i make this post to ask why my orange pi zero reaches easy 85 degrees with a heatsink applied to it. It is placed in a big case. Maybe the temperature reading is wrong? i check temperature with "

armbianmonitor -m and i get:

Time        CPU    load %cpu %sys %usr %nice %io %irq   CPU
09:28:26:  480MHz  0.55  28%   4%  23%   0%   0%   0%   86°C
09:28:31:  240MHz  0.51  28%   4%  23%   0%   0%   0%   86°C
09:28:36:  480MHz  0.54  28%   4%  23%   0%   0%   0%   86°C
 

what can i do? I'm actually using the orange pi zero as a flight tracker, which is a very cpu and Wi-Fi intensive task, but i think that 86 degrees  are too much!!

 

Any chance to try to touch device with fingers?

well, a heatsink is to just spread heat out more evenly. It does NOT cool the device actively.

If you place a heatsink in a case, that may not be a good solution.

 

I suggest you to put a fan above it and see if it gets better.

That works surprisingly well even with zero airflow around. If you use the search function you'll find numbers.

 

Wrt real topic: https://forum.armbian.com/index.php?/topic/4313-new-opi-zero-yet-another-high-temperature-issue/ (nobody uses search function here and nobody tries to nail the culprit down)

 

Based on personal experience, my device runs under 3 heatsink ( 2 for ram, 1 for cpu ), my country is humid and it hovers about 27 degree celcius.

 

Temperature averages at around 50 deg under 30% constant load through motion software. 

But when it loads, it runs about 75 deg ++ without any fan.

It is always in full load... and i see that reaching theese temps is "normal". I can't cool it actively because the device is placed outside and water can't enter. How can i solve the problem? The case is a lot bigger than the orange pi, but closed. 

i have a new orange pi zero. its v1.4. temperature idle around 70 deg. ugh... 

The same problem..  Temperature on CPU is very much ..  Any advice on the solution? 

 

70.7°C on picture.

I have OPiZero v1.4 with kernel 4.13.5 and temperature and with small heat sink on CPU
