GD900 selects much more tiny particle diameter metal oxide as the main raw materials, used for filling the gap between the heat source and heat sink device. Its outstanding performance on the CPU GPU LED will meet your high standard demand for cooling system. Product features: Accord with RoHS and REACH environmental protection requirements. High thermal conductivity, high insulation, high temperature resistant, low oil separation, non-. Working principle: Filling the gap between heating elements and the cooling device; Increasing the contact area so as to achieve the soundest thermal conductivity effect. of use: It's normal phenomena if there is little silicone oil floating above. Please stir well before use. Keep the coated surface clean and apply directly with tools (such as , finger , etc). Warm notice: Keep children from it. If it is swallowed or inadvertently come into eyes, ear, nose, mouth,please flush with clean water or send to hospital when necessary. Color: Gray Specific Gravity: 2.3 G/Cc Net weight: 30g Thermal Conductivity: 4.8 W/M-K Operating Temperature: -58~392 Degrees Fahrenheit Storage: Preservation at normal temperature. Please after used, avoiding impurities such as dust, that have a effect on thermal conductivity. Smearing Steps 1. Please clean the surfaces of heat source (CPU) and dissipate heat device (heat sink) with dry tissues. 2. Using or other tools to smear the onto the CPU, and it's no need to smear on heat sink. 3. The should be smeared evenly on the whole CPU surface. It can neither too thin, the words on it should be covered. Nor too thick, the thickness like A4 paper will be better.
