Phononic Hex 2.0 Peltier CPU Heatsink Review
 The Cooler
Measuring just 125x112x95mm (HxWxD) the Hex 2.0 is certainly compact and so should lend itself well to SFF and HTPC builds. Â Peltier workings aside, the upper part of the cooler is actually a traditional twin tower style Aluminium finned stack. Â Each of the stacks has four heat pipes passing up through it, with the pipes originating at different layers within the contact plate assembly, making for a total of eight heat pipes in total.Â
Â
In order to work properly the Hex 2.0 must be connected not just to a 4 pin supply for the 92mm fan, but also to a 6-pin AUX Graphics cable, as well as a mini USB which is used to enable the Hex 2.0 control dashboard.
The top of the cooler shows the capped heat pipes protruding through the upper Aluminium fins, with a central black plastic shroud separating the two towers.
Â
A high quality of work is evident on the whole of the cooler, not least the contact plate/Peltier assembly.

This shot gives us a close up of the temperature sensor that determines at which point the Peltier side of things will kick in.
