Hello friends PC, have this CPU cooler built into the computer by my son, when in it's always hot here because gamers. Thus came to us only a powerful cooler in question. That part is really huge, the installation is not so simple for the reason there. My son has installed an AS-770 rock-DE motherboard in his PC. First I had the power supply is the place above the Mother Borths dismantle, as in most of the two was Graffikkarten and last of the old CPU cooler AMD boxed cooler with a processor with this was and louder. Now the fun went out, the bracket who were there for an AMD motherboard, would not be turned so easily placed on the holder of the CPU. I have the cooler once used for testing purposes without giving cold paste on the CPU, only good, must remove this two more times, to re-adjust and adjust clamp to achieve the necessary holding pressure. When everything was OK then, I could give it the cooling paste and install the cooler ready. Man, man's part really just fits into the case plenty of space is there really no longer, well this is my son has a perforated casing perforated with dust fishing nets and PVC sheets in order to be flexible in the air intake for the radiator. The assembly line for the mains rectifier installation was partly quite tricky, because as already mentioned, remained fairly limited space. Finally, I have placed the two Grakas and everything again pied. Then the test run only once with an open side panel, so really great, very quiet running, due to the size of the fan and no helicopter noise. Viewed in retrospect when my son so now gambles his graphically extreme games, no volume problems with this cooler. Conclusion: Can this cooler recommend even if the installation is a little tricky, but you will later compensated by a good and quiet, functioning cooler which also priced right goes, hence a strong buy recommendation from me (5 Stars).
