This means that you can also use this cooler inside the KKSB Raspberry Pi 4 Tall Case. The height of the KKSB High-Performance Cooler is just 43mm. The soldering between the heatsink and pipe of this KKSB Cooler optimises heat transfer through better contact. Most Raspberry Pi coolers in the market have no soldering between the thermal pipes and heatsinks. Soldering between Thermal Pipe and Heatsink The KKSB High-Performance Cooler Unit is nickel plated. In addition, it only operates when the temperature is above the configured limit so it stays off during normal workloads. The KKSB PWM Fan on this high-performance cooler produces minimum noise even at maximum mode. The heat pipe of the KKSB Cooler is pressed along the block such that the interface along the CPU remains flat. This is why their contact area remains uneven.

Most Raspberry Pi coolers in the market have pressed heat pipes without CNC-machine treatment. The flat aluminium base makes perfect contact with the CPU. 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 for perfect CPU contact The KKSB Raspberry Pi 4 High-Performance Cooler apparently looks similar to other Raspberry Pi coolers in the market. What makes it different from other Raspberry Pi coolers? The smaller form factor with just 43mm height makes the cooler compatible with the KKSB Raspberry Pi 4 Tall Case. The cooler comes with a 30mm PWM fan and has fins made of aluminium. This is a compact high-performance cooler designed for the Raspberry Pi 4.
