bonjour
(si ça peut aider )
j'ai le même problème. j'ai validé que c'était bien logiciel car il fonctionne avec l'image officielle de l'expérimental pi.
je ne suis pas un expert mais lorsque je compare les 2 images, il manque un fichier ose.cfg dans recalbox, qui je pense gère entre autres le ventilo.
Pour rigoler j'ai faits un copier-coller mais ça n'a rien changé.
le voici :
#icon size, defaults to small if medium or large are not set
small
#medium
#large
#loadwait sets an application to wait to open before closing the boot splash screen
#loadwait
#emulationstation
#red LED maximum brightness
redled
30
#green LED maximum brightness
greenled
10
#volumeicon enables displaying the volume slider when changing volume
volumeicon
#fanduty defines the number of temperature bands and fan power for each given temperature.
#fanduty defaults to full speed if underfined.
#temps are in millidegrees
#duty/power is in tenths of a percent. 0 to 254 = 0% to 25.4% duty. Setting 255 will set 100% power.
#on boot fan is set to 100% power until changed by osd or third party applications.
