I searched but there are sooo many pages
What are the temp limits ?
Based on bitmain installation guide:
Chip max temp 115
Board max temp 80

So:
The board max of 80 means shoot for under 75
The chip max of 115 means shoot for under 105
Based on what I see for chip temps with a PCB temp around 70 I would think the chip would go much higher than 115 with the PCB at 80.
