| Category |
The Siberia is a cooler designed with HTPC and midi tower cases in mind, since it follows a top fan design. However Glacialtech has added a second lower fan, smaller than the top one, resulting to what we usually call a " push and pull" configuration. In order to get the optimal performance, you'd better adjust the RPM of each fan independently.

• Copper base
• Fins with high heat exchange ratio
• Multi-platforms (Intel LGA775, 1156, 1366, AMD AM2, AM3)
• Easy to install.

- Retail package
The Glacialtech Siberia heatsink ships with three different rear motherboard support brackets and a couple pairs of metal clips for Intel or AMD platforms. The Intel socket 775/1155/1156 mounting brackets can be used for any Intel socket and screw into place with spring tensioned collared screws. For AMD motherboards, Glacialtech use metal brackets which accommodate socket AM2/AM3 platforms.
The cooler uses two PWM fans in a "sandwiched " configuration. Between them there are the aluminum fins. To manage heat dissipation most effectively, the two PWM fans should be generally operated at different speeds: 800~1400 for the top fan and ; 1300 RPM for the bottom one.
The Glacialtech Siberia heatsink stands 122mm tall and as you see in the picture below, the bottom-most fin being 68mm above the CPU socket. The heatsink has six heatpipes positioned side to side where they make direct contact with the processor and expand outward before intersecting the aluminum fins.
The saw-tooth leading edge of the fins as well as an extra 10mm thick aluminum fins section on the top of the cooler's base offer some extra cooling.
Viewed from the side, the staggered profile of the Siberia heatsink allows a large footprint (149x146mm at the top edge) to clear adjacent board components below.
The nickel plated copper base of the Glacialtech Siberia heatsink measures just 30x40mm in size and soldered to the six copper heatpipes.
Below you see the nickel plated copper base of Glacialtech's Siberia heatsink, which has a sanded finish and it is flat:
- Installation
The Glacialtech Siberia heatsink ships with three different rear motherboard support brackets for the Intel socket 775/1155/1156 mounting brackets as well as the AM2/AM3 platforms only. It is recommended to take the motherboard out before installing the cooler, since it requires a backplate installation. The cooler screws into place with spring tensioned collared screws.
Although the Siberia heatsink allows a large footprint (149x146mm at the top edge) to clear adjacent board components below, it may interfere with your installed memory modules, especially if they feature any heatsink:
Above you see the Siberia heatsink spinning in dark, but we are not sure that the selected lightning effect contributes to an overall "cool" look. Of course, this is just our opinion :)
