The Freezer 36 Black has a dense stack of fifty-nine black anodised aluminium fins measuring approx. 5 cm by 12.5 cm. It stands 159 mm tall, fractionally taller than the standard yardstick of Cooler Master’s most modern Hyper 212 but effectively matching the Noctua NH-U12S and be quiet Dark Rock and Dark Rock Slim designs. There will be some PC cases where this is too tall, typically small form factor designs, but standard ATX and mATX chassis shouldn’t pose a problem.

A black anodised aluminium top-plate shows off Arctic’s branding but we wouldn’t be surprised to see 3D printable detachable fascia plans appear in hobbyist catalogues. As-is, it’s a clean look for minimalist or ‘blank canvas’ system initernals.



A quick look at the underside exposes the 6mm diameter heatpipes. For the best thermal conductivity Arctic have opted for a flattened ‘direct contact’ approach to mating with the CPU heatspreader rather than an intermediate layer. From this angle you can also see the matte black coating to the heapipes and bracketing retention square.



Here it’s possible to see the recessed mounting points for one of the two 120mm fans. These spring-loaded recesses grip on to the screws affixed to the fan, holding it tightly.

The contoured fin cross-section on this side of the fin stack is also most clearly visible from this angle, a feature intended to reduce turbulence and improve overall air flow. The rear side by comparison is totally flat.



Finally here are the two fans. They conform to standard 120mm spacings so in theory you can swap them out for other standard 120mm fans if preferred. Note that there is no integrated noise dampening material on the heatsink or fans to reduce vibrations induced by fan operation. Fitting rubber O-rings between heatsink and fan should be possible should it prove necessary.
