Guide on how to adjust the Switch FAN SPEED

Add code [tc] in atmosphere\config\system_settings.ini

[tc]
use_configurations_on_fwdbg = u8!0x1
tskin_rate_table_console_on_fwdbg = str!"[[-1000000, 10000, 64, 64], [35000, 41000, 80, 100], [41000, 45000, 100, 128], [45000, 51000, 128, 255], [51000, 1000000, 255, 255]]"
tskin_rate_table_handheld_on_fwdbg = str!"[[-1000000, 10000, 40, 40], [35000, 41000, 64, 90], [41000, 45000, 90, 128], [45000, 51000, 128, 255], [51000, 1000000, 255, 255]]"
holdable_tskin = u32!0xEA60
touchable_tskin = u32!0xEA60


Change the XX000 values for Temperature. Example=(51000 = 51C)
Change the YYY values for FAN Speed. Example=(255 = 100% FAN)
[XX000, XX000, YYY, YYY]
[45000, 51000, 128, 255]
[45C, 51C, 50%FAN, 100%FAN]

Speed FAN
16=6.25% FAN
32=12.5% FAN
64=25% FAN
96=37.5% FAN
128=50% FAN
160=62.5% FAN
224=87.5% FAN
255=100% FAN
(+- 2.55=1%+Speed FAN)

tskin_rate_table_console_on_fwdbg = Dock Mode
tskin_rate_table_handheld_on_fwdbg = Handheld Mode

holdable_tskin = u32!0xEA60
touchable_tskin = u32!0xEA60
use_configurations_on_fwdbg = u8!0x1

what this are doing iam pretty sure iam using config without it and its working fine??

use_configurations_on_fwdbg = u8!0x1

Without this your custom fan speeds won't work for 12.0.0+ FW
You will just have default config still applied

tskin_rate_table_console = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 76], [43000, 48000, 76, 153], [48000, 53000, 153, 204], [53000, 58000, 204, 255], [58000, 1000000, 255, 255]]"
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]]"
