7 top rated Thermal Paste for every need: Australia's top picks!
Thermal paste, also known as thermal grease or compound, is a critical component in any computer or device utilizing a heat-generating component like a CPU or GPU. It fills the microscopic imperfections between the heat source and the heatsink, ensuring efficient heat transfer and preventing overheating that can lead to performance throttling, instability, and even permanent damage. Using high-quality thermal paste allows for optimal cooling, extending the lifespan of your components and enabling them to operate at their full potential, contributing to a smoother, faster, and more reliable computing experience.
What to Look For
Viscosity
A good thermal paste shouldn’t be too thin (leaking) or too thick (air bubbles). A medium viscosity allows for easy spreading and consistent contact.
Thermal Conductivity (W/mK)
This is the primary performance metric; higher values (typically 8 W/mK or greater for quality pastes) indicate better heat transfer capabilities. Be wary of unusually high values, which might indicate misleading marketing.
Electrical Conductivity
Ideally, thermal paste should be electrically non-conductive. Conductive paste can permanently short out components if it spills, so always double-check the product description and handle with care.
Composition/Ingredients
While specifics can be complex, generally, pastes with ceramic or metal oxide particles suspended in a silicone-based carrier fluid are common and perform well. Avoid pastes with questionable or unknown ingredients.
Application Method Recommendations
Reputable brands usually provide guidelines for application thickness and method (e.g., pea-sized dot, X pattern). Following these recommendations will help ensure optimal performance.
Reviews and Reputation
Check online reviews and benchmarks from trusted sources to gauge the real-world performance and reliability of different thermal paste brands and formulations.
- QUALITY: The design of our thermal paste packagings has changed several times, the formula of the composition has remained unchanged, so our MX pastes have stood for high quality
