Thermal paste

Start by identifying safety, performance, and application needs across your devices. For broad compatibility and easy use, select a non-conductive option like ARCTIC MX-4 style pastes, which are described as safe and non-conductive and come in a 4 g tube with solid thermal conduction around 8.5 W/mK. If you’re after maximum cooling for demanding CPUs/GPUs, consider a high-performance option like LT-100 Liquid Metal, which offers ultra high thermal conductivity and supports cooling capacity up to 138 W. These contrasts help you match risk, ease, and payoff.

The most complex attribute is thermal conductivity and how long the paste maintains performance. Higher conductivity means better heat transfer from processor to heatsink, directly impacting temperatures under load. For example, non-conductive ARCTIC MX-4 style pastes deliver reliable performance and a long lifespan (up to 8 years in some descriptions), while a Liquid Metal option like LT-100 emphasizes peak conductivity and short-term performance for demanding tasks. Understanding this helps you balance everyday reliability with peak cooling when needed.

For desktops and multi-device setups, a 4 g tube of a non-conductive paste (like MX-4 style) is commonly used due to its safety and broad applicability, with easy application. For compact laptops or thinner CPUs where space is tight, smaller tubes (2 g options like MX-6) fit better and still provide solid conduction. Packaging options range from 2 g to multi-pack sets, making it easier to stock for several devices without compromising performance.

Apply the paste after cleaning the surface, aiming for a small, even spread. The standard steps described in several products are: first, clean the CPU/GPU surface; second, apply a pea-sized amount or a center-dab of the paste. This approach ensures even coverage without excess. Let the paste settle briefly before reattaching the heatsink to achieve consistent contact and thermal transfer across the processor die.

Yes, there are options formulated for higher performance. A high-conductivity paste like LT-100 Liquid Metal offers ultra high thermal conductivity and is designed for CPU/GPU cooling, enhancing heat dissipation for demanding workloads. It’s best suited for experienced users who can apply it carefully to avoid contact with other components. This contrasts with non-conductive pastes, which prioritize safety and ease of use for general applications.

Absolutely. You can choose packaging that fits multiple devices, such as 5-pack or 20-pack grey pastes, or 10-pack and 15-pack variants. These multi-pack options let you equip several CPUs and GPUs without needing new tubes frequently, ensuring you have consistent thermal material on hand for upkeep or upgrades across your computer fleet.
