If a computer fan stops working, it can lead to overheating issues that impact system performance and may eventually cause hardware damage. Here’s what could happen:
- Increased Temperature: Without proper cooling, components like the CPU, GPU, and power supply may start running at higher temperatures.
- Throttling: To avoid damage, many systems automatically slow down (throttle) the CPU and GPU when temperatures get too high, which decreases performance.
- Random Shutdowns or Reboots: Some computers are programmed to shut down when they reach critical temperatures to prevent hardware damage. This can lead to sudden shutdowns or reboots.
- Potential Hardware Damage: If overheating continues, it can damage internal components, particularly the CPU, GPU, and motherboard. Prolonged exposure to high temperatures shortens the lifespan of these components. Related: Will CPU overheating cause a computer crash?
- Data Loss: If the computer shuts down unexpectedly due to overheating, any unsaved data may be lost.
If a fan stops working, it’s best to address the issue as soon as possible, either by cleaning dust from fans and vents, checking for loose connections, or replacing the fan if necessary.
