AM3 socket specifications, vs 1150 (bolt holes)

[EliteRetard]

Or does anybody happen to know of an adapter bracket available somewhere?
Id like to try an AMD cooler on a new Intel board.

I figure since the AMD mounts with a single spring clip all I need to do is bolt a hook onto the Intel board for it to clip to. I found the Intel specs easy enough, but cant locate good AMD specs.

1150 looks like a 95mm square mounting area with bolt holes in a 75mm square.

Actually here's a pic of the board I'm looking at getting:

And since Intel only offers garbage coolers I'd like to use something like this:

Which fits in the 95x95mm mounting area and at ~65mm tall clears my ~75mm height limit.

You can always zip tie your way around heatsink mounting in unusual conditions with good enough results.

That just sounds like a recipe for trouble. Frankly I would just buy a cheap tower cooler like the Hyper 212 Evo, as it will correctly fit the socket without any messing around and provide much better cooling than the AMD stock cooler.

Eh? In my experience they've been offering pretty nice coolers for years that run virtually silent.

My alternative assumption is that you mean they're not so good for running on overclocked CPUs, at which point I'd have to ask, what did you expect? I'm pretty sure Intel recommends running their CPUs within specs.

The really odd thing is that you then go and imply that the AMD cooler in the image is better despite the fact that the spacing between the heatsink fins is so small that they'll easily and quickly get clogged with dust.

Intel don't make garbage coolers, they make coolers that keep their chips within temp parameters whilst being virtually silent. The fact AMD CPUs are miniature volcanoes and need beefier coolers is no reason to start calling intel out.

Link to a tower cooler that is 95mm x 95mm under 80mm tall.

Intel may have had barely acceptable coolers at one point...but they don't offer anything better than crap 35w low profile coolers now. Its not even funny that they use these for 90w chips which then throttle hard at stock speeds:

I've got plenty of the old acceptable ones laying around...but I have no idea how I would adapt the pegs to fit the new boards. I have the barely acceptable AMD coolers laying around too, and their mounting system has always been superior and will be much easier to adapt.

The AMD cooler in question was designed for 125 watt not 35 watt and should do a much better job keeping a stock 90w Intel chip (4790k) from serious throttling under load.

If there were any other options I wouldn't be trying this...but I've looked and looked and can't find anything else. Noctua has this cute little thing:

Which would be perfect...if it weren't for 35 watt CPUs. Its 95x95x35mm. If they only made one that was ~75mm in height with another 2-3 heatpipes Id go for it.

Not anymore, the stock coolers do not keep their chips within temp parameters, and they don't do it silently, the poor fans are screaming furiously trying to cool these crappy little heatsinks.

 

[Puppies04]

I will admit I only use the stock coolers on pentium and I3 builds, I had to run the stock cooler on my 2500K for a couple of weeks whilst I got my tower cooler replaced as one of the fixings snapped and it ran fine playing BF3 without throttling.

That said if you want a low profile intel cooler why not just buy a low profile intel cooler, plenty to choose from....

[EliteRetard]

*sigh*
I don't want garbage low profile coolers...but I cant fit a 6 ton truck on my CPU either. I can't find any decent mid size cooler that fits the Intel 1150 socket (About 95x95mm and under 80mm) My AMD cooler is closest at 95x95x65mm

So nobody has easy to read dimensions for the AM3 socket, clip/s, and bolt pattern?

 

[Techhog]

This is the strangest thread I've read in quite a while. I'm willing to bet that by "under load" you mean stress tests, and I don't get why anyone would care about stressing a CPU at stock.

Anyway, Noctua NH-L12.

 

[EliteRetard]

Thanks for the suggestion, but 130mm x 150mm is far bigger than 95mm square.

I still haven't found any good AM3 socket specs...but I think 1366 is actually a tad larger than 1150. Trying to decide if I should desecrate a rare Intel heatsink trying to drill new mounting holes:

Only have one...

And this is why I should read the whole post before I reply :awe:

Could you not get something like this? http://www.amazon.co.uk/Akasa-AK-CC...qid=1420622445&sr=8-1&keywords=lga1155+cooler Same basic design as the Intel cooler, but with a larger heatsink and beefier fan. 6.2cm tall, so fits inside your height limit nicely. And it's damn cheap.

As I've been researching it does seem many of the Intel sockets are really close in size and all use the stupid pins. So this one may indeed work for 1150, and its at least a little bigger than the stupid low profile Intel ones. Yet I feel like the AMD cooler with heatpipes is still better ('cause heatpipes)...unless I can find a larger unit (like the one I just posted). I think Id have to try to modify the mounting arms though...

Then there is the even more elusive super deluxe model that Intel made:

But I don't think that would fit (unless I lopped the fins off the top). Always wanted one (and another to mod) but never got my hands on one. These have something like a 40mm phase change vacuum chamber in the center. One of the few acceptable coolers Intel ever made.

Seriously though, if Intel coolers and sockets have been so similar for so long why the hell are there not any decent coolers that fit their socket specs? There's some aftermarket low profile ones, but not a single good mid sized one I can find. It can't be that hard, 80-92mm fan, a few heatpipes and 95mm square fin stack, and keep it under a 2U rack size of 75mm. Boom done, $30...not everybody needs/wants/can fit a $60+ massive tower of death.

Citation needed, and it won't suffice to quote some forum user who probably doesn't know how to install a HSF properly.

Just so we're clear, "throttling hard" means that the CPU has to throttle down its clock speed in order to avoid thermal shutdown. It would basically mean that Intel was supplying a product that is unable to operate to its maximum official specs, and Intel would catch a tonne of bad press from that (probably a lawsuit as well).

"Throttling hard" does not mean "the fan speed goes up".

Look at what Arctic Cooling claims to be the temps of an i7 under load compared to their own:

[DrMrLordX]

OP, if it helps, socket AM3 is physically identical to socket AM2, AM2+, AM3+, FM2, and FM2+ when it comes to HSF mounting. So, if you have the specs you want for one of those socket types (or a board lying around you could measure), then you have the specs you need for AM3.

Yeah 75c is typical in a normal well ventilated case. Which is already enough to throttle top speeds and quickly wear out the MOBO and surrounding components. In a confined case with limited airflow and heavier loads you can easily max 90-100c. I've experienced it and read other reports of it. The low profile Intel heatsinks cant acceptably handle a load on a high end CPU even in the best case. The older 3x size units would offer a notable improvement even in the standard environment and would reduce heat damage and throttling in the worst cases. But they don't offer them for modern CPUs/sockets.

Ideally I'll find something even better than the big old stock coolers, that will actually fit. I do have one special unit that I may modify, it's like a 4x unit with copper fins (and more of them). I think it was rated for the same wattage as the AMD cooler I have with heatpipes...though I don't know which actually cools better. And I still think I'd prefer to make a mount for the AMD rather than mod and possibly ruin the Intel cooler.

Yep, citation needed.

FM2 as well? That I did not know (never used it). I knew AM2 and AM3 were very similar (I know some had a single prong and the others had 3 prongs but I was able to swap coolers between them).

See here is an 1150 layout:

As far as I have been able to determine that's the same as 1155/1156.
And it appears socket 775 may have been 72mm square for the bolts.
Socket 2011 may be 80mm square, same as 1366.

AMD seems to be hard to find. Unless I'm somehow just not seeing it or searching wrong.

 

[DrMrLordX]

Yes, FM2 as well. I just put together an FM2+ system and tore down an AM3 and AM2 system. I had my Big Typhoon VX out at the same time as my nh-d14 (w/ AM3 mounting hardware), and looking at all three boards, it became obvious that all the socket mounting hardware was practically identical. It's all interchangeable.

If I see anything on the goog later I'll let you know. Not sure if your plan will work out, but I do agree that some of those stock AMD HSFs can be very effective. If you could get AM3 HSFs working on 1150, that would be weird but kinda neat.

 

[EliteRetard]

Yep, citation needed.

You already found some yourself. I don't know who tests stock coolers, but if you don't understand that more surface area equals better dissipation then that's your issue. I know the older much larger stock coolers are better than the tiny ~1/3 sized units they now use.

Really none of this is the issue though...I have several larger coolers that I know are better and I want to use them. That is if I can figure out a way to mount them. Or find/buy an acceptable option that will fit the mount and space available.

If I do run into anything "citation" worthy while I'm browsing I might post it for you, but no guarantee.

Yeah, I figure AMD mounting is so simple it could be used on any socket. They just use a bar with a hook on it. So I need to figure out where that bar would be in relation to the bolt holes on an Intel board and then build my own bar with a hook on it. Then I can simply clip on/off heatsinks with the superior AMD setup.

Honestly I have no idea how I'm going to actually do it, I don't have any tools or experience with anything similar that I can recall. I haven't planed anything yet. I figured I could try to mock up the sockets on cardboard first or something and see how they line up before formulating any ideas.

 

[NTMBK]

You don't have any tools or experience, and you're going to try to build a secure mounting system which will hold the cooler firmly enough in place to get a good contact, but not so firmly that you break your damn motherboard? Good luck with that...

Seriously, if you're that worried then just buy one of the slightly larger coolers like the one I linked. £10 on a cooler is better than £50 on a broken motherboard.

 

[mikeymikec]

You already found some yourself.

Specifying a temp significantly below thermal shutdown does not in any way imply whether the CPU is throttling its clock speed in response to rising temps!

Saying that you want to fit an AMD cooler because you think it might cool the CPU better than the stock one is fine. Making initially extremely vague claims about a particular HSF then seemingly confusing your terms when trying to be more specific is not, because other less knowledgeable people might read what you wrote and think that you're stating what is generally considered to be fact.

For example, I have an AMD Ph2 960T. I thought the stock cooler was a bit noisy (as well as the CPU exhibiting higher temps than I'd like), so I replaced it with an Arctic Freezer 13 which has done the trick nicely for me. However, it does not making the stock cooler "garbage", nor is there any CPU throttling going on just because the stock cooler's fan speed went beyond 2000rpm when the CPU was being pushed to its limits at stock frequencies.

+1
Aside from potentially making mistakes like cracking the board when say drilling a hole, I would have thought that static build-up from tool use would also be a problem. That's aside from the probable situation where the most suitable place to drill a hole isn't possible because the board already has circuitry running through that point. I suspect that when a board of that complexity is in production, holes are made before circuitry is embedded, but I could be wrong.

Furthermore, there must be some retail HSFs that are like the AMD ones that the OP is interested in. A quick browse on the Arctic Cooling site shows several. It almost goes without saying that "the bigger the better" (however not strictly/necessarily always true), but I would have thought a decent company producing HSFs would make one that's reasonably compact and is at least a bit better than the stock HSF.

What?

And since when were we talking about AMD CPUs?

You posted a link comparing a "generic stock heatsink" to an aftermarket one. The temp posted was in excess of 75c. Well beyond the thermal limit. For that particular CPU the limit is ~66c:

http://ark.intel.com/products/77780/Intel-Core-i7-4930K-Processor-12M-Cache-up-to-3_90-GHz?q=4930k

It has a TDP of 130 watts. And the stock intel cooler for these new sockets is this:

When the old cooler for example the Core 2 Quads at 95 watt was this:

How the heck can anybody expect these low profile coolers to handle so much heat properly? Even the 1150 CPUs go up to 90 watt, so even for the "high end" mainstream chips the new stock coolers are to small. Fine for the Pentiums and i3's not for performance chips.
