Equipped with two fans, one above the large 122x146mm aluminum cooling fin array and the other below it, the Glacialtech Siberia heatsink packs a lot into a thermal solution that stands just 122mm tall, roughly 145mm square. Six 6mm diameter copper heatpipes support the two differently sized translucent blue fans which hang from ~45 louvered aluminum fins, giving the Glacialtech Siberia a somewhat top-heavy appearance. The heatpipes are packed closely together and covered by copper heatspreader, rather than left exposed.
