How and why? Its temps are at par with other L3+ stock settings? Can you please be specific for me please. I thought HW were okay so long as effective hashrate was stable.

Thanks in advance.

So info I found from Bitmain...

Temps of the L3+ is different from previous miners, since there are four kinds of temps. What does each of them stand for?
Answer:

Temp(PCB): is the board, “I” is the board intake temp, “O” is the chip outlet temp.

Temp (Chip): is the chips, “I” is the chip temp on the board's intake side, “O” is the chip temp on the board's outlet side.

What’s the range of these temps of the miner?
Answer: We suggest the temp range of miner should keep within 25-80, and usually, it will be 40-70.

I seem to be safely in this range!

-

The temp of the miner only shows two, is it normal?
Answer: Yes, it is normal. In order to check the temp more convenient, the temp of hash board will be cancelled, only the temp of chips will be shown in latter miners. The board will only show the temperature of “O”, and the temperature of “I” will all be 0, which is normal.

Which temp of the miner should I focus on?
Answer: Temp (Chip) is most important, because it is air outlet temp of the miner. It will lead to high temperature protection, if this temp over 80.

Well below 80 so it says I am 'high temp protected"
Furthermore in the 'Miner Configuration' -> 'General Settings' -> 'Miner General Configuration' -> Setup
Stop running when temprerature is over 80℃ - I have this box checked!
Customize the fan speed percentage - I dont have this set but I could experiment and set it to 75-100% to see if I can reduce temps more. Thoughts?

It seems if I can keep the Chips Temp lower than 80 - at 59 now - but lets say below 60 or even 55 then all should be fine right?
The only thing that concerns me is the effect of the HW errors. I know with GPU mining (I know this is an ASIC not a GPU) these are not an issue until they effect hashrate and from what I can tell they are not. Is there way besides the lack of rejected shares I could tell if this effecting my hashrate and or earnings?

I came here seeking any and all advice.
Thank you for your input.
