Hi,
Its just 2 days I started mining with s9 and all going well as it's winter time and getting 14 Th/s
However in summer temperature in my area reached 40c+ c and sometimes to 50c also (104-122 F)

I am planning to increase my mining capacity and want to order new machines.
What should I do?

Will s9 would work if temperature reach to 40c (104 F)? At what capacity?

Would L3 be better option?

Suggestion would be appreciated.

Regards
Salman

You will need to get those ambient temperatures down quite a bit if you want your machines to run in the summer. They dont downclock from heat, they just shut down the miner until you can restart it so you will have a constant battle restarting miners all day every day. You need to get those temperatures within reasonable limits. You want to aim for say 25c ambient intake temperatures if you want these miners to be stable and reliable over the long term.

Stop buying industrial miners, running them at home, and then complaining about the noise.

Hi
What people are doing to overcome this problem?
Air con won't be feasible as it consumes electricity.
What about Evoperative cooling?

Proper ventilation. We use exhaust fans to expel the hot air that is coming out from the miners and at the same time suck in colder fresh air from outside. Exhaust fans are cheaper to operate than air-conditioning system.

I will not recommend evaporative cooling because it will humidify the air which is not good for electronic devices. This is good if you are in a very very dry climate area. But if you are in a humid area, this will be bad to your miners. SO i will not risk it.

There are many ventilation threads here already that you can read through the discussions to get some ideas.

This is wrong, please disregard what he said. Evaporative cooling is what a vast majority of large scale bitcoin datacenters use to cool the incoming air charge. In a place that is so hot an dry this should make a large difference. Ventilation is good but if you are bringing in 40c air from the outside its not very helpful for cooling.

I have experience working with Evoperative cooling as I managed a poultry house some time back which is based on same system. Maximum I can cool down was 5 Degrees

I have seen a video where a guy installed 2 tons x 2 AC = 48000 btu to cool down 15 machines.

What other people are doing?
