Low Profile ICE Tower Cooling Fan Stressberry Test


This guide is provided for information and as it is. Cytron Technologies will not be responsible for any damage or data lost during the installation process. Do backup your microSD card if you have any concern.





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


All the components that provided in the packaging are shown below.

Step 2: Result for the stress test

I have overclocked and ran the stress test on the Low Profile ICE Tower Cooling Fan to observe how great the fan dissipates heat from the Raspberry Pi 4. The chart below shows the stressberry graph for the Low Profile ICE Tower Cooling Fan.


From the chart, we can see that the Raspberry Pi can dissipate heat better with the fan. 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.

Low Profile ICE Tower Cooling Fan– this type of fan 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. Not only that, this ICE Tower Fan also comes with attractive colorful lighting around the fan. Bear in mind that this ICE Tower is tall and not suitable to use with other enclosures.

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?
