I am building a new system with socket 1156.

Here's what I have so far:
Gigabyte GA-P55m-UD2 Mobo
WD Caviar Blue 640 GB Sata II HDD
Gigabyte GTS 250
Patriot Dual-Channel DDR3 1600 RAM (2x2GB)
Antec Earth-Watts 430w
Antec Six Hundred Case


The only thing I lack is the CPU (and perhaps a CPU cooler---but I don't plan to overclock and I plan on going with an intel OEM cooler.

I'm heavily considering the i7 875k. Even though I'm not planning on over-clocking now, it will perhaps be better in the future, should I need to do so. Also, it's almost the identical price as the i7 860 or i7 870. For some reason, the i7 870 receives some pretty mixed reviews, with a significant number of users complaining about a heat issue. So, I will probably stay away from that CPU. My question, is that, since the 875k comes without a heatsink and fan, is it possible to fit an OEM heatsink designed for the socket 1366 i7 9xx series of processors (like a fan/heatsink from the i7 930, 950, 970, 975 etc) on it?

I'd really appreciate any pointers. Thanks a lot.

I could be wrong on this but I had always thought that the heatsink mounting was the same for 775 / 1156 / 1366.

As far as 775 / 1156 goes, nope. The holes are in different places.

The Cooler Master Hyper 212+ is ~$30 at newegg. Not that expensive, no?

Nope, all 3 are different. 775 to 1366 pushes the pins out about 1mm in each direction

1366 they are set out quite a bit wider still.

I don't understand why you want to install a heatsink designed for the LGA1366 socket on a LGA1156 CPU... Why wouldn't you just get a heatsink designed for the socket you are using? There are some heatsinks that are designed to be usable for all of the different sockets, for example I use the Corsair A70 Heatsink, which has a backplate that can be adjusted for any of the sockets. As far as a stock LGA1366 cooler goes though, I don't think it would be possible to do without modding; the holes are in different places for each of the sockets and therefore wouldn't line up. I recommend just picking up a nice/cheap aftermarket cooler like the coolermaster hyper 212+.

Hope that helps/answers your question. Best of luck

The H70 has a similar arrangement. The same locking plate works with both LGA1156 and LGA1366, but the oblong-shaped pin bushings are reversed depending on which socket you need it to match. They definitely wouldn't interchange, otherwise.
