Here's a short vid of old setup:



To the point:

I need to build a small room to house 6x S7's to take care of the dB issue (Grandpa's not def.. yet!) and hopefully make it easier to take care of cooling (air flow control).



I decided to put up some walls in this corner of the room in the basement:



This way I can pull air in through the window, and exhaust it thru the soon to be bigger vent. + I'm going to setup some kind of "air-sluice", to be able to control how much air is exhausted inside (for heating purposes) and outside.



Dad hooked me up with some free wood: (LOL)



It's of course all wet (...), but this doesn't really matter as its a temporary setup anyway. And the miners will dry em up!



When I got back, grandpa(87) had already ripped out the vent, and taken off the window, he was excited!





Time 2 cut:





Todays result:







Tomorrow I'll finish the walls, aka. add wall boards like the one you see in the background of last pic. And try to figure out some kind of door.

I also need to make a box of some kind around the window, to funnel the air into the "room".



Anyone else doing something similar?

All suggestions/comments are welcome! So, I've been mining in my grandpa's basement since early 2013. This has been a win-win situation overall. He gets free heat (his whole house), and I get a location to host my miners. ^^Here's a short vid of old setup: https://www.youtube.com/watch?v=aJ_kJLGYxRQ To the point:I need to build a small room to house 6x S7's to take care of the dB issue (Grandpa's not def.. yet!) and hopefully make it easier to take care of cooling (air flow control).I decided to put up some walls in this corner of the room in the basement:This way I can pull air in through the window, and exhaust it thru the soon to be bigger vent. + I'm going to setup some kind of "air-sluice", to be able to control how much air is exhausted inside (for heating purposes) and outside.Dad hooked me up with some free wood: (LOL)It's of course all wet (...), but this doesn't really matter as its a temporary setup anyway.

Six S7's will suck a fair amount of electricity. I see a single outlet. I hope it's 240V with at least 30Amps.



Good question! What you see are 2 outlets, each on its own 225-230V 16A circuit.



225-230V X 16A = 3600-3680W



Each S7 rated at 1210W, ideally I shouldn't run more than 2 miners per circuit. I'm gonna try 3 anyway, might need to underclock. (I've run these at 3600W for almost 2 years ) The total length in cable from outlet to circuit is about 2-2,5 meters, and there are no other outlets/connections on the wire in-between.

Another option is I got another 10A circuit on the other side of the room I could run 1 miner on, so that puts me at 5. The last one could be hosted at a secondary location I got on hand.

Option 3: I setup another 16A circuit.



I am however a little more worried about the heat! There will be 2x 125mm air outlets with a 125mm fan rated at 400 m3/h, in a push configuration.

Ventilation will be trial and error! ^^



Edit:

On a positive note, the input air temp is now around 10C, when winter comes it will be -0 to -20C. That will be interesting. Good question!

what amount of power is the main breaker rated for ?



also try to blow HOT AIR OUT OF THE ROOM NOT IN then this will make the room pressure drop and it will suck cool air in from the other room or window in the room this is what I do and the room stays so much cooler.

Making a "vent shaft" from the window, to the bottom of the miner-room. This is where the fresh air is gonna come in to cool off the miners.

This will hopefully prevent snow from blowing in on those nasty days as well! I'm considering installing some kind of filter over the window to filter-out the dust particles. Dust is what killed my GPU-rigs, tho the S1's haven't been affected by the dust. I guess the ASIC fans are a bit more "heavy duty", compared to GPU fans.



One of the boards is becoming a door, so that I can access the room from the "hot-side" of the rack I'm placing in there.

The idea is to use plexiglass or something similar, to make the rack air tight, so that all the cold air are forced to go threw the miners.
