making a copper waterblock from scratch

[Warlord2]

has anyone tryed melting down pennies to get a block of copper?


there are no metal stores at all in my town and online they are $37 for a 2x4x1 inch block of copper


and does anyone know if copper will melt with just a propane touch?

my first block will be for either my video card or chipset

you are prolly going to need some thing with a little more power than that. I was meltting silver with an oxy/aceteline but that puts out about 5400*f if set correctly

hmm, if you are resorting to melting down pennies to get a water block, maby you should re think your design, what about a heatsink encased with plexiglass?

well it melted with the help of some flex

so I melted 9 pennies and it turned out to look nothing like copper!!

it looked almost like tin

does anyone know if this stuff transfers heat?

I may go to home depot and buy some 6 gauge copper wire if this stuff isnt any good

[Warlord2]

the sad thing is I dont trust glues at all

Ive had some bad experences with even jb weld

pluss I think it will be a greater defeat if I can make a block out of scratch


I dont need it any time soon so and Im basicly doing for fun and the challenge

were they new pennies? I know in england newer copper coins are only copper plated and are a dull grey metal inside, onlder ones are all copper though. Of course I don't know how good the quality of the copper is you may not get very good results from it.

yea I was just told on irc that american pennies (wich Im using) and mostly copper and tin.

so my question is now

will tin transfer?

or is it like lead?

Interesting idia how would u make it water proof?
And will you leave the HSs fins like they are?
And what about the clip? How will u mount it on?

no not very well, the only 4 metals worth considering for heat transfer purposes are silver, copper, gold and aluminium in that order (silver being best)
try finding some older pennies or if you have the dosh some silver dollars and use them

[Warlord2]

I dont think I have the heat needed for melting silver so I think I will go with copper wire

Maybe you could cast a waterblock with no seems using the wastewax method. Just an Idea . . . .

[Phil]

whats the wastewax method then?

[Warlord2]

I was thinking I can cast the whole thing but the bottom using blaster of paris as a mold



thinks for the idea dimmreaper

www.dangerden.com sells blocks of copper. A blank of copper ( 2x2x1/2 ) is only $5.00 The price of a water block isn't that bad. I think you would be better off just buying the finished product.

You could get a copper heatsink and solder copper plates on the sides and another on the top to make an enclosed box. Heatsinks that get converted into waterblocks work quite well.

Last post for a while :(

Why don't you just go to a coin shop and get the cheepest per weight silver coins and make your block out of that.

Interesting idea here... Never thought about doin that... I have several old silver coins that Ive been collecting thinkin I could sell them off... hhmm... maybe something a lil different huh? What kinda heat does it take to melt silver? Looks like I got some surfing to do... info on silver... But I understand your problems... No one around here sells sheets or blocks of copper either... Ive only got one place left to check out... But Im liking this idea much better.... time to start on some ideas!!!
