Cooler Master Pi Case 40 with Aluminum Core Heatsink, Easy-Access Ports, and Universal Mounting

The Cooler Master Pi Case 40 provides a long-lasting, premium enclosure for Raspberry Pi pro-users. The case encloses the Raspberry Pi board in a sleek aluminum shell, further protected by a high-grade TPU bumper. Once assembled, the system runs cool and totally quiet without the need for an additional fan, even at high clock speeds, thanks to the aluminum shell. All connections are rerouted on the sides, allowing for a better look and accessibility. The Pi Case 40's accessibility and high material quality make it one of the most reliable travel cases for Raspberry Pi users.

Designed For On-The-Go Users

The Pi Case 40’s compact dimensions allow it to be portable, while the aluminum, TPU, and plastic housing keep it safe from impacts, minor liquid splashes, and light dust.

Cool-Looking, Cooler-Running Aluminum Core

The aluminum core of the Pi Case 40 serves as a large, passive heatsink to keep the Raspberry Pi running cool and performing at its best without requiring a loud fan. The Pi Case 40 offers an unmatched amount of surface area for its size, allowing higher GPU and CPU frequencies out of the box.

Reprogrammable Power Button

The case comes with a power button to easily power on and off the system without having to remove the power source from the Raspberry Pi. The power button is reconfigurable to any other action with a simple change in code.

Easy-Access Ports

All ports are quickly accessible thanks to a no-interference design. The GPIO ports are rotated 90 degrees and accessible via the side flap in the TPU bumper. A slit in the TPU bumper allows both display and camera cables to be routed outside the enclosure. Side access to the GPIO only allows the use of jumper cables. Pi Case 40 is not compatible with devices that only require direct connection to part or the entire GPIO of the Raspberry Pi with a traditional layout. Please see the product images for more information on the GPIO pin layout on the Pi Case 40.

Universal Mounting

Four VESA or wall mounting brackets come included to fix your Raspberry Pi to every surface and monitor.

All-In-One Software Utility

The utility allows users access to a basic set of overclocking profiles, tested and validated based on the thermal performance of Cooler Master's Pi Case 40 enclosure, monitoring of system metrics, and the assignment of multiple functions to the built-in button. The Pi Tool can be installed on the Raspberry Pi OS on a Raspberry Pi 4. Installing it is very simple. Just open a terminal, paste the lines into it, and hit return. The installer will then guide you through the installation.


The overclocking feature included in Pi Tool modifies the following values in /boot/config.txt: over_voltage, arm_freq, gpu_freq. Users can further modify the overclocking, by editing the values themselves. (sudo nano /boot/config.txt) Overclocking may cause system instabilities, most show up immediately with a failure to boot. If this occurs, hold down the shift key during the next boot. This will temporarily disable all overclocking, allowing you to boot successfully and then edit your settings.

System Monitoring

Pi Tool offers a section dedicated to monitoring the system's status and performance, which is useful to track thermal output and clock speed when adjusting overclocking settings and to have a quick visual representation of the system's status. Included metrics are core temperature, core frequency, RAM usage, and system load.

Button Remapping

Pi Case 40 includes a button that shortens pins 5 and 6 when pressed (GPIO3 and GND). Out of the box, this allows us to wake up a Raspberry Pi from its halt state. Pi Tool builds upon this function by allowing users to not only assign a function to the button to be triggered when the system is running but also to set up sequences of short and long button presses, allowing additional functions to be triggered by the same button.
