Gotta love natural Canadian cooling.

And it isn't even winter yet. If you're wondering, temps are showing 0 because S4's temp sensors don't register below 20c.
Your HW Error is rather high.. and do you realise you have have a X on one of the chips?
Hard reset for that. I had one and a soft reset just makes it worse

Talking about that... my chain 1 goes offline after about 1-2 days running, sometimes in a matter of few hours. GUI will be reporting as if nothing wrong. You'll only notice when your hash rate at pool end drops. You can also look into the casing via the fans, you should be able to see 4 red leds if all chains are running. Was thinking of taking the S4 to a host but with me constantly having to look to see if there is 4 red leds, not going to be possible. Plus having to hard reset when you get "Hugs & Kisses".. makes it even more impossible to have the S4 hosted.
Could it be a firmware issue or hardware?
