Mining room cooling issue.

[CJGoodings]

Pretty sure a inline fan would be sufficient, inline would be a little over kill if the opening of the duct is right behind the ants.

[CJGoodings]

Wait wait... what kinda temps are we talking about here?

[Skaterdiejosh]

It's a exhaust fan pulling the hot air out of the room. You just run the ducting to behind the ants because thats where all the hot air is. Im running 8 antminers and not over clocked and the room gets into the high 90"s without the exhaust fan. And the inline exhaust fan has a lot more cfm of air flow then any open air fan and it dont use all that much more power for a 4 inch one ...

ding, ding, ding!  just had a moment of realization.  I overlooked the obvious; the dryer room has a exhaust vent built-in for the dryer!    I'll put a fan on the ceiling and run the duct work down to the dryer exhaust and voila! the hot air is removed from the room.  Thanks for all your inputs.

I have a room that is about 8'x8'x11' which serves as home to my 6 Antminer S1's.  The problem is that the room gets quite warm when door is shut.  If I leave the door open, I will most likely annoy my roommate with the noise.  Any way for me to keep my miners cool and not annoy my roommate?  I was thinking about cutting a hole at the bottom and top of the door but I wonder if that'll be enough.  If the room is very warm, it's obviously damaging to the miners right?  The room doesn't get hot enough to start a fire or anything(obviously) but it feels like the middle of summer when the rest of the apartment is cool.  I have my miners unplugged for the moment till I figure out a solution.  Smart inputs will be appreciated.

two ways:

1. Pull off those cheapo fans and spend some money on quiet fans to replace them.  Try http://www.quietpc.com/casefans

2. Convert them to water cooling.

Likely your third problem is that you're going to be maxing out your 15A circuit too. My guess is that the next power supply you add is going to tip the load and trip your breaker.

As far as home cooling is concerned, you need to create airflow. If you can, open two windows and place two box fans into the windows. One bringing in air, the other as an exhaust fan pushing the hot air out. Also remember that cold air sinks and hot air rises.  To help the process, you can also put in insulated ducting from where your miner exhaust is and then the other end of the duct out the window. Another option is room-based AC unit, but you have to be careful with them. They usually have an condensation collector that fills up, they also pull moisture out of the air and static discharge will rise in the room. So don't touch your miners without some ESD protection.

The other option is to put the miners in a datacenter. Between the improvement costs you need to make and that you're probably going to run out of power, you may want to consider getting a cabinet. Lots of cold air, reliable power, and room to grow your farm.

I'm running the miners on the 50amp washer/dryer circuit.  No way would I run all 6 Antminer S1's on a 15amp circuit; it would probably trip the circuit breaker or start a fire.  I've read that 15amps can support 3 Antminers and 50amps support about 18.  I definitely did my research beforehand.

tell you room mate to get on board the train. feed him a little BTC watch his eyes get big and then show him how to buy a U2. then tell him how much more and how much faster you are able to mine. if all goes well and he takes the blue pill or the red pill or whichever on it is then it could snowball into a full blown mining operation and you guys rent another location to build your farm. BOOM business partners, mad cash flow, get the khakis, get the chicks and no more room mate. That was the goal right? Get rid of the room mate?

or you could be like bro i'll give you one percent to ignore all that noise.

If you cut a hole in your door. The noise will also get out.

How do you convert the dryer's 240V to 120V?

Your power supplies will be more efficient on 240V, so stick with that.  You can switch out the receptacle for one that will mate with a 240V PDU twistlock connector.

but this will burn my machine because my machine is 120v

i'm not using the 240v twist socket.  i'm one the socket next to the 240v socket. I believe this is the washer socket that is on the same 50amp circuit. If i am wrong about this, it would mean that the socket is run on the 40amp circuit meant for the kitchen, which is enough. My apt has a 50amp circuit for washer/dryer room, 40amps for kitchen, 20amps for living room, and 15amps for bedroom. If I decide to increase my mining operation to anything more than what I have now, I should probably hire an electrician.

[iglasses]

Tell roommate you are getting rid of the miners to make room for your new hobby...beekeeping.
Leave web browser open with order for 10,000 bee 'starter kit'.

Profit.

By twist socket, do you mean a NEMA L15-30?  if so, you can get a power distribution module used for mobile film and theatrical production.  some modules have a pass-through plug to the dryer.

rack mount ftw. moar power

AFAIK these connectors are rated to 30A so you may want to double check the ratings; washer may be on its own 20A circuit?

I bought a floor model portable ac unit from searsoutlet.com for $79.99. I had to fabricate my own exhaust hook up as it was missing. Cost me about $25 in parts at homedepot. I blow the cold ac through the intake fans. Problem is the damn thing uses 950w just for the AC. I will probably only use it in the summer when its 100+ degrees here in Texas.

I got ahead of myself and made a bad assumption; the socket that I am on is not 50amps, it is 15amps.  I made the assumption that because it was next to the dryer socket that they were on the same circuit but that was proven wrong when I tested the circuit breakers today.  I'm going to have to split up my Antminers and have them in different rooms so that I don't overload any one circuit.  I would like to utilized the actual dryer socket but as of right now, I don't know how.  I am much more safety conscious nowadays and am glad that I checked my circuit breakers.

Ok here's what you do since no one else has any better ideas besides killing or kicking out roommate lol !! I've set me up a few grow rooms for "friends" befor .. Buy a 6 inch can fan from your local hydro store . Also get the ducting and cut a hole in the ceiling in the room or closet. Keep the hole so you can put back the drywall if you ever need too. Have the fan pull the hot air from right behind the antminers..  This will solve your problem and the room will become half the temp it used to be ...  Good luck .........   A 4 inch one might also work for your purpose and use less power ...

I have a similar problem with heat/wife, I have a 6inch wall fan arriving shortly so I will update on its success after it arrives.

If you can get that ducting out ur window it saves on cutting your ceiling   pvc ducting is cheap as chips, if you use foil, make sure its secured away from those miners.

Personally I would take the mummy route.. but what to do with the kids ?

[Gator-hex]

Haha, if you think the noise is going to be a problem wait until the room-mate gets their share of the electricity bill.

The answer is to turn your miners inside out and put larger quieter fans directly on the heatsinks then leave the door open.
Here's a video so you can see how quiet this makes them: http://www.youtube.com/watch?v=VOyrCut0y30

[ElGabo]

I have a fan for 22000 air m3/hour. Thats enough.
