I had several radiators processors (ARCTIC ALPINE 64 PRO and ARCTIC COOLING Freezer 64 Pro) that mark the last of which was until recently used ventilated after several iterations of processors and for a number of years. A "hum" was heard because the fan became loud (probably due to wear of the axis), taking into account the activity of my PC almost constantly in function, it was easily predictable, so more than satisfied with this brand for durability. This new model is aesthetically a success with its chrome effect rather compact height it goes smoothly with my InWin housing with side fans in place, congestion side width with respect to the RAM (4 slots) on a Gigabyte MA 770 UD3 it goes with standard size modules (Corsair XMS2 6400 in my case so a higher than standard hair barrettes with their aluminum radiator). The fixation on an AMD socket in my case is very simple, you just have to screw the two supplied brackets that take in the tabs on the processor socket (no need to replace the bracket on the motherboard) the thermal compound is already applied evenly, so a very nice. In conclusion a very positive reviews on this product.
