Prolimatech Megahalem Review


Back in 2008 a group of very experienced engineers decided their current employer wasn't listen to them enough. They were so full of ideas and designs it was starting to get annoying making products that all look the same. Enough was enough, they packed their bags, emptied their office drawers and left, taking their ideas and designs with them. If ever Thermalright made a bad decision it had to letting these guys go.

The Prolimatech brand made waves with its first release not only looking better but outperforming what had been considered for so long to be the best cooler on the planet, the Thermalright T.R.U.E. Going from strength to strength we are happy to finally have our hands on some Prolimatech goodness, namely a Megahalem. A name that every enthusiast and overclocker alike has heard about.

So let's rock on in a shameless fashion and copy & paste some specifications in because I'm too lazy to write them.

- Minimal air resistance between fins allowing best balance between noise and performance in range of 800 1200RPM.

- Heatpipes are lined up in a straight line to prevent air back draft allowing air to easily pass through the heatsink body.

- Wide fins with mathematically calculated thickness to maximize best air-to-surface cooling rate.

- Uniquely designed, easy-to-install socket 775 and 1366 retention mechanism to increase cooling ability.

- Includes easy-to-apply high grade thermal compound, a perfect sidekick to all Prolimatech heatsinks.

Lets head over the page and get the box open!

Initial Impressions

Packaging in the UK doesn't mean as much as it does in the US. Although the US is famed for its obesity epidemic when it comes to PC components it's us in the UK who cant prize ourselves off our PC chair to go to the PC store. Instead we just move the mouse and order online. Maybe that's the reason why Prolimatech kept the box nice and simple in a two tone style like a 1970's advert for the Ford Capri.

Removing the Megahalem from its understated packaging the first thing that grabs your attention is the two separate vertical towers. Unlike other coolers on the market the Megahalem is designed to have the fan blow against both the towers at once rather than a fan on each.

The two towers on the Megahalem and connected by 6x 6mm heatpipes and helps gives the cooler a beefy but somewhat familiar looking base. The heatpipes have been kept inline to allow air to pass over the mathematically spaced fins which I'm told are the perfect thickness to allow for air to surface cooling.

Enough of all this, you've seen it, you like the look of it. So like a good night out in Essex let's head home for some rough testing to see if its worth keeping.

Installation is very simple, once you've done it once. But when first looking at the contents of the box in true manly fashion without reading the destructions it can be a bit daunting. So here with some pictures to beef the page out or to read like a comic is the simple "how to fit your Mega guide".

1: Push the Rivet nut through the correct position on the back plate 775, 1156 1366 from inside to out

2: Push though motherboard and fit the double ended screw nut short thread down

3: Screw aluminium strip adapter down with the screw nuts to create the two bridges.

4: push the mounting plate through the heatsink making sure you locate the 2 pins. 

5: Use the spring loaded screw to secure the heatsink to the 2 supporting bridges. 

6: If yours doesn't look like this, put the Strongbow down and go back to number 1.

When it comes to testing we like to make it relevant, so a 4GHz Intel i7 930 system seems a great place to start. We ran each test 3 times, with fresh thermal paste application each time. Each test was allowed to idle for 30 minutes before a 60 minute prime95 torture test. We chose to use Xigmatek orange bladed fans on the Mega during testing.


The Prolimatech can not keep up with the Noctua but we must remember that the size causes some problems with some configurations. Keeping a 4ghz i7 at 74c with one fan should not be sniffed at. We were quite careful to keep the ambient temperatures as close to 20c as possible yet our tests do suggest that when using a single fan a 'push' configuration works best.

Lets move on to the conclusion and wrap this up.

The conclusion here will be short and sweet, considering the Megahalem is much smaller than the heatsink we compared it to it performed very well. managing to keep our test system below 75c at all times with 12v fans is brilliant. For those of you looking for something quiet you can also go for the push pull method at 9v for a very healthy 77c.

The heatsink at first does seem like a jigsaw puzzle to fit but is very simple once you have done it a couple times. The mount allows for plenty of pressure without warping the motherboard which helps keep the temperatures down that bit more.

All in all the Prolimatech Megahalem is easy to fit and performs very well at any fan speed. We would recommend buying good quality fans like the Xigmatecs we tested with that provide a good CFM though to get the best out of it.

Because of all these factors the Megahalem has easily earned itself the OC3D Performance award and you could do much worse than head out and buy one of these for your overclocked i7 system.

- easy and efficient mounting system
- twin towers look great in a case
- excellent performance even at 9v

- none

- nothing what so ever
