I notice that the square chip closest to the LED is the hottest. Are you planning on sticking the heat sinks on this chip, or the heat spreader on the underside?

Both front and back if I can.
For the moment I stuck 4 of this little square copper heat sinks on the back plate, but the thing is still too damn hot.
I'm planning to remove them and attach a spare i5 heat sink I have lying around, problem is the 2 screws on the back plate don't let me place it properly, but I'm thinking of a solution.
The i5 heat sink I have is about 10cm wide and looks like this: http://www.ayagroup.com/images/D/E41997-002_2.jpg
See what I mean? That should take care of it right ?? ;-) It's so big that should be all right even as a passive cooler with the fan off.
The chip closest to the led is the one marked with "BE100" and it's the hottest because it's the chip that does all the hashing work, as it was also mentioned in a another thread.
It will sure be nice to stick a heat sink on that chip, the problem is that it is so small that those copper heat sinks I have might not stick to it firmly. And if for some reason it detaches and touches other pins on the board it might short circuit and burn the whole thing, and I don't want to risk it. If I find a smaller heat sink I will do it though.
