Possible to Swap Antminer S1 Heatsink and Fan onto Gridseed G-blade 80 chip pcbs

[chisefu]

I'm just curious if anyone has tried this, I searched and didn't find anything.  I'm thinking of ordering one of those 2.6mh/s 80 chip PCB's, and I have a few S1's laying around.  It should be possible, even if I have to drill and tap screws, but I'm curious if anyone has the dimensions of the gridseed pcb?

Why would you want to?
Or are you getting JUST the PCBs without their own HS/fan setup?

BTW, it's 40 chips per board for the "2.6 Mh/s" (appx) boards - 80 chips was for a 2-board 2-part HS full miner setup at 5+ MH/s

My miners of that type are still packed up, but estimating from known dimentioning and measuring from the box, the part of the board that needs to have the heatsink/BIG THERMAL PAD applied is roughly 4.5" by 10".


Note that these old miners are at best break-even if your electric cost is over about 4c/KWH.

Are you selling them?

Thinking about it, but if I move soon to the area I really WANT to be in, they'll actually be profitable (for a short while).

The reason I want one is because I have a 300w inverter on my 200w solar panel array.  I have the deep cycle battery capable of running one of these for about 6 hours a day without going below 50% of the cell's capacity.  Right now I'm just using a gaw fury, and I thought about one of those stick USB setups but they want  80 bucks for 500mh/s (the moonlander).

If I ran this with just a single 2.6mh/s 40chip PCB, that's only about 50 watts.  I was thinking I could just rest the pcb on top of the antminer heatsink.

^ All I would have to do is set up a fan or something to blow against the heatsink, so I think this is the direction I'll go.

holes on the heatsink use a standard 92mm fan, and doesn't have to be super-high flow.
Actual power usage is under 45 on all of mine, more like 40 even on the no-fan ones, using bricks I got from Zoomhash.

You need to put a big thermal transfar pad between the PC board and the heatsink and screw them together - that the ONLY cooling the chips get, and they will NOT stay cool without good solid thermal contact.
IMO the termal design of the "blades" was very very poor.

 Also check into the threads on litecoin talk and here about adding heat sinks to the regulator circuitry - or UNDERCLOCK the board - that was the biggest fail point on these miner boards.
