Have 4 pieces of these monsters integrated into my water cooling. Are a Zahlmann Lüftersteureung connected and dimmed to the absolute minimum. The fans can not be heard and the cooling function on my 2 240 radiators is just fantastic, my overclocked i5 4570k is even in the stress test settled below 60 degrees. As I said, it can be heard from my system no Muks. Who accommodate such monsters in his system should access.
