Laptop Overheating & Fan Noise Guides

Heat and fan noise go together. When the processor or graphics chip gets hot, the fans speed up, and when the cooling cannot keep up, the system slows itself down to protect the hardware. That throttling is why an overheating laptop often feels slow long before it shuts down. Common causes are dust in the vents and heatsink, an air intake blocked by a bed or sofa, a background process keeping the CPU busy, and power settings that favour maximum performance.

These guides explain how to read your CPU temperature in Windows, which readings are worth worrying about, how to find the process responsible for the heat, and which fixes are safe to do yourself, such as cleaning the vents, adjusting the power plan and trimming startup apps. They also explain which jobs belong in a repair shop, such as replacing dried-out thermal paste or a failing fan.

If the heat is coming from software, a technician can find and stop it remotely and tune the power and startup settings for you.
