Probably one of the best air coolers

Really huge, the part - and the proverbial!
Installation was straightforward in my opinion - can not tell whether the system is also designed so exemplary with other manufacturers.
After installation ever looked at the vitals of the CPU: Effective 16 degrees lower temperature is measured, even though the previous cooler (with single fan) was also not bad ...
Of course it has its price, and you should really check beforehand whether he (compatibility lists motherboard and memory available on the manufacturer's side) and in case it fits's motherboard, so there are no long faces after purchase.

With me it runs unthrottled, thus the fans are at high CPU usage while audible, yet never intrusive.
Who wants it even quieter (at the expense of a few degrees more CPU temperature) can indeed use the "Low Noise Adapter".
Really effective product that I can fully recommend accordingly.
