I just burned my graphics card, replaced it with the same model and it is getting very hot again(>70°). It is passive cooled, I repaired PC case airflow but am afraid it might overheat again. It's a Gigabyte GV NX84S512HP with Nvidia 8400 GS.
- Are 90°C OK for GPU idle? What is the maximum?
- How Can I test PCIe voltage in order to decide whether to throw away the mainboard or Power supply?
