Giant B received today as part of group buy from itop with another member on this forum. It's a little noisy for where I was hoping to run it, will consider selling for 0.9 btc + shipping fees. pm me if interested.
Hello,
Why not use passive cooling.
NOISELESS BIT MINING

1. Get a plastic tub with a lid that is at least twice or 3x as large as the Giant B miner.
2. Put the Giant B miner in the tub.
3. Fill the tub with Mineral Oil (which is electrically non-conductive) .
4. The Giant B miner will only generate heat, and No Noise.
5. Don't bother putting the power supply in the Mineral Oil.
6. You may have to run a small fountain pump in the Mineral Oil to circulate the fluid around the Tub.
7. You may have to run a small fan (quiet, not necessarily fast and noisy) across the top of the Mineral Oil to remove the heat.
8. The plastic tub will radiate a lot of heat around its perimeter. Which the external fan (Step #7) will wick away.
