Both can depend on the laptop heat dissipation design heat dissipation patch used: when the CPU and GPU chip height is not the same, the main height. Another variation is attached to the memory or power supply. (Many friends, changed the GPU silicone grease, but forgot these parts) With ordinary silicone grease components, excellent silicone grease has a better thermal conductivity effect, and it is better to fill the gap between the chip and the radiator. There is a big difference between the effect of silicone grease and silicone grease, and secondly, some models themselves are weak in heat dissipation, so the change of silicone grease can not improve much.
