Common thermal products and when to use them
Choose your thermal components based on power dissipation, form factor and airflow constraints.
| Product | Typical use | Good for |
|---|---|---|
| Passive heatsinks | Low-power ICs, regulators | Silent operation, compact boards |
| Axial and blower fans | Active cooling for enclosures and power supplies | Higher heat flux with airflow |
| Thermal pads & paste | Improve conduction between components and heatsinks | Uneven surfaces, GPUs, MOSFETs |
Pro tip: For prototypes, buy a selection of thermal pads (0.5-2.0 mm) and a small tube of thermal paste to test both mechanical fit and thermal performance before committing to a final solution.

Specification callouts to check
- Thermal resistance (°C/W) for heatsinks when available
- Fan dimensions, airflow (CFM) and nominal voltage (12 V or 5 V)
- Thermal conductivity (W/m·K) and thickness for pads

Selecting the right thermal solution - practical guidance
Start by estimating the heat to be dissipated and the available mounting area. For small boards, calculate steady-state temperature rise using simple power-to-thermal calculations and choose components with adequate margin.
Quick calculation examples
Ohm’s law and power basics help estimate heat from resistive loads. For electronics, use:
Power (P) = Voltage (V) × Current (I). Example: a regulator dropping 5 V at 0.5 A dissipates P = 2.5 W. If your heatsink thermal resistance is 10 °C/W, the temperature rise is 25 °C above ambient.
P = V × I DeltaT = P × Rtheta (°C/W)
Use these numbers to decide if passive cooling is sufficient or if you need a fan-assisted solution.
Compatibility and accessories
Consider mounting hardware, thermal adhesives, and airflow direction when ordering. Communica stocks mounting clips, fan cables and controller modules-check compatible brands and accessories on the Shop by Brand page to match parts correctly.
For students and labs, Communica’s Samrand branch supports account invoicing and supply for coursework; see branch hours and collection details on the Branches & Trading Hours page.
Availability, lead times and local support
Local availability can vary by product. Popular maker brands and commodity heatsinks and fans are often in stock at Samrand, while specialised thermal interface materials or large extruded heatsinks may have lead times. Use the Check Stock in Samrand feature on the homepage to confirm current availability and reserve items before travel.
Example procurement workflow for a Cape Town university lab: 1) Check stock online, 2) Request a quote for volume pricing, 3) Reserve for Samrand pickup or arrange delivery with invoicing in ZAR. Estimates for collection times are published on the Branches & Trading Hours page.
Compare, buy and collect
Compare specs across brands and product families using the site catalogue. If you need to buy now, use Shop Now to add items to your cart, Check Stock in Samrand to confirm availability, Compare Specs to evaluate options, or Request a Quote for larger orders or education discounts.
