thanks for the info.
It probably says 12 chips because it is an adapted version form the A1, which has 12 chips.
I you click on the 'stats' page you should see the temperature per chip. Could you post a photo from that? (I need the number of cores per chip and the amount of chips)
And at what frequency are you running it?
When you have indeed 10 chips per board you should be able to go to 40MH/s

Chip Specs
• Developed on 28nm using very low power design techniques and best efficiency.
• Custom IC package with power bars for low voltage, high current feeding.
• Configurable in daisy chain mode for distributed work with up to 253 ASICs.
• Standard SPI interface with CS pin needed to enclose all useful SDI and SDO data.
• 27 highly optimized hashing engines based on custom ASIC cells up to 1.6M.
• Built-in redundancy architecture to allow for bad engines to be bypassed without affecting mining operation.
• Flexibility to configure the PLL clock and computation performance.
• Hashing power of 1.6M in nominal and 1.8M in Turbo mode.
• Power usage of 10W in typical nominal and 12W in typical Turbo mode.
• Supply voltage of 0.78V in low power, 0.84 V in Turbo mode for ICs.
• No need for special cooling, just regular top and bottom heat sinks plus fan cooling.

The Device Specs
• A Total of 2 boards with 10 chip on each board, Total 16 Chips in a miner
• Turbo Mode Hash rate 1.8Mhs*20 Chips = 35Mhs +/- 8%
• Power = 350Watts normal
• Size = 51cm—42cm—16cm
• Temperature = Runs cooler than the A1 miners
