Low-Profile Plus CPU Cooler

Descriptions

The Low-Profile Plus CPU Cooler is an advanced cooling solution designed for high-performance computing within compact spaces. It evolves from the Ice Tower Cooler, offering enhanced thermal performance coupled with a sleek aesthetic. This cooler features a quad-copper-pipe design for superior heat dissipation, complemented by aluminum fins that maximize heat transfer. An integrated fan ensures heat is efficiently expelled, maintaining the processor at optimal operating temperatures.
NOTE: The Fan is controlled by Raspberry Pi OS itself, and it will turn on once the CPU temperature is reached to 50 degree!

NOTE: Raspberry Pi 5 development board does not include in the package, additional purchase required! 

Important Note

As the temperature of the Raspberry Pi 5 increases, the fan reacts in the following way:

• below 50°C, the fan does not spin at all (0% speed)
• at 50°C, the fan turns on at a low speed (30% speed)
• at 60°C, the fan speed increases to a medium speed (50% speed)
• at 67.5°C, the fan speed increases to a high speed (70% speed)
• at 75°C the fan increases to full speed (100% speed)

Temperature decreases use the same mapping with a 5°C hysteresis; fan speed decreases when the temperature drops to 5°C below each of the above thresholds. At boot the fan is turned on, and the tachometer input is checked to see if the fan is spinning. If it is, then the cooling_fan device tree overlay is enabled. This overlay is in bcm2712-rpi-5-b.dtb by default, but with status=disabled.

The radiator's excellent heat dissipation often makes users think the fan is faulty. In reality, the fan doesn't spin because the temperature doesn't reach the activation threshold. During testing with the sysbench command in a loop, the CPU temperature was raised above 50°C to start the fan. But soon after, the temperature drops back below 50°C, and the fan stops again.
