Taking a closer look at the bottom of the Freezer 13 PRO, shows a small 50mm fan installed. This helps to ensure that there is adequate airflow around the socket area, which can end up being a dead zone. This little fan is PWM controlled, and has a tail connected to it so that it can share use of your motherboard's 4-pin connector and fan speed controlling capabilities.
Mounting equipment is included for both AMD (754/939/940/AM2/AM2+/AM3/AM3+/FM1/FM2) and Intel (LGA775/1155/1156/1366) sockets.
The Intel mounting system used by the Freezer 13 PRO involves using plastic clips and pins to attach a mounting frame to the motherboard. The wings on the base of the heatsink are then screwed to the mounting frame. I found this mounting system made the Freezer 13 PRO very easy to install.
The moderate thickness of the Freezer 13 PRO cooler meant that the RAM slots on our test motherboard were not covered, and high profile memory could be used. While this may not be the case with all motherboards, I'd assume that most motherboards would allow for at least two RAM slots usable with tall memory.
The base of the Freezer i30 is more spartan. It's basically just a piece of aluminum going accross the heatpipes, with wings on each side used for the mounting mechanism.
Only Intel sockets are supported with the i30. The AMD equivalent of this cooler is called the Freezer A30. Socket support for the Freezer i30 includes LGA1155/1156/2011. The mounting system involves affixing a backplate to the back of your motherboard, then screwing mounting arms to it on the top of the motherboard around the CPU socket. The Freezer i30 would then be secured to the mounting arms. I found it to be a bit tricky getting a good mount with the Freezer i30. The first two attempts at mounting the Freezer i30 resulted in big variations in CPU temperature, with the third mounting attempt being successful. The variation in temperature between the three initial mounting attempts was 15 degrees celcius on load with our overclocked test system.
There were no spacing issues around the socket area of the motherboard with the Freezer i30 installed. The first RAM slot on our test motherboard was covered by the cooler, but RAM of standard height will have no problem fitting.
