A criticism of the Freezer Xtreme (Rev.2) was that the cooler was very heavy and rather large to be relying on a simple four push pin mounting system. The Freezer 13 is lighter and smaller and while this will immediately alienate a portion of the audience reading this, it is rather refreshing to use such a simple system for installation.
It took literally 30 seconds to fit the plastic mounting bracket and the four push pins are strong enough to feel as if they could deal with heavy handed abuse. They can be used for both AMD and Intel platforms, although we are using an Intel Core i7 920 and ASROCK 1366 slot motherboard, seen above.
Once the plastic bracket is fitted, then the cooler needs to be positioned for two screws to be attached. At this stage we need to remove the 92mm fan bracket to get access to both sides.
Once both screws are tightened then the plastic fan shroud can be refitted. It is important to ensure that the fan is pointing either upwards or to the right in your chosen chassis to create a strong down/up or right/left airflow. As you can see in the image above right, the cooler doesn't block any of the ram slots either (regardless of mounting position), a problem with some of the bigger heatsinks, especially with memory using oversized heatspreaders.
Above, we can see the Freezer 13 paired with an overclocked HD5870 and Accelero EXTREME Plus. Above, installed inside an Xigmatek chassis.
