The 1u server apogee is essentially an apogee bottom and an mcw60 top.

Guess the paste settled in a bit, but this is as good or better than my dd twin blocks on 7950 gx2. Mind you it was severely overvolted, so we'll see what happens soon, in that I will volt mod this one, followed by sli

I decided to use the oem fan and shroud, in that in an sli app, the 80mm fan hanging down would hit the case, and/or not allow any pci cards.

Here is version 2 almost. (I cut the ears off of what you see in the picture)

I know, and I've actually said so before, but not everyone sells the apogee 1u.

surely you can oc the card more than that on a water cooled setup??

I'm curious about this as well...

just to clarify, the 745/1100 is on phase cooling ? WATERCOOLING tests are still to be done yet right ?

no...745/1100 was on water

I am playing with phase, but haven't gotten any further than 745/1200

I got a few E6600 cpu's (B), so I'v been side tracked a bit.

I will get back to w/c tests soon

I have been reading about this block and it gets more interesting as I read about it.

http://i41.photobucket.com/albums/e2...ogge1U-775.gif

Everyone's right, it has the base of the Apogee and the delrin top of the MCW-60 but no mid spacer. It's called the Apogee 1U "Server". We could easily modify the hold down plate to accomodate the spacing for our beloved-and-in-desperate-need-of-good-watercooling G80 GPU's. Trimming 2 MC14 ram sinks to accomodate tubing is no biggy. It is made to cool a CPU so the base plate is 50mmx50mm. A bit larger than the 42mm square of the G80 IHS. It will also accomodate a 50x50mm tec. . .something to possibly consider down the line. Hey I have a Turbo 1K SR why not use the extra power? I think this will cool the hot-as-h3!! GPU on the 8800GTX far better than the regular MCW-60 because of the larger base plate.

Anyone else wanna chime in here?

i really dont think you would see a very big difference. However this is XS, so go for it!

off subject, but this card is at 810/1205 ,but on phase not water at the moment

yes volt mods 1.55/2.15...my lousy phase can't hold it under 0c!!

15,163 in 3dm06...

Assuming that an Apogee 1U or MCW60 with adapter works, can someone tell me whether 16 heatsinks per card would be enough? Or should I order three packs of MC14s per card ? :) Maybe I should buy some super glue too, if the current MC14s are no different from the ones I've been using :)

12 mem chips + the ramdac...and then 4 sets of small chips?

With a fan over them, they don't get too hot..aa in rev 1 where the 80mm fan is used. Hope that helps

That makes 13 if you don't try to cool the little ones

Many thanks, rjw! And have any of those MC14s ever fallen off for you? Mine sometimes do, and once they are off, they are off for good lol :)

So, worst case scenario, with the 8 small chips, 21 heatsinks. Otherwise, its just 13 heatsinks.

Also, it didn't look like you had to trim the heatsinks under the barbs, like I had to do with the 7900GTXes. Am I right?

rjw,

Also, would greatly appreciate if you could kindly confirm that I can use a MCW30 on the Southbridge, as well as one on the Northbridge, as long as I have MCW60s on the vidoe cards? No clearance problems as long as I remove the stock shroud and heatsink?

Many thanks!!

If you mean on the evga 680i mobo?

2 problems...but not that hard to solve

1) the mcw30 on the nb is fine, but on the sb, you will have to insert the screws from the top, because the card as shown with 80mm fan will just clear.

Note: a stock 8800 gtx will not clear, the fan shroud will hit the mcw30 on the sb

That is why I used the 80mm fan setup on the card in slot 1 and for case clearance, I used the rev 2 version w/ modified oem fan shroud on the other card.

BTW...today I changed my nb to sb value (which was at 250) to 300 and guess what?

I hit the F10 key and that was the last time that the board booted up...

rma time I guess

the sb gets really hot, but with mcw 30's on both, they don't even get warm

you wont need that many sinks on the small chips as the surface area on them is to small to attach heavy MC14 onto them.

I have some Vantec sinks which are 13x16 and I halved them to 6.5 x 16mm and they cover all 3 little chips at once ... so I only need 2 of them (cut in half makes 4).

There are 12 memory chips plus a ramdac per card to cool. I used these ramsinks on my FET's. They're 21mmx21mm and one sink covers 2 banks of FETS. One package gets you enough for 2 cards. And of course use the Chomerics Micro Cool Thermattach 412 tape cuz we all know the tape on the MC14 sux monkey tweeters! LOL!

Many thanks, Philly Boy! Again, you came through with another great suggestion.

I love those, I use one each on the vCore mosfets of my 7600GT's. They get quite toasty, the card's vmodded.

Yeah, I will v-mod my cards as well...and they'll have 2 YL D12Sl's blowing almost directly over the ramsinks.
