Help please.. I hope I'm posting in the correct thread.
I have a Antminer S7-F1 4.73th (Upgraded to 2fans), what does it mean if I heard one of the fan or both fan speed (I'm not sure) went up and down, up and down. and it showed a very low hashing speed. and cold temps? but it went back to normal when I rebooted it. Does it mean a problem is on its way? Will it cause fire and burn? Do I have to worry?
Your professional advice is appreciated. thank you.

Fan cycling is part of the restart process and can be triggered with a temporary loss of internet connection. There is no issue and nothing to worry about. |

There is no issue and nothing to worry about. thank you for your reply. the miner was hashing normally for days, then i got a warning from my miner monitor (awesome miner). that one of my miner is hashing too low. there i noticed the fan is sounding like a servo adjusting voltage on an automatic voltage regulator... sounding like when you accelerate and stop a remote control toy car... No worries? please be sure.  |

No worries? please be sure. Yes. On the reset cycle they make it go up and down in fan rate to clear dust. |

Please somebody help me!!! What name of this connectors and where can I buy it?  They don't have an easily identifiable name but they'll be readily availble on ebay under "9x2 pin pcb socket" or similar. Might have to play around with the keywords to find it. |

Has anyone ever tried to use another fans to reduce the noise? I thinking about use some Prolimatech Ultra Sleek Vortex 140mm, I know that its 166 m³/h instead of the 188 m³/h from the default ones, but I'm talking about 18 dBa at full speed! |

OK I've upgraded my FW to may23rd release, we'll see if it makes a difference (no x after 20mn...) System
Miner Type Antminer S7
Hostname AntminerS71
Model GNU/Linux
Hardware Version 3.5.3.0
Kernel Version Linux 3.8.13 #22 SMP Tue Dec 2 15:26:11 CST 2014
File System Version Mon May 23 15:57:10 CST 2016
Cgminer Version 4.8.0
Uptime 22
Load Average 0.99, 1.06, 0.78 -------------------------------------------------- still no x after 12h \o/ 3d10h29m15s => still no dead chip !! Woot, I'm really happy with the new FW ! May I ask... how did you choose the right firmware for your device? how do I know which batch of S7 i own? |

batch doesn't matter, only a 1 or 2 fans version matters for the firmware you choose  |

Just started with an S7 with a single fan. TOO LOUD, and there is an annoying whine sound. I like the enclosure ideas, but wanted to try quieter fans. Ordered 2 Noctua fans ( http://noctua.at/en/nf-f12-industrialppc-3000-pwm) for push-pull config. I see there is a second 4 pin connector on the control board. My question is, does anyone know whether I can just plug in the new fans and the firmware will control them properly? Or should I just wire the fans straight into the PSU? Thanks, |

Thank you zOU!
Just what I needed. Especially enjoyed the warning not to attach the fan the wrong way so it pushes air into your miner. That would be both tragic and hilarious.

Dogie, can you give me the distances from the edges to the nearest heatsink? Thanks. |

I suppose a PC Power & Cooling 1200W PS is not sufficient to run an ANTminer S7 at the standard frequency?
|
Did I say something helpful? Funny? Or you just want to help a poor public servant out?

1st post states that power consumption is 1300W. |

MY s7 shows no hash. All the chips are normal. Temperature is below 80.  |
