Laptop Cooling Fan – Description

🔧 What It Is:

A laptop cooling fan is a small, high-speed fan inside your laptop (or externally in a cooling pad) designed to keep your internal components — especially the CPU and GPU — at safe operating temperatures. It’s an essential part of the laptop’s thermal management system.

📦 Types of Laptop Cooling Fans

📋 Key Features of Internal Cooling Fans

💡 Why It’s Important

Prevents Overheating: Keeps the CPU/GPU under safe thermal limits

Improves Performance: Prevents thermal throttling (slowing down due to heat)

Extends Lifespan: Overheating can damage chips, battery, and motherboard

🛠️ Common Signs of Fan Issues

Loud whirring or grinding noise

Frequent overheating or shutdowns

Fan not spinning or air not blowing from vent

BIOS or system alerts (e.g., “Fan error” at boot)
