Fan optimised for 2S ?

[Vincèn 0]

Hi,

 

I'm using some 2S for a touchpanel project that is mounted in a wall, so basically in a closed box. I have installed the big heatsink included with the 2S but I find it very hot all time ! I'm concerned in a nearly closed environemnt it might overheat quite quickly ! Some fans to advise that I could install easily and safely on it and plug on the dedicated fan connector on the board ?

 

Thanks

No one on this ? and no admin to validate post ??? Dead forum by Asus ??

hello @Vincèn, 

this is the hardware specification of tinker board 2s, the board should work fine if the temperature falls in the tolerated range. i'm not quite sure what you need, are you installing a fan apart from the heatsink?

Environment

Operation temperature: 0℃ ~ 60℃ Non operation temperature: -40℃ ~ 85℃ Non operation humidity: 0% ~ 85% (Non condensing)

Hi Vincen,

If you worried about overheat issue on it, suggest to use fan on FAN connector as below. Here is reference for FAN part number (SUNON, MF30060V1-10000-A99)

I have a question referring to this, from the wiki on github

• For Tinker Board 2 / Tinker Board 2S

• The FAN connector offers 500mA maximum by hardware design.

• It provides be controlled High/Low speed by software and kindly find the control method below:

  1. High speed setting on FAN_SPD_CTRL

     sudo -i
     echo "154" > /sys/class/gpio/export
     echo "out" > /sys/class/gpio/gpio154/direction
     echo "1" > /sys/class/gpio/gpio154/value
     

  2. Low speed setting on FAN_SPD_CTRL

     echo "0" > /sys/class/gpio/gpio154/value

     _____________________________________________________

     This works flawless, I can set 2 speeds. „Fast“ and I’d call it „medium“.

     i would appreciate a „slow“ and „silent“ setting! The two that are already available are to fast and loud. How can I get this feature? Can someone Programm it?

     (I tried to plug my fan in the 3volt and it runs super silent  but I am afraid to damage something related to the max 50ma output . The fan is at 48ma at 5V in the documentation)

     Cheers
