First of all, why subject your Raspberry Pi to this level of stress? In the case of Raspberry Pi 4, the A72 CPU is so powerful that it can overheat if it doesn’t have enough cooling. This results with the CPU being governed (slowed down) to reduce the electrical energy being consumed, and in turn, reducing heat generation. The RPi 3B+ and predecessors could also overheat, however, it was less of a problem for the majority of use cases. A quick stress test, in this case, will reveal if your Raspberry Pi 4 can run at full CPU-load in its case/environment without overheating and not slowing down.

The goal of this tutorial is to create a chart which depicts:

  • A stabilization period at the beginning
  • A period of time for full-load CPU
  • View the CPU temperature
  • View the CPU speed (to witness if the CPU is being governed, or not)

There are a million ways to cool down your Raspberry Pi: Small heat sinks, specific cases, and some extreme DIY solutions. Stressberry is a package for testing the core temperature under different loads, and it produces nice plots which can easily be compared.

The run lets the CPU idle for a bit, then stresses it with maximum load for 30 minutes, and lets it cool down afterwards. The entire process takes around 45 minutes. The resulting data is displayed to a screen or, if specified, written to a PNG file.

 

 

Step 1: Enclosure installation steps

 

The installation is super easy. Open the case and paste two thermal pads at the designated place on the case.

Align middle NEO Case with the Raspberry Pi board. Make sure the Silicon thermal pad is in contact with the CPU of Raspberry Pi.

Fix the bottom case and secure four screws at the plastic base of the NEO Case.

Slide and secure magnetic top of the NEO Case. In case if you want to use GPIO pin or camera, you can put aside this magnetic top.

The Raspberry Pi is now can be power ON.

Step 2: Result for the stress test

I have overclocked and ran the stress test on the Argon Neo Case to observe how great the enclosure dissipates heat from the Raspberry Pi 4. The chart below shows the stressberry graph for the Argon Neo Case.

From the chart, we can see that the Raspberry Pi can dissipate heat better with the case. From my observations:

Bare board – the CPU is doing its best to deal with the generated heat. An interesting compromise that appears to be keeping the CPU well below 80 degrees Celsius.

Argon Neo Aluminum Case– this type of enclosure applies a passive cooling mechanism and of course it is better than bare board in dissipating the heat. The heat from the CPU is absorbed and dissipated through a wide surface area. This case is very compact, and you can assemble it within seconds! Also, you easily have access to the ports with the carefully cut out openings on the case.

Overclock test – the Raspberry pi is overclocked to observe how far the clock frequency can be increased while maintaining the CPU temperature below 80 degree Celsius. The Raspberry Pi can be overclocked to maximum 1.7 GHz with this case.

 

Now you can see that enclosure for Raspberry Pi 4 is really important in dissipating the CPU heat. Interested in having this type of enclosure for your Raspberry Pi?

Let’s get the enclosure at our Cytron product webpage 😁.
