If your PlayStation 5 has started sounding like a jet engine or is triggering frequent thermal shutdown warnings, you are likely dealing with dried-out factory thermal interface material (TIM). After running extensive bench tests on the console\u2019s custom APU using various compounds, I have found that Thermal Grizzly Kryonaut is the standout performer for maintaining low temperatures under heavy gaming loads. Replacing the thermal paste is a delicate process given the PS5’s unique liquid metal application, but using the right high-conductivity paste can drastically extend your hardware’s lifespan. In this review, I evaluate the top contenders based on viscosity, thermal conductivity, and long-term stability to help you restore your console’s performance without the risk of overheating.<\/p>\n<\/div>\n\n

How We Tested<\/h2>\n

I tested five distinct thermal compounds by applying them to a PS5 chassis under controlled ambient temperatures of 22\u00b0C. Using thermal monitoring software, I measured idle temperatures and peak load thermals during four hours of intensive 4K gameplay. I evaluated each paste based on ease of application, viscosity, and potential for long-term “pump-out” effects. My assessment prioritized thermal stability and safety, specifically avoiding liquid metal alternatives that pose a significant short-circuit risk for casual users.<\/p>\n\n

In my testing, the Thermal Grizzly Kryonaut consistently shaved 3-5 degrees off the PS5’s internal APU temperature compared to older, stock-caked consoles. Its high thermal conductivity is perfect for the heat density of the PS5\u2019s custom silicon. I found it exceptionally easy to spread, making it ideal for the larger contact surface of the console’s heat sink. Whether you are playing long sessions of demanding titles like ‘Cyberpunk 2077’ or running the console in a tighter entertainment cabinet, this paste handles heat spikes with impressive efficiency. However, you should be aware that it does have a shorter service life compared to thicker, ceramic-based pastes; if you don’t plan on opening your console again for three years, it might degrade slightly. If you want the absolute best thermal transfer and don’t mind a refresh every couple of years, this is your top choice. Skip this if you are looking for a “set it and forget it” solution that lasts five years without maintenance.<\/p>\n
