Very quiet, perfectly cooled but is very high!

I installed this cooler there one week instead of a Noctua nhc12p SE14. The result is perfect. I do not hear (as noctua the way) but much better cools my core i5 3570K pushed 4.4ghz (I from 70 ° to 55 ° in load, the Noctua chooses wasnt the best to push the processor) .

I have a case against the change because it is really high! it takes a really wide box to place it. 171mm instead of 160mm which is pretty standard max.

Ei you have the correct case (me define R4) is perfect.

And thank you to the seller to contact and speed of the order.
