"Rated for heat loads of up to 200W according to the manufacturer, the Arctic Cooling Freezer 13 is a relatively compact sub-130mm tall heatsink.

The Freezer 13 mostly delivers on the noise front but it's compact design and 92mm diameter - not 120mm diameter - fan limit thermal performance to the 'average' region according to Frostytech's reference charts, even where heatsinks of an identical height are explicitly compared. Computer enthusiasts with compact PC cases will probably like the Freezer 13 though."
