Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

What is the recommended Chip temp for S9?
Im currently running between 85-91C.

under 95 c is okay

over 100 c is not so good.

in-between 95c - 100c is unit to unit.

based on use of 20 units from June 2016 until now.

also room temps can be cold 10c or warm 35c

and inbetween.

Getting a couple S9's online, 14TH batch. Any way to adjust the fan speed and Clock anymore? cold basement and chips are 68-71. I'd like to turn fans down for noise and run chips around 88-92. I remember seeing a URL link to still access the fan and click settings, latest shipped FW does not have those options anymore.

Where did you get these from?

Ordered a couple months ago directly from Bitmain. I was the December batch, just received them yesterday. Tempted to sell some since going for over 5K on Ebay, but who know BTC could be 25k in a couple months

I got mine Friday, hooked it up to make sure it worked and listened to the wife bitch about how loud it is. On E-Bay now... The L3+'s she can deal with, but the S9 is just too loud!!

Yea, its loud. I'm trying to see how I can turn down the fan speed from 4200 to around 3200. My temps are low and miners in basement so its cold down there. Last winter I ran 3 S7's for heat and 3000-3200 RPM was fine and manageable noise.

You can always build a box with intake and exhaust holes and soundproof it.

I've seen that, but I remember someone posted a miner config link that still lets you adjust fan speed and clock settings....I prefer to do that

no go bro can no longer be done.

build a tunnel like I did
