I figure we are getting close to summer for most.  I know I am working on my summer mining area slowly.  Figured start a thread we can rate summer needs such as fan's or other equipment to keep your miners cool.

Lasko 2265QM 20-Inch Max Performance High Velocity Floor/Wall mount fan - http://www.amazon.com/Lasko-2265QM-20-Inch-Performance-Velocity/dp/B0073CQ9XA/


I have to rate this fan pretty I would say 4 out of 5.  I had a electric controlled fan I replaced, as if it lost power it did not turn on.  With this hardwired switch if there is a loss of power it starts back up when power is back.

It can be mounted on wall or use the stand it comes with.  Only reason I gave it a 4 was stand would be nice to have a little height adjustment.  I ended up sitting it on something to get proper height.  But very good fan was put in a good sized room and was able to push air from the 3 miners in there very nicely.  As I add miners to this summer area I should have a better test.

here the temp is still at 21° max, still good fresh air, nothing hot at the moment, i think it is still early to talking about the summer

miner can do fine for now, but i usually change their default fan since they are awful fan, and is so noisy

Within the next month I should have a lot more to add.  Over next few weeks I will be working on a new summer mining area. 

I will share results assuming it as goes as planned.

Tried another fan today - http://www.lowes.com/pd_416730-11292-SFDC2-600T_0__?Ntt=416730&UserSearch=416730&productId=4755305&rpp=32
Utilitech Pro 24-in 2-Speed High Velocity Fan


It is a medium sized fan at 24 inches.  It is rated very high cfm for its size: 7860.

I put one of these in area I plan on putting miners in.   Tested one out it does put out a heck of a lot of air.  I could feel it move air a good amount farther then other fan above.  And it still has a non-electrical switch that if power is knocked out it will come back on same speed.

that lowes fan has a good price  139.99

Two of them in the right spot can pull a lot of heat out of the room.

How many miners will you have ?

Yea It was a good price I got two and had 50 off 250, so was a very nice deal for the amount of CFM.

I currently have a little over 10k watts worth of gear.  I planned on going down from winter of 12k watts.  But I didn't go as far down as I thought.  

So now I'm working on getting a nice setup where I can put all in one room.  I have a 100 amp subpanal so have a decent amount of electricity just for miners. Winter was easy and had them separated but I will drain a lot of profit out of it if I used AC to cool them.

I don't have exact dimensions.  It's above a good sized two car garage and work space.   It could park four cars if you wanted to pull them in that far.   Good height on ceiling, they made it very steep which added a lot of room in the second story.   I need to walk to get dimensions it off it's a pretty massive room.

Sounds bigger the 20 by 25 by 10  that is  5000 cubic feet so your two fans can pull  about 15000 cubic feet .  You should be okay as long as  you are 2x fan power over cubic feet.
  What state are you in?
    Ie Texas, Alabama, Arizona , New Mexico all very hot.
  New Jersey, New York not so bad.

I'm in Kansas.  It's the house on the family farm (real crops sadly not a mining farm Smiley ).  But it give me a ton of room and also 200 amps in main breaker, and 100 amps in separate subpanel not connected to main.

It's been a good thing for mining.  But I will be glad to get some rooms back once I get this done and finished on new mining area.     And it's a pretty massive area on it I really need to measure or step it off sometime.

With longer ROI now I don't sell gear near as often as I once was.   This new area will allow me to keep my gear over summer (if all works out right) and hopefully have a little room for adding a machine or two as I would guess I will want more.

The longest part of this I think will be getting it's electricity wired. It already has networking going out to it.  It's going to start with 110's just as it's easy/cheap to do.  And hopefully get some 240 later on down the road.  It's a heck of a breaker box with 100 amp so lot's of options.

Is the breaker  box in the new building?

I assume  it is  please post a photo of it.

  240 volt is really easy to do.

1  30 amp 2 pole breaker in the breaker box if the breaker box has a pair of 120 wires feed to it.
1   30 amp plug
a  10 gauge romex wire a used pdu on ebay

and you are done.

I would consider them to be decent, not a super deal.  But it's in the 9 cents by time you tack on all the fees and taxes.

 under 10 cents lets you mine above power and other costs.  thread water is a big part of the game now.  then cash on the upswing.

With longer ROI now I don't sell gear near as often as I once was.   This new area will allow me to keep my gear over summer (if all works out right) and hopefully have a little room for adding a machine or two as I would guess I will want more.

The longest part of this I think will be getting it's electricity wired. It already has networking going out to it.  It's going to start with 110's just as it's easy/cheap to do.  And hopefully get some 240 later on down the road.  It's a heck of a breaker box with 100 amp so lot's of options.

Is the breaker  box in the new building?

I assume  it is  please post a photo of it.

  240 volt is really easy to do.

1  30 amp 2 pole breaker in the breaker box if the breaker box has a pair of 120 wires feed to it.
1   30 amp plug
a  10 gauge romex wire a used pdu on ebay

and you are done.

I will try tomorrow to get a picture.  It is a big box.  It's ready to have breakers put in it.   I still need to do some cleaning in second story.  Have 12 guage wire for the 110's and breakers.    It is a subpanal that goes to new building it has 100 amp going to it. 

I could use your advice on PDU I was looking at http://www.tripplite.com/metered-pdu-30a-208v-240v-0u-vertical-c19-c13-outlets-nema-l6-30p-single-phase~PDUMV30HV/ .   It appears it uses "NEMA L6-30P" plug.   What type of reciptical do I need for that?

I would truly appreciate your advice on what type of receptical you wired the 240 to that would work with most PDU's.

that lowes fan has a good price  139.99

Two of them in the right spot can pull a lot of heat out of the room.

How many miners will you have ?

Yea It was a good price I got two and had 50 off 250, so was a very nice deal for the amount of CFM.

I currently have a little over 10k watts worth of gear.  I planned on going down from winter of 12k watts.  But I didn't go as far down as I thought.  

So now I'm working on getting a nice setup where I can put all in one room.  I have a 100 amp subpanal so have a decent amount of electricity just for miners. Winter was easy and had them separated but I will drain a lot of profit out of it if I used AC to cool them.

Ac is a no go.   what size room will these be in?   20 by 20 with a high ceiling?

I don't have exact dimensions.  It's above a good sized two car garage and work space.   It could park four cars if you wanted to pull them in that far.   Good height on ceiling, they made it very steep which added a lot of room in the second story.   I need to walk to get dimensions it off it's a pretty massive room.

Sounds bigger the 20 by 25 by 10  that is  5000 cubic feet so your two fans can pull  about 15000 cubic feet .  You should be okay as long as  you are 2x fan power over cubic feet.
  What state are you in?
    Ie Texas, Alabama, Arizona , New Mexico all very hot.
  New Jersey, New York not so bad.

I'm in Kansas.  It's the house on the family farm (real crops sadly not a mining farm Smiley ).  But it give me a ton of room and also 200 amps in main breaker, and 100 amps in separate subpanel not connected to main.

It's been a good thing for mining.  But I will be glad to get some rooms back once I get this done and finished on new mining area.     And it's a pretty massive area on it I really need to measure or step it off sometime.   

 Do you have decent power prices?  8 or 9 cents?

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Thank you!  That reciprocal is great I was banging my head against the wall on what I needed.  And I love the price of that  PDU vs some of the others. 

I will get some pictures of box soon.   I will also see if i can find my measure to get dimensions.   Hopefully next weekend this project will be done if not mostly done.
