about temp sensor model

[moritezza]

hello,

i have some t17e, i have question about temp sensor model

below is model of a t17e set model:

Code:

2021-05-30 11:02:58:temperature.c:272:calibrate_temp_sensor_one_chain: chain 1 temp sensor NCT218
2021-05-30 11:02:59:temperature.c:272:calibrate_temp_sensor_one_chain: chain 2 temp sensor TMP451
2021-05-30 11:03:00:temperature.c:272:calibrate_temp_sensor_one_chain: chain 3 temp sensor NCT218

as you see two is NCT218 and one is TMP451 , should be similar ?
there is any different if all be NCT218 or all be TMP451 ?

Thanks for your help.

I think your Chain 2 came from a different miner because I have not seen a different sensor on the same miner, both sensors do the same thing but they differ a bit in specs such as the voltage range, I would advise against using different ones.

Also keep in mind that the majority of the time, a temp-sensor error in the kernel log isn't really the result of a bad sensor but rather an issue with one of the chips, it's safe to assume that at least 8 out of 10 times a temp sensor-error is the result of a bad chip, so make sure you check the chips before replacing the sensor.
