Good buy but the mounting process can be difficult without a second pair of hands.

Without a doubt, the premier cooler on the market. Very good craftsmanship, and was a breeze to install.
Oh by the way, my temps on my i7-860 are insanely low!
