Who buys these coolers should first times - at least roughly - measure how much space he has in the housing available. The very considerable depth is too much for many housing. This is but I think a matter of course.
For installation: Unlike some of the previous speakers, I found the assembly instructions quite easy to understand, but I have read only the part of my base (1150). In addition, the manual is in English only, who does not understand the can for. B. assist a tutorial video on one of the many online video portals.
It is however to be observed: The installation is usually recommended only with removed motherboard, so far you have not a lot of space in the housing. I have carried out the installation in the fully assembled motherboard, which is why I needed about 30 minutes for the installation. I am convinced that I needed with removed MB no longer than 5 minutes (you have to say that I've previously only performed once a cooler exchange, and that was with an AMD socket and much more compact cooler).
Who still wants to perform with installed MB installation, should note the following: memory should first be installed in my board, for example, 2 of 4 slots are hidden by the cooler.. It should also look to see if the port is covered for the fans. For me that was the case, so I had to join the installation of the heatsink CPU fan against. In addition, you have to have space in order to screw the screws on the sides enough. I had had a 1cm wide gap for available, so I had to fix my tape on a long screwdriver, nuts, and then placed in a precision job on the screws. Necessity is just creative.
Now for performance: For me the cooler perched on a i7 4770K @ 3.5GHz (ie at standard clock). When stock cooler I had this in idle 40-45 ° C, to load quite fast over 70 ° C. By Alpenföhn Brocken I have now in idle 26-32 ° C, to load a maximum of 55 ° C. The fan I have here in idle to 40% power, from 50 ° C temperature at 60%, it is on request so even more. The volume is doing fine, he is not super-silent, but on the one hand allows the fan if desired exchange quite easily, on the other hand are my other fan (graphics card and housing) no silent fan, of that I would so or so do not benefit from a silent CPU cooling. "According to" the provided of Alpenföhn 120mm is no way.
One should be said: My case measures 18.8 cm in width, the heatsink fits exactly - and I mean exactly - in. Had it 1mm higher (or lower, depending on your perspective), I could no longer attach the housing wall. A real lucky purchase.
Who is still interested: My MB is an Asrock Z87 Pro 3, my body a K280 from Cooler Master. In this combination of cooler fits definitely, albeit very, very scarce.
