I'm considering moving to Haswell from Nehalem by just getting a new mobo and CPU, but I'm not sure if I can keep my current heatsink.

Can an LGA 1156 heatsink be mounted on to an LGA 1150 motherboard?

Edit: I just read 1156 heatsinks fit 1155 motherboards, so I guess the question is also can I go from 1155 to 1150?

What's the heatsink in question here? – happy_soil Oct 25 '13 at 23:26
    
@happy_soil I've had it so long that had to look it up on my Newegg order history, and wow! It's actually this LGA775 Scythe SCINF-1000, with an adapter to LGA 1156 also by Scythe. – Louis Oct 25 '13 at 23:30
    
@Louis - It should indeed work. The best people to answer it though is the manufacture. – Ramhound Oct 25 '13 at 23:34
    
@Ramhound Okay, so the mounts are generally unchanged for the past few years? That would be great news. – Louis Oct 25 '13 at 23:39

@Louis - 1155 is Ivy Bridge my Heatsink was a Ivy Bridge heatsink its installed on a Hawell motherboard. Be sure you post an answer with supporting documentation you can take the credit :-) – Ramhound Oct 25 '13 at 23:44

While I can't find an authoritative reference (ie. from manufacturers), there is a definitive "yes" around the internet.

There are many posts on many forums confirming that 1156/1155/1150 are compatible. Examples at: overclock.net, Tom's Hardware, guru3d.

What I noticed myself when Haswell first came out: existing coolers (such as the Noctua NH-D14, as an example) had their specification details updated to include 1150, but they're still the same cooler.

And, if you accept an unreferenced statement on Wikipedia as a reference :o, the socket 1150 entry says:

Cooling systems for LGA 1155 and LGA 1156 sockets are compatible with LGA 1150, due to them having the same distance of 75 mm between each screw hole.
