antminer s9 One board very hot

[Maus44]

Cleaned all my antminer s9's yesterday using pc duster. Today one of the miners showed a chip temp of ~145 . I took that unit apart and there was some dust that I must have missed when I cleaned it yesterday. So I dusted the hashing boards and put it back together.. one of the chip temps is still ~145 but it is hashing fine.

Is my miner about to fail or could this be a false reading? Is there anything I can do to fix this?


Thanks

Don't panic...happens rather often.....if suspect board is hashing and other board temps are fine ....it is also probably fine...

I have a few boards do the same....Reboot after a few hours and they usually return to normal proper reporting...
Probably just the themistor sensor getting spoofed or picky or flaky
I have another board with flaky temp reporting for months but hashrate is rock steady.

Could also be problem with controller board...swap board's positions to eliminate if it's board or PCB related.
