Excellent work! Thanks. How much is room temperature?
it's about 20 degrees Celsius at the time of taking that screenshot.
There is any extraction fan?
Yes there are, I use a split-room design to separate hot and cold air, the ventilation is not perfect but it's pretty good, you can refer to this
topic .
So watts used would be nice.
Unfortunately, I don't really measure power consumption per miner (i guess you know why

) but once/if I have the chance to do it, I will be more than willing to do so.
