Title: BTU Output of L3+ AntMiner Post by: chipmonk1999 on July 15, 2017, 10:04:26 AM 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 Title: Re: BTU Output of L3+ AntMiner Post by: jasemoney on July 16, 2017, 01:55:16 AM 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 (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 (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 ;) ! Title: Re: BTU Output of L3+ AntMiner Post by: jstefanop on July 16, 2017, 04:28:23 AM 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 Title: Re: BTU Output of L3+ AntMiner Post by: pdpanzer on July 16, 2017, 04:38:03 AM What to do in places with 84F or over 32C? Fan alone can't possibly work. Ideas?

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? Title: Re: BTU Output of L3+ AntMiner Post by: dagarair on October 15, 2017, 05:54:25 PM how many watts? watts x 3.41 = BTU output
Title: Re: BTU Output of L3+ AntMiner Post by: HagssFIN on October 15, 2017, 05:57:43 PM It is roughly 800W per miner with stock settings.
https://www.youtube.com/watch?v=PPIlHbqms3Y Measured with a Kill-A-Watt electricity usage monitor. Ten miners - roughly 8kW. This equals about 27300 BTU/hr.

Give it a try both ways and take temperature readings, youll be surprised. Good luck!
Title: Re: BTU Output of L3+ AntMiner Post by: dagarair on October 15, 2017, 07:01:28 PM 800 x 10 = 8000 watts x 3.41 = 27,280 BTU / 12000 = 2.3 Tons of air if you want to cool it.

Give it a try both ways and take temperature readings, youll be surprised. Good luck! 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? |
