My switch's fan speed runs at 90% speed with just ~53-54c on my SoC(seen from tesla overlay) in handheld with all clks maxed out and thats just too aggressive and ridiculous to me of how nintendo has implemented the fan speed settings to cool itself.

I had been searching for solutions but no avail to overwrite the default fan speed settings for the SoC.
However, i had found and managed to control only the skin temperature using "tskin_rate_table_handheld = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 51], [43000, 48000, 51, 102], [48000, 53000, 102, 153], [53000, 1000000, 153, 153], [48000, 1000000, 153, 153]]"" code retrieved from https://switchbrew.org/wiki/System_Settings

It seems there isn't any existing code available to control neither the SoC nor PCB and trying "tSoC_rate_table_handheld" doesn't change anything.

I don't do any programming/hacking into then switch's system hence i'm unable to retrieve any information that could help me.

Im wondering if anyone has any info bout this or able to dig out anything regarding to the fan speed settings code.

Im currently looking into "tskin_soc_coefficients_console" code but i don't understand what the default value "[6182, 112480]" means..

Any help/knowledge you have would be deeply appreciated and this would benefit to others needing these feature too

Mind you my phone runs ~50c too in games and tegra x1 can handle 104c max with throttling from 70c.
This is still nowhere near from damaging it and i noticed it also usually idles at 20% with just ~40c and that's just waste of my battery.

bump, if someone can make a thing that uses only the pcb's temp that would be nice, since my soc temperature chip is broken and it's driving down the tskin value
