I am very pleased with the Hyper T4! The cooler keeps my I7-4790K in a well-ventilated Big-Tower housing in idle at 26 °, under high load at 65 ° (measured with HW_Monitor 1.25). However, I must say that I have taken the opportunity, a second 120mm fan (be quiet!) To be mounted on the other side of the cooler, which (is appropriate mounting kit included) absolutely quickly and easily walked. The mounting of the cooler itself is run on the whole even without major difficulties, is already a pretty big unit where you have to be careful and a bit fiddly securing the retaining clip is always :)! Despite its size, the first DIMM slot is not blocked on my motherboard (Asus Z97 Pro)! I also like that the backplate can be adapted flexibly to various socket sizes (the "arms" can be in and out) and is not glued. One Wiederverwndung on another board (for example, base 2011) So there is no obstacle. The assembly instructions I found personally kept a little short.
So all in all a super fan at a very good price / performance ratio! Unrestricted recommendation from me!
