lmfao that's lame... just stick to liquid cooling
You would need to have waterblocks for the fpga's custom made then.
They do make universal waterblocks. If BFL would just put some damn holes in the board. They make water blocks which can adjust to everything from 28mm to 80mm hole spacing.
BFL just punch two holes in the PCB and people could use any custom cooling they wanted. It you can't/won't for this board at least consider it for the next board. Having 2 push-pin holes put into the board would add about $0.02 to PCB production cost. Everything from third party CPU coolers to waterblocks to phase change and TECs would be possible if they had 2 pennies worth of holes punched into the board.
Now that's news to me. Can't we drill the holes in, aftermarket style? Or is it the PCB's so damn packed till we can't even drill em ourselves?
The board is very tight. Generally you would want the board designed for holes in particular. Also a PCB shop will have very high speed drill presses with tapered bits to ensure no slipped bit = destroyed $600 board.
The other issue is it looks like BFL used a thermal expoxy for mounting the heatsink. You aren't getting it off.
However if BFL offered a board with
a) holes in PCB for mounting heatsink
b) no heatsink, fans, case, or powersupply
c) offered it for $30 less
you could make a monster watercooled cluster.
Send them an email asking them for that. They likely won't but if they get enough requests maybe they will consider it for next revision of the board.
