Here's a video I made today showing comparison of T-9 11.5 vs. S-9 12.0 variable frequency power draw at the wall. Uses more power, but runs cooler. At 210 VAC T-9 uses 1352 W, hashes at 11.5, highest chip temp 80C S-9 uses 1329 W, hashes at 12.0, highest chip temp 94C https://www.youtube.com/watch?v=yHJzo7A312cThanks for the video Jack. How strange the S9 is using so much more power than the stated specs on the web site. I think they quoted something like 1079w for the 12th S9 so that is significantly above the spec. Really looks like the T9 may be a winner then just based on the cooler temps and the power use looks like it isn't as bad as was stated in the spec for that unit. Good to know! The T9 may turn out to be a good unit! Please keep us posted. Well, in the first video I made I compared it to a 550 fixed frequency S-9 at 11.85 TH. The older 550 speed S-9 used only 1178 watts. I think when Bitmain changed to variable frequency they didn't update the specs on the S-9 |

I have just watched this miner. I feel very impressive with this batch of antminer.
I will buy it in next month after I got my salary.

Room temp was about 60 deg F |

Ah the time frames of Youth... A few miners with a few days of run time on them does not equal better reliability than a s9. Most folks have zero trouble with the s9's at the start (and minimal issues during its lifetime). Out of the 16 s9's starting from batch-1 that I have, only 2 bad boards to date. At least give them a week, preferably > a month and THEN make that call... Now better than the latest R4's -- based on my 1 bad out of 3, so far I'll give ya that one. |

Just lit up a pair of T9 on DPS1200 PSUs. Meter estimates 2850W for the pair and one-hour reading of 23.43TH between 'em for an average of 0.121J/GH.

We went ahead and purchased 15 R4's and 20 of the T9's for our own operation. We will keep you guys updated and post some pics when they come in hopefully this week!
T9's and R4's have been since Friday/Monday! Here are a few pics of them  http://imgur.com/a/vYxSj |

Stop buying industrial miners, running them at home, and then complaining about the noise.

At the time of purchasing the R4 was the only miner in stock. we picked up 10 of the 7.5's and 5 of the 8.7's. We were just itching to get some more miners/hashrate since before we bought these it had been roughly a month and a half since our last purchase. |

I received a T9 with what seems to be a defective fan. It starts hashing and soon it overheats. One of the fans does not go above 1900rpm.

My 3 T9s have been running 24/7 since the 23rd. No problems to report.
|
Keep calm and carry on mining.

Through week #1 today. So far so good. I wish i could change frequencies and fan speeds though.
Only complain was a "slow" fan wich was causing a miner to overheat. I had spare fans from a few S7 lying around, so problem was quickly fixed.

Funny, the tread is pretty dead because there aren't tons of us complaining about the high failure rate of our new miner (S9 or R4 thread anyone?)
Much like at a dinner table, if there's not a lot of talking the food is good!

I agree it seems like the T9 thread has been very quiet which really does imply that it addresses the S9/R4 issues. No one complaining yet so this is a good sign. But then again when the S9 first started shipping people were happy too.
So maybe another 30 days and we should probably have a good idea if there is going to be any fallout.
