The original Megahalems have been on the market for some time but today we will be take a look at the Rev B of the cooler. There are a few minor difference that set the first cooler apart from the second. One would be the shiny stain-less top fin and the addition of socket 1156 mounting hardware. The tower style cooler when looked at a glance would remind you of a typical tower cooler. But the center divide which is a narrow lane of open space is how it differs from the masses. Honestly, I am to anxious to get into the testing phase of this cooler just to see how well it really performs.
