Summary: AMD 8 core 8350 keeps it nice and cool, installation was simple on gigabyte motherboard. I didn't realize the standoffs had flat spots to align with the holes in under plate at first and had a struggle thinking something was wrong with the holes at first, you've got to look closely at them. Other than that it's a quality product, massive large and could pose problems for mounting in some cases (be sure to measure before you buy).
Summary: I had this in my old AMD system, it works, decently, installation is a bit cumber son, quality is lack luster, the fan mounting solution is bad, and damages the fins, the fan I had failed within a month, the fan is also very loud. for the price, I would not recommend this cooler, enermax makes some excellent coolers for the same price.
Summary: I had constant problems with CPU temperature while playing pretty much any game and eventually I said screw it and bought this fan while on sale. Haven't had a single overheat since. Although installation may be a little tricky for some (you need to access the back of your mother board) it shouldn't take too long if you know what you're doing. Another note is that for people with smaller cases this thing probably wont fit.
Summary: It's well designed and the heatpipes are in direct contact with the processor. However, the flaw is that the pipes are not exceptionally flat (looks like a belt sander was used by OEM). It was a bit awkward, but I lapped the heatsink for the sake of flatness and not a mirror finish (using flat glass + sandpaper, stopping at 2000 grit), and it keeps my 4.5GHz overclocked G3258 very cool (65C full-load, 35C idle - and with less than a two second temperature swing).
Summary: fits great, keeps my cpu's at like 30 to 40 under heavy loads, gaming etc. Fits no sure why they don't have it listed as so. Case wise would be the only issue to make sure to look at. Have two of these in two different setups, have never had a issue with either mid towers :) recommend getting another fan for the other sie :)
