After a member of another forum suggested using aftermarket cooling to reduce the amount of space taken by this card, which covers a extra PCI slot for each card installed, which I need to be able to use, I got to tinkering and removed the cooling shroud to see what would be involved. At first I was hopeful, because the card itself is very thin and all that I thought would be necessary is to replace the PCI slot cover with one from another video card of only one slot. But after Googling, I found a review comparing the Zalman and ZeroTherm coolers designed for this card:

http://techgage.com/article/geforce_8800_gtsgtx_cooler_comparison/

It soon became apparent, with the height of these coolers, that neither would yeild any slot real estate for other purposes. Does any such critter exist? I also noticed that everything except the GPU (which used thermal grease), used thermal tape. Is there any reason that I shouldn't use thermal grease instead? Lastly, I noticed that the layer of thermal grease that I had to clean off the GPU was very thick, much more than I would ever use for a CPU. Is there a good reason to use a thick layer again?

Now I know that this question is not one that no one here has any experience with, I sure could use a little input. If needed, I found some Sekisui 5760 Thermal Tape, which the vender says has a strong adhesion quality, but the old tape that I removed from the card seemed to have none, it scraped off without any effort with my finger nail, yet even it took some effort to separate the cooler from the card.

The vender said not to use this on a CPU or GPU because it would be fried. These two things have me wondering if I should use tape at all? Therefore, I repeat the easier part of my original question...is there any reason not to use Artic Silver 5 on everything?

Some people say using Artic Silver 5 on everything is dangerous as it can conduct electricity. I used it all over my 6800GT and it died eventually. Was it due to the AS5? Who knows, but I've never tempted fate again and I used Ceramique for everything other than my CPU. For my CPU I still use AS5.

For my CPU I still use AS5.That's interesting, and more than enough to prevent me from using AS5 on anything other than a CPU or GPU. I've not dealt with Ceramique before, but after a quick check, it appears to be as easy to use as AS5, just a different forumula. Is there a particular reason that you choose this, rather than using tape pads like the originals? I know that the thermal pads that often come stock with new CPUs are usually removed in favor of AS5, but I always thought that was only due to a superior thermal quality of it, is there any other reason?

I finally found something on eBay that is a half-way affordable solution:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320283532875&fromMakeTrack=true&ssPageName=VIP:watchlink:middle:us

But I have never dealt with any kind of water cooling before. The only reason that I want to now, is not for sound reduction, only to make the video cards fit my MB. This water block is far cheaper than what most people have suggested, which makes me wonder if it would really do the job? Do you believe that it would keep the video card at a temperature at least as cool as the stock fan?

I realize that there would be other components needed, but this vender has most of them available in his list link. I'm still trying to figure out exactly what I do need? Could someone help me there also?

that water block is not for you. it doesn't cover the memory chips and they will fry if left exposed. if you want to go water cooling get a block made for your 8800 gts and use that.
in addition to that you will need a pump and radiator and maby a reserver

Are you saying that using heatsinks available separately are inadequate? Can you recommend a water block that would cover all of the other chips and ram that would be thin enough to permit the card to function within the confines of one slot? That is my entire purpose in this venture, to use the cards in SLI without losing the surrounding PCI slots that I need.

no I'm not. I'm just saying that that one was no good and that its very hard (and risky) to make a water block from non 8800gts intended parts because ther dont always fit right. give me a few miniutes and I'll find you one.
EDIT:which version of the 8800gts do you have? 320, 512 or 640?

G92 8800 gts 512 (http://cgi.ebay.com/2-Nvidia-G92-water-blocks-8800GT-GTS_W0QQitemZ220270142361QQihZ012QQcategoryZ3762QQ ssPageNameZWDVWQQrdZ1QQcmdZViewItem)

this (http://www.newegg.com/Product/Product.aspx?Item=N82E16835118028)one may be dual slot

They are 640mbs, so anything for the G92s are not going to fit. The block in your link has no specifications given, so all that can be done is to judge via the picture, and that is very difficult to do. Perhaps I can find the specs later, when I have time, but as it stands, it looks like a dual slotter to me.

You say the one that I gave is no good...what is the basis of your statement...personal experience, or just a generality about anything that is universal in nature?

The problem with the one that you linked is that it is $100, which multiplied by 2 + an unknown amount for the other components that would be required would make water cooling financially impractical for me.

Even only using 1 8800GTS costs me 1 PCI slot, that I don't want to lose, so my only other choice is to simply use a BFG 7800GTX OC that I have instead. This latter option is looking more and more like the winner for me, but I hate to just have these cards sitting in the closet.

EDIT: I failed to notice your third link, until now, but it is 31mm thick, which converts to ~1.2"...it is out of the question.

the bloc is fine but the resion I said its no good is because it doesnt cover the memory and because I don't think they have a stand alone memory water block. however if you find one then by all means go with the one you found. I'll keep an eye out for G80 water blocks.
EDIT: the third one is G92:(

The memory isn't covered by a water block unless it is part of the GPU water block (all in one). When a water block such as this is used, the memory uses separate heatsinks, and these are available. The only thing that I'm not certain of is heatsinks for the regulator, mosfets, etc., but then I'm not certain how critical that they are.

This (http://www.dangerden.com/store/product.php?productid=272&cat=48&page=1) will work its just expensive.
EDIT: and what do you need the extra slots for?

seeker
08-18-08, 11:18 AM
Too expensive for me. However, DD does have some single slot VGA PCI brackets that I need.

seeker

Here is an example of combining heatsinks with a water block:

http://64.233.167.104/search?q=cache:fcaPKgpR1DUJ:www.sidewindercomputer s.com/swmcvgacowim.html+13mm+G80+vga+water+block&hl=en&ct=clnk&cd=1&gl=us&client=opera

I can't use this one, because the water block is too thick. I also noticed that the heatsink nearest the PCI bracket would also be a problem, because it is elevated above the others (is that the regulator?). I guess that is why they show it still using the original double slot PCI bracket.

Doing anything with an 8800GTS 640mb apart from upgrading it would be a false economy, Why not just sell them and buy some single slot cards?

I ask also ,What do you need the pci slots for?

If I wanted the latest/greatest card, then you would be right, but since I'm upgrading MB/VGA from AGP, this should prove a considerable improvement, and that is not a false economy...unless I spend too much for cooling them.

I ask also ,What do you need the pci slots for?
Sound card, TV tuner, raid controller, WiFi and anything else that I decide that I want.

I thought you were considering WC, maybe you arent.

seeker
08-18-08, 03:31 PM
What have I said that makes you think otherwise? WC is exactly what I have been discussing through most of this thread, however it shall be limited to only the video card. The CPU and other fan cooled items will remain as they are.

rage10
08-18-08, 05:37 PM
if you want heatsinks and WC then going with this (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320283532875&fromMakeTrack=true&ssPageName=VIP:watchlink:middle:us) block and which ever heat sink you think is good (copper is best). just make sure that you have very good case ventilation because you need a fan to take the heat off the heatsinks. you will most likely see a increase in memory temp and a decrease in core temp. eather way hope it works.:)

rage10
08-18-08, 05:44 PM
and make sure that you buy a NON conductive solution

seeker
08-18-08, 06:03 PM
I guess that we have gone full circle now, except that I'm still not sure what to use on the regulator, if that is what the item with the heatsink nearest the rear I/O panel in the post #15 link is, because of it's elevation I can't use the heatsink as in the picture, because it would cross the single slot boundary, which leaves two questions...just how critical is the temperature of this item, and is there a much lower profile means of cooling it if necessary?

seeker
08-18-08, 06:18 PM
You can disregard my last question, because it is irrelavent. I drug out the video card and found that I had things reversed in my miind. It is not the regulator that is elevated, it was the metal stand on the original cooler that was elevated. So I guess the solution is to get the eBay water block and the Swiftech heatsinks and the DangerDen PCI Brackets and I will be ready to roll. I've already ordered some Ceramique to use for the GPU, but I shall need to get some thermal tape for the heatsinks.

rage10
08-18-08, 10:29 PM
but I shall need to get some thermal tape for the heatsinks.give me a link to what ever you choose if you don't mind, I need some. Also when you assemble the system, put the parts where you want them to go and measure and install the hoses the remove everything, fill it up and wet test out of the case for a day or two to ensure of no leaks. Also, be sure of adequate case ventilation. Good luck:)

08-18-08, 10:44 PM
if you go with the ebay block the I think you should point the nozzles towards the front of the card so don't have two go over the heatsinks.
