Good plan. Use ur miners for heat in the winter reduces heating costs. It's like heaters that pay for their own consumption.
I TOTALLY AGREE with you on that one!!!  |

If your fan is blowing into the garage you may find it get quite warm in there.
Agreed. It gets VERY cold in the garage in the winter. 3 of our 4 bedrooms are over the garage. I've put brazilian rosewood flooring in all the bedrooms, living room and hallway. The floors in the bedrooms are especially cold during the winter. I was kind of hoping it would warm up the garage; which in turn would warm up our wood floors. I plan to add a "T" duct onto this exhaust fan in the Spring. One part of the "T" will allow heat into the garage and the other part will continue with duct to the outside. I can put an end cap on the part of the "T" that opens to the garage in the Spring. I figured I could hold off on installing the "T" duct until just before Spring. I'm presently looking for a small window air conditioner to install down low in the wall of the closet. I would run a hose from the drip pan of the window air conditioner to my HVAC unit's water pump that pumps condensation outside. Thought they could just share that pump that sends the condensation outside. |

 They seem to be doing fine in there for now. I'm going to be monitoring the temperature on them over the next hour. I do believe I will need another Hyper Fan and install another 14" x 6" vent when I get more miners (S4's). It is nice to no longer have 4 box fans going. It's much quieter now. |

What kind of heat load are you planning on putting into that closet?
It's actually what kind of heat load am I taking OUT OF the closet? Either or. It'll all balance out eventually.  I'm going to order a Temperature/Humidity meter to mount on the wall in this closet from Amazon. Probably order it this evening. I'm curious what temperature it will remain consistent at during the winter in this 122 cubic feet closet. Depends on how much power you're dissipating in the closet and the outside air temperature. If I read it right and you plan to have 11 S4s and 18 S3s in there, you don't have anywhere near enough ventilation in there. That's 20kW of power, and you're going to need way more air movement to keep temps down even if you have cold intake air. 720 CFM is a LOT of CFM's compared to the fans of the Antminer's. But yes, when I do have up to probably 6 or 8 S4's along with 16 S3's, I may need to add another Hyper Fan and another vent. We will know for sure after I have things in their running and a thermometer. It's really not. I have a pretty similar setup to what you are doing, though I don't have as much gear. https://bitcointalk.org/index.php?topic=519943.msg7331966#msg7331966The two 20" fans are these ones, rated at 6800CFM. The window's been closed in so all the air through the fans is fresh from outside. http://www.lowes.ca/portable-fans/utilitech-sfc1-500b-20-in-3-speed-high-velocity-fan_g1716654.htmlI'm pulling about 15kW, and seeing about a 20-25C rise in temperature from intake to exhaust with the two 20" fans. Thanks for the info!!! Sorry it took a while to get back. I went back to Lowe's again [For a 4th time today] to get some L-Brackets. You will see the two L-Brackets underneath the piece of wood you see the Hyper Fan mounted to. I've installed the 8 inch Hyper Fan:   I felt a LOT of air blowing out of the 14" x 6" vent on the bottom. However, it was blowing down to the floor. I decided to flip it upside down so the air blows up to the equipment when I put it in the closet. I also believe I will need to install one more Hyper Fan when I add more S4's. The next Hyper Fan I get will be a 10 inch. I will also install one more 14" x 6" vent going into the garage AND one more 14" x 6" vent VERTICALLY to the left side of the closet door entrance underneath the light switch. That should bring in more cool air from the recreation room. The air feels pretty cool already coming from the garage through the present one I have already installed. Those two (2) fans and three (3) vents should be sufficient... I HOPE!!! The reason I want my rigs in the closet is because I'm about to finish my recreation room. It's actually going to be my man cave with big screen TV. It's a 12.5 feet x 25 feet room. I have some french doors I need to install to the entrance of the recreation room. I have a big leather sectional that can seat 11 people to put down there as well. I want to make it look nice but the miners would interfere with watching TV down there. I believe the noise will be fine with everything in the closet. If anything, it will be like white noise down there. It will easily be drowned out by the sound system when watching TV. |

It's more of an experiment at the moment with 16 S3's [for now] and one S4 soon to come. I need to make approximately 0.7 more BTC to order it from Bitmaintech.com. Could be less than that if the price of BTC had not gone down the way it has the last 48 hours. I can easily throw in another 14" by 6" vent and another 8 inch or even 10 inch Hyper Fan. We'll see what happens with the 16 S3's with what I have presently after I get that Thermometer/Humidity Meter from Amazon. |

I'm curious what temperature it will remain consistent at during the winter in this 122 cubic feet closet without an air conditioner. The garage stays pretty cool during the winter. So, it will pool in cool air from the garage into the closet through the lower rectangular vent; then up and around the equipment as it heads up to the ceiling and out the circular vent with the 720 CFM exhaust fan. Remind you, the closet is 122 Cubic Feet (CF) and I'm hooking up a 720 CFM exhaust fan. 1.5 minutes into this video, this fan wants to blow itself off of the table. https://www.youtube.com/watch?v=0DkzX6ElX_4 |

Update: 8 inch circular hole cut out and starter duct in place...   Garage view: Two starters joining one another but without HVAC tape.  Put some HVAC tape inside to join the two starters and make it air tight so I don't have to put tape on the collar outside of the starter.  Still working... |

The 14" x 6" vent cover is on. Closet view:  I'm heading to Lowe's to get a 14" x 6" filter. I may have to cut something down to size to fit. We'll see... Gotta drink some coffee first to wake up! You can see where the foam insulation was trimmed out from the garage view. I have another 14" x 6" vent cover plate to cover this hole in the garage after I install the filter.  |

You been doing a great job on all that. Looks great and I'm sure it works great!
Thank you. You're very kind. I'm just slapping it up kind of quick when I have the time. I'm not worried about painting THIS closet. If and/or when we ever sell this house, I will dismantle it if the buyer likes and fill in the holes then paint. Who knows, they (the buyer) may want me to leave it the way it is and paint it. I'm remodeling the entire downstairs. I still need to put grout in the tile in this closet and another closet downstairs. |

^ Do you ever stop long enough to sleep? Better slow down or you're gonna get a ticket I get about 6 hours sleep on average since I started mining. Yes, it is the same room (closet) downstairs in the Recreation Room to the right of where my rigs are presently set up. Please ignore the shoe racks, the mess, etc... That stuff will not be in this closet when I'm finished and everything will be cleaned up.  I'm thankful the electricity costs will be VERY manageable during these winter months to allow me to buy S4's more often till I reach the eight units I'm wanting to get. I may also get Alabama Power to run me a second 200 AMP meter to the house to put more S4's in the garage on the shelves you see in the pic above. I'm moving it out to the garage when I've finished this data/mining closet. OR I might install something else on my roof for extra power. I'm making another post devoted to that next.  |

Who knows... What I'm doing may give someone else ideas. Maybe better ones. If so, please share... My mining/data closet is coming along slowly but surely. I've put up shelves that are 20 inches deep. However they are 3 inches away from the back of the closet to allow room for power cords, etc. You can see this in the 2nd picture. You also see a 14 inch x 6 inch rectangular hole I've cut out in the bottom corner going into the adjacent garage. I've sprayed a foam insulation that hardens up over time. I need to trim it after it hardens. I will be putting vent cover plates on the garage side and inside the closet to cover the rectangular hole once I've trimmed out the excess foam. I will also put a 14" x 6" filter inside between the garage and closet vents to keep dust in the garage from coming into the closet. I've also put several strips of wood going across for extra support (bracing). It is 43.5 inches from right to left and 13 inches between each shelf. The existing top shelf is only 16 inches deep. I'm leaving it alone. S4's are approximately 5.5 inches tall (top to bottom), 17.25 inches wide and 17.02 inches deep (front to back). Being they are 5.5 inches tall, I can stack two (2) S4's on top of one another and still have 2 inches clearance from the shelf above them. I designed this so that four (4) S4's will go on the bottom shelf and four (4) S4's on the next shelf above it. The four S4's on each shelf will take up 34.25 inches of the 43.5 inches width of each shelf. This leaves me approximately 9 inches space between each double stack of S4's on each shelf. That extra 9 inches can be used to double stack two S3's with PSU in between the four S4's on each shelf. Fourteen (14) S3's will be on the 3rd shelf from the bottom. Not sure what I will use the top shelf for (4th from the bottom). I might use it to place my 48 port switch. Still thinking about it. This has been planned out to also put 3 more S4's stacked on top of one another on the floor in front of the 14" x 6" vent I just installed.  Just a pic showing the 3" space from the back of the closet wall to allow room for cords, etc...  Then next thing to do is cut an 8 inch circular hole near the ceiling and install duct work going to this 8 inch 720 CFM fan I purchased. The closet is 122 CFM. So, this fan with variable resistor should be PLENTY of CFM to suck cool air in from the garage through that 14" x 6" vent up through and around the miners into the 8 inch exhaust fan near the ceiling. The reason I went with this 8 inch instead of 6 inch or 4 inch is to make sure I had plenty of suction to pull out the heat. I wanted the re-istat (variable resistor) to turn down the speed of this bad boy so it would not be too loud. Also, having the larger fan with re-istat turned down allows the fan to last longer than a smaller fan turned up at too high of a speed to contend with getting all the heat out.  More pics to come when I'm finished. |

Don't take my last response literally, it's just a phrase. Of course you could be more wrong.
np Yes, I could be more wrong. |

If you have EVERYONE's CPU on the guild that COULD be a lot of hashing power if combined.
No it wouldn't. Please check your numbers. 10,000 of the most powerful CPUs today amount to about one S3 which is 440GH. For a pool with 13,000,000 GH, do you honestly think the pool operator would risk his reputation for that much more? What I'm mentioning is NOT to continue accusations. What I'm mentioning is merely to prove a point. MacBook Pro 17" Early 2011 2.2 GHz Intel Quad Core i7; meaning 2.2 GHz x 4 cores = 8.8 GHz 450 divided by 8.8 = 51.14 MacBook Pro 17" with i7 2.2 GHz Quad Core chips Most PC's and Mac's today I would say average around 2.2 GHz x 4 for 8.8 GHz but we will use my 2011 model Mac to be conservative. If you had 10,000 computers with 8.8 GHz average, that would be equivalent to 195.5 S3's; NOT ONE as you say. Also, if it took 10,000 CPU's to equal 1 S3, you would be saying EACH AND EVERY CPU in each and every computer [10,000 computers] is less than a quarter (.25 cents)! That is FAR from the truth. BM1382 has achieved 15.75 Gh/s in hash performance in each chip: BitMain BM1382 chip specifications: - Process Node: 28nm – Package Type: FCQFN-56 – Packaged Chip Size: 8mm x 8mm – Number of Cores: 63– Core Voltage: 0.75 V – Core Frequency: 250 MHz– Hash Rate: 15.75 GH/s 250,000,000 Hz (250 MHz) - Core Frequency x 63 Cores (processors) 15,750,000,000 Hash Ratemultiplied by 28 [63 core processors] = 450,000,000,000 (450GB) Total Hash RateThe new Bitmain Antminer U3 uses four (4) 1382 chips [4 x 15.75GH] for a total of 63 GH/s http://www.coindesk.com/hackers-hijack-retailers-showroom-pcs-cryptocurrency-mining/Also, if it took 10,000 computers, as you say, why would hackers even bother hacking these retail stores for dismal profits from mining? The reason is because it does not take 10,000 computers to make one S3. It only takes approximately 50 computers to make one S3 but that is being conservative. It may only take about 48 computers. I challenge anyone with a PC that has a QUAD CORE PROCESSOR to mine with their CPU for an hour then multiply their hourly average hash rate x 51 and see if it is somewhat close to one S3. Well, you might have to multiply it by 58 cause Slush always shows a little slower than what my rigs say. You might see you have to multiply times close to 200 to get close to 450GH/s. If that's the case, then it takes approximately 200 to equal 1 S3. You could not be more wrong! i checked with my buddies PC. You're right. I couldn't be MORE WRONG. |
