Introduction

Like all graphics cards, the Radeon X1900 XTX occasionally needs to be opened up and cleaned in order to function properlly.

Once you remove the heat sink, you'll need to reapply thermal paste to the GPU die. Follow our Applying Thermal Paste Guide for detailed directions.

  • Seperate the heatsink and the card.

if you're doing this on a Mac, you have to take out the two small screws on the dvi connection end and loosen the dvi connection nuts so the heatsink will separate.

  • Re-Applying Thermal Paste:

  • Apply a small glob of thermal paste to the corner of the die, (I recommend using Arctic Silver 5) and use an index card to spread a thin, even layer of it over the surface of the chip.

  • For more detailed directions, follow our Applying Thermal Paste Guide.
