Shop compatible electronic cooling fans, fan HATs and accessory bundles for Raspberry Pi at Communica. Local stock, VAT invoices and branch pickup options available.
Choose 5V fans and the correct 2/3/4-pin connector for easy Pi integration.
Check Samrand and branch availability to avoid project delays.
Consider fan+heatsink combos, HAT controllers and connector kits.
Small single-board computers like the Raspberry Pi can throttle performance when CPU or GPU temperatures rise. A compact electronic cooling fan provides active airflow to maintain sustained performance for projects such as home servers, robotics, media centres, and IoT prototypes. This page helps makers, students, technicians and procurement teams in South Africa choose and buy electronic cooling fans compatible with Raspberry Pi models, with emphasis on local availability, lead times and branch pickup options.
Communica keeps a range of small axial and blower fans, fan modules and compatible accessories at the Samrand head office/warehouse and selected branches. Check branch hours and collection options before ordering to manage project timelines: Branches & Trading Hours.
When selecting a fan, confirm voltage, current draw, connector type, mounting footprint, and noise (dBA). For Raspberry Pi projects, 5V fans are usually most convenient. Below is a compact comparison table to guide choices.
| Specification | Typical Range | What it means for your Pi |
|---|---|---|
| Voltage | 3.3V / 5V / 12V | Choose 5V for direct Pi power via 5V header; 3.3V may be available on some HATs. |
| Connector | 2-pin, 3-pin, 4-pin (PWM) | Match header type or use adapters; PWM enables speed control. |
| Size | 25 mm, 30 mm, 40 mm | Smaller fans fit compact cases; larger fans move more air at lower noise. |
| Current/Power | 0.05 A - 0.25 A (typ) | Ensure Pi power supply can handle additional load; typical 5V 2.5 A PSU is sufficient for single fan setups. |
Most Raspberry Pi models expose a 5V and ground pin on the GPIO header for simple 2-pin fan connections. For temperature-based control, use a 3-pin fan with a transistor or a 4-pin PWM-capable fan and a HAT or controller board. See the Raspberry Pi GPIO pinout and accessory categories at Communica for compatible modules: buying guide for electronic cooling fans and available brands at where to buy electronic cooling solutions online.
Confirm that the fan's supply voltage matches your Pi or controller board. If you estimate fan power for procurement, a 5V fan drawing 0.1 A consumes 0.5 W. For multiple fans or add-on HATs, budget additional current in your power supply (show figures in ZAR when sourcing locally and check stock on the All Products index): electronic cooling solutions in Samrand.
Choose based on use case: lightweight case cooling for media playback often needs only a small quiet 25-30 mm fan, while sustained compute tasks benefit from a 40 mm fan or a fan+heatsink combo. Communica stocks fan modules, JST connector leads, fan grills, rubber mounts and low-noise options to build a complete solution locally.
Example: wiring a 5V 2-pin fan to the Pi's GPIO header (pins 2 for 5V and 6 for GND). For PWM control using a 3- or 4-pin fan, route the control line through a MOSFET or use a fan HAT that exposes PWM to the fan header.
