NoFan CR-80EH Passive Heat Sink Review
Up Close: Packaging and Overview
The CR-80EH comes in some very colourful packaging with a large blister window flaunting the form of the cooler within. The packaging also informs of the various compatibilities and key features of the CR-80EH.
First impressions of the cooler are that it appears to be a giant copper shuttlecock without the sproingy bit on the bottom. We say giant as at first glance it appears huge, in fact the CR-80EH is only 113mm tall. Perhaps it's the 155mm diameter combined with the height that gives us this impression.
Unlike conventional coolers which tend to use aluminium fins as a heat dissipation surface the CR-80EH uses copper wires, giving an overall heat dissipation area of some 97,157mm squared. This figure is achieved in the main part by having not one but two layers of wires in the frame, with rigidity and stability being provided around the upper circumference by a black circular bracket.
The CR-80EH does not appear to have heat pipes conducting the heat away from the contact plate and towards the dissipation wires. Instead all the wires appear to be collected and most likely connected into a layer at the base plate.
