Silver Slug core? plan, any thoughts?

maverick215 · 05-01-2002, 09:18 PM

I was thinking about trying to build an H2O block this summer and I have this nice Silver 1 Oz spot round..
My thought was to take a copper block and mill it out with a drill press etc etc here's my plan
1)Using my odd size drill bits (so to not ruin my common ones) I want to drill several holes in a spiral type design or perhaps similar to Maze3, first off how many drillbits do you think I need to complete a spiral type design? I of course plan to flood with cutting oil...
2)might need to do this first haven't yet decided, drill out a round center for my silver slug to mate up on the cpu, I will then silver solder it in place and sand it down flush.
3) Mill out my design in the silver slug perhaps I will silver solder thin fins of copper to increase SA.
4) How thick of a bottom should I leave on the block? 4-5mm?
5) Aside from the Gwhiz I'm running silver and you're not factor, how much temp gain should I expect over using a solid copper block?
6) I plan to silver solder a thin copper block to the top of the finished unit with tapped holes for barbs etc etc....
Any other thoughts are welcomed..

Wow been ther done that. Your temp's wont be incredible. You will probably nitice a 1c drop or so. Here are some pics for you to give you some ideas:

I also caame up with a second version that was bigger with a bigger silver pice in it that did much better but I don't have pics of it. I'll try to post them in a few days.

Don't pay any attention to the temps listed there the system was not set up correctly.

seems that 1C isn't enough to go through all that trouble... atleast not for me, thanks for the input..

You may see a little bit better but I don't know for sure. The silver isn't to expensive. Thats why I tired it but you get much better temps and results if you use at least a 2 troy ounce pice and if you can find a 5 troy ounce pice it whould work even better but cost starts getting in the way.

yeah I thought about using a rectangular piece (5oz) or 10oz

but that runs about $50
or

hehe
more fun would be had with this 100oz bar I imagine
http://cgi.ebay.com/ws/eBayISAPI.dll...tem=1348707393
but like you said those pipe dreams are a might cost prohibative...
I think I'll just pick up some copper stock and have at it,
for those interested I think that the 100oz is like 64.00 mm x 165.00 mm

yeah it's just the thermal interface that stuffs it up, might be an idea to make the entire thing out of Silver

I used 4-6mm drill bits to drill out the channels at first, then went to 10mm. I didn't break/damage a single drill bit, I didn't use oil either.
