Prolimatech Megahalems Rev B. Intel CPU Heatsink (LGA 775 / 1156 / 1366) (AM2** / AM2+** / AM3**) Hot Item!!

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 available in options below!

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

air close to water

My Asus P6T Delux V2 loves the Prolimatech Megahalems. I have it oriented sideways (top to bottom) rather than vertical (back to front) My Gelid 120mm fan is mounted on the bottom of the cooler and blows up through it. I have 12G of ram and no problems with space. My temps are conservatively about 15 degrees (or less depending on how i have me fans set) Celsius above ambient at idle. That''s a good 5+ degrees C less than my old Zalman CPNS9500. Your i7 chip is rectangular and you want to orient this cooler so that the most number of cooling pipes cross the cores. If you do that, and maybe use just a tiny bit of extra Arctic Silver 5, you will temps that rival basic water cooling! You can''t beat that!

Undeniable

Best performance possible for the money. You could even spend double and still under preform. I had a corsair H50. This bested it by 10C idle and 30c load.

This thing is awesome

Under load with prime95 this thing keeps my core-i5 cooler than the stock intel heatsink idle. My only complaint is this thing is huge. I have a full tower case and i had to cut part of the side fan off to get this thing to fit.

Fits Asus P6T Deluxe V2 perfect

Shaved about 5c off idle temps so far - below my old Zalman 9500. It does not block any part of my RAM and I have all slots filled and have 12G total. I have normal size RAM blocks - no cooling fins. There is easily room for a "push pull" dual fan set-up. So far, I like this cooler a lot.

Beast.

This heatsink is a beast! Temperatures dropped from ~40-50C to ~20C. Highest i''ve seen temps hit is 23C. Normally idles for 18C. Mounting system is awesome, although when you''re screwing in the two spring-loaded screws, the heatsink may slip and slide a lot on top of the CPU. Not a big deal though, just be careful. Tight fit in an Antec 300 case. Using this with AS5. Two fans, push-pull configuration expelling air towards the top of the case. Oh that''s another thing, be sure to use it in a vertical orientation. Review sites have found this is the best way to orient the heatsink, although, it might kill airflow around your DIMMs.
