Hello,
I have done quite a bit of research, but haven't found a proper answer yet.
I live in Canada and would like to build a little mining farm out in a shed made of thin steel.
Here it gets bellow -35 degrees Celsius, but miner temperatures go down to only 0 degrees.
What would happen if i had them running in this shed? Wouldn't they heat up the shed enough to keep it warm? Or would they just create moisture and shorten out?
This seems very dangerous...
What would you guys recommend?

I have tried running a few S5's in balcony through last winter. Surprisingly they all survived without any issues at around -20. Below this temp I didn't run them. To prevent dust I put them all under a sofa cover. Fans usually were under 3k rpm. Only time I had problem with it was the router failed to boot up. (yea i threw a wifi router on balcony as a repeater of my main indoor router.)

Did you not have any issue with them getting wet? I thought if you run them in extremely cold conditions the heat would cause condensation and then you would start getting water all over your miners which everntually would cause big problems. At -20 i thought maybe your fans could seize up as well unless you were running them without them due to it being cold enough already?

Well of course you need to ensure there would be no tons of snow around your miner. Some slush was fine for me. The sofa cover helped a lot because it was breathable but also kept some warm air inside it. This made the cover like an inflated balloon. inner temperature would be around 10 degC.

You will need to play with the cover a bit so ensure it allows air flow to enter from the bottom tip, while also allows over heated air to escape from the top by poking a few small holes (1~2 cm diameter).

Haha Awesome ! It seems like a nice setup. Do you have any pictures ?
Wouldn't it be better to store them in a cold place in your house, like a basement ? At least this way the heat would not be lost and you could save a few bucks in heating.

Thats only if you have a basement. Luckily I don't! Cause everyone around here has flooded basements every summer.

Have you considered watercooling ? Grin

But why are basements flooded ? Is it because of a lack of isolation or simply because most houses are not very well build and water flows through cracks or something ?
