Raspberry Pi 5 Cooling Guide: Aluminum Alloy Case and Active Cooling Fan
The Raspberry Pi 5 is the fastest and most powerful single-board computer Raspberry Pi has ever released. Packed with a 2.4GHz quad-core ARM Cortex-A76 processor, upgraded VideoCore VII GPU, and PCIe 2.0 interface, it delivers desktop-level performance for AI edge computing, NAS storage servers, 24/7 home automation, retro gaming, and video streaming projects.
But with great power comes great heat output. For normal use, adding cooling is optional, although performance may be improved with the addition of active cooling. However, a heavy continuous load, such as rebuilding the Linux kernel, will force the new Raspberry Pi 5 into thermal throttling. To better cool your Raspberry Pi 5 under heavy continuous load, we’re introducing two new hardware solutions for cooling.
What Is Thermal Throttling? How It Ruins Your Pi 5 Projects?
Thermal throttling is a built-in protection mechanism for the Raspberry Pi 5. When the core temperature hits 80°C, the system automatically reduces CPU frequency to lower heat generation. Once it exceeds 85°C, performance drops drastically, and random freezes or shutdowns may occur.
2 Main Raspberry Pi 5 Cooling Solutions:
1. Aluminum Alloy Passive Cooling Case
Upgraded passive cooling solutions adopt a full-body anodized aluminum alloy case, which acts as a large-area integrated heat sink for the entire Raspberry Pi 5 board. It conducts heat from the core chips to the shell for rapid natural dissipation.
Pros: Completely silent operation, excellent heat dissipation than small heat sinks, durable protection.
We have launched 2 Aluminum Alloy cases for Raspberry Pi 5 cooling, which support Pi 5 Active Cooler, PCIe to M.2 NVMe HAT, PoE+ HAT, WiFi Shield PCIe Peripheral Board and more HATs.
ZC501 case is 6mm higher than ZC502 case, which has better compatibility.
2. PWM Active Cooling Fan
The Raspberry Pi 5 is equipped with a dedicated 4-pin PWM fan header, supporting intelligent temperature speed regulation. Unlike fixed-speed fans, PWM fans adjust rotation speed automatically: low speed and quiet at low temperatures, full speed for strong heat dissipation under high load.
Pros: Intelligent temperature control, balanced noise and cooling performance, plug-and-play, perfect compatibility with Raspberry Pi 5.
We have launched the ZP536 Active Cooler for Raspberry Pi 5 cooling, which supports use with aluminum alloy case for better heat dissipation performance.
Support PWM speed regulation. With 3007 ultra-quiet cooling fan and thermal pads, this active cooler can keep your Raspberry Pi 5 at a comfortable operating temperature even under heavy loads, providing effectively excellent heat dissipation.
How to Monitor Pi 5 Temperature & Cooling Effect
You can easily check your Raspberry Pi 5 core temperature with a simple command to verify your cooling solution’s performance:
vcgencmd measure_temp
Ideal Temperature Range:
① Idle state: 30°C–45°C (excellent cooling effect)
② Medium load: 45°C–60°C (stable performance)
③ Full load: Below 65°C (no thermal throttling at all)
Common Raspberry Pi 5 Cooling Mistakes You Need to Avoid
Many users fail to get ideal cooling effects due to wrong configurations. Check these common mistakes to optimize your Pi 5 cooling system:
① Using Pi 4 cooling accessories: The Pi 5 has a new chip layout and independent fan interface. Pi 4 heat sinks and fans cannot fit perfectly and will affect cooling efficiency.
② Improper heat sink installation: Too much or too little thermal paste, or loose heat sink adhesion will lead to poor heat conduction and overheating.
③ Sealed case without airflow: Fully enclosed plastic cases block air circulation, causing heat accumulation even with fans installed.
④ Blindly pursuing high-speed fans: Fixed high-speed fans produce loud noise without intelligent speed adjustment, ruining user experience.
