Turn your ASIC on by clicking the 'turn on' button and wait! Keep the temperature below 50°. Soon after it exceeds, you'll blow up and have to restart! To cool down your miner, simply turn it off for a short amount of time. You won't be able to get the temperature below 5° once you've started, so don't worry about that. I'm intending to add more miners that you can unlock and more accurate prices & rates in the near future.
