Based on the OP, (sorry I haven't re-read the whole thread recently), each FPGA has to dissipate less than 10W.
Are fans really necessary?
It seems that a pair of small passive heat sinks should do just fine.
Reducing both cost and total power consumption (admittedly minimally) and more importantly the noise level.

The idea seems good, another good option would be to use a large passive heat sink for the two chips at once, as do the Intel Atom not need ventilators.

This is really a question, but there are some necessary reasons.

XC6SLX150 's FGG484 package has a very high thermal resistance, the cooling system must keep the chip surface at a very low temp.
so, a heatsink and a small fan is really needed.

i also tried a larger heatsink without fan, but result is not very good. this function limit the power below approx. 5W.

I have to do my groceries at a distance of 15 km so I don't understand why this can be a problem ? Oh... no... you don't have a car?

When someone gets these let us all know how it goes.
I wanna get some FPGA miners, and i've been looking at Butterfly labs, because the product is so clean,
But this guy has Clearly working FPGA's
Where as Butterfly labs has yet to show working FPGA's

let me show you how a 15KM distance is a big problem...

i drive my CIVIC to the delivery station. actually 20KM away.

this is the maxim speed...



i leave home at 2PM and back at 6PM...

5 packages delivered successfully.

Beijing's traffic is a disaster. really, really. Cry
