    Yes, Zero4K have cpu temperature sensor.
    On OpenBlackHole image you can see a temperature, on menu/information/about window.

    Yes, i know about this picture, but i never experiment with box power source, i use d-link usb hub with his own power supply.
    Zero4K have only one usb port, i use dvb-t stick, usb stick 32gb for recording and wifi donge on dlink usb hub. Usb hub with its own power is almost mandatory with this box.
    Will check temperatures, i will come back with photos and info.

    Ok, finally i found time to test Zero4K cooling. I use 12V pc fan on 7.5V with external supply to lower the rpm and noise. I did not open the box, just i put the fan on top of the Vu+ box. Temperature drop from 61 to 50°C in 2-3 minutes time. I decided to leave the fan and improve Zero4k cooling.

    Hm, looks like plastic box is trash. CPU is suffocated in it.

    Very interesting.

    Temperature drop from 61 to 40-42°C after 30 min. Now is around 40°C, with fan, at room temperature 22°C.

    What is the temperature of the processor in your computer?
    50-70 C ???
    The Zero 4K runs smoothly without a fan.

    That's hard to say.
    I do not intend to humiliate an idea if it is based on a technical calculation.
    It is expected that the manufacturer uses the guaranteeing components
    stable operation at working temperature.
    The processor itself has its own specifications and requirements for active or passive cooling.
    The device manufacturer then calculates passive or active cooling.
    The receiver is based on passive cooling
    and they certainly counted on a certain processor temperature and other components.
    Otherwise, thousands of receivers will be in service after three months of use
    in summer conditions.

    Let's say for example
    some of the components in the TVs are getting hotter than in the receiver
    and there is no fan.
    Of course, if the receiver is indoors
    without good air circulation or in a room where the summer temperature is high
    then extra cooling can prolong the service life.
    However, in other cases (room temperature abt 21 C and free circulation of air) it is questionable whether it has any significant influence.

    Dependent I sleep better at high temperatures
    than in winter. :chair:

    Not to say, that I do not like any sounds from the receiver.
    It is the enjoyment with receivers and computers with no noise.

    So why not put fans on the TV :D
    TV OLED 2000 euro no fans :D

    Zero 4K 150 euro with fans :welcome:

    Of course it depends on you fans or no fans
    whether or not to use it, but I tried to clarify the technical side.

    remaining on the technical side,
    I would place on a Scythe Slim Stream Slip + 1 RunCam ll so I could use the box also as DRONE
    taking advantage of the upward current formed by a mass of air that rises in altitude!
