Coupon donate success!  Enjoy.

Hi Miners!

I would like to buy an S7. May i ask someone to send a coupon?

thanks a lot!

haha, good one.  EDIT: celsius not calculus.  haha

Maybe if you stopped doing calculus on the miner, it will run cooler??? 

Yesterday i purchased a Batch16 S7 with a second FAN thanks to your coupon 
As sson as i get it, i'll post the performance with SINGLEFAN usage and DUALFAN usage

Has anyone purchased and received the new ANTMINER S7 BATCH 16 with One Fan?  If so, let us know the stats on this machine, especially temps. 

I have found that the batch 12 run about 10 degrees calculus hotter than previous models.  Does anyone else see this same condition?

You do not want to donate 

Thank you very much!!! I bought one already with the first coupon i got donated, with yours i'll buy the second one next week 

I sent you one, happy mining

I live in a very low humidity area. I run a 3200 cfm swamp cooler in the front while venting out the back. Works very well and my humidity in the warehouse sits around 23%.

I am exhausting hot air from 2 S7's through insulated dryer tubing attached to a 20" box window fan running in reverse out of one window.

The other window has the window AC unit in it running on "High Fan" now and not using the AC condenser blowing the very cool air directly into the intakes and and on the power supplies.

I live in a weird climate where I can just open the window 6 or 8 months out of of the year and pull in air below 60 degrees straight to the units at times. But Then I have to worry about rain/sleet and snow coming at unpredictable times out of nowhere. Storms can come out of nowhere around here in minutes. Thunderstorm one day(night), snowing the next.

One day it will be high 70's to mid 80's during the day and go down to freezing at night.

As spring and summer roll on in, I can can get mid low 100 daytime temps in the miner room without the dryer vents. I also don't have to be here 24/7 make adjustments to my cooling system.

Also, that way I am also able to OC the units close to a a hundred C above default while my board temps are still in the mid 50's to low 60's and the room remains pleasant.

I am also able to isolate the central AC from that room.

I have only been doing this set up for a couple months and it seems to lower my electric bill by about $50 or so a month.

I'll give it some more research time before making any final decisions.

AC is used when you cant/dont have free flowing air. ie in a basement not near any windows or where the incoming air is to warm.

your right in that controlling heat and good air flow is best but sometimes that isnt possible.

Out of curiosity, why are you guys using air conditioners to cool your mining rigs? I would think it is much more cost effective to exhaust all the discharge heat and maintain good air flow

Thank you. I will check into the details before buying anything! 

With a unit that old verify it runs on the R-134 coolant before filling. I'd  recommend the can that also contains compressor oil.

Yeah, I've got a blade in each of my units that normally runs a C or two hotter than the others. I think (and have read) that's it's just an issue with the placement of the temp sensor inside the miner.
Good luck.

You may be right.
The windows unit is at least 12-15 years old but was rarely used and has been under the house for the last 10 years approximately completely unused.

I may go to a hardware store and get one of those things that will allow you to recharge/top-off the coolant in the AC (If this unit allows it. I will check it out tomorrow.) It could certainly have leaked out after all those years. But when the unit is operating normally without any icing, it puts out some amazingly cold air. It's an old Kenmore 5,000 something BTU unit.

Thanks for the idea!

You might also have to consider that your AC unit needs repair. I have seen AC type units that will "freeze the coils" when the refrigerant inside is "low". I don't really understand why that happens, nor the specifics, but I had a de-humidifier that had lost some refrigerant, and it would "ice up" even when the temp was above 70F. It wasn't cold temps that mattered in that case.

How new is your AC unit?

I found it completely counter-intuitive that low refrigerant could yield ice on the coils, but some Google research may explain it better. It's still confusing to me.
