The cooler does a great impression of the box. There is plenty of installation materials here, cooling paste and a sheet of A4 paper with the installation instructions. The installation manual includes several socket types, so you his base type must pick out at first. This is done quickly, then the very brief instructions (in English only, which does not bother me now) really is not intuitively understand. Since not all of the accompanying installation materials should be used, even the selection of a suitable material is a task in itself. With a good deal of creativity to the installation instructions I finally found after a beaten half an hour, as the cooler has to be installed and I have to say that I rumbastle lot of PCs and am quite technologically adept. Then it comes to the actual assembling what you have to remove the entire motherboard once to carry out the following work outside the housing can. The installation was very fiddly and much Fummelarbeit, I can not imagine that it gets someone who is not very patient, assembled immediately to me. When the installation is done, sits the cooler which brings quite a bit of weight and size on the scale or to the ruler, bombproof. The purple LEDs in operation are very nice to look at, if you have a suitable housing, I could have done without it. The noise during operation is fantastic, I hear almost nothing from the fan. The quality of the product can be seen in my opinion quite. In sum, the manual disaster, the assembly very fiddly and time-consuming accessories okay, operation, cooling capacity, noise and super seat.
