TPU noticed that Thermalright has created the AXP-100 Black Stealth Edition, a new version of the AXP-100 with a matte-black look, possibly ceramic-coated. Thermalright is giving away three of these coolers in its new contest.
The AX-100 Black Stealth Edition retains all other specifications of the original, except its matte-black (possibly ceramic-coated?) aluminum fins, matte-black heat pipes, and black copper base. The C-type heatsink uses six 8 mm-thick heat pipes to convey heat to an aluminum fin stack that's arranged along the plane of the motherboard, which is ventilated by a 140 mm fan.
