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 ;-)

Standard settings are perfectly fine if you don't overclock.

You find them in the first post, but they are already set.
So you don't need to add them.

May I ask what is the safest temp for the Switch, during hard gameplay?

swutch · Jan 27, 2023

Anything below 58C should be safe.
The switch goes into sleep mode if the temp is to high.

fan settings can be adjust in "\atmosphere\config\system_settings.ini"
My config for an OLED with OC:

Code:

The switch reaches usually about 54-57C instead of 45C and the fan rotates at 50-60% instead of 100% at full GPU OC.

Can I used this settings on my Switch V1 Erista?

I'm on firmware 15.01, what settings should I use?

OnPleasure · Feb 27, 2023

I´m on Atmosphere 1.5.0 pre-release / OFW 15.0.1 and this works for me.

This is my Code:

Code:

[tc]
use_configurations_on_fwdbg = u8!0x1
tskin_rate_table_console_on_fwdbg = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 51], [43000, 48000, 51, 90], [48000, 53000, 90, 102], [53000, 58000, 128, 255], [58000, 1000000, 255, 255]]"
tskin_rate_table_handheld_on_fwdbg = str!"[[-1000000, 40000, 0, 0], [36000, 43000, 51, 51], [43000, 48000, 51, 90], [48000, 53000, 90, 102], [53000, 58000, 128, 255], [58000, 1000000, 255, 255]]"
holdable_tskin = u32!0xE290
touchable_tskin = u32!0xFDE8

Fanspeed:
> 36°C = 20% / silent
> 43°C = 20% / silent
> 48°C = 35% / noticeable
> 53°C = 40% / noticeable
> 58°C = 100% / disturbing

---Settings used on a OC Console.---

When using my system_settings u need to rename it into "system_settings.ini".

hi guys, i used the file on the first page and finally i have the fan that goes even at 85% use

I'm reading the instructions inserted in the .txt file, in the second line, about the portable mode, is it normal that the last square bracket is [48000, 1000000, 255, 255] ??
48000 is written in the previous brackets, maybe 58000 should be put?

i.e. like this?
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], [58000, 1000000, 255, 255]]"

I'm asking because i see that the indication of the first temperature in the various brackets is progressive

You must have old FW since on first page those settings don't work on FW 12.0.0+

And it means that it won't drop this fan speed until you will drop temperature below 48C. 53000 is gatekeeping access to 48000,100000.

So until you raise temperature above 53C, you won't get full fan, but when you do, it won't drop until temperature will drop below 48

ah great, now i understand those settings, thanks a lot for the explanation!

....actually i have the 1.5.0 release of atmosphere and the latest nintendo software update installed via daybreak (16.0.0)

and my fan situation changed from day to night, at least in dock

I have not tried in portable mode

p.s.
now that i think about it, maybe latest firmware could cause some bugs

When i played bayonetta 3 on dock, at 60 degrees the fan was used for 85% and not 100% (status monitor infos)

What does "fwdbg" means?
Also what is that for?

Code:

holdable_tskin = u32!0xE290
touchable_tskin = u32!0xFDE8

Config from first page works fine on 16.0.1 btw.

FirmWare DeBuG

You are putting fan into debug state to override its speed curve

Ce tutoriel est obsolète.
Depuis 12.0.0, tskin_rate_table_console n'est plus utilisé.
tskin_rate_table_handheld ne vous donne pas non plus un accès complet au ventilateur, le système peut le prendre en charge et pousser ses paramètres.
Pour régler correctement le ventilateur, vous devez l'activer

use_configurations_on_fwdbg

Ensuite, utilisez-les pour définir des profils de ventilateur

tskin_rate_table_handheld_on_fwdbg
tskin_rate_table_console_on_fwdbg

Cela ne fonctionne que pour 12.0.0+

and nowadays now in 16.0.3 how can we do to slightly increase the speed I speak especially for the last zelda

Soler37 · May 27, 2023

Is there any downside to making the fan run faster at lower temps so that it keeps the switch cooler? (besides the noise)
