Homemade 8800 GTS Water Cooling

Hey everyone!

 

I'm new to this forum, and just wanted to know, if anybody on here is experimenting with building their own water block for their graphics cards??

 

I just did this concept design for a ZOTAC 8800 GTS 512MB, that I will do some test runs on soon.

 

Thinking about using Firestrike, Furmark and Heaven for comparison of the stock cooler :)

 

The design was made in SolidWorks 2018.

Not really my thing but I do can tell you, do not use FurMark on a 8800 GTS, it'll be dead within the first 5 minutes of stressing, stick to Heaven only.

I don't (and I don't think many do here).

 

Admittedly I don't really understand the design since there are no microfins or obvious channels for the water to go through, or the O-rings for sealing. G1/4 threads. so on - perhaps a bit of annotation could help?

 

Another is the need to watercool such an old card, although I appreciate it's probably for fun (which is a fine reason). 

Recent builds:  Meshify C (Zero Tolerance!) & View 37 (Breathable Quad 2080Ti + 2990WX)

Best documented PC coolants

Older Builds

Full-custom loop builds: Meshify C (Full custom loop SLI), Ncase M1(8700K + 1080Ti Full custom loop)  Obsidian 900D (1950X + Quad 1080Ti) & Fractal Define C (1080 in SLI)

Air-cooled builds Air 740D (1920X + Quad 980Ti) & Fractal Define C (Version Air!)

Will do .. however, might put it on fire later, if the cooling is working xD

i agree with @Princess Cadence furmark is going to cook that card

I'm a trained machinist, so that's why I'd fiddle arround with these projects xD

 

The o-ring would do fine with a NBR-70 seal .. M10x1 for the studs, making my own probably ..

That copper thingy is 56x56 mm - no fins, cus .... it would be cheaper to produce, considered I don't have acces to a shop .. And it's just for a school project, so it'll do :)

adding just large fins in the machined surface would go a long way and shouldn't increase cost as the machine would be removing less material and thus it wouldnt exactly take much longer. Just doo 1mm wide fins 1-3 mm deep?

Needs fins inside the heat transfer cavity.  Simple flow path blocks have been insufficient since CPUs/GPUs went over ~50w.

Can the flow rate and the normal temperature of the fluid medium make up for this? :)

Nope.  Temp differential will be massive between the core and the medium because you do not have sufficient heat transfer area.

I know, but .. it requires small expensive tools and machines with high speed spindles .. but ya, surface area is key! :)

and so where does the water go in? and where does the water go out? is there another piece that is meant to fit onto this?
