Very Nice except one thing
Since no one here mentioned about this issue, I thought i should write it down so that it may help others thinking of buying this heatsink. I am using this heatsink on 5820K cpu and it gives me quite an impressive result. My case is Enthoo Luxe and the cpu idles around 30C - 33C and loads around 60C - less than 70C. And I am only using one fan in the middle. Temperature wise, this heatsink is quite good. Though, there is one design issue I found. I was moving my place to other country from UK and I have crated my PC too. I chose sea freight and waited for a month to arrive. When I have received and opened the case, the cpu heatsink was significantly bent towards rear. This was due to the fact that Enthoo luxe was boxed in such a way that rear was facing down. I have never thought that metal heatsink of this kind bends that much. I bent it back to the way it was eventually but I am still too scared to try turning on the computer. This is a good heatsink but I don't think that the company thought of this kind of scenario where some cases are packed differently from others. The bending issue was obviously caused by the design of heat pipe allocations. Luckily, my second pc, which is also in the same case model, with BeQuiet Dark Rock pro 2/3 was not bentIf you are thinking of shipping your desktop elsewhere for moving out, then I don't recommend this item. Otherwise, this is a good heatsink I must say. Hope that helps.
