This product has high thermal conductivity, high insulation, high temperature resistance, will not dry out after long-term exposure, is not easy to volatilize, non-toxic, odorless, and non-corrosive.Product color: grayThermal conductivity: >1.93 Thermal impedance: <0.211Operating temperature range: -30~180Product weight: 25gQuantity: 5 piecesHow to effectively cool down: Scrape off the original dry thermal paste of the CPU and wipe it clean with a napkin, including the one on the cooling fan. At the same time, clean the dust in the heat sink of the cooling fan. After cleaning the dust on the fan, apply a thin layer of our store's thermal paste on the CPU. Be sure to apply it evenly and apply it all in place. Install the cooling fan to effectively cool down. Otherwise, the customer's method is wrong, resulting in failure to cool down.Friendly reminder: Most ordinary thermal conductive silicone greases will "dry" or "harden" after being used for half a year or more, which greatly affects the heat dissipation effect. Therefore, to ensure long-term and stable operation of the system, regular cleaning and re-applying of silicone grease is also necessary.
