Minute spark and odor during PC cleaning with a hair dryer
Disconnected power from the PC and pressed the power button to discharge capacitors. Used a hair dryer at room temperature to blow air inside the case—mistake, as expected—and made the fans spin. While doing so, I noticed a faint spark near the motherboard and processor cooler, and when I got close it smelled slightly burnt. After waiting 30 minutes, I restarted the PC. Everything functioned normally during a benchmark test and a game session lasted ten minutes without any issues. It appears the damage might have been minor, possibly from a small plastic piece on a fan.
Hair dryers release a lot of static electricity through the end used to blow air. It could be due to a few things—maybe a short circuit, prolonged contact with metal, or quick movement around the device.
In a broad region and at a single location for several seconds, particularly near the fan to induce rotation and increase dust expulsion
They don't generate powerful suction (I use a Dyson styling tool).
