Topic: Placing machines outside on cold winter? -20 (Read 16759 times)

Should work with the mentioned conditions, BUT ...

... if you ever get a service interruption (power goes down) it will get dangerous with temperatures under +12°C for hardware.
And with under 0 and colder --- Your hardware will start to "sweat" in some seconds!
And power comes back after 1-2 minutes it will first slighlty work --- then the thin water-ice-condense will get back to liquid again and .... BUZZZZZZZZ  

Within a datacenter the airflow should not be under 16°C (and not over 23°C - some are even doing it with 26°C - cheap mass hoster!)
Humidity should be max 30% - most prefer lower!
Really hard - you have to drink water and water every minute you feel thursty

Without wet-problems it wont be such a problem. But you cannot lower the % of dryness without climate control.


What you should really try is:

1) Cold air from outside
2) Warm air from inside your box (circulation)
==> Mix it (maybe you get a twister) 

On a cold day you will re-use more warm air (more circulation, less cold new air).
On a hot day the air will be to hot from inside, you always will get fresh air.

Well - you need ...
temp measurement
airflow control to regulate which air you need more and less for openening a cold air valve or closing the warm air circulation etc.
(reducing the fan speed or increasing the fan speed could work too for each valve/line)

But in case of power interruption maybe some warm air from inside the house would help. (3th valve)
But it wont work automatic without APC/UPS (power is down)

It burns their electromotor.and reduces the power

But what about unfavorable conditions for the miners if you expose them to the very low temperature? I agree that electrical circuits might work more efficiently but how do you manage to keep miners without excessive moisture etc ?

If the temperature is low, the electrical circuits will last longer and work more efficiently. My miner works better in winter.

in cold seasons if we are placing the machine in outside indicates that we are decreasing their lifespan. the machines productive capacity will decrease by itself. so i think its not the good idea to place outside

cold huh https://www.youtube.com/watch?v=nJDsTqU3bJA  

it does not improve the hashing, but it will improve the lifespan of your machine, which is pointless in the asic world, since your machine will be obsolete quickly, unless you have free energy

you need to override fan settings for miners outside.
I used my garage last year.
 (Michigan) I saw alot of failures due to hotspots, keep the fans blowing all the time, it can be set to lower sped, but circulation is important or you're going to end up with potentially damaged equipment.
or just a fwe large fans blowing across the whole farm is another option if you have the room.
but at least tarp to walls to keep moisture out

I leave my laptop by te window wen its cold and it does mine faster

Almost all miners are built to run at room temperature, cooling below 15C is the realm of overclocking and overvolting

Just a noobs question: Will bringing the temperature very low improve the hashing rate? Is lower the better?

I tried putting a small piece of dry ice on my Redfury (about 2 years ago) and it didn't improve the hashing speed at all...

Actually it's how much time you spend in the room with the miners what's matters. Toxic materials go into the air always when heat is applied but not as much as to poison you right away. Don't spend a lot of time where the miners operate and you shouldn't sleep there that's for sure.

There has been a lot of debate about this, even a desktop PC will release *some* voc's during it's lifetime. On the plus side it's been agreed that a 1500M household air filter will negate any potential exposure.

As long as the temperature of the PCB is less than 300 degree, there is no problem about toxic materials.

i was thinking heating with miners is not healthy, as the electronics are releasing toxic materials into the air.

This is a bit off topic, but yes, of course I'm wearing wool: wool sweater and wool socks. And when I sit behind the computer more than an hour I use a wool blanket to cover my legs. The big advantages of the fresh air I have in the room are: no headaches, no fatigue. You should try it yourself.

Oh for sure, they do these kinds of things and they can be done but they are in situations where they're basically using commodity hardware (for them) and have environments where the failure of a machine, rack, row, or even in extreme cases entire data centers doesn't translate to lost service to customers. They can afford to be pioneers and push the envelopes. Most of us simply don't have this type of ability in our houses. They save money on power / cooling equipment and just accept a potentially higher MTBF of server equipment. I worked at a "big company's" data center in Seattle for a while where they had a tent outside that was basically protecting servers from the rain. Intel did similar things. These types of endeavors are what have helped open up the TC 9.9 operating window. It used to be a max of 68F back in 2008 (iirc) but it has since been raised to 80.6F for the cold aisle (inlet) and even in some classes of machines as high as 104F

You're seriously comfortable at 15C inside? Are you wearing wool? ^^

That really depends on many things:

1. The size of the house

2. How many miners you have

3. The temperature you want in the house

For example I'm okay with around +15C in my room so even one miner would be enough to make me feel comfortable. Of course I live in a flat surrounded by another flats which are warm.... so maybe tha's why ... Yep, for the entire single house one miner is definitely not enough.

The amount of heat output is not enough to heat an ENTIRE house.
