Guide :- Cleaning Your Graphics Card

Before you begin, proper tools are required - 

  • screwdrivers
  • cleaning materials such as canned air, alcohol, cotton swabs, and replacement thermal paste.
  • small brush to wipe away additional dust and old thermal interface material but that is optional

Disassemble Your Card

RevitalizeGraphicsCard--Unscrew Back

Removing the screws holding the card’s rear heat/reinforcement plate in place.

Remove the small screws that hold the spring-loaded heat sink mount.

Gently pry the reinforcement plate off the card, using steady, even pressure. You should use the same technique for the fan shroud and heat sink. You might have to unplug the cooling fan from a port on the PCB.

Clean and Reassemble Your Card

RevitalizeGraphicsCard--Thermal Paste

1. Apply fresh thermal paste in all the places you used to remove it. Make sure you use the least amount of paste necessary to produce a complete layer over the surface of the chip you’d like to cool.

2. On the Radeon HD 7970 Card – and most other cards – a metal clip with four springs attaches to the heat sink over the GPU. Over time, the clip and the four springs can become deformed, which lowers the contact pressure to the GPU and makes your card run hot. In order to fix that, carefully flex the bracket upward and slightly stretch the springs back out.

3. With the bracket and springs stretched out, reattach the heat sink to the GPU. Make sure that the heat sink is making good, complete contact with the GPU. Screw in the spring-loaded mount.


4. Screw together the case bracket to the fan shroud.

5. Screw the card’s rear reinforcement plate back on.

Update Software

Go to the manufacturer site to see if there are updates for the vBIOS and drivers.

Select the exact model of your computer’s graphics card (you can find this in the Device Manager window).

If there are updates available, follow the instructions that the manufacturer provides. Following the manufacturer’s instructions is particularly important for flashing the vBios.
