Buying electronics cooling systems online in South Africa means balancing specification, availability and installation. Communica offers a wide range of axial and blower fans, heatsinks, thermal interface materials, fan controllers and small liquid-cooling modules suitable for hobby, education and light industrial use. Local stock reduces lead times, enables branch pickup in Samrand, Pretoria or Cape Town, and ensures VAT invoices for institution or company procurement.
When ordering, compare these specifications to ensure compatibility with your project or product:
| Spec | Why it matters | Typical values |
|---|---|---|
| Voltage / Current | Match supply rail (5 V, 12 V, 24 V) | 5 V, 12 V common; check mA/A draw |
| Airflow (CFM or L/s) | Determines cooling capacity for enclosure or heatsink | 10-100+ CFM depending on size |
| Noise (dBA) | Important for lab/office and educational settings | 15-40 dBA typical |
| Size / Mounting | Ensure cut-out fits and screw hole pattern matches | 40 mm, 60 mm, 80 mm, 120 mm common |
Tip: For Raspberry Pi or small SBC cooling, a 40-50 mm fan or small active heatsink is usually sufficient. For power supplies and motor drivers, prioritise airflow (CFM) and ensure the fan voltage matches your supply.
Check connector types (2-pin, 3-pin tach, 4-pin PWM) for direct motherboard or controller connection. Communica stocks commonly used brands and accessories - search fan mounts, vibration-damping screws, and thermal pads in the collections to build complete kits. See product ranges and categories for fast browsing: Shop by Category.
Many cooling items are kept in Communica's Samrand warehouse and branches in Pretoria and Cape Town. For urgent projects or education labs, use the "Check Stock in Samrand" option to confirm immediate availability before ordering. Branch collection policies and hours are available at the branches page: Branches & Trading Hours.
Example: A 120 mm 12 V fan drawing 0.2 A consumes 2.4 W. If your project uses three such fans, plan for ~7.2 W total fan power and select a PSU with spare capacity. Prices and lead times vary; request a quote for bulk orders to get VAT invoices for institutional purchasing.
When placing an order, consider creating an accessory bundle: fans + screws + thermal paste + a basic fan controller. Communica lists compatible accessories on product pages and the shop-by-brand area for easier matching: Shop by Brand. For broad browsing, the full product index is useful: All Products.
