LGA 1366 vs 2011 heatsink mount

I'm not sure but I think the 1366 coolers will fit 2011 BUT it needs an adapter because of some difference. I recall this because noctua was shipping adapters for its coolers free of charge.

A note about your last sentence, smaller lithography doesn't mean less heat. Power consumption stays roughly constant as they chase higher performance. Actually the newer Intel high-end chips like i7-39xx have 130W TDP compared to 105W with the Q6600. Still any decent after market cooler shouldn't have problems if you can get it installed.

What pnjunction is referring to is this and this. See the italicised texts.

The former was specific to Noctua's older HSFs, and thus allowed customers to take photos of their product/etc. and get a mounting kit that was compatible with LGA1155/1156 or LGA1366. The latter was specific to most of Noctua's current HSF line, allowing customers to do the same and get a mounting kit that was compatible with LGA2011.

Mounting-hole-wise (and I'm talking JUST THE MOUNTING HOLES): LGA775, LGA1155/LGA1156, and LGA1366 are all different. The spacing on the holes is increased slightly or adjusted slightly.

I cannot find specifications for the mounting holes on Socket R (LGA2011), nor can I find any hard evidence that LGA1366 mounting holes are different OR THE SAME as LGA2011. I can find some idiotic forum post online from some random Internet jhonka claiming they're the same, but that isn't definitive (for me anyway).

Furthermore, as proven by the 2nd Noctua product I linked, even if the mounting holes ARE compatible, there are added complexities given the "bracket" that surrounds LGA2011 sockets. This is why Noctua came up with a different mounting bracket kit for LGA2011. To see what I'm talking about, click the link, then choose to download the Installation Manual. Once you see pictures of the example motherboard you'll understand.

This "bracketing" problem has also plagued other processor models, such as the Xeon 5500, which is effectively LGA1366 but does not work with some HSFs -- BUT NOT BECAUSE OF THE MOUNTING HOLES. See here for what I mean. It's all due to surrounding metal/brackets/plating that causes issues. I imagine the same issue applies to LGA2011.

So, to summarise all of this hubbub:

You will need to Email Thermaltake and ask them if the V8 heatsink is compatible with LGA2011. There is no other way around it. You can't base compatibility on mounting hole locations -- I've just proven that. Mail them and let us know the results, that way others on the Internet with V8 HSFs will have something to refer to.

on the topic of the xeon 5500's if one were used in a lga1366 socket is there any issue so long as the mobo supports it?

The Xeon 5600 and 5500 are LGA1366. See chart on the right-hand side of the page. So yes, as long as the motherboard guarantees full compatibility with Xeon 5500/5600 processors, then it should work fine. You would need to verify with the motherboard manufacturer first.

I guess its not worth the hassle of trying... heatsinks arent that expensive in the grand scheme of things.

GO LEAFS GO!

Yep, true that. But this is why I've exclusively bought Noctua HSFs for the past few years now. I know that if a new socket type comes out and my HSF can't mount it, Noctua can send me the proper kit that will work with it. Their HSFs are expensive (usually US$50-60), but easily worth it. And their bolt-through kits are superb -- they're server-grade (Supermicro systems use something very similar). No more of those bullshit plastic pegs that break off or bend after 2 uses.

ok thats what I thought
so its just a case of xeon intended mobos having altered mounting

Note for readers: this comment of mine is replying specifically to DarkLogix and is not relevant to the question about LGA1366 vs. LGA2011. See further up if you wish to know that answer.

thanks

sorry for the OT tangent, now back to your regularly scheduled topic.

For what it's worth, I have read that the Coolermaster Hyper 212 Plus HSF has a free LGA2011 upgrade kit (by mail) or the upgrade kit cost ~$5 or so:

BTW, I thought you were a Apple Mac user,......

What are you doing eyeing an Intel Sandy Bridge-E,.....?

Just kidding

Also note there is a shortage of Core i7 3930K Sandy Bridge-E processors so unless you have an in, you'll have to get in line and wait. It's been very dry for a long time.

I have NH-D14 I asked them If I were to need a socket 2011 hold down hardware how much would it be. They offered it to free of charge with shipping. They are the only company i will ever use for my fans and cooling needs.
