I'm currently thinking about putting a fairly nice machine together with a core i7 930 on a Gigabyte x58a-ud3r mobo. I am a bit concerned about heatsinks, since I do intend to overclock it, but I have seen situations where some larger heatsinks start to obscure and even block memory slots. Currently I'm thinking about the Xigmatek Dark Knight and the Cooler Master V8, but I would be open to suggestions of other heatsinks as long as they'll do the job under load as I get up closer to the 4Ghz range and not block ram slots close to the cpu. As far as cases go, I'm looking at a Lian Li PC-K62, as it appears to be wide enough for these coolers to fit. To be a bit more specific as to my concerns, the motherboard I'm looking at has the lga1366 silkscreened area slightly closer to the ram slots than some other comparable boards, though the Asus board with a comparable feature set (P6X58D) is $100 more expensive, so I want to be sure of which heatsinks will not prevent the use of my memory slots on this board, so that I know whether or not it is feasible to go with this board and overclock up to around 4Ghz.
Thanks JohnnyLucky, those are some great articles. I think I had missed the first one especially because I was looking specifically for lga1366, but you're absolutely right that those apply very well. I continue to be open to advice, if anyone else has anything they'd like to say.
The Cogage looks interesting. Reviewers seem to like it. I couldn't find the test where it got put head to head with the Mugen, which is the heatsink I've been looking at since JohnnyLucky posted those reviews. Anyone have a link?
I like the Asus over the Gigabyte .... though with the Rampage II Extreme now having been "unveiled", it's no longer my top choice board.
As to the Heatsinks......I have seen a recent test which showed the latest Noctua take the perofrmance crown but it's 3 pound weight scared me off. So for performance and ease of installation, the Prolimatech Megahalems is my current fav.
Here's what I'm putting in new builds Mega w/ IC Diamond TIM and twin Scythe PWMfans (make sure ya MoBo can handle the fan wattage). ($65 for the HS, $7 for TIM, $11 each for two PWM fans and $7 for a Y cable splitter). Skip the 2nd fan and splitter if you are not going over 3.6 Ghz or so.
So, I wanted to select a best answer because I felt JohnnyLucky really did provide a best answer of those that were given, especially since his reviews really did give me some of the important metrics for me that I looked at. That said, I do like the idea of a prolimatech with a couple of fans in push/pull but it does seem that when only going up to 3.8-4.0 Ghz, the Scythe Mugen Rev B would actually be a bit better on my wallet. In response to the comment about the cogage, I am impressed by it a bit, though it's not on Newegg, and while that shouldn't matter in terms of the performance of the device or my choice of what to build, it is a minor inconvenience when trying to put together a list of parts. I might look into the cogage a bit more, but in the $40 dollar price range, the Mugen has few rivals for what it does. Also, I managed to find a picure of a build where someone fit some G.Skill Ripjaws under a Mugen on the board I'm looking at, or a very similar one, so I think that will work, even thought it might hang over the ram a bit.
Thanks JackNaylor for the listings of TIM. I'm sort of an old fanboy of Arctic Silver, and given it's performance in those tables generally being within a tenth of a degree of best, it looks like if I go with it, I won't have gone wrong, though I am a bit impressed that the other companies have excellent competitor products to it.
