Installation is quite briskly by equip. Is also very easy with removed motherboard. That the motherboard needs to strengthen the assembly, is perhaps the only drawback to the fan. However, I had anyway the same time ordered a new CPU and a new motherboard. Therefore this was so anyway expanded.
You can infinitely adjust from 0 to 100% of maximum speed in% increments the fan after installation in the BIOS. At 100%, he is immensely loud and useless.
With me he now runs with only 35% speed, is completely inaudible, yet cold enough.
