Property me 'time due to the reviews indulged these expensive cooler, it would not make again. Why? Let's start at the beginning: Technology Super great, makes a stable mature impression. For the four star and only for that. The little picture on the built-in instructions are a little small, but you will already figure out what is meant. Built-consuming with motherboard expansion, but one always has the impression that you got something valent value for money. so far so good. I want to compile my PC, which you do not hear as possible. Therefore this purchase. This component was, however, by far the loudest (!). An audible hiss comes through the housing to the user's ear, the fan rotates high speed. Now good advice! or not? With a control potentiometer allows the speed, I guess' times by half, reduce. Now is really largely rest without my (or rather the CPU) temperature problems. Conclusion: I would have one-third of the money managed with a standard cooler. But you only treat anything ... The Fairnis sake must be noted that with this powerful cooler compared to the standard chiller at the same speed the CPU, make sure at least 5 degrees -eher several stays cooler, already clear.
