This thermal paste works with a heat sink to improve heat dissipation from integrated computer chips such as CPUs. The thermal paste features CE and RoHS certifications so you can rest assured it's safe for its intended use. Reliable Performance This thermal paste, also known as silver grease, is a metal-based compound that contains 60% metal oxide to offer better thermal conductivity than standard heat transfer pastes. SILVGREASE1 ensures reliable performance in temperatures of -22°F to 365°F (-30°C to 180°C) with thermal conductivity of 3.195 W/m-K at 25 °C or greater. This performance makes the compound ideal for servicing & maintaining workstations, desktop computers and servers, and is best suited for CPUs with TDP of up to 65W Reseable 1.5g Syringe Tubes The tube contains 1.5g of paste, sufficient for 4 to 6 applications. the compound is packaged in a syringe for easy application, that's re-sealable to prevent the product from drying between use. SILVGREASE1 is backed by a StarTech.com 2-year warranty, including free lifetime 24/5 multi-lingual, North American based, technical assistance.
