Orange Pi Zero 3

[ag123]

this is somewhat 'off-topic' but still relevant to 'orange pi zero 3'

 

If Orange Pi Zero 3 is operated in warm climates (e.g. room temperature 30 deg C etc) , it can at times run up to like 60 deg C.
this is in open still air 

 

adding a fan blowing at it reduce that by some 20 deg C to 40 deg C !

And this is my ghetto fan setup, no fancy case, no heatsink nothing, just a single long machine screw that lifts it up

 

checking temperatures is easy

> armbianmonitor -m
Stop monitoring using [ctrl]-[c]
Time        CPU    load %cpu %sys %usr %nice %io %irq   Tcpu  C.St.

18:03:39   480 MHz  0.00   0%   0%   0%   0%   0%   0%  40.8 °C  0/7^C

strictly speaking, 60 deg C is 'nothing to scream about' , I've a Rpi 4 hitting up 80 deg C and it throttles.
similarly use a fan blowing at it + a heat sink over the cpu, drastically reduce running temperatures.

for 'occasional' use, I don't think it is necessary to have a fan blowing at the Orange Pi Zero 3.

I think it is feasible to run at lower temperatures if I disable and unclock the GPU and HDMI, but for now I'm not sure how to go about doing that.
Initially, I'm thinking maybe the wifi is causing it, but now I don't think so, it is moderately likely the gpu is heating it up a bit.
And still air don't seem to dissipate heat very well.
