After a number of comparisons I decided spontaneously for the funny titled EKL Alpenföhn United Clock'ner.
As motherboard comes in my PC ASUS P5E used.
The Rebel 12 Economy serves as a shelter around the hardware.
Actually, only 3 points are worth mentioning:
== THE PRODUCT:
Huge! Just huge! The processing can actually nothing to be desired. Because let the fins bend very easily, you should somewhat more cautiously deal with the heat sink.
== THE INSTALLATION:
Since the case has a lot of space, there was no space problems upwards. However, there were certain incompatibilities with the ASUS P5E! The cooler can be here only with some effort.
If the fan of the radiator to blow the case back, several lamellae present on the motherboard heatsink would here / are shortened bent because no space is available between the bracket and the bracket the fins!
== COOLING:
What can one say? Bombastic!
The 12cm-fan rotates at leisurely 1000-1200rpm and is not heard. My Q6600 running while in idle with 25-28 ° C and under load the temperature still remains at 35-38 ° C !!
Conclusion: The majority Clock'ner is really only recommended and needs behind something more common / known coolers not hide! On The Contrary! Price / performance is simply unbeatable and comforting about something tedious assembly away!
