Prolimatech is a relatively new Taiwanese company founded in 2008. They have possibly the most interesting product line we've ever seen — it consists of only one item! Stranger yet, their only product, the Prolimatech Megahalems CPU cooler, has been making the rounds at several well-known PC enthusiasts sites and getting excellent marks. It's impressive for a new brand.

The Megahalems, up close.

The Megahalems is its name, an obvious play on Nehalem (though why the name is pluralized is a mystery), the codename for Intel's first family of Core i7 processors. If any CPU deserves a "mega" heatsink, its the 125W Core i7's. The Megahalems is another giant aluminum tower heatsink with a six heatpipe design. It is compatible with Intel LGA775/1366 motherboards only and does not ship with a fan.

Feature & Brief
Our Comment
Minimal air resistance between fins allowing best balance between noise and performance in range of 800-1200RPM This is a critical issue. Only testing will tell if they got it right.
Heatpipes are lined up in a straight line to prevent air back draft allowing air to easily pass through the heatsink body It seems logical to stagger heatpipes to maximize their exposure to airflow, but at lower fan speeds it may do more harm than good.
Wide fins with mathematically calculated thickness to maximize best air-to-surface cooling rate The more surface area the better.
Uniquely designed, easy-to-install socket 775 and 1366 retention mechanism to increase cooling ability. The Megahalems is an Intel-only CPU cooler for LGA775/1366.
Easy to apply, high grade thermal compound, a perfect sidekick to all Prolimatech heatsinks To make a proper comparison to other heatsinks our own reference thermal compound will be used.
