Your gonna be hard pressed to probably find a heatsink that'll work there being in that close of quarters. Gonna wanna measure width of the zalman to compare to others to see.

Thermalright 120 may fit as the Ninja may or even the Sunbeam Tuniq.

I will measure for sure & thanks.

I just talked with a friend at NCIX and he talked with one of the techs who said it wouldn't interfere with performance.

Sorry but I can clearly see that the heat sink wouldn't and can not possibly do the job it is intended to do situated in such a way.

I don't build computers for a living... I wouldn't want that guy working on my system.

He might be thinking sure it would work installed like that but he does think the way we enthusiasts do.. In our minds everything has to be installed to operate the most efficiently as possible.

Note.
Lian Li should have their asses kicked for this screw up. With a case as large as this there is no reason why the motherboard has to be mounted that low.

I can't believe somebody who would call themselves a "tech" would say that..... I'll see if I can set up a little mock-up for you tonight and post some #s by tomorrow.

How much pressure is the heatsink actually applying to the case?

It's already been mentioned, but it's worth mentioning again that you can always just dremel off 1/8 - 1/4" of the offending fin. I doubt that would have much of an effect on temps, and is something that a lot of folks need to do in order to make heatsinks fit properly.

Here's a picture that I found of someone else's dealings with this shit.

Wilson, I have tried to make it work there is no way it will fit properly and there is no way I am going to start cutting this case. I talked with my friend at NCIX who said he will take it back so I will be looking into another HS I am thinking this HS.
http://www.ncix.com/products/index.p...facture=Scythe

I won't buy another HS sink unless I know it will fit. Truthfully I didn't think for one second I would have any issues with installing any heat sink into this huge case.

I am sooo Pissed!

Hey I thought about that being it is smaller. Are you referring to this one and if so will it fit on a C2D?

My System Specs

Ok I ran a quick and dirty mock-up just to confirm what lack of airflow can/will do.

I used my test bed, so keep in mind that it's an open case. Both this case and yours have external fans directed at the heatsink, but the AC 7 Pro probably gets more benefit from the fan because the fins run all the way through and in the direction of the external fan airflow. Your temp difference will probably be higher due to the fact that the external fan is only affecting the fins it blows directly on.

All I did to simulate the conditions in your case with the heatsink mounted that way was to use a piece of cardboard to restrict airflow on the "exhaust" side of the heatsink. I'm not convinced that metal would make any difference, but if it did, it might actually help in wicking away some heat where the cardboard would retain it. (acts like a giant heatsink itself).

This is a pic from the side (top of carboard was pushed closer during testing). You can see that there is at least 1" of space between the heatsink and the cardboard restriction. It looks like yours is closer than that, so I'd expect much more dramatic results from the restriction on your setup.

Ok, here's the results after 10 minutes (you can see when the restriction was inserted). Even when the cards are stacked to keep the temps down (better style of fins for using the large external fan, restriction further away allowing better airflow, and open case allowing better general overall airflow) there is still an immediate 3+ C difference in temp which would probably continue to increase over a longer testing period, under conditions more closely matched to yours.
If I had to hazard an educated guess... it'd be at least a 5+ C difference to your system with that kind of restriction, and I'd guess it'd be a lot closer to 10 C than 5.

Default no its just the stock amd 64 opteron heatsink

Its got 4 copper heatpipes and seems to be very well designed for socket 939 cpus...doubt its anygood for 775. The one i have works great <42oc load even with 33oc room temps. theres a picture of one in r0c0's parting out thread in buy/sell. I thought they might be on ebay but no luck. maybe amd will sell them? just a thought if you dont want to MOD anything.
