This 5-Pack of thermal paste works with a heat sink to improve heat dissipation from integrated circuits (ICs), like CPUs, GPUs & other computer chips. The thermal paste features CE & Ro HS certifications so you can rest assured its safe for its intended use. High-Performance Thermal Paste The thermal paste, also known as silver grease, is a metal based (metal oxide) compound that contains 50% silicone, 30% carbon & 20% metal oxide to offer better thermal conductivity than standard heat transfer pastes with negligible electrical conductivity. The thermal paste/glue is suitable for operation in temperatures of -22°F to 365°F (-30°C to 180°C) with thermal conductivity of 3.07 W/m-K at 25 °C or greater. This performance makes the compound ideal for servicing & maintaining workstations, desktop computers & servers. Conveniently Sized 1.5g Tubes Each tube included in this five pack contains 1.5g of paste, sufficient for 4 to 6 applications, for 20 to 30 applications in total. Each unit is packaged in a syringe for easy application, thats re-sealable to prevent the product from drying between use. Plus, five included units make it ideal for distribution to different workstations throughout the work place.
