waterblock question

[creepy]

Iv been wanting to cool the memory on my video card and i was wondering how would it work if i took a rectangular peice of aluminium or copper w/ a barb at each end and just had a straight hole going all the way through it length wise.

It'd work. It wouldn't be a whole lot better than the stock air-cooling, but it'd work.

What would work better would be to drill part-way into each end to put the barbs in, and then using a 1/16" drill bit, drill a honeycombed pattern of holes connecting the inlet and outlet cavities. That'd actually make for a fairly decent GPU block, and quite possibly better than many you will buy.

Yeh sure that would work

Take a look at our good friend Bladerunners site. He has done alot of this kind of thing.

Alright. Ill give the "honey comb" hole pattern a try as soon as i get ahold of some metal being that im pretty poor right now. I should be able to do this using "simple" tools correct being that all i have is a drill press,drill,dremal,blah blah so on....I dont have a cnc machine or anything special.

I'm sorry to say, but I think that doing the "honey comb" thing will be impossible, since the end of the hole will be left at the bit's primary angle. I doubt you'll be able to start the small holes at all.

You'll have to drill the hole, then use an end-mill to flatten the end of the hole. Then you can drill the small holes. If you have a real bench drill press then you should be able to do that. You'll have to take a trip to the local machine tool supply place. Just tell them what you're doing and they should be able to give you the right mill.

I thought the same till i check the web that slater3333uk posted. The guy that runs the web or whatever is quite creative basicly he takes the block and does the "honey comb" thing right into the top then he takes a peice of sheet metal if you will and solders it over the top of that.

Turns out this morning (still havent gone to bed from yesterday ahah) I dug around and found some block of aluminium i didnt need so i cut it to size of about a NB chip. Within a few hours i should have some fittings etc i plan to stick it on my gpu or SB (my SB gets QUITE hot and i onno if this thing is up to the task of a video card i dont really trust my own work aha) so ill let you guys know how it works

[creepy]

Any suggestions on weather I should put it on the GPU or SB. Dimensions are 1.25"x1.25"x alittle over .5"

Mark out the circle for the barbs. Part-drill the honey-comb holes first inside that circle. Make sure that one of the holes in the honey-comb is centered in the circle as that will help stop bit "wander". Use a nail to mark each hole as well. Drill the small holes about 1cm deep.

Now drill the large hole for the barb into the end, about 9mm deep (to the tip)

Now drill the holes through again for the small honeycomb holes, using what's left of the original drill holes to "anchor" the position of the drill bit into the holes. Drill them all the way through.

Flip the block over, find the central honeycomb hole and drill the barb hole using that as a guider. Drill the barb hole 9mm deep as well.

Tap the barb holes.

Follow up with the honey comb holes one more time to clear them out.

That could work if you can be precise. Don't forget to buy *lots* of 1/16" drill bits! :p

Well, won't be so bad on aluminum. But on copper...oh man!

Slow and steady wins the race.

Don't rush it. You don't want the drill bit to snap 'cos then the hole that the bit snaps in is next to useless.

Oil the bit up to lubricate it. You'll only be drilling maybe 20 holes or so.

Words of wisdom. If you can find some real cutting oil, that would perform better than a lubricating oil.

Good Luck!

Just go to any industry tooling supply store. They're everywhere, just that people typically don't know that they exist unless they have a specific need to look for them.
