Thermal conductive paste and thermal conductive silicone pad is as a kind of auxiliary CPU heat dissipation material, maximize CPU fan cooling efficiency, what's the difference between the two? Which one is more effective?

Thermal conductive silicone piece of commonly used in some inconvenient coating thermal conductive paste, such as the host version of the power supply parts, host version of the power supply of calorific value is opposite bigger, but the machine part is not smooth, coated thermal paste is not convenient, can use of thermal conductive silicone pads for heat dissipation at this moment, in addition, under the video card heat sink, requires multiple components in contact with the card on the different parts, the thermal conductive silicone pads than thermal conductive paste more convenient to use.

Apart from the above reasons, the following is a list of the difference between the CPU thermal conductive paste and thermal conductive silicone pads:

Price: thermal conductive paste price is low, has been widely used. Thermal conductive silicone pads price slightly higher than the thermal conductive paste, often used in laptop computers, LED lighting and other thin precision electronic products.

Shape: it is thermal paste the condensate, thermal conductive silicone pads for sheet material.

Thickness: due to fill the gap of thermal conductive materials and thermal conductive paste is limited, the thermal conductive silicone mat thickness between 0.2 ~ 20 mm, application range is very wide.

Thermal effects: because the thermal conductivity of silicon membrane thermal resistance is small, under the same coefficient of thermal conductivity, thermal conductivity is better than that of silicon membrane of thermal conductivity of thermal conductive paste, therefore, in order to achieve the same performance of thermal conductivity, coefficient of thermal conductivity of thermal conductive silicone pads must be higher than the coefficient of thermal conductivity of thermal conductive paste.

Coefficient of thermal conductivity, the thermal conductivity of thermal conductive paste and thermal conductive silicone pads, and thermal conductive paste for 5 w/m.K, thermal conductive silicone pads of up to 12 w/m.K.

Insulation: because of the metal powder thermal conductive paste insulation performance is poor, thermal conductive silicone pad insulation performance is good, thickness is 1 mm H48-6 g thermal conductive silicone pads electrical insulation index above 13000 V.

Convenient: remove after assembly is not convenient to coating thermal conductive paste, thermal conductive silicone pad is convenient to install.

Use: thermal conductive paste should be carefully evenly (if large size hardware is not convenient to apply), easy to contaminate surrounding equipment, cause a short circuit and electronic components scratch; Thermal conductive silicone pads can be arbitrarily cut, tear protective film directly, tolerance is small, clean.
