i have actually just noticed that one of my chips on the 1 hashboard is about 158C its only one chip and im just wondering is this chip just going to burn up the board or is there somehow a read error on this board where that cant be possible?

Check the hashboard physically it might have a loose heatsink you can fix them by using thermal adhesive or thermal glue or hire someone to repair the hashboard it could be a dying chip or it needs a bit of resolder due to cold solder joints.

Check the list of repair centers from this link below and look for near repair centers.

Do you have any idea of the maximum chip temperature for a 1166 Pro 81TH; on the Canaan website we can only find the user manual for the 1146 Pro and the maximum chip temperature is 85°C

Thank you

If you go directly on the detail page of 1166 pro under documentation you will get the 1146 pro manual that's the only manual they have for this unit.

So yeah the maximum temp of each chip is 85°C more than that the hashboard will be disconnected automatically and you will notice the drop in hashrate.

I tried aging using FMS once before, but how long does that procedure last? It was quick, is that normal?

Maybe I should use the command [{"command":"ascset", "parameter":"0,aging-set,1"}] instead of clicking on aging?

I don't know if it will save permanently but based on someone's experience that I heard it after the miner restart/reboot the issue goes back again but their issue is related to fan speed command, not on aging. So why not try to send that command again or use the aging button?

That command above or the aging button is automated tuning you can also manually play on the parameter like this command below

Code:

[{"command":"ascset", "parameter":"0,aging-parameter,60-537:562:587:612"}]

The parameter above is for frequencies I don't know if you can change them you can try to play the parameter depending on which hashboard is affected by overheating.
The whole guide on how to apply this parameter is here

Now I remember you who ask for a list of FMS commands.

I think your problem is related to loose heatsink and I think you will need to find that chip to reattached the heatsink.

But if you don't have some tools to reattached those heatsinks follow this guide below to refresh your miner and hashboard and it might also solve your overheating issue on some chips.

Here's my guide https://bitcointalksearch.org/topic/m.58929271

Thank you for pointing out a potential issue with the heatsink; if aging does not work, I might try to reattached the heatsink, but I’ve never done such a repair before.

Thank you for your time

Good day

The temperature of 3-4 chips on the first hash board and one chip on the second board of an Avalon 1166 Pro 81TH are increasing faster (going to 88°C) compared to the temperature of other chips; to counter this problem, we configured the hardware in normal mode instead of high performance. Can someone suggest a fix for this, we would prefer to operate in high performance.

Thank you for your time
