Last updated November 9, 2026

To stop a laptop from overheating, use it on a hard, flat surface and keep the vents clear. Close heavy apps, clean out dust and keep the room cool.

A warm laptop is normal, but a very hot one can slow down, shut off or wear out faster. This guide explains why laptops overheat and how to fix it step by step.

Key Takeaways

Soft surfaces like beds and couches block airflow and trap heat.
Most laptop makers list a room range of about 10 to 35 degrees Celsius.
Heavy tasks like games and video editing make fans run faster.
Dust in vents and fans is a common cause of overheating.
If a laptop shuts down from heat, let it cool for several minutes before restarting.

How Hot Is Too Hot?

Laptops get warm during normal use. Microsoft notes that its devices may feel warm. It lists an operating range of 0 to 35 degrees Celsius.

Apple lists an operating range of 10 to 35 degrees Celsius for its laptops. Its guide to acceptable operating temperatures explains the details.

35Degrees Celsius, the top room temperature for Mac laptops, per Apple Support.

Warning signs

The fan runs loudly all the time
The bottom feels too hot to touch
Apps freeze or the laptop slows down
The laptop shuts off suddenly
A thermometer icon or heat warning appears

If the device gets too hot, it may shut down to protect itself. Microsoft says to turn it off and move it somewhere cooler. Its warm device guide says to let it cool for at least five minutes.

Why Laptops Overheat

Using the laptop on a bed, pillow, couch or lap
Blocked vents
Dust built up inside the fans
Heavy tasks like gaming, video editing or many browser tabs
A hot room or direct sun
Old thermal paste or a failing fan

Apple warns against using its laptops in bed, on a pillow or under bedding. Soft surfaces cover the vents and trap heat.

Good to know. Never leave a laptop in a parked car. Apple says the temperature there can go beyond the safe range.

Quick Fixes That Work

1. Move to a hard, flat surface

A desk or table lets air flow under the laptop. Apple notes fans may run more on a couch, bed or lap.

2. Clear the vents

Make sure nothing blocks the openings on the sides, back or bottom. Do not place objects on the keyboard while the laptop runs.

3. Close heavy apps

Quit apps and browser tabs you are not using. Every open program adds work for the processor.

4. Cool the room

Move away from heaters and sunny windows. A cooler room helps the fans work less.

5. Restart the laptop

A restart clears stuck processes that may keep the processor busy. Apple suggests restarting newer Macs if the fans run fast without heavy use.

Software and Settings

Find what is using power

On Windows, open Task Manager to see which apps use the most processor time. On a Mac, open Activity Monitor.

End or uninstall programs you do not need. Some apps keep running in the background without you noticing.

Use a balanced power mode

Windows and macOS offer power settings that trade a little speed for less heat. Try a balanced or battery saver mode.

Install updates

System and driver updates can fix bugs that cause high processor use. Turn on automatic updates.

Scan for malware

Hidden malware can run the processor hard and create heat. Run a trusted security scan.

Clean the Vents and Fans

Dust is one of the most common causes of overheating. It builds up in vents and fan blades over time.

Turn off and unplug the laptop.
Use short bursts of compressed air into the vents from an angle.
Hold the can upright and keep it a few inches away.
Wipe the outside with a soft, dry cloth.

Do not open the case unless you know how, since it may void the warranty. A repair shop can clean the inside safely.

Quick tip. Clean the vents every few months, more often if you have pets or a dusty home.

Helpful Accessories

Laptop stand

A stand lifts the laptop and improves airflow. It also raises the screen to a better height for your neck.

Cooling pad

A cooling pad has built-in fans that push air under the laptop. It can help during gaming or long video calls.

Lap desk

If you must use the laptop on your lap or couch, a hard lap desk keeps the vents open.

Gaming and Heavy Work

Games, video editing and 3D design push the processor and graphics chip hard. Fans will run faster, and Apple calls that rushing-air sound normal in its guide to fans and fan noise.

Lower graphics settings and cap the frame rate in games to reduce heat. Plug in the charger for best performance, but keep the vents clear.

Battery and Heat

Heat wears out laptop batteries faster. Keeping your laptop cool helps the battery last longer too.

Working in Hot Weather

Summer heat makes overheating more likely. Work in the coolest room you can and keep blinds closed against direct sun.

Avoid working outside in full sun for long periods. Shade helps, but the air may still be too hot for the laptop.

Give the laptop breaks during heavy tasks on very hot days. Short pauses let the fans catch up.

Browsers and Video Calls

Web browsers can use a lot of power, especially with dozens of tabs. Close tabs you do not need and remove extensions you never use.

Long video calls work the processor and camera hard. Turn off your video when you do not need it, and close other apps during the call.

Overheating Myths

Myth one, the freezer will cool it fast

Never put a laptop in a freezer or fridge. Moisture can form inside and damage the parts.

Myth two, loud fans mean it is broken

Fans often get loud during heavy work. That is usually the cooling system doing its job.

Myth three, a hot laptop is always dangerous

Warm is normal. Watch for warning signs like shutdowns, swelling or burning smells instead.

School Laptops and Chromebooks

Students often use laptops on beds and couches. A cheap lap desk or tray can make a big difference.

Remind kids to shut the laptop down before packing it. A running laptop inside a backpack can get very hot.

When to Get Help

See a technician if the laptop keeps shutting down or the fan makes grinding noises. A fan that never runs at all is also a warning sign. These can point to a failing fan or other parts.

Stop using the laptop if the battery swells, smells strange or gets extremely hot. These can be safety risks.

Microsoft advises contacting support if the overheating icon keeps appearing.
