Too many thermal pastes on the market claim to do a good job, but if the conductivity isn't up to par, you're basically investing in a dud. The downside? A high thermal conductivity might come from metal-based pastes, which can conduct electricity, potentially causing issues if it spills over components.

Viscosity

Viscosity, or thickness, plays a pivotal role too. It determines how easily the thermal paste spreads when applied. A paste that's too thick may not spread well and create air bubbles, and you don't want that in a place where maximum contact is essential. Conversely, if a paste is too runny, it might spread out of control, making for a mess inside your GPU.

In many ways, viscosity balances usability and performance. A mid-range viscosity can often foster straightforward application while still providing solid thermal transfer. But remember, if you have a higher-performance GPU, opting for a paste with slightly lower viscosity might help in ensuring the paste doesn’t clump and can form a tight bond with the heating surfaces.

Durability

Durability is the factor that ensures your thermal paste remains effective over time. A durable paste should maintain its properties without significant degradation and safeguard against crusting or cracking. Some thermal pastes have a lifespan ranging from a couple of years up to a decade, which can be a game-changer if you want to avoid frequent replacements.

A durable thermal paste often contains binding agents that resist breakdown. The trade-off here? Some longer-lasting pastes might take longer to cure initially, thus delaying your use of the GPU after application.
