The Accelero S2 is fully passive heat-pipe cooling unit that has strikingly large and widely spaced fins (31 fins altogether). With its size and thin fin design arrayed closely along two copper heat-pipes - which has the heavy responsibility of conveying the heat from the graphics core - the Accelero S2 resembles metallic Venetian blinds rather than something that could be feasibly attached to a graphics card. The tall height and large size of the cooler belies the fact that due to its substantial aluminum content, the Accelero S2 is actually quite light, weighing in at only 202g. Hence, despite its bulk, which makes it unsuitable for low-profile enclosures popular for HTPCs, there is no danger of its weight warping your graphics card. Included too are eight small aluminum heatsinks for your card's memory chips, making this a very complete cooling package.
