Prolimatech Megahalems Rev B. Intel CPU Heatsink (LGA 775 / 1156 / 1366) (AM2** / AM2+** / AM3**)
What the vendor shipped was:
Prolimatech Megahalems Rev B. Intel CPU Heatsink (LGA 775 / 1156 / 1366)
And this was even missing one of the brackets shown in the picture.
I did not look for the ** thinking it was just some funny terminology for the socket. Turns out, buried in something called a description way at the bottom of the page was a statement that more hardware was needed to mount to an AM3 motherboard but it did not say what was needed. The seller does not appear to have this hardware. There was no "People who bought this also bought AM2 adapter kit".
I did eventually find the hardware at another vendor by Googling "Prolimatech AM2 Retention Mount Adapter Kit"
This is not to say the cooler is bad, just misleading copy.
My problem was that the stock cooler wasn't nearly good enough even for modest overclocking under high load. The HAF922 case has the nice feature that it provides access to the backside of the mobo near the chip -- it was easy to remove the stock cooler, clean up the thermal compound and proceed with mounting the Megahalem. Just follow the well-diagrammed directions carefully. Of course, I took the precautionary step before purchase of comparing the dimensions of the mobo the mechanical drawing of the Megahalem provided by Prolima on their website, so I could check clearances. No installations issues or problems, just a bit of care to mount the 'strip adapters' in the right direction so that the mounting plate fit. In fact the hardest part of the install, was attaching the 2 pairs (yes, 2 pairs are provided not 1) of fan mounting clips and fans. Bottom line is that my i7-920 is now running at least 30oC cooler than before and all fits well even in the mid-tower.
I did not do as the directions said. I did not apply the thermal paste to both the processor surface and the heatsink base. I wish I had. I may pull it, remove the paste, buy the arctic silver paste and try that. I did the one centered dot method on the processor and a little tiny spec on the heatsink. I should have evenly applied the paste to both surfaces as per the instructions. This was my first build and my only regret so overall I'm very happy.
I did the fans in a push-pull config. My case is set up to push air out the back and pull in from the front so it's pulling the heat off the 12Gb of Dominator RAM that's right next to it, and I mean RIGHT next to it. One of the fans is pushed out 1/8th of an inch because it is resting on the RAM heatsink.
The product arrived on time, had all the parts, the instructions were easy to understand, and it functions properly. I bet it will function even better after I reapply the thermal paste.
If I find myself having to SLI another Quadro FX 4000 I suspect I'll have to go with a liquid type cooling system but for now this is sufficient.
