BTU Output of L3+ AntMiner

[chipmonk1999]

Does anyone know that the BTU output is on the L3+ Miners?

I purchased Qty. 10, L3+ Bitminers that will be powered via antminer power supplies running at 240VAC.

These units are going to be in a 10 by 10 enclosed room.

Want to size a AC Unit that will keep them at room temp.

However not finding any information on how much heat they produce.

THank you

Hi, im not a miner but here are some helpful calculations consider that a miner basically turns electricity into hashes and creats tons of heat doing it.
https://shop.bitmain.com/antminer_l3_litecoin_asic_scrypt_miner.htm?flag=specifications
L3+ uses ~800 watts at the wall
http://www.rapidtables.com/convert/power/Watt_to_BTU.htm 800 watts = 2700 btu/hr per device. someone can step in and say whether this would be overkill for a miner. but your looking at a maximum of needing nearly 30k btu/hr in cooling for 10 L3+ miners.

Take care, keep cool !

I hope your not seriously thinking to cool down 10 units in an enclosed room by A/C alone. If your doing it by A/C at all in the first place your doing it wrong. You'll end up with as much A/C power to cool then as they put out.

Ill help you out:

1. Cut a hole in your wall
2. stick an attic fan to it
3. sip on your espresso

What to do in places with 84F or over 32C? Fan alone can't possibly work. Ideas?

Reading this thread and searching on line as well, I also seem unable to locate the specifics of how much heat each unit produces

I have 4 L3's on the way right now and my intention is to look at a small farm in the approx 100qty range in the next 6 months, part of the research is to calculate heat output and cooling requirements

Does anyone know if heat output has been tested or of a resource where data of this type is posted?

[dagarair]

how many watts?  watts x 3.41 = BTU output

[HagssFIN]

It is roughly 800W per miner with stock settings.

Measured with a Kill-A-Watt electricity usage monitor.

Ten miners - roughly 8kW.

This equals about 27300 BTU/hr.

Pushing air into the room is more effective & efficient than trying to exhaust it. Give it a try both ways and take temperature readings, youll be surprised. Good luck!

[dagarair]

800 x 10 = 8000 watts x 3.41 = 27,280 BTU / 12000 = 2.3 Tons of air if you want to cool it.

I am considering placing my 4 x L3's in my garage to assist with cooling and air movement.  I live in the Northern hemisphere and my garage in between the sun and my house so usually in the shade.

I am wondering about humidity, dust and -30* temperatures, as humidity, dust levels and temperature changes outside, how much of an effect will this have on the units?

Also If I use an air intake approach, I am concerned about intaking snow and/or rain, anyone have experience with the above?
