Reasons for the excessive temperature of Win7 graphics card and countermeasures

Cause analysis:

1. The thermal grease on the graphics chip is missing or dry, and the thermal conductivity is poor.

2. There is too much dust inside the computer mainframe, and the heat dissipation is not good.

3, poor contact between the graphics chip and the heat sink.

4, graphics card cooling fan power is insufficient, the speed is not enough.

Countermeasures:

1. Add some lubricant to the cooling fan of the graphics card to observe whether the cooling fan of the graphics card is running normally. If the fan does not turn damaged, re-purchase the new cooling fan and replace it.

2. Clean the dust inside the chassis, and the dust on the graphics card should be cleaned. 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.
