Hello guys, in this tutorial, I am going to compare heating (Thermal Testing) results of raspberry pi with dual fan heat sink aluminium armor and without heat sink & fan. So lets get started.
I did two experiment, one without heat sink and fan. Second with dual fan heat sink aluminium armor.
I did both the experimentation then i realized that i could use “watch” command for monitoring the temperature. But i am showing how you can use watch command.
Just type watch before the command. That said. It will run that command every two second and display output in console like this. Every two second it will update current temperature of GPU.
watch vcgencmd measure_temp
Raspberry Pi Temperature Command:
1) Raspberry Pi GPU temperature
2) Raspberry Pi ARM CPU temperature
cpu=$(</sys/class/thermal/thermal_zone0/temp) echo "$((cpu/1000)) c"
divide output by 1000 to get ARM CPU temperature.
Experiment 1: Without Heatsink and Fan.
I am going to run it for one hour. In first half an hour i will be playing youtube videos to see how much it will increase the temperature. Next half will be idle. We will see how it drop the temperature.
Now We can see maximum temperature was 82 *C and minimum temperature was 65 *C. My ambient was temperature 30 *C.
Experiment 2: With Dual Fan and Heatsink.
Similarly we will run youtube video on raspberry pi for half an hour and watch how much temperature is increased. Next half an hour will be idle. We can see clearly difference between the temperatures with dual fan and heat sink and without heat sink & fan. We can see maximum temperature was 61 *C and minimum temperature was 45 *C.
If we consider my room temperature which is 30 *C. This dual fan heatsink armor dissipate heat nicely.

Till then keep learning keep making.
