Adjust the Nintendo Switch Fan Speed

Erista, what I want is to lower the revolutions of the fan, when it goes from 53 degrees the fan goes from being around 40% to 80% or more and the noise it makes to be at 53 degrees is crazy, but it doesn't work what have i put

The original code was the one from the first post, that is tests that I have been doing to lower the revolutions

If you do that the temp will be higher, and thats not good, this is my values:

[tc]
use_configurations_on_fwdbg = u8!0x1
tskin_rate_table_console_on_fwdbg = str!"[[-1000000, 40000, 0, 0], [36000, 46000, 51, 51], [46000, 52000, 51, 102], [52000, 58000, 102, 255], [58000, 1000000, 255, 255]]"
tskin_rate_table_handheld_on_fwdbg = str!"[[-1000000, 40000, 0, 0], [36000, 46000, 51, 51], [46000, 52000, 51, 102], [52000, 58000, 102, 255], [58000, 1000000, 255, 255]]"
holdable_tskin = u32!0xE290
touchable_tskin = u32!0xFDE8

I know this is not what you want, but you tell me to share it, I have erista too

I never has been able to ear the fan on my console even when using intensive graphics game, I really don't understand this homebrew

If you have low vol at TV and using OC, you hear it, but I don't think it bothers

its crazy to me that people actually want to make their device hotter just because "noise"

hotter? do you think 53 degrees hot? If it seems normal to you that the fan is at 80% or more at 53 degrees, fine for you, but I don't want a turbine when the console is at 53 degrees, it's worse than a ps4, and that at 50cm from the face.

PS: I'm talking about portable mode

I'll try that to see, the problem is that the thermal limit of the portable mode is exaggeratedly low and immediately the fan goes crazy

If I remember well, stock fan at portable don't go more that 60% (153/255), while docked go to 100% (255/255), I unlock full fan at portable because I use OC at some games

uper · Oct 24, 2022

No way, in portable mode it gets more than 80%, I have to lower the OC so that it doesn't go above 53 degrees or it seems that it has a turbine, it only does it in portable mode.

PS: I just tried your code and it works! I can finally play with oc without going crazy with the noise, although I am going to try to make it a little more aggressive because now it is at 55 degrees around 30% and could be around 45% without the noise bothering me. Thank you very much

"my fan too loud how do I lower its speed and potentially cause harm to my device" nope totally don't. the fan is working as its intended to work but you are too worried about the noise.

I copied yours but it's not working, I'm getting black screen after a few minutes of game, so I wanted to try adding 255, 255 to all handheld values to see if with really high fan speed I'd still get black screen, but it's 20-30% with status monitor overlay.
I copied everything you posted, just changed values to 255:
tskin_rate_table_handheld_on_fwdbg = str!"[[-1000000, 40000, 255, 255], [36000, 46000, 255, 255], [46000, 52000, 255, 255], [52000, 58000, 255, 255], [58000, 1000000, 255, 255]]"

Black screen? Something is bad, because it should work, can I see your config file?

Fan stays at 20% and then 30% when playing, I'd like to crank it up to 60% at all times just for testing, I'm almost sure it's temperature related that it's causing the black screen.

Name of the file? Path of the file? Are you using OC? If yes, wich values? Erista or mariko?

Erista, name is system_settings.ini and if I recall correctly it's in atmosphere/config_templates. No OC, fresh install of atmopshere to try to fix the issue, have barely any apps installed as well just tesla for the temperature and fan overlay.

if I want to run fans at maximum speed even on home menu to test, it's just this line:
tskin_rate_table_handheld_on_fwdbg with 255, 255 everywhere, right?

Maybe this works... But I'm not sure

tskin_rate_table_handheld_on_fwdbg = str!"[[-1000000, 1000000, 255, 255]]"

Could you share your ini with us mate?

It's exactly how you described. 45% would be ideal.

I'm just new in Atmosphere CFW all the stuff, I wanna ask what is the most optimize fan speed for my erista switch, with EMUNAND running and no OC, what fan settings ini file should I use? Thank you in advanced ;-)

Works on atmosphere but didn't tested on ReiNX and SX OS.

I'm giving the needed file, copy this to atmosphere>config folder in sd card. DON'T FORGET TO CHANGE THE EXTENSION OF FILE TO .ini OR IT WILL NOT WORK I already modified and bumped the speed level by one tier in every section (except first temps., no need to wear fan on room temp.) for less temperature. Modify if you need.

Default settings are these:

Code:

[tc] tskin_rate_table_console = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 51], [43000, 53000, 51, 153], [53000, 58000, 153, 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]]"

str!"[[-1000000, 40000, 255, 255]
-1000000, 40000 these are temperature 40000 = 40C
255 is the speed, 0-255

Edit: lesser fan speed maybe would NOT work, for built in security. Even if they work, BE CAREFUL YOU CAN OVERHEAT AND DAMAGE YOUR CONSOLE!

This tutorial is outdated.
Since 12.0.0 tskin_rate_table_console is not in use anymore.
tskin_rate_table_handheld is also not giving you full access to fan, system can takeover it and push their settings.
To properly set fan you must enable this

use_configurations_on_fwdbg

Then use those to set fan profiles

tskin_rate_table_handheld_on_fwdbg
tskin_rate_table_console_on_fwdbg

This works only for 12.0.0+
