Title: HELP - My first Antminer S9 is reaching 81F ?????? Post by: Dragonizer on April 03, 2017, 02:13:42 PM Hi
Just had a new S9 from latest batch and the temps range from 59 -81f !! There is no way to adjust frequency, the temps on chain 2 are 71,74,81f Is this OK, it's in a cold garage, plently of ventilation ? Cheers Title: Re: HELP - My first Antminer S9 is reaching 81F ?????? Post by: HagssFIN on April 03, 2017, 05:06:55 PM Those are ok values and the unit is CELSIUS, NOT FAHRENHEIT. 81 Fahrenheit would be pretty cold temperature value for a miner, don't you think? ;)

Post by: HagssFIN on April 03, 2017, 07:23:51 PM The autotune frequency setting is chip quality dependant and for cooling there is an automatic fan control.
105 C is the high limit, below that and you're fine. Title: Re: HELP - My first Antminer S9 is reaching 81F ??????

Thank for the info, got another two on the way and need to find a way to 'rack' them. metal shelve them ? I just have the Bitmain PSU alongside the miner and the cables are TIGHT ! Cheers Hag |
