My graphics card overheats or shows artifacts
Dried paste, worn pads, fans: I do a repad and repaste of your graphics card to get normal temperatures back.
Graphics card too hot, noisy, or picture glitching?
Soaring temperatures, fans at maximum, screen crashing in games, coloured dots and squares (artifacts): these symptoms almost always have a repairable cause.


The causes
- Dried thermal paste on the graphics chip
- Worn thermal pads that no longer cool the memory (VRAM)
- Clogged fans or damaged fan cable
- More rarely: faulty chip or memory
My repair
- Repad with Gelid pads, at the right thickness
- Repaste with Kryonaut
- Full cleaning, cable and fan repair
See the NVIDIA and AMD graphics card repair page.
