So..is someone building one of these prototypes yet..or what? Any new designs or additions to the ideas listed here?
post #452 of 753
You know what I want to make. A backplate waterblock. If someone made one of these and it was even only worth 2C, but universal....they would sell like hotcakes.

The only trick is the limited clearance to the motherboard tray, but if you've already hacked a hole in the tray, you could almost just take your favorite flat block, put some sort of electrical tape on the base and mount it up with some extra long M4 studs...

Although a nice large flat block would be even better.

Hey I forgot my hack saw block, still need to make a brass jacket and solder it on and all that, thin the pins out a little more...Its will be a triple barb center inlet, thats why the center is lower, the top will come to the top of the pins so flow will be forced through the taller ones to the outlets..

Notice how the pins aren't symmetrical? Thats a design concept,its not by random chance...

I really do need to finish it and use it as a TEC block, see how it works, it took a while to saw that out, once I had that much done I lost interest in it..Solder the jacket on then I can lap the base thinner...It might look better when I get a jacket on it, maybe, if you look at it just right, in low lighting conditions, wearing sun glasses, maybe..

Wow, that's great! I would have never figured something that detailed was possible by hand. It should work perfect as a TEC block too. Nice!

Now I'm going to have to figure out a way to set my slide vise up to the bandsaw...

Your pretty handy with the tooling, Martinm..any chance of you building an inter-changeable top for my GTX?

*Great work Ira..thats a lot of surface area!..and a lot of patience!!

Thanks..I was thinking about using a old table saw trundle with a long neck Makita die grinder on it with a slitting saw blade, with the trundle I would have the height adjustment...Then a cross slide vise to hold the copper..Might be hard to get the slop out, but if you boxed in the trundle with a tight side to side enclose it might work...Might just make a 200mph slitting saw projectile to..

A band saw might work real well, save all that milling time..Tighten up the blade as tight as you can get it with-out breaking..

Thanks CL, It really didn't take that long, I just did it off and on for a while, keep the blade coated with wax and it cuts pretty easy...Held it in a little hand vise...

I need to get some brass for the jacket and mounts, the hard part is done now..Good winter project there..

I am a total novice to water cooling and specially home made water cooling, I have been reading these many articles including this one about water cooling from some days, I need some starter help on creating my own water block, i have seen the blocks you guys have created, pretty impressive work.

The problem is I don't own a mill as well as all the professional tools you guys have, a few days ago i just purchased a solid block of copper but i don't know how to start my work

First of all tell me what thickness I use for the block, the block i purchased is quiet heavy and its half inch thick I think its not a good idea to use that much thick block, so please tell me what thickness I use, I want to start my work by creating a block for my XFX Geforce 8600 GT.

Secondly tell me what alternative I use for mill machine, I also don't have a stationary drill , however I have simple 800 watts black & decker drill machine with titanium bit set, is it possible that I use my drill machine to make area inside the copper or I have to use that traditional dremel and hammer method which I think is very difficult ?

Thirdly tell me how deep should i make the area inside copper for optimum performance, I know I am demanding too much (optimum performance from a handmade block).

Last question (Not related to creating a block), Copper is very expensive in my country (Pakistan), is it good to switch to Aluminium in the start ? I know that thermal conductivity of Aluminium is quiet low as compared to copper but it is cheap also, so if i waste it no problem. I want to ask what kind of cooling performance I can expect from a pure Aluminium water block and is it safe to pass water from Aluminium block I mean some chemical reation or corrosion ?

Sorry for asking so many questions at the same time, but I am very much interested in creating my own water cooling system.

I wouldn't use aluminum, except to practice on, its C/W is lower, but the main reason I wouldn't use one is because of galvanic corrosion in a copper and brass loop..Now if you used a aluminum rad to it would be fine..

You can drill out a spiral pattern block pretty easily, just cut slots in between each hole, I'd make them kind of big so you wont have to much restriction..I think fstfrddy usually makes the lowest part of his base 0.080" thick, thats really thin and will transfer heat well..

Up above there I left pic's of a hack saw pin base block, easy to make, I just need to solder on a brass water jacket and make a top and mounts for it..

Take a look through this thread, there are a lot of block ideas and links, tips..etc..

I see that some people are using automotive heater cores and I saw on E-bay one guy selling adapters to use the main radiator from a small car, the main problem with this is that around the mid eighties the auto companies switched to Aluminum cores with Plastic tanks now Tahiramed lives in Pakistan where it is hot most of the year so a radiator from a small car using a box fan would really help keep things cool, plus the radiator would be super easy to fill.
