Prolimatech Megahalems

Prolimatech is a newcomer in the enthusiast market, and like ThermoLab it aims to grab our attention with a very high end CPU cooler product. Dubbed the Megahalems it’s their first mainstream product (some slides reveal more products in the pipe-lines), it features 6 large diameter heat pipes and an insane amount of aluminum fins.

Prolimatech Megahalems
- Intel S775 / S1366
- Heatsink : 788 gram
- ~$65

Prolimatech’s about page goes straight to the point, the Megahalems is designed for high end computer enthusiasts, it comes at a very high price and inside the box you only find the essentials: thermal paste, mounting gear, fan clips, short installation manual.

The heatink is made up of 6 large diameter heat pipes which are joined in a copper base, they go up at each side into two separate columns of closely packed aluminum fins. The production quality is very high. The whole is nickel plated for a cleaner look.

The copper base shows very dim traces of machine lapping, when you visit the Prolimatech website you are greeted with a message regarding their heatsink’s base:

Prolimatech does not condone any type of lapping done to the CPU or to heatsink base. Every Prolimatech's heatsink base is designed on a pin-point scale of how the base is to be flat and/or curved where it's needed to be. We have programed our machines to machine the surface in a very calculated way. Any after-manufacture lapping or modding done to the base will alter the design, hence negating its performance factor as well as its warranty.

While the base in our pictures doesn’t feature a mirror polish, it’s not required, as long as it is adequately flat and doesn’t show large imperfections it will do it's job: transfer heat.



Since this is an Intel only heatsink Prolimatech decided to make a mounting system based on… AMD’s two point mounting method. Instead of opting for the 4 point installation of S775/S1366 with 4 mounting screw, you have to first (without tools) install two aluminum brackets at each side of the CPU, you have place the heatsink on the CPU and then place a third aluminum bracket in the center that holds the Megahalems in place. Of the 23 heatsinks tested today this is the only one where we had to modify the mounting gear a bit to make it fit, at one side of the CPU socket the aluminum bracket was touching the caps, a bit of grinding and cutting later it could fit.

The Ultra-120 from Thermalright also uses a two point installation on AMD’s S939/AM2 and you could turn the HSF slightly left/right after it was mounted, the Prolimatech method has a few extra holes in the base (at the top) and knobs on the aluminum mounting bracket to prevent this from happening. Overall the installation is quite straight forward and doesn’t take too much time (as long as everything fits ok with your motherboard)



Prolimatech includes one set of fan mounting clips, which only works with 120x120x25mm fans. For the $60+ asking price a second pair would have been much appreciated. They do sell them separately for $2~4; also available are clips for 120x120x38mm fans. We mounted our Delta 3200rpm 38mm fan by borrowing the clips from ThermoLab BARAM;


Onto the performance results, the Megahalems’ aim is quite clear, be the best at this price point, the Thermolab BARAM, Xigmatek Thor’s Hammer and Thermalright Ultra-120 Extreme make for some excellent comparison material:



We used our 3 reference fans on the 4 heatsinks, starting with low noise results first, the NCB@Low is an excellent partner for the Megahalems, it’s noticeable better here than the competition, in fact, it beats all other heatsinks (when equipped with the NCB@Low) out there, except one IFX-14 (49.5°C). That’s quite an achievement, as this means the Megahalems is better then Scythe low-noise tower cooler line-up. (Ninja CU checks in at 54.5°C). Moving on the Global @ High which is still quite low noise considering the upcoming fan solutions. Here the Megahalems comes in 2nd a few degrees after the Ultra-120 Extreme.

Onto the big boys, 115CFM Titan first. 2nd place, 1.5°C after the TRUE. Delta 3200rpm: 1st place, 0.5°C lead..

Overall we can conclude that these high end heatsinks are extremely well matched, the Prolimatech sticks out at the low noise end, delivering CPU temps noticeably lower than the competition. With mid-range CFM fans the differences are smaller and the TRUE catches up. With higher noise CFM fans the CPU temperature is quite similar, taking into account a 1-3°C inaccuracy and you can see there’s no clear winner amongst thing group.

In summary here are the strong/weak points of the Prolimatech Megahalems:



+ Excellent Performance/Noise Level With All Fans!
+ Solid Installation

- Price (pay more for extra/different fan clips!)
- Possible mounting bracket compatibility issues
