Can a baseplate be too thin?

[harleybro]

Ok have been trouble with making my gpu cooler. The main reason is the bolts. Taps tend to bind in copper. So here is my new idea. I have 2 DD maze4 gpu blocks. I just disassembled one. I plan to buy copper pipe to fit in the spot where the O-ring was. I would use a small piece probably no longer than 2 inches. This would be brazed right onto the baseplate. I would then have a copper tube between 2-3inches in diameter with a cap brazed on the bottom. Then drill a hole through it so the first piece will slide in and braze it together. My biggest concern is my baseplate the DD one is only about 1/8-1/4 inch at the minimum. would this be a problem? I figured I would transfer even more cooling to the gpu this way.

your base needs to be 7mm - 1cm thick,

just look true some gfx cooler designs.

this shoudn't be a problem or?

1/2" is the best for a baseplate, temps will not swing too much, 7mm is too thin.

Well here's the container.

The base was only around 1/8 in thick.
Im building a container for this weekend with 1/2 in. base. I'll post the results here. ;)

Well I made a new container for my GPU. I used 1/2 inch thick base with a 2" elbow and 2" X 12" tube. I made dimples on the inside of the base. All in all I am somewhat disappointed. I did gain about 5-10mhz on core and thats about it but I think my GPU is maxed out. Also I am having a bit of a problem getting it to make good contact. I would say a gain of 5mhz. but when I pulled off the container it only made contact with about 80-85% of the core one edge was not in contact. Hopefully I'll find out what was causing it to not touch and get some better results this weekend.

i see you made that 90° container, can you give some pics of the before status and maybe tell how you make the hole to put in the container.

i tried but sawing a hole into a tube isn't that easy, perhaps you drilled it or?

greets,

Those are the only ones I took. I may be disassembling my other maze4 this weekend. If I do I'll get a picture of it. It is a square piece of copper with a big circle around the edge. That's where the o-ring sat. In the center of the circle was the danger den maze design. I brazed I think it was 1 5/8' tube into it a small pice maybe 3in long. The tube with the cap brazed onto the bottom I used a drill for the hole. Like these (http://www.coastaltool.com/cgi-bin/SoftCart.exe/a/ab/leno/holesaw.htm?L+coastest+pydf4181ffec4dec+1115686821 ) hole saws. It did want to move a little but wasn't too bad. I then used vice grips to set it how deep in the hole I wanted it. Then braze and insulation. About the 90 did you mean this one? lol

the left on is easy to make, and good to insulate.
i won't use the right one, to close to the card:)

tnx about about the centerdrill, i'll maybe buy one.

[harleybro]

I liked the idea of the one being close to the card was hoping it would cool my memory also a little extra ;) The hole saw does work very well and if you are planning on trying like that again I recommend using one. The one on the left is what I am currently using but something possibley a chip is holding it from sitting flush on the chip I still need to investigate a bit more. :)

[Jort]

about the memory you should make a problem.

the card freezes completly through.

I used a pelt on my 9600 xt and the mem was freezing also:)

[harleybro]

:eek2: What size pelt was it? What was the water temp you used to cool it? Did a 172watt w/ ice water myself but don't think it was freezing. :)
