Now, we will compare the physical differences between the Prolimatech Megahalems Rev. B (pictured on the left) and the Armageddon (on the right).

The Megahalems’ top heatsink fin is embossed and made of stainless steel, but a metal cover is used to cap the Prolimatech Armageddon instead.

There is a minor issue however; the cover starts to rattle occasionally from vibrations caused by fans with higher rotational speeds. It is unlikely you can still hear it over the combined choir coming from within your case; but if the rattling somehow still manages to bother you, tapping on the cover would silence it.


It seems to us that the design team from Prolimatech are avid fans of the Transformer franchise.

The top fin of the Megahalems sports a Transformer-ish embossment; the Armageddon has a toned down (but still Transfomer-ish) design.


While the Megahalems and the Armageddon are pretty similar in height – 158.7mm to 160.3mm, the Armageddon has its fins shifted slightly higher.

Width wise, the Armageddon is a good 14mm wider than the Megahalems.

The Armageddon is slimmer at 50mm, compared to 74mm on the Megahalems.
