Chip Temps on my Antminer T9 are normally between 77c-87c degrees on all chains, but now chains 4, 13, and 14 show temps up to 145c!!! All other chains were normal (80c-85c) and all hashrates were normal.
I've been monitoring this over several days and temps on these 3 chains bounce all over the place. I took some screenshots that showed:
133c @ 1:09AM
85c @ 1:22AM
104c @1:29 AM
It went to 141c, 145c, 117c - all in a few mins between checks. As of the last two days, the temp on these chains is always high (110c - 145c) but jumps around within that range. The miner itself feels fine.
I've read the miner should shut down above 115c, and I don't see how it's possible that some chips could truly be at 140c while others are at 85c. My kernel log doesn't seem to indicate any temperature sensor failure...so I'm just at a total loss.
Do you think these chips could truly run that hot, or is this a faulty temperature read?
