Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the GeeekPi ICE Tower Cooler for Raspberry Pi 4 Model B. This cooling solution is designed to efficiently dissipate heat from your Raspberry Pi, ensuring stable performance, especially under heavy loads or during overclocking. Please read these instructions carefully before proceeding with installation.
Product Overview
The GeeekPi ICE Tower Cooler is an active cooling system featuring a tower-style heatsink with multiple copper heat pipes and a fan. It is specifically designed for the Raspberry Pi 4 Model B to provide superior thermal management. The fan includes RGB lighting for visual indication and can be configured for different speed modes.

- ICE Tower Cooler (Heatsink with pre-attached fan)
- Mounting Brackets (2 pieces)
- Screws and Standoffs (various sizes for mounting)
- Thermal Pads (for CPU and RAM)
- Small Screwdriver
Setup and Installation
Follow these steps to install the ICE Tower Cooler on your Raspberry Pi 4 Model B:
- Prepare the Raspberry Pi: Ensure your Raspberry Pi 4 Model B is powered off and disconnected from all peripherals.
- Apply Thermal Pads: Carefully peel off the protective film from both sides of the thermal pads. Apply the larger thermal pad to the CPU of the Raspberry Pi and the smaller ones to the RAM chips, if desired. Ensure good contact.
- Attach Mounting Brackets: Secure the two metal mounting brackets to the base of the ICE Tower Cooler using the provided small screws.
- Position the Cooler: Align the cooler with the mounting holes on the Raspberry Pi board. The heatsink should sit directly over the CPU with the thermal pad in between.
- Secure the Cooler: Use the longer standoffs and screws to secure the cooler to the Raspberry Pi board. Tighten gently to ensure firm contact without over-tightening.
- Connect the Fan: The fan uses a 2-pin connector. You can connect it to the Raspberry Pi's GPIO pins for different operating modes.

Fan Connection Options:

- Full Speed Cooling Mode: Connect the Red Cable to GPIO Pin 4 (5V power) and the Black Cable to GPIO Pin 6 (Ground). This provides maximum cooling performance.
- Quiet Cooling Mode: Connect the Red Cable to GPIO Pin 2 (3.3V power) and the Black Cable to GPIO Pin 6 (Ground). This reduces fan speed and noise, suitable for lighter loads.
Operating Instructions
Once installed and connected, the fan will begin operating as soon as the Raspberry Pi is powered on. The RGB lighting on the fan will illuminate, indicating operation.

The cooling performance will vary based on the chosen connection mode (5V for full speed, 3.3V for quiet mode) and the ambient temperature. Monitor your Raspberry Pi's CPU temperature using appropriate software tools to ensure optimal performance.
Maintenance
To ensure the longevity and efficiency of your ICE Tower Cooler, perform the following maintenance:
- Dust Removal: Periodically inspect the heatsink fins and fan blades for dust accumulation. Use a soft brush or compressed air to gently remove any dust. Ensure the Raspberry Pi is powered off before cleaning.
- Thermal Pad Inspection: If you notice a significant increase in operating temperatures over time, inspect the thermal pads for degradation. Replace them if necessary.
Troubleshooting
- Fan Not Spinning:
- Check if the fan's 2-pin connector is securely attached to the correct GPIO pins (5V/3.3V and Ground).
- Ensure the Raspberry Pi is powered on.
- Verify that the fan blades are not obstructed.
- High Temperatures Despite Cooler Installation:
- Confirm that the thermal pads are correctly placed and making good contact between the CPU/RAM and the heatsink.
- Ensure the mounting screws are tightened sufficiently to create proper contact pressure.
- Check for dust buildup on the heatsink fins and fan.
- Verify the fan is connected to the 5V GPIO pins for maximum cooling if high temperatures persist.
- RGB Lights Not Working:
- The RGB lighting is integrated with the fan's power. If the fan is spinning, but lights are off, there might be an issue with the fan unit itself.
