I feel satisfied in the purchase.
The cooler is stable on my I7 2700K, despite the lack of indication of 1155'er base.
Only the structure of the fan bracket to the motherboard was a little tricky, because this is really screwed together under tension.
One should take care that you have enough space for RAM on the motherboard because the fan is very large and, where appropriate,
Slot covers (a like mine).
Also, the size of the motherboard to keep away so that the CPU cooler also fits into the case.
Best before remeasure the housing. Then one is immune to surprises.
Conclusion:
-leiser fan
suitable -for overclocking
Disadvantage:
-Can hide RAM slots
