people are being surprisingly nonchalant about it.
...I woke up at 3am this morning and at first could not figure out why.
then i heard a tiny noise coming from s7 (much less than s5)
;run to it, Internet is down ("internet not working well" situation)
miner is still doing something and fans are on very low, and air is coming out quite hot.
Thankfully, I had a Vornado fan blowing into intake for such situations and to help with cooling, so no critical overheat occurred.
Internet came back within 2-3 min and it was back to hashing.

all i am saying: beware and try to adapt. i can practically guarantee that it WILL happen in large hosting because usually service guarantees just 98% uptime.
If service loses internet, but power is on....

I'm curious...  Did you already have the October 23 Firmware update on this rig?


no, i didn't, as i usually wait a few days-this saved my hide a couple of times when upgrades were bad.
upgrade might help, but it seems that it is a problem that migrated from s5 to s7 and if it was easy to fix, they would have done it long time ago.

I have a question about manual fan speed setting.
If you set it to 90% does it stay 90% even when the internet goes out? Or does it cycle down and back up to speed?  That would be great if it just kept up speed.

Damn good idea.

I'm not willing to disconnect the internet to find out.  I would have to take one rig away from all of the others to listen.  Why?  Because without internet, we could not log in to it to find out.  We would have to be next to it away from all other rigs to listen to the fans.

I'm not willing to disconnect all 9 of mine to find out.  I don't have 240 anywhere else in the house with a NEMA L6-30 outlet.  I suppose I could do it with my corsairs at another location.  I'm just not willing to disconnect to find out.  I'll see if someone else does it first.  If they don't, then I will.
