Common LGA-1366 Cooling Myths Busted

With the entry of the Core i7 Bloomfield series processors this September thru October, the computing world will witness the entry of a new motherboard processor socket, the 1366-pin Land Grid Array (LGA-1366). FrostyTech demystified the new socket in respect to the way coolers are to be designed to be compatible with it, which will have implications on a vast segment of DIY consumers since LGA-1366 is meant to be a high-performance flagship computing platform. There are two key factors at play:
  • The layout and cooler-retention mechanism of the socket
  • The area of contact between the cooler and the processor's integrated heatspreader (IHS).

Firstly, your LGA 775 cooler won't fit on the LGA 1366, reason being that for the LGA 775, the mount-holes on the motherboards for retention pins / bolt-through kits used to be 72 mm apart. For the LGA 1366 they are 80 mm apart. It wouldn't be wise improvising an adapter to make it work either, since the heatsink's contact area with the IHS will be reduced. For the LGA 775 it is 28.5 sq. mm while it's 32.0 x 35.0 mm (yes, it's rectangular).

Speaking of the cooler retention mechanism, some coolers could use spring-tensioned machine screws to attach the heatsink to a metal backing plate. Intel's stock cooler is found to use standard through-PCB plastic push-pin mounting brackets. There won't be a retention cage (of the sort found on the older Socket 478 motherboards).Source: FrostyTech, image courtesy: Bit-Tech.net

can't afford intel, but will say goodbye to amd if they dont have something as good as you can't afford? Ok...

As for me, I do NOT see this chip in my near future like some of the richer enthusiasts around here. If anything, when this comes out, I'll be buying up the 775 chips as their prices go down.

I just want to say this and i may be totally wrong so if I am please correct me

It looks like they could have easily made it compatible with previous coolers, and by doing it differently - I suspect a backhander by the cooling companies.

Ha! Me too -- I've always wanted to try out a Core just to see how high I can clock it, but I hate to buy one now, knowing that AMD needs all the help it can get (due to Intel's anti-competitive practices).

read the source...it says the stockers do , but the cooler thay used had screws and a backer plate!

Stock cooler (that's an ES, final product could differ):

This is like AMDs news about a rectangular socket for their new parts. Looks like Intel may have done the same thing perhaps?

Is it just the CPU and socket thats just recangular? Or are the cooler mounts in a rectangular spacing too?

I dont know where you've been latly but AMD will ALWAYS be behind INTEL.. the only reason that AMD is in the game is that it would be a monopoly... and they own ATI, they just released the 4870X2... and to me.. thats the best fukn card on the planet...s0n!

Well this is just completely wrong. AMD has been ahead of Intel before, and when they where they where p00ning the crap outa Intel.

Also, that stock cooler looks ghey.

AMD had the first IMC, and the athlon 64 (939) was ahead of intel for a long time.

Intel have now changed the socket to go with an IMC, as well as triple channel ram - besides 775 was old hat, people were getting used to it :P

Yes.
In lamens terms, as newer processors increase in performance, and compute more input/output operations per second, new processors are getting more and more powerful and eventually 'outgrow' their socket. The processor manufacturer releases new socket types with more pins so as not to artificially limit their new processors' potential performance.
It's to do with how fast or how much the processor can communicate to/with the rest of the system (ie motherboard, RAM etc).

sometime i wonder if Intel is ever gonna stop copying amd in everything.. amd only built the shitty phenomenon so that Intel would copy it and get a beating for it.. unfortunatly it never happened, but watch and see what happens to nehalem as amd has shanghai and deneb to counter.. nehalem has problems which they are hiding from us but cannot from amd. which is why shanghai is being rushed in b4 Intel fixes it lol

i congratulate you on having a useless, uninformative post full of bias and fiction.

AMD built the phenom... and it was flawed. they're only getting to their original goal now with the release of the SB750 on the newest boards. If you think nehalem has more problems than the phenom... you're in for a surprise.

Don't forget that the IMC needs quite a few more pins than an old school FSB setup.

I guess you wern't around when the Athlon XP's were raping the Pentium 4's good and hard.
