THE MACHO ZERO
The Macho Zero might be quite large but it's actually smaller than the HR-22 so it weighs 162mm in height, 140mm in width, and 102mm in length and weighs 710g.
The design of the fins increases airflow while the large hole in the middle is used to mount the cooler using the bundled screwdriver.
A total of 31 black nickel plated aluminum fins (0.4mm thick) make the body of the Macho Zero (spaced 3.1mm from each other).
From the side it's easy to see why the design of the fins increases airflow and holds air between the fins (and also to see that there's zero interference with memory modules).
Although the HR-22 featured eight 6mm heatpipes the Macho Zero comes with six 6mm ones which of course start from the base of the CPU Cooler and through all of its fins.
Once again Thermalright has given their base of their cooler a nice mirror like finish.
You should be able to pick the fan duct of your choice when purchasing the Macho Zero but for our test we used the 140mm version like we did with the HR-22.
