The be quiet! Dark Rock Pro 2 is an imposing cooler standing 166mm tall, 147mm wide and 138mm deep (6.5×5.8×5.4") and weighing in at 1.25kg which means not all cases can accommodate it and it will dwarf an mATX board.  The two fans are mismatched, one is 135mm and one is 120mm however [H]ard|OCP's testing proved that does not mean it is a loud cooler.  It's cooling ability is quite impressive and puts it at the top of the chart; unfortunately so does its $90 price tag which is higher than other competitive coolers.  If you can find it on sale it is well worth investing in.

"CPU air cooling and huge cooler sizes have become synonymous. One thing that is not synonymous with high end air cooling are muted sound profiles. be quiet! looks to remedy this issue with its Dark Rock Pro 2 CPU air cooler that sports a tremendous 220 watt cooling capacity all in that be quiet! package."
