High-Performance Cooler

This is a compact high-performance cooler designed for Raspberry Pi 4. It comes with a 30mm PWM fan. The fins of the cooler are made of aluminium. The smaller form factor with just 43mm height makes the cooler compatible with the KKSB Raspberry Pi 4 Tall Case (sold separately).

Intelligent Fan

The 30mm 5V PWM fan included in the box responds to the CPU temperature. It starts automatically when the CPU is too hot and stops when the CPU temperature drops to a certain degree.

You can configure the start and stop temperature limits from Raspberry Pi OS settings. This feature increases the life of the fan since it only runs when needed. With its Sealed Sleeve Bearing (SSB) system, the KKSB PWM Fan has a life expectancy of 30,000 hours.

Examples of Possible Applications

The KKSB 30mm 5V PWM Fan has 3x wires. Please connect each wire carefully to the right GPIO pin as shown below.

Red Wire (5V) corresponds to the GPIO Pin 4
Black Wire (Ground) corresponds to the GPIO Pin 6
Blue Wire (GPIO 14 TXD) corresponds to the GPIO Pin 8

Why Should You Choose This Cooler?

The KKSB Raspberry Pi 4 High-Performance Cooler apparently looks similar to other Raspberry Pi coolers in the market. However, it has the following distinct features that make the KKSB Cooler more effective than most of the coolers available in the market:

Flat aluminium base ensures perfect CPU contact. The heat pipe of the KKSB Cooler is pressed along the block such that the interface along the CPU remains flat.
Quiet operation at all modes, with minimal sound. it only operates when the temperature is above the configured limit so it stays off during the normal workload.
Nickel plated for enhanced performance
Soldering between thermal pipe and heatsink optimizes heat transfer.
Compact size, suitable for use in the KKSB Raspberry Pi 4 Tall Case. The height of the KKSB High-Performance Cooler is just 43mm (4.3cm). This means that you can also use this cooler inside the KKSB Raspberry Pi 4 Tall Case.
