Computers can overheat for many reasons, here are a few:
- Dust clogging up the fans and heat sinks (common in households with pets or smokers)
- Broken fans (fans have moving parts which wear out over time)
- Obstructed air vents (common with laptops that aren’t placed on a hard flat surface)
- Over clocked CPUs (common with gamers who want to get the best speed out of their computer)
- Dry or missing thermal paste (thermal paste allows the heat to transfer from the CPU to the heat sink)
Whatever the reason, an overheating computer can be an irritation at least and a real safety hazard at worse! Here are some of the symptoms:
- Loud fan noise (computers speed up the fan to cool the CPU)
- Slow computer (computers reduce the speed of the CPU to cool and protect themselves)
- Crashing, freezing or turning off (computers will often just switch off when they become too hot, but not always)
- Damage to the motherboard, CPU or other components which often breaks the computer
The photo shows damaged capacitors on a motherboard which was directly caused by an overheating CPU (from a dust clogged fan). This motherboard stopped working and had to be replaced. The capacitors (purple cylindrical components) in the middle have burst which you should be able to spot if you compare them to the capacitor on the right.
