Why Thermal Paste Matters in Electronic Cooling
When mounting a heat sink to a CPU, power transistor, voltage regulator, or industrial module, a thin layer of thermal paste (also called thermal compound or grease) is essential. It fills microscopic gaps between surfaces, reducing thermal resistance and ensuring effective heat transfer. This helps your devices run cooler and more reliably, especially under demanding loads or in South Africa's warmer climates.
Available Types and Brands at Communica
At Communica, you'll find a selection of thermal pastes and compounds both in high-performance formulas for CPUs/GPUs and more general electronics grades for industrial heat sinks. Choose from top makers such as MG Chemicals, Arctic Silver, and proven OEM suppliers compatible with a broad range of applications.
| Type | Typical Use | Thermal Conductivity | Brands at Communica |
|---|---|---|---|
| Silicone-Based | General electronics, power modules | 0.8-1.2 W/mK | MG Chemicals, RS PRO |
| Metal Oxide/Hybrid | CPUs, GPUs, application processors | 3-9 W/mK | Arctic Silver, Noctua* |
| Thermal Adhesive | Permanent heat sink fixing | 0.8-1.5 W/mK | MG Chemicals |

South African buyers can check real-time availability, reserve for in-branch pickup at Samrand, Pretoria CBD, or Cape Town, or request VAT invoices for project or procurement use.
When and Where to Use Thermal Compound
- Mounting CPU and GPU coolers (PC builds, industrial computers).
- Improving heat dissipation for power transistors, MOSFETs, and rectifiers.
- Thermal coupling of regulators, diode bridges, or LED modules to metal heat sinks.
- Repairing or restoring cooling interfaces on used or legacy boards.
Whether you're a maker, student, or professional technician, using the correct thermal interface ensures your electronics perform well in the often high-ambient conditions found in South African workshops and labs.

How to Select the Right Thermal Paste
Start by considering the application. For desktop CPUs/GPUs, prioritise high-conductivity pastes (over 3 W/mK) for demanding use. For standard power components, a general-purpose silicone or zinc oxide-based paste is typically suitable. If you require a lasting bond (mounting without screws), opt for thermal adhesives.
Application Tips for Best Results
- Clean both heat sink and component surfaces with isopropyl alcohol to remove oils or debris.
- Apply a small, even amount (about a grain of rice for CPUs) to avoid spillage.
- Compress surfaces firmly and evenly; secure with fasteners if non-adhesive paste is used.
- Avoid over-application, which can lead to insulating pockets and reduced thermal transfer.
Typical tubes found at Communica range from 1g (ideal for single board jobs or student kits) to industrial-size syringes for production environments.
Frequently Asked Questions
- Can I re-use thermal paste? It's recommended to clean and reapply fresh paste whenever remounting heat sinks for optimal performance.
- How long does stock last at normal temperatures? Most reputable brands maintain thermal performance for several years if properly applied.
- Are different pastes compatible with all surfaces? Most are safe for metals and ceramics, but check for potential conductivity if near circuit traces.
For bulk buyers, Communica supports account-based orders, project quoting, and provides VAT-compliant invoices for campus, SMB, or industrial needs.
