Does CPU have temperature sensor?
May be command line or menu command exist for this?
Yes, Zero4K have cpu temperature sensor.
On OpenBlackHole image you can see a temperature, on menu/information/about window.
And which temp is ordinary?
My Zero4K is around 60-62°C, room temperature 25°C.
OpenBlackhole preview, check pics, temp is 67°C.
Temp betwen 60-70 is ok.
I think will be problem if will be bigers from 70
Im gonna open the box try to add small fan 5V with external supply, just to see if cooling will improve.
U can grab 5V from bottom if it will be needed. (I did not check it!) Sorry for offtop.
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.
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.
Friends very importend is place where is your box and change this doing big difrence in temp.
@Matrix10, box is runnig smootly on both temperatures, yes. But what do you think is the best? You dont have to be a so defensive, we all come here to learn something.
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.
maybe not, but 10 degrees less temperature make you sleep better !
Dependent I sleep better at high temperatures
than in winter.
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
TV OLED 2000 euro no fans
Zero 4K 150 euro with fans
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!
