Silverstone Heligon HE02 Fanless Passive Heatsink Review

The Silverstone Heligon HE02 is being sold as a passive heatsink for sub-95W TDP processors, so today on Frostytech we'll put this big, boxy, silent heatsink through its passive paces. No fans will be used in the testing, just good old noise-less convection cooling. We should note that wire fan clips are supplied for users who wish to add two 120mm fans. Given the Heligon HE02 heatsink stands 151mm tall and has a footprint of 170mm x 130mm, adding 50mm of width onto that 130mm wide frame is inevitably going to be a challenge for most motherboards... Never the less, the option exists.

Silverstone's Heligon HE02 heatsink weighs in at 990grams and installs onto Intel socket LGA2011/1366/1156/1155/775 processors and AMD socket AM2/AM3/FM1/FM2 CPUs. It retails for in the neighborhood of $70 at NCIX.com.

Like the Heligon HE01 heatsink Frostytech previously tested, the Heligon HE02 is asymmetric - meaning the CPU base plate is not centered on the body of the heatsink but positioned off to one corner. This novel approach aims to make the heatsink more compatible with motherboards having excessively large VRM heatsinks or memory slots positioned too close to the CPU socket. Looking at the center-point of the CPU base plate from below, the body of the Heligon HE02 heatsink extends ~54mm down, ~94mm left, ~74mm up and ~74mm to the right. The lowest fin is elevated 41mm above the CPU so there's a decent amount of clearance for motherboard components.
