Passively cooling graphics cards: A Radeon 7500 trimmed to be silent
To free your graphics card from the loud fan and the attached heat sink, you don't need a lot of tools:
- Antistatic cover (or plastic bag)
- Nail polish remover
The existing heat sink on the graphics card can actually be easily removed. You only need the few utensils mentioned above. If you try to remove the cooler, it will probably not be possible without violence. To protect the graphics card from damage, the card is simply packed in an antistatic sleeve. You can then put the whole thing in the freezer for a few minutes. Due to the low temperature, the thermally conductive adhesive becomes brittle, so that the cooler can be removed without problems.
The paper is required to protect the card from being damaged by the knife. The strip, which has been folded several times, is placed under the cooler in such a way that the knife cannot destroy any conductor tracks or other sensitive components. Well canmake slight lever movements from a few sides. The heat sink should actually be quite easy to pry off.
If you look at the graphics chip now, it is very likely that some thermal adhesive will appear (to my astonishment this was partially liquid on the Radeon 7500). This has to go down as it hinders future fastening and cooling. The best way to do this is to use nail polish remover. The last remains should be removed after a few seconds. In theory, the chip could now be ground flat. That doesn't make the cooling much better.
