Finally, the replacement miner for poor, departed R4B4 has arrived in the ice mines at Hoth.  Took so long after multiple delays I hate to even think about it, but at least I've increased my hashrate by 50% so that's a plus. 
Mine on! 

There's always a silver lining! Good job!

I have 3 S7s that are in varying stages of swan songs that I'm trying to replace.  My hosting site is full so I can only replace; can't add new until they have expanded their capacity.  One of these S7s will be replaced in early February and I can't wait.  I can't seem to buy anything anymore so I don't know if I'll ever be able to replace the other 2.

What are they charging these days for hosting a S9?  and does that include the cost of power?

I have a location that I can use for hosting, but with a max of 200 amp 240 Volt service.  I might be able to get higher service, then it starts to get into commercial rates for electricity.  Looks to work out to 22 S9's can be run there.  I would be able to have a fibre connection to the location as well.  150 Mbit symetrical.

My total host fee works out the same as $0.08 electricity.  It was costing me $0.10 at my house and the noise and heat was brutal.

So 1100 kWh X .08 = $88.00? is your hosting fee?  a month?

edit: however, it only protects from spikes outside the house, it does not protect against surges that happen inside the house.

No.  It protects from all types of surges.  Even those rumored to be generated inside - for a long list of reasons.

Start with the most obvious reason.  How many appliances have been replaced today?  What damaged less robust appliances?  What protected GFCIs, dishwasher, clocks, furnace, recharging electronics, refrigerator, modem, LED & CFL bulbs, AC powered telephones (ie FIOS), garage door opener, TVs, and the most critical items if a surge existed - smoke detectors?   All those are suffering damage if internally generated surges exist.  Why not replaced daily?  Because internally generated surges are myths - intentional lies - generated to sell protectors that (otherwise) do not claim effective protection (such as APC).

If internally generated surges can damage those other appliances, then near zero joules in an APC are first to fail.

No protector does protection.  Not one.  That 'whole house' protector is effective because it makes a low impedance (ie less than 10 foot) connection to single point earth ground.  Then all types of surges - even a destructive hundreds of thousands of joule surges - are harmlessly absorbed outside.

For some reason, too many want to believe a protector must be between a surge source and its victim.  That implies a lack of basic electrical knowledge.  A surge does damage because it is hunting destructively for earth.  If any path to earth is not destructive, then all adjacent devices are not damaged.  What is a lowest impedance path?  That connection to earth (either by a hardwire with no protector, or by a properly installled protector) defines protection.

Earth a 'whole house' protector to do (more numbers - this time from the IEEE) 99.5% to 99.9% of the protection.  But, always, and again, a protector is only as effective as its earth ground (which obviously is not a wall receptacle safety ground).

...
So 1100 kWh X .08 = $88.00? os your hosting fee?  a month?

Officially it is $65 per kW per month (measured kW and not estimated).  With 9 S7s, 2 A721s, and 11 S9s it works out to $0.32/TH/day or $0.079/kWh.

Edit:  If I can get all of those S7s replaced with S9s or some of the newer A8s, my hash rate would go way up with little to no increase in hosting fees.  That's the goal but damn it's become nearly impossible to get new equipment from anywhere!

Edit2:  As you work your way through the numbers, all of my S9s range from 1290W-1520W and my S7s range from 1210W-1470W.  Both of my A7s are 1000W each.  There is a lot of range in the power usage of this equipment and there is no perfect answer but after 3 years of paying this host, I know how much it costs.

Heh those block fees must be getting low - pool payout for 505456 confirmed early again (about 15mins ago)

I'm surprised it took this long for someone to pick it up

[Thrash]

I have 3, one of them had the issue of intake fan higher than exhaust. I noticed that where the fan power supply plugs into the board was switch on the one. Powered down, swapped the supply plugs and fixed the issue. Also the many different fan brands have different power ratings so different speeds as well.

Thanks for the info. I will check that, could be a quick fix!

That is exactly what I found. The wiring was switched opposite of the other units. I did not have time to shut it dow nand switch it tonight but probably can tomorrow. Will post if it makes a difference on temps.

Yes, just noticed it was confirmed in my core wallet.
Nice to get a payout a little ahead of schedule.

MINE ON!

[AerialGopher]

The payout confirmation was just clearing the way for the next block in 4.32 hours

Guys, I have a 13.5 Th/s S9. But since I changed settings to sg.kano and shut the window of the balcony a little bit it's now always over 14 Th/s. Temps are 67, 60, 60 and GH/s avg is 14,008.

Is my miner doing too much and killing its longevity or it's completely normal..? I used to keep the balcony window wide open and temps were like 60, 50, 50 or something like that and it always hashed around 13.5 Th/s. Kano.is website is registering my miner's hash rate at around 14 to 15k.

Thanks guys.

Nothing to worry about.. you're fine.

Sounds like a good problem to me. I have one S9 that always runs hotter than the others. It never gets below 70C but seems plenty happy. It has a Nidec fan, the rest have Y.L. fans. I think I may change out the fans before summer and see if it helps.

Mine on!

I am looking to keep a couple spare fans on hand - just in case.  But Bitmain wants 15 USD per fan, and 20 USD to ship 1, or 30 USD to ship 2.  Yet I asked them if they could put in the two fans if i ordered them into my order of the A3 that I just bought...  and no response.  Then they shipped out the A3 without a PSU.. at least I have my spare PSU so I can at least use the thing.

I just noticed tonight that on all of my other unit the fan where the air comes out runs faster than the one where the air goes in. The one that runs warmer is just the opposite, the exit fan is running slower. I do believe that is the issue.

Typical Chinese Quality checking.  I checked on the two that I have in my office ( YES LOUD) and the fans are connected different too.  I will have to check on the other ones later.  But this one that looks to be the wrong one, is the one running hotter and is a 14.0 TH unit.  The others are 13.5 Th

Thanks for pointing that out.  I would never thought to of looked at that. I TOTALY trust made in china stickers!  
No Offence to the Chinese community....  just sometimes shortcuts that are taken cause a lot of problems.

Is a power off required? or can I switch them real quick without power down?

EDIT:  Nevermind.. They are hot and get hot faster without a fan..   WHY did I even think I could do it while it was on  hahah

[Jeremiah1610]

Power down, doesn't take 5 mins, takes out the risk, and with 5nd it won't matter much. I feel you though, I hate to shut them off as I'm still ramping up. My geek friend said the fans could control more than we think. Just safer.

[AerialGopher]

I checked mine, the one that runs higher temps and the one that ramps up and down are connected with Exhaust fan to FAN 5 ( Second connector from edge )


OK Lets vote on the fan wire locations - Because I have 3 set up one way, and 2 the other way. 
Indicate where your exhaust fan connects to on the board.  Is it closest to the outside edge, FAN 6 Connector? Or is it Connected to the FAN 5 connector that is second connector from the outside edge.

Just moved my machines over to Kano. I was looking through the pool stats, why did the PH rate nosedive in November? Many people must have left the pool or one really big user.

2 really big users.
You can see why at the end of October

Just checked the fans in my two S9´s and both exhaust fans are connected to the FAN5 connector. No problems at the moment with the fans ramping up and down.

Thanks man, gotta check a couple of S9's that coincidentally I was cleaning yesterday and didn't check how the fans were connected.

By the way, one of these fans is reporting >30.000RPM     http://tinypic.com/r/4g6f5e/9

That is one HARD WORKING fan!

[nazzer]

A couple of blocks overnight would be nice, Kanopool.

I promise I wont check for the next 12 hours ...

[Thrash]

It would be nice to get another block before the diff change.

Mine on!

[overcon]

I have .09kwh here in nc.

I have alot of room for more but would like to get thr roi on what i have currently.

I can host some though.

My power is .08 here in New Mexico!
