Heatsink Fan Kit for Raspberry Pi - PWM Fan Cooling Kit

In this review of the Heatsink Fan Kit for Raspberry Pi, the bottom line is clear: this kit is for makers and single-board computer users who need reliable, adjustable cooling across several boards. It stands out because it bundles different radiator materials and fan wiring options so you can match cooling to the job. The kit is especially useful when running thermally demanding tasks on Raspberry Pi 4, Jetson Nano, RockPi or when using a Pi Zero in a compact enclosure; the inclusion of a fan version that supports PWM speed control is the single biggest reason to consider it.

Key Features

• Wide compatibility: Works with Raspberry Pi B, B+, A+, 2, 3, 4 model B and B+ and Pi Zero/Zero W, plus Jetson Nano and RockPi series, so one kit serves multiple SBCs.
• Multiple radiator materials: Includes copper and aluminum radiators so users can choose higher thermal conductivity or lighter weight depending on the project.
• Fan wiring options: Both two-wire and three-wire fans are provided so you can use a simple voltage-driven fan or a PWM-controlled fan for finer speed management.
• PWM speed control: The three-wired fan accepts a PWM signal on the third wire for controlled cooling when noise or power draw matters.
• Low-voltage operation: Two-wired fans run on 3.3V to 5V inputs making them safe for direct connection to typical single-board computer power pins.

Who It's For

The kit is ideal for hobbyists, tinkerers, and small-scale developers who switch between Raspberry Pi models or run Jetson Nano and RockPi boards and want a single cooling solution. It is also useful for anyone building compact projects where different radiator materials or a PWM fan could improve thermal performance.

It is less appropriate for users who need a sealed industrial cooler certified for continuous heavy-duty server use or those requiring active cooling with integrated temperature monitoring and dedicated controllers; in those cases a purpose-built industrial solution should be considered.

Pros & Cons

Pros

• Variety of heat sinks and fan specs gives flexibility for different thermal requirements.
• Three-wire fan supports PWM speed regulation for quieter, more efficient cooling under light loads.
• Compatibility covers a broad range of single-board computers, reducing the need to buy separate kits.

Cons

• Two-wired fans only accept 3.3V to 5V, so they lack speed control unless paired with a PWM-capable fan or additional circuitry.
• Assembly and choosing between copper or aluminum radiators requires the user to judge tradeoffs; less comfortable users may prefer a single plug-and-play cooler.

Our Verdict

This Heatsink Fan Kit is a practical, cost-effective choice for makers and small projects that involve multiple single-board computers. The mix of radiator materials and a PWM-capable fan give useful flexibility, making it good value for those who tinker with different boards and cooling needs; professionals seeking an out-of-the-box industrial cooler should look elsewhere.

Frequently Asked Questions

Do two-wired fans support speed control?
Answer. Two-wired fans accept 3.3V to 5V input and do not support PWM speed control without extra hardware.

Can the three-wire fan be controlled by the Pi?
Answer. Yes, the three-wired fan has a blue wire that accepts a PWM signal for speed regulation when connected to a PWM-capable header.

Are the heatsinks suitable for heavy continuous loads?
Answer. The kit improves cooling for many SBC tasks, but for continuous heavy server-level loads an industrial-grade cooler is recommended.
