KKSB High-Performance Cooler for Raspberry Pi 4

Compact Design - Just 43mm Height
30mm PWM Fan Included
Soldered Heatsink and Thermal Pipes
Nickel Plating
CNC-Machined Flat Base for Optimal Contact
Aluminium Fins

The KKSB cooler with 30 mm 5 V DC PWM fan is very powerful, quiet and lowers the CPU's temperature. This aluminium cooler with fan is specially designed for Raspberry Pi. Thanks to its compact design with a height of just 43 mm, this cooler is compatible with our KKSB Raspberry Pi 4 Tall Case (sold separately).

Features That Make KKSB Cooler Stand Out


Soldering between Heat Pipes and Heatsink Most Raspberry Pi coolers in the market have no soldering between the thermal pipes and heatsinks. The soldering between the heatsink and pipe of this KKSB Cooler optimises heat transfer through better contact.	CNC-Machined Aluminium Base for Perfect Contact The flat aluminium base makes perfect contact with the CPU. Most Raspberry Pi coolers in the market have pressed heat pipes without CNC-machine treatment. This is why their contact area remains uneven. The heat pipe of the KKSB Cooler is pressed along the block such that the interface along the CPU remains flat.	Quiet and Efficient Cooling Fan The KKSB PWM Fan on this high-performance cooler produces minimum sound even at maximum mode. In addition, it only operates when the temperature is above the configured limit so it stays off during the normal workload.	Compact Size 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 (Sold Separately). The height of the cooler is lower than other Raspberry Pi cooling towers in the market.

How to Assemble KKSB Cooler on Raspberry Pi 4

Use Clips with the cooling tower to attach the KKSB PWM Fan
Align the brackets of the tower with the Raspberry Pi 4 screw holes such that the PWM fan is facing opposite the Raspberry Pi 4 GPIO
Secure the tower using screws

Connecting KKSB 30mm PWM Fan to the Raspberry Pi 4 GPIO

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

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

KKSB Sweden specialises in metal cases and their inner cooling. Buy premium fans and metal cases for Raspberry Pi, Odroid, Arduino, Lattepanda and many other SBCs directly from the manufacturer!. The KKSB cooler with fan provides efficient cooling, which prevents the Raspberry Pi's CPU from automatically throttling back under high load. Efficient CPU cooling keeps your Raspberry Pi running at maximum speed for longer. This KKSB cooler with PWM fan keeps your Raspberry Pi cool under load and 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. The KKSB cooler with fan is an important additional to your Raspberry Pi, as it ensures that its components will not overheat. The fins of the cooler are made of aluminium. The cooler's height of 43 mm makes it compatible with our KKSB Raspberry Pi 4 Tall Case (sold separately). The fan has a 7-blade impeller. Dimensions: 30 mm x 30 mm x 7 mm, speed: 5000 ± 900 RPM. The KKSB high-performance cooler with PWM fan has a few features setting it apart from other coolers. At 43 mm high, it is the shortest standing cooler on the market. The aluminium base with the thermal pad is completely flat, providing perfect contact. The KKSB PWM fan produces minimum sound even at maximum mode. The heatpipes are soldered to the heatsink. This optimises heat transfer through better contact.
