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:

[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!

That is a amazing, good work my dood!

 

[Sir-Pizza-Bot]

Wow, great work! Can't wait to try this out.

You should probably note that the temps used there are tskin temps (which is "Skin" in the Status Monitor overlay)

what is the benefits of this?

what is the benefits of this?

Higher temperatures-->potentially smaller life of electronics, see ps3 phat rlod, ylod

also when you overclock, this can be handy

So how does this differ from the stock fan ramp up speeds if I may ask?

Did you fully read the first post? If you couldnt understand, then maybe I couldnt properly explain how system works, this is my first tutorial.

I read it for sure. I am just wondering what the difference is from the normal ramp up speeds the switch does versus what changes this does. In numbers if ya had em?

 

[JillianMeadow]

I may understand now, "bumped the speed level by one tier in every section" do you mean you upped the level of the speed per temperature tier in comparison to the base switch?

Yes, exactly. You can see that by comparing default and modified.

Out of interest, how much impact does this have on battery life?

Good question but I really have no idea..

 

[Corpus99x]

I'll keep an eye out
also thanks for the code, my switch feels much more cooler

You're welcome. I'm happy to help.

Very cool (pun intended). I was curious if you have any idea if the option is documented somewhere. I was wondering if the fan curve works in increments, like when you reach the max temp of one interval it switches to the next.

This way you could add hysteresis by adding a slight overlap between intervals.

EDIT: Found some documentation here https://switchbrew.org/wiki/System_Settings#tc

Can I simply erase the "handheld" lines and just leave the console lines of code?

Thank you, I want this because my Switch runs very cool already in handheld, but in dock mode is a bit hot.

Yes, it should work but I suggest first that instead of deleting, copy and replace the default values (look first post). It's safer.

You're welcome. Btw if it runs too hot, maybe your thermal paste is degraded. And Nintendo uses weird thermal paste (has brownish colour) between outer shell and upper thermal block. If you have a chance, I highly suggest that repleace it with realiable thermal paste like Arctic MX-4.

Yes, I just added the lines needed for the console on dock mode only, and it worked great. By the way I used this fan speeds to make the Switch less noisy but still staying cooler:

[tc]
tskin_rate_table_console = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 102], [43000, 53000, 102, 153], [53000, 58000, 153, 255], [58000, 1000000, 255, 255]]"

The problem with your temps was that the fan would kick in at 60% (when reaching 50c) and then it stays there even if the temps decrease.

Hello, I am using latest atmosphere. Is there any reason why my atmosphere fails to boot when I add this piece of code to the system_settings.ini in atmosphere/config/system_settings.ini?

[tc]
; Unlock fan speeds
 tskin_rate_table_console = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 102], [43000, 53000, 102, 153], [53000, 58000, 153, 255], [58000, 1000000, 255, 255]]"
 tskin_rate_table_handheld = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 102, 102], [43000, 48000, 102, 153], [48000, 53000, 153, 153], [53000, 1000000, 255, 255], [48000, 1000000, 255, 255]]"

I added that piece of code at the bottom of my system_settings.ini file and it fails to boot. It only successfully boots when I add the semicolon ";" before the code to each line and it becomes green(using notepad++, of course). Does the setting still take effect this way or is it being commented out with the usage of ';'? Thanks! Below I have attached my config file incase something may be wrong with it. Thank you very much
