Does your laptop sound like a fighter jet while the keyboard starts to burn your fingers?
When temperature rises, the computer reduces its power to avoid damaging its own components. If you do nothing, a thermal crash may follow. Start by checking your PC temperature to confirm that the machine is actually overheating.
You do not have to wait for a forced shutdown. Here are the immediate steps you can take with what you have at hand.

Raise your laptop to let air circulate underneath
Raising a laptop is one of the simplest and most effective ways to lower the temperature quickly. Place it on a surface that leaves space between the chassis and the desk, such as two books or a stand. This improves airflow underneath the machine and helps the internal fans remove heat, especially when the vents are located below the computer.
This small change can lower temperatures by several degrees during long sessions or in a hot room. For regular use, a ventilated stand with built-in fans can reinforce the airflow, but simply avoiding a flat surface already limits overheating.
Switch to power-saving mode to reduce heat
Enabling power-saving mode limits processor performance and reduces the activity of some components, which automatically lowers heat production. It is useful for office work and browsing, where full power is unnecessary.
Work in a cool, shaded place
Ambient temperature plays a major role in laptop cooling. Working away from direct sunlight and other heat sources naturally limits the temperature rise. Moving to a better-ventilated or cooler room can lower temperatures by several degrees.

A cooling pad places fans beneath the computer and pushes cool air toward the chassis. It is particularly useful for gaming, video editing, and other demanding workloads. A good pad can lower CPU or GPU temperatures by several degrees and reduce thermal throttling.
Turn the computer off to lower its temperature
When a laptop is severely overheated, turning it off for a few hours remains one of the simplest and most effective solutions. A complete shutdown cuts power to the circuits and allows every component to return to a normal temperature, unlike sleep mode.
Replace the thermal paste to gain up to 10°C
Over time, thermal paste between the CPU and cooling system dries out or cracks. Heat dissipation becomes less effective, fans run faster, and performance drops. Replacing the paste can restore normal temperatures on an aging laptop, but the operation requires partial disassembly and care.
Blow compressed air through the ventilation grilles
Dust blocks the ventilation system and restricts airflow. Turn off the computer, hold it at a slight angle, and use short bursts of dry compressed air without turning the can upside down. Repeat this preventive cleaning every two or three months in dusty environments.
Open the laptop to clean fans and heatsinks
When external solutions are not enough, open the computer to reach the fans and heatsinks. Dust can form thick layers that prevent hot air from escaping. Use an antistatic brush and a suitable blower, avoid touching sensitive components, and ask a technician for help if you are not familiar with laptop hardware.

Replace a defective or underpowered fan
A worn or defective fan can cause persistent overheating even after cleaning. Choose a replacement compatible with the exact laptop model, connector, dimensions, and speed. If overheating continues, professional inspection is the safest option.
