Product description

The revised Prolimatech Megahalems Rev B. Intel CPU Heatsink now comes LGA 1156 ready and contains 2 sets of wire fan clips for optimal performance out of the box. Due to the originals very high praise from multiple review sites as well as winning the Editor's Choice Gold Award from [H]ard|OCP Enthusiast this cooler is sure to please. When it comes to air cooling this cooler cannot be beat! This heatsink has been carefully engineered for low to medium speed 120 mm fans producing around 57 CFM - fans in this range are quiet at under 26 dBA - but this heatsink still cools better than the competition! Six heatpipes pull heat up to the fins and away from the CPU. The heatsink ships ready to mount to either Socket LGA 775 or the latest Socket LGA 1366 and LGA 1156! **Sockets AM2, AM2+ and AM3 require optional retention hardware The tower type coolers have been the mainstream in the CPU cooling market for quite some time now, but upon closer inspection you start to notice that designs and engineering can only go so far as they slowly come to a bottleneck. After a while they all start to look the same with performance not worth popping the champaign. This is where Prolimatech comes in. We are here to challenge all possible odds and stray away from the norm. With that focus in mind comes the new Megahalems, tower CPU cooler. Never before seen are the new lows in temperature produced by an intelligent design of low air flow resistance with unmatched performance to boost; perfect for the true overclockers in all of us **PLEASE MEASURE YOUR CASE TO INSURE THIS HEATSINK WILL FIT BEFORE PURCHASING!! WILL NOT ACCEPT RETURNS UNLESS ITEM IS DEFECTIVE!**

Features

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.

Easy to apply, high grade thermal compound, a perfect sidekick to all Prolimatech heatsinks

« One of the best air coolers around. »

I bought this slightly used (was like new essentially) and it works great. My i7-930 is overclocked to 3.78 GHz with Hyper-threading AND turbo-boost on (up to 3.96 GHz) running prime95 for 24 hours stable and max temp was 78 degrees C. Very pleased.

« Excellent performing cooling device! »

This heatsink is awesome. Is really easy to install, but you motherboard have to be unmounted for it to be installed. I put 2 2000rpm fans on it and the temps are very low now.

I have my Core i7 920 @ 3.5GHz and is very cool and stable. This is for sure the best air cooler in the market!

« Works as designed. »

I purchased the Megahalems (B)to cool my new i7-920 on an EVGA X58 SLI motherboard. I'm using two Scythe SY1225SL12M 120mm "Slipstream" Case Fan in push/pull setup. The system runs cool, as advertised. The only problem has been mounting the two fans on the Megahalems once the Megahalems is mounted on the motherboard. The core on the right and the heat-spreader on the left make it impossible to fit the large 120mm fans entirely on the Megahalems, as both fans ride over the top of the large heat sink tower. Other than making mounting a bit tricky, this seems to pose no problem. It certainly doesn't affect cooling much. One feature i particularly like its the two-pin alignment to the heat sink's base. This allows the heat sink to fit tight without wobble, something I always found wrong with the Thermalright Ultima 90 I used in a previous build.

« Its Large and In Charge! »

The Megahalem is an awesome great looking cooler, and I would highly recommend it for the enthusiast or power-user hoping to keep their system cool and quiet. I use this cooler with no CPU fan and it works well with my rig non-overclocked. If you are looking to over-clock (using a CPU fan) this thing would work great also. My rig under load never goes over 35C and my case fans provide enough air flow to keep things cool and quiet.

With my Antec 900 case it fits in there nice, but there is little clearance between the top of the CPU cooler and the side of the case, but that's fine as it works and there is space to get the case sliding lid back on fine.

Here is my rig:
Antec 900 Case
Asus P7P55D motherboard
Core i5 750 Quad-core socket 1156
Megahalem revB CPU cooler
OCZ 4GB memory DDR3-1600 2x2GB CL8
ASUS EN9600GT GeForce 9600 GT 512MB (fanless)
OCZ 450Watt 80+ Power supply with 140mm fan

« Fantastic »

It's big. Almost big enough I gave it a 4 star review, but it works so well I couldn't subtract any points from this. I have an i7-920 on an Intel DX58SO motherboard, and I've got tall Corsair Dominator memory sticks. Because of the tall heatsinks on the Corsair RAM, I had to orient the heatsink in the non-classic direction. (It's blowing air from my video card down towards my power supply, as opposed to blowing from front of case towards back of case.) It didn't seem to affect performance. My idle temps dropped from 50C to 36C (122F to 97F). My fully loaded temps dropped from 77C to 60C (171F to 140F). Highly recommended unless you have a little case or its too packed in there.
