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

 

Please read this guide carefully before you starting assemble.

Paste heat sink to Raspberry Pi board and attach the extension board to the Micro SD port.

Note: The heat sink is not provided in the packaging. You can buy it here.

Then, fixed the bracket holder to the fan with long steel screws and nuts.

Take one piece of black acrylic layer and put it as base.

Fixed other devices for example: 4 pieces of Raspberry Pi or other combinations. Then combine the 4 layers part with the fan to the acrylic base as following picture, please pay attention to the direction where there is a “R” mark for right side and “L” for left side.

Connect the fan cable to Raspberry Pi on 5V and GND Pin.

Caution: Incorrect polarity may cause damage to your device!

Step 2: Result for the stress test

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

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

4 Layers Cluster Case with Fan– this type of enclosure applies an active cooling mechanism. From the chart, it is obvious that this enclosure is really good at dissipating heat and keeping the raspberry pi temperature at 50 degrees Celsius with a fan ON. This case also provided with attractive colorful LED around the fan while operating.

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 2.1 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 😁.
