Specification: Material: thermal grease Size: about 14cm/5.51" in length Net content: 1g Thermal conductivity: 4.8W/M-K Density: 2.3g/cm Working temperature: -50-200 Color: gray Application range: used for heat dissipation of CPU, GPU, MOS tube, LED light, thermostat Working principle: Fill the gap between the heating element and the cooling device; increase the contact area to achieve the best heat conduction effect. How to use: A small amount of silicone oil floating on it is normal. Please stir well before use. Keep the coating surface clean and apply directly with tools (such as scrapers, finger cots, etc.). Storage: Store at room temperature. Note: Keep children away from it. If swallowed or accidentally get into the eyes, ears, nose, mouth, please rinse with water or send to the hospital if necessary. Please cover it after use to avoid impurities such as dust that have an adverse effect on thermal conductivity. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement.
