As other manufacturers can wrap up warm

I have added myself and found that my old CPU cooler is not suitable for recently new CPU (Intel Core Quad Q9550).
My motherboard is an Asus P5WDH deluxe 775 socket.
Installation: the motherboard has to be removed, but for experienced users no problem.
On my 775 motherboard, the installation went quickly, the guide has for all the pictures and information at hand, in German.
The fan has 4-pin connector.
The heat sink does not interfere with hardware components. That's very important for me because I occasionally on my hardware components do something like RAM swap / test, hard disk Installing / removing etc.
My Intel Core Quad Q9550 is just at 20 ° C, under load with Prime measured at 40-50 hours.
Before the CPU was 2.4 GHz E6600 always at 50-60 ° C with Intel Core2Duo.
The fan is pleasantly quiet and barely audible, personally bother me more the hard drive noise.
From quite clear to me 5 stars, this slim CPU cooler Bequiet in my opinion is the best!
