Zippyc sharing 9700 Pro Memory Water Cooling Loop Idea

[zippyc]

I'm posting pics of my 9700 Pro MEMORY watercooling solution I built at several forums to share the idea for those who wish to replicate it. Thanks go to Foxx at AMDMB forums for hosting the pics.

Feel free to ask questions if you have any...

O_O sooo many points to spring a leak

[Stalka]

very cool. that is one of the neatest (clean wise) ram water coolers i have seen. very nice. can you share where you got all the supplies? and total cost, etc...

::EDIT:: also how is it attacted?

[tony-da-tiger]

looks good

[drunksquirrels]

are you gonna vmod the memory? otherwise it would be useless since BGA memory runs really cool.

[Stalka]

my 9700pro's memory runs hot to the touch when im not even playing games, nor overclocked. :/

[zippyc]

Simply got the 90's (Brass elbows) from professional plumbing supply store. They ran around $2.00 each (I used 10).

Mapp torch, solder, resin at home depot, about $20.00.

Temps? (All measurements from same physical spot under madonion nature stress.)

At 360 Mhz and factory cooling, I read 60C on the memory.

Air cooled with copper BGA airsinks I got 47C

Water cooled I get 2-3C higer than my H2O (Max of 34C under load)

The cool thing to report is that by removing the cumulative heat of the memory from my PCB board, my GPU temps wemt down another 5-7C! (Associative heat!)

;-)

Attached very carefully! (lol)

Used loads of masking tape to protect the card from scratches and erroneous adhesives.

Then I used artic silver epoxy. Pretty permenant. If I pull this card from a water sytem I'll probably leave the fittings on as air sinks. I have pulled some off before after using this particular epoxy after freezing and twisting....it will come off, but is risky and as fun as pulling teeth.

That's one of the best DIY ideas I've seen in a long time. Better than buying a machine press to cut one out.

Very nize man... so good lah. I would realli like to see how well they can OC with max v-mod and everything.

[SuperSlow]

Man that is beautiful!

I'd love to get that done to my radeon

[twiztdskatr]

NICE!

You should have put a dot of superglue and used AS3 on the ram, that way it would have twiztd off easy

did u lap the 90deg elbows too?

[zippyc]

Stalka,

Yes I lapped the two surfaces that mate to the chips simultaneously after building each block, This ensures that the mating surfaces are dead even (on plane) and allowed excellent fit (contact) on each pair of chips.


I started with a flat metal rasp, and then 100, 200, the 330 Grit sandpaper, followed by 000 and 0000 steel wool for the surfaces that will be showing after mounting. I actually ended up lapping both the buisness side and the show side of each block beacuse it also improved looks...but I deliberately just got it "good enough" on the show side and concentrated hard on making the business side really smooth and even.

Then brasso and rags....(my wife HATES the smell of brasso, so I was kicked out to the garage for a while....)

Lot's 'o work, but I am happy with the results.

i dont see them help!! i wana see these pics!!

[1st timer]

Very nice... quality work...

the 3 links work fine for me...

[drunksquirrels]

if it says image is forbbiden to be linked just highlight the url and hit enter

[twiztdskatr]

yep, i saw em, now i dont.

[zippyc]

Well, looks like my images at the other site are blocked, so here is my attempt to post them directly.

I posted on a couple of forums to share the idea...one of the things I enjoy about the overclocking community is that idea sharing breeds better success for all of us....my design has already been improved upon by suggesting we lighten weight by using plastic fittings on the top-to-bottom transfer that I chose to make out of brass.

Not as pretty but probably better from a weight standpoint.

Oh, and the fittings I used were all ½” ID, and the hose used is 3/8” ID.
