May just have to pull the trigger again!
EDIT - Ah Steamtyme, my mistake, only a $230 coupon. Still tempting!

Hmmm, a grand, minus $250 coupon I got for buying first batch, for another S15 is tempting...

Dang, I knew I should had wait a bit.
I paid 1.2k USD for the S15 (27Ths Jan. 11-->)
and now they dropped the same batch price to 1k USD.
Fuck.

Here is 6days uptime numbers. Antminer T15.
My firmware is: Tue Dec 18 11:04:09 CST 2018. This unit is directly from Bitmain.

I received my first T15 this week finally. It has been up for about 2 days now. Here is how the setup went and my findings...
Which FW did your T15 ship with?
S15 up 12 hours and all is well! 
^^ Good to hear.
Now the question will become how many weeks/months the miners run before we start seeing issues

I received my first T15 this week finally. It has been up for about 2 days now. Here is how the setup went and my findings.
Out of the box the machine would not pick up an IP, had to do the IP report reset right out of the box but it immediately came up after that.
Initial test cycle took a long time, the machine did not start hashing until about 25 minutes after power up.
Normal mode results:
23.1TH @ 1560w at the plug.
LPM results:
20.9TH @ 1260w at the plug.
Other than the somewhat long boot times I am seeing (switching to LPM took another 15 minutes before it would hash) everything is running great.
Factory LPM specs are 21th max at 1260 and they NAILED IT. I couldnt be any closer to the advertised specs.
With all the other miners ive been testing having extremely loud 140mm fans its kind of nice to have a new miner with 120mm fans. Also helps keep my fan inventory useful going forward since I have hundreds of 120mm fans.

Great share sarcheer, more flex with the T15, S15 if you have active cooling or less than moderate temps.
Based on information available S15 and T15 in eco mode are very close in spec.

That's a bad sign. I have really high ambient temps in the summer. Lots and lots of flow, but I take 90+degree temps in the summer and exhaust 100+degree heat at times. This makes me think I have no hope if I buy these and try to run them through this summer. AC is not an option.

Temps for my T15 at 75ºF ambient intake temp, normal mode. You may have more overhead, temp ceiling-wise, if you go with the T15.
I am used to s9i at pretty hi temperature 85-90 in summer but the S15 is shutting down at 96.Temp. room is 20 degrees. It migth be to smal innflow of fresh air in the room as i suspsect low pressure. The fans are blowing in.

Well that eBay seller was legit, just got delivered tonight. Had I waited two days I would have saved $150 as the seller lowered his prices lol. Will post unpacking pics and my review in the coming days as work permits.
So some notes from my Antminer T15 setup experience:
Took approximately 6-10 minutes on average for my T15 to start up and complete tuning/begin hashing.
I initially had a network error, which turns out to be because the T15 does not accept pool addresses with the "stratum+tcp://" prefix. You simply specify the stratum address, e.g. stratum.slushpool.com:3333
Currently consuming ~7.5 amps at 200V, so around 1500W at normal mode, hashing at 23.5 TH/s.
This T15 came with the 12/18/2018 Firmware installed which may be why the start up sequence was quicker, or because its running in a 75ºF environment.
Also, my T15 HAS the top cover, so no exposed rails here.

Looks like middle boards are hot. Dead zone for cooling with two fans possibly?
I don't have one but I imagine the fans blow in? If so, maybe the middle needs a small case fan pulling at the back for short term till you dial in the machine for your racks/farm.
Start a support section thread if needed.

Been running 4 of S 15. Two in full mode. 2 of the 16 chip temp. show 90-92 degrees. The rest between 49-80. Airtemperatur 20 degrees. It shut down at 96. Any idieas?
Switch to low mode.
Show us the numbers.
Also before you switch.
Shows us all numbers for all four units.
You may have poorly glued/attached heat sinks.
I have had lots of s9s. With hot boards.
So a hot board is not unusual.
Seeing all four boards on all four units
On low and high power will help us to analyze what is wrong.
Thanks for answer.
No, since there brand new I havent opened them.

Possibly a couple of loose heat sinks? A couple of heat sinks out of alignment, disturbing airflow and creating dead zones of air?
Basically, have you tried looking closely at your boards to see if there is anything visibly amiss?

Not able to connect with SSH on my S15s T15s...
Is it normal?
That's a problem for people managing a lot of miners...
