Reasons for the excessive temperature of Win7 graphics card and countermeasures

Reason analysis:
1, the thermal grease on the graphics chip is missing or dry, poor thermal conductivity.
2. There is too much dust inside the computer mainframe, and the heat dissipation is not good.
3, the contact between the graphics chip and the heat sink is poor.
4, graphics card cooling fan power is insufficient, the speed is not enough.
Response measures:
1. Add some lubricating oil to the graphics card cooling fan, observe whether the graphics card cooling fan is running normally. If the fan does not turn damaged, re-purchase the new cooling fan to replace it.
2, clean the dust inside the chassis, the dust on the graphics card should be more important to clean. You can take a high-powered hair dryer to blow the computer inside the chassis for a while, or you can remove the accessories to clean them separately.
3, if the contact between the graphics chip and the heat sink is poor, you need to apply thermal silica gel, smeared between the fan and the graphics card core.
4, in order to reduce the internal temperature of the host, you can add a convection cooling fan on the chassis, so that the heat from the graphics card is quickly taken away.
