" ... I didn't want to run liquid cooling but needed something that had equivalent level of cooling capacity. ... All in all, possibly the best air cooler available today. ... "

" ... I'm running an i7 5820k overclocked to 4.4GHz at 1.3V, and this cooler is keeping my CPU around 68-70C during a STRESS TEST! ... This keeps my cpu very cool and very happy. ... Performance as good as Noctua NH-D15. ... "

" ... Although a bit more expensive than a lot of other models, this fit with my build, and performance is great! ... "
" ... One thing to keep in mind make sure to tighten the screws till they are snug especially on the cross bar that holds this cooler to the board, because I did a stress test and my CPU was thermal throttling, but once I went back in and made sure both ends were snug, I ran the stress test again and the chip stayed plenty cool. ... "
" ... This thing installs easily - the instructions are clear and there are videos in case you get stuck. ... The especially nice thing is that they include a magnetic screwdriver for the final mounting. ... This makes life a lot easier as the length of the screwdriver and its being magnetic help to allow you put in the final screws. ... "
" ... The mounting is a little hard at first but works fine. ... "
" ... The mounting brackets fit onto the cooling fins a little too tightly, and I had to choose either using a tool to bend them into place (thus causing minor bending to one or two fans) or slicing up my hand. ... "
" ... Pretty easy install with heavy duty mounting pieces. ... "
" ... Make sure it will fit in your case. ... "
" ... I would say the hardest thing about the mounting is the fans and the clip system they have. ... It would be nice if they provided a little tool to help pop the clips off. ... You get a nice magnetic screwdriver in the box ... "

" ... Don't miss out on the removable caps that allow you to screw it onto the mount without cursing and tears. ... "
" ... BUT, you'd better check your case clearance. ... "
" ... Like I said, the quality is good, the metal for the fins is nice and thick unlike others I've had and there is no worry of bending plus the black just looks great. ... The only way I could get the cooler to properly seat on the CPU was to put a piece of heat shrink tubing in between the brace that screws into the bracket and the heat sink. ... "
" ... It's kind of big, but the black makes it look good especially in an all red and black build. ... "
" ... The material felt nice and solid. ... "
" ... Don't miss out on the removable caps that allow you to screw it onto the mount without cursing and tears. ... "
" ... From there, just line up the holes and screw it in. ... As you can see in one of my pictures, it is easy to bend the fins from using the clips if you are not careful, but also just as easy to bend those back if you wanted. ... "
" ... That being said, I swapped out the top fan and was able to mount two 120mm fans on my case's included fan bracket to assist directly with cooling. ... "
