I've heard that the shim around the GPU sits a little higher and could cause some problems with aftermarket waterblocks. You guys heard this?
What would be some remedies for this problem? I've heard a coldplate might work, but I've never used one before. Someone linked a 1/4" block of copper that could be used?

or you can wait until the card is released and see what h2o products come out?

The MCW60's base is set lower. That may fit within the shim.

Every ATi GPU is lower than the shim around it. It's really nothing new.
The extruded base of Swiftech MCW60 is 28mm wide and is barely enough to cover R600 completely as the die is 27mm from corner to corner (opposite corners).

Just remove the shim if need be. All the ones I have removed were barely stickied down anyway. The stuff they used to hold the shim in place looked to me to be more like two-sided tape than anything else. I hear Monday is the big day. Several forums are touting the 14th as the R600's release date. And if the price is even close to what I have read it to be, I hope the release is big enough to handle the onslaught. I have my $400 ready. HEHE (I wished)

do the old dd maze 5 or aquaxteme mp-01 support HD2900XT?

Eddy. any release date for a block for the r600 from you ?
Whenever eddy releases his, I'm going to be all over it.
I want to get some quality cooling for this beast.

I have to ask why you want one to begin with? Those benchmarks were pretty lousy. Although the 2900 XT was decent, surpassing the 8800 GTS, the 2900 XTX was lousy, and apparently those were release drivers.
Are they cheap or are some new benchmarks out?:confused:

Good news about the MCW60. So it seems like it will fit with no further adjustments. Time to pick up one of those, I guess.

I was thinking the same thing. 640MB GTS, OC'd on water FTW!!
X2900XT overhyped, overly hot and overdue. Why would you want one??

If the MCW60 fits, I'm assuming the D-Tek GFX's will fit as well?

Because it's not voltage-limited like G80 and can be overclocked a helluva lot more with the right cooling.
Watercooling is useless on G80 w/o a hard volt mod because you'll hit the voltage wall long before temps get too high, and I don't really care to toss away a warranty on a 400$ product.

I'm at least testing it tonight ot see if it will fit. I have a MCW60 brand new waiting to fit to my newly 2900XT.
From the looks of it, it shouldn't be a problem with the shim since its has room to play with since its offset. Well see though but I'll make sure I get back to you guys on this. When I actually have the setup assembled and computer running.

Have to agree, software controlled voltage is really nice let alone that these seem to OC very nicely without any voltage adjustments too.

Thanks.

Ya the only thing is I might not have enough ram sinks with everything I have to cover from the 16 ram modules to the mofets on the card.
deathman20
05-17-2007, 07:44 PM
IT FITS!!! perfectly no need to remove shim. As well im amazed that the ram chips and mofets aren't even attached to the main heatsink. Its just the holding plate to keep the heatsink in place mainly on top of the GPU. Absolutely amazing.
Xion X2
05-17-2007, 10:11 PM
Awesome. What kind of temps are you getting?
So you're saying the original heat-sink wasn't making direct contact with the mosfets and RAM?
I wish I knew for certain whether or not the Maze4/5 would fit on this. IMO, they have a better look than the MCW60.
jabski
05-17-2007, 10:29 PM
yeah deathman stick some results up for us please :)
deathman20
05-18-2007, 04:28 AM
I will im still in the building phase and hope to have completion and tests today.
As well yes I'm saying the main heatsink that contacts the core has zero contact with anything but maybe the plastic casing and the GPU. It has zero contact with the black plating on the back and the red mounting plats on the front.
Right not I have it on there, weather stupid or not since I don't have enough ram sinks to cover all the ram and the mofets I just took the plastic housing and the main sinks off.
Xion X2
05-18-2007, 07:31 AM
Hmm. It's tempting to not even bother with the extra ramsinks, then, but I would think they would still help on a heavy overclock.
When you get a chance, could you bench the card both at stock and with an overclock and feel over the areas of the card where the RAM/mosfets are? This might give us an idea of whether the extra sinks are needed or not.

Well initial ramp up.
Inital Cold Boot
3.0Ghz on CPU (Heatsink ~31-32C Idle) (Water ~33-34C Idle)
GPU Stock (Heatsink ~49-53C Idle) (Water ~32-33C Idle)
Other Temp Sensor (Heatsink ~50-53 Idle) (Water 37-38C Idle)
Mentioning the other temp sensor also take to note I just removed the GPU heatsink. I left the fan attached but not plugged in and the main base for cooling the ram and mofets.
Running my first 3D Mark 06 tests here just to get a little idea on temperature but I can tell you right now its looking good. Sure its only a few min long but at least it can give me an ~ to what really the GPU will be under full load for hours. I don't know about you guys but these first tests is VARY promising.
Edit:
Load where it maxed out in 06 Test
3.0Ghz on CPU (Heatsink ~38-40C Load) (Water ~36-38C Load)
GPU Stock (Heatsink ~76-77C Idle) (Water ~39-40C Idle)
Other Temp Sensor (Heatsink ~71-73 Idle) (Water 42-44C Idle)
Now mind you this is just a quick 06 run. Temp will go up. But I'd say not bad at all. Added note the plates on the card are still cool to the touch. Mind you I do have a 120mm fan blowing over that area as well.

I'm using Swiftechs 3 120mm rads. Its in a loop with the CPU which is first, and on that note I just noticed that my CPU temps suck which means bad mount. Defiantly not a cool thing since it took 4 hours to get it into the case. I'll have to figure out what I can do to remount it without taking the mobo out because if that happens well :banana::banana::banana::banana: im screwed for a while then.

Yeah, it does; I'm just worried about pricing. Their stuff is expensive.
Full-cover block for G80 goes for $139.95 on their site.

Like the nice temp difference? Mine is still in the mid 40's even on a 900/1000 clock.

Someone had mentioned something about a hold-down bracket on the Maze's that would make it incompatible?
Great news if you're able to get it working. Aren't the Maze5's basically identical except for the insides?

Um I got it to 45C so far. Oh ya forgot to mention at 900/1000.

Damn! Thats amazing temps compared to the 85degC it was getting on load with the stock cooler.

Can you take a picture of the back. I wanna see what the mounting holes look like. If you can give measurements even better.
deathman20
05-20-2007, 06:09 AM
For mounting im using the GeForce mounting kit from the swiftech MCW60. Have to give me a bit for measuring it though since I don't have a good measuring device right now. I'll take more pictures as soon as I finishing putting it back togeather. I was getting really bad CPU temps so I decided to rip the loop apart and fix a few mistakes.
With me on stock cooler it topped around 75-80C so its a 30-35C drop which is amazing by itself. Really im expecting it to settle around 50C load temps either way thats a massive improvement.

no good pics of the back but if you are talking about the black metal haetspreader , i removed it and don't plan on reinstalling it.
i tried ramsinks at first but my oc didn't improve so i am currently running naked, so far 1020 is passing will edge up over the next few sessions.
my core is comfortable with 870 for all benches but scores don't improve over 850. tried 880 but 06 and 03 crashed. whenever ati tool is done it should go well into the 900s.
some pics:
installed on rd600, test fit.

I couldn't tell, but did the whole core area get covered? It looked kinda like the edges were left untouched. I could be wrong.
jimmyz

the very corners do stick out past the block by a mm or so about the same as the stock cooler. if you look at a pic of a r600 the shim has releifs for the core

I don't think so mine gets fully covered by the waterblock. And my temps show it greatly. I've yet to really go above 45C on the GPU on high OC's. Still working it out whats causing it to drop out after a while but surely some voltage will solve that issue ;)
