5 or 10 minutes ago, I downloaded the last firmware version, and now the model fan it’s just not working (i’ve been printing all day and it was all good)
same problem no model fans after
update
After talking to tec support I did a firmware downgrade which fixed the fans. printers working properly again. Thinking it was something in the last update that caused the fans not to work.
Same, talked to support and did a downgrade of the firmware and that fixed the problem. Curious how the update says “Optimized fan control logic” or something like that and it just makes the fan to stop working xD
Same problem here after update, please share the downgrade tutorial.
thanks in advice
Go to this link Creality Cloud | Page and download the previous version (in this case 1.1.0.50) then put it in to a USB drive. Plug the USB drive in to the printer and in the screen you will get a pop up to install, procede with the installation, and that’s it.
Sorry for my English, I’m from Argentina, but I think I explained it OK.

I have the same issue, turned on machine this morning had the firmware update. after update my fans no longer work. I downgraded to previous firmware version but my fans still don’t work
You should contact Support in this case probably.
I did, they submitted a ticket 
Hola! Pregunta, intento hacer eso con un pen drive, pero no me lo reconoce cuando lo conecto. Sera por algo en particular? Mi maquina hasta hoy funcionaba perfecto, luego envie una impresion y dejo de responder. El teclado tactil ya no responde bien a los click y aparecen errores de camara al intentar hacer un reset de fabrica. Viendo la pantalla la camara como que se conecta y desconecta (dede la pc se ve que funciona).
Pero no puedo hacer el downgrade si no me reconoce el pen drive.
Ahi logre que lo detecte. Pero hay un error que hace que el usb se conecte y se desconecte, entonces no termina la instalacion. Creo que es el error que hace que se vea la camara parpadear en el display
