Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH
Ofcourse, you need tools (that's a no-brainer) ... a dremel would be a good start .... but definitely not a task to be undertaken by feeble minded at DIY. But like I said, not that hard (does not mean it is easy!)
Having worked at my family's machine shop, programming CNC mills/lathes and Wire EDM's for a few years, if you can do what you're saying with a dremel and have it actually work, I'm sure we ALL would love to see that. 
Indeed. Pekatete is clearly so much better than us that I'd love for him to teach us how to manufacture high grade heatpipes from scratch. Because its easy, you know.
What on earth has it to do with you (dogie and bitchie) if it costs more or is hard to fabricate? This is a case of nit-picking gone mad. The initial post was somebody wondering whether a copper heatsink would work better, and I actually concur with them as copper is a better heat conductor than aluminium, but of course (EVERYBODY KNOWS THIS!) more expensive.
And for a person who claims to have worked in a family machine shop, apparently programming CNC mills and wire EDM's, this has to be a walk in the park! But hey, there have also been claims of people being millionaires at 13 and I would not be surprised if the two (pathological liars) are the same person.
It 'has to do with me' when you attacked me for no reason. If you don't like what I'm posting, ignore me like I do to you.
.... I wish a company made a copper option with heatpipes, could make a huge difference for overclocking.
Should not be that hard to fabricate on your own .... just need to find out what thickness of the copper slab to get, slice some slots / channels in it and then split a few copper tubes to for the fins that are slid into the slots. All you are left to do is drilling tapped holes for attaching the PCB. I wonder how cost efficient it would be though for just a handful of units ..... ?
Doesn't sound that easy to me. Unless you have a machine shop and all the tools necessary as well as the skills to do properly.
Heatpipes aren't something you can do yourself easily, they're not very use friendly to craft. Generally though, there wouldn't be much point making extreme stock heatsinks which add $40 and 400g of weight to everyone elses shipments when their additional capacity is going to be used by very few.
You've raised your ugly head again .....
If you find dealing with heatpipes difficult, leave it to those who don't (both in practice and comments). No one asked you to add these to your homebrews, and unlike you, most people are not penny-pinching skinflints ....
