Member Reviews: Prolimatech Megahalems Rev B. Intel CPU Heatsink (LGA 775 / 1156 / 1366) (AM2** / AM2+** / AM3**)

I bought this over a year ago for my Q6600, so i could go from 3.2Ghz to 4Ghz. Well the Q6600 needed 1.6V+ for the 4Ghz so i settled for 3.8Ghz. This monster did a great job of keeping it cool. I had a Zalman cooler for it originally. It got up to 77-82C under load at just 3.2Ghz on my Q6600. With this beast it barely went over 50C under load with a Ambient of 30C. Now i have a Q9550 E0 at 4.3Ghz and 1.43V and she stays under 60C with this Cooler. Can't be happier. Also, i got a buddy with a QX9650 and this Cooler, he is rocking 4.6Ghz and 1.5V and only hitting 66C. Bottom line, if you don't want to pay $75-$130 for a Noctua, only to gain 1-4C drops in temp or a WC Setup, then get...

After excitedly replacing my 212+ with this beastly piece of heatsink, I was easily able o push the limits of my 2500K much further. However, when pushing the limits of air cooling voltages it falls a little flat. Even with low ambients and a goot seat atop my 2500k's IHS, pushing the air cooling voltage limits isnt quite happening. Pushing 95C in a 22C ambient with 1.48v under IBT keeps me from pushing her all the way into voltage territory where I might be able to stabilize another step in multiplier. Still for being able to cool the 2500K at 5ghz, it deserves it props.

I purchased this CPU cooler when my old one wasn't performing well with my overclocks. Needless to say this solved my problems. The cooler was fairly easy to install, I didn't run into any issues. This cooler holds my cpu at around 32*C idle and 55 load, which is really great for only having one 1000 rpm 120x38mm fan attached. This cooler did not come with clips for 38mm fans so I attached mine with zip ties, which works just fine. I would recommend this to anyone who is looking for one of the best performing and best looking cooler on the market.

I've owned several aftermarket tower style coolers, and this is the best of the bunch. Running an overclocked Thuban it used to load at 50 degrees Celsius on a Cooler Master Hyper N520, but with the mega it loads at 38. I ordered the AM2+/AM3 mount from Frozencpu.com, they had the best price at the time. It's a great cooler for Intel but bare in mind the additional cost if you're on AM3, which honestly for the price you might be able to find something comparable for the same, if not cheaper.

Just a short review on this one more so to give an idea of performance. Firstly I'll get the cons out the way. It is big and heavy. I doubt it will do damage to the mobo, but it was a surprise to me how heavy it was. As for the size, it is about 12-13cm tall so make sure you have enough space in your case before buying. Now with that out the way let's get to the good stuff Ambient Temp - 20 degrees CPU idle Temp - 25-26 degrees CPU load Temp (Prime 95) - 52 degrees CPU highest Temp that I've recorded since purchase - 55 degrees In my opinion these temps are spot on for my i7 running at 4.5Ghz with 1.214v. Being an air cooler it is silent, and the cooler itself also features some fan...
