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:
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.
The installation for this fan is super easy and the packaging also comes with the manual.
Paste a thermal pad on the CPU of the Raspberry Pi. This one is provided in the packaging.
Note: Silicon Thermal Pad is a must for proper thermal conductivity. Please make sure you place it properly.
Make sure that the header of the Argon Mini FAN HAT is aligned with physical PINS 1-12 of the Raspberry Pi.
Check if the heat sink of the Mini fan is in contact with the thermal pad.
Set mode of the Argon Mini Fan:
Setting the PWM settings:
Note: This setting will start the Mini Fan at a CPU temperature of 55 degrees Celcius (temp=55000). You may set your own desired initiation temperature as you wish.
The Raspberry Pi is now can be power ON.
I have overclocked and ran the stress test on the Argon Mini Cooling Fan to observe how great the fan dissipates heat from the Raspberry Pi 4. The chart below shows the stressberry graph for the Argon Mini Cooling Fan.
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 Mini Cooling Fan– this type of fan applies an active 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 the mini fan. The design is simple and it is suitable for minimalist type of person.
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 fan.
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 ?.
