We know how frustrating it can be when your laptop runs hot or even overheats after only light use.
It’s often due to blocked airflow, heavy workloads, or just the natural wear and tear that comes with time. You’re not alone in this.
Laptops are compact machines packed with powerful CPUs and GPUs, so they naturally generate heat.
If vents get clogged or fans can’t keep up, temperatures spike.
According to HP’s tech guide, common culprits include intensive processing tasks, blocked air vents, dust buildup, worn-out thermal paste, and hot ambient conditions.
There are many steps you can take to keep your laptop cool. We outline effective ways to prevent laptop overheating below in this guide.
High Level Signs Laptop Overheating
Anything that adds heat or slows cooling can send your laptop into “overheat” mode. It helps to know how to tell when your laptop is overheating.
One obvious sign is unusually hot surfaces – if the keyboard or base feels like a pan, that’s a red flag.
Loud, constant fan noise or unexpected shutdowns also signal trouble.
When the CPU or GPU hits high temperatures, the system may throttle performance or shut off to protect itself.
In practice, if your laptop is slowing down, showing errors, or shutting down during normal use, consider that overheating may be the cause.
Quick Fixes for an Overheated Laptop
If your laptop is already overheating, act fast. First, power down and unplug.
Let it cool for a bit – sometimes a few minutes of rest can help reset thermal levels. Then try these easy steps.
1. Clean the Air Vents and Fans
Most laptops have intake vents on the sides or bottom.
Dust and pet hair easily clog these vents over time, starving the fans of airflow.
Use a can of compressed air (or a small vacuum) to blow dust out of the vents.
If you’re comfortable opening the case, gently remove interior dust from the CPU and fan assembly.
Clearing vents regularly is key: dust and debris can cause fans to struggle and heat to build up.
2. Elevate or Support the Laptop.
Laying a laptop flat on a desk is better than on a pillow or your lap.
Even better, prop it up: tilt the back slightly higher than the front.
Elevating the rear improves airflow under the laptop. (One DIY trick: place a small book or a strip of wood under the back feet.)
A solid lap desk or stand can serve the same purpose, preventing vents from blocking.
Australian summers can be hot – working on a metal table outdoors may feel pleasant but be mindful that direct sun can heat the chassis even more.
3. Use a Cooling Pad.
A laptop cooling pad (an external pad with built-in fans) can help a lot.
These pads blow cool air at the laptop’s vents or lift it up for better air circulation.
In tech tests, using a well-aligned cooling pad often drops temperatures a few degrees.
HP’s advice highlights that cooling pads boost airflow and reduce load on the laptop’s own fans.
Even a simple USB-powered pad can make a noticeable difference during gaming or video editing.
4. Adjust Power Settings
Sometimes the fix is software-based.
Under Windows (or Mac’s Energy Saver), select a balanced or power-saving mode instead of “High Performance.”
In Windows’ advanced power options, lowering the maximum processor state to 90 to 99% disables extra turbo boost that generates excess heat.
This trades a bit of peak speed for significantly lower temperatures.
Also, close any heavy background apps (web browsers with many tabs, games, or video software) that may be churning the CPU or GPU.
Shutting down unnecessary startup and background processes “drastically reduces” CPU load, helping the laptop stay cooler.
After doing these quick fixes, you should notice the laptop’s fans calming down and the case cooling off.
If it still shuts off randomly or feels scalding, there may be deeper issues. In that case, let’s look at long-term solutions.
Preventing Laptop From Overheating (Good Habits and Maintenance)
The best defense against overheating is regular care.
Make these habits part of your routine.
1. Keep Vents Clear.
Never block vents.
Avoid using the laptop on soft surfaces (beds, couches or your lap). These surfaces conform around vents and trap hot air.
A rigid desk or table is ideal. If you must use it on a couch or blanket, put a hard book or a riser underneath.
2. Clean Internally Periodically.
Every few months (or more often in dusty environments), use compressed air on the vents or open the panel to dust the fan.
Laptop internals attract a lot of dust. Regular maintenance… improves airflow and prolongs the lifespan” of components.
If you’re not comfortable disassembling it, a tech repair shop can do a quick clean for a small fee.
3. Update Software and Drivers.
Keep your system software up to date.
Driver and BIOS updates often include efficiency improvements.
For example, a BIOS update can “boost power efficiency by reconfiguring motherboard power settings”.
Likewise, graphics drivers or system utilities might optimize thermal management.
In Windows, check Windows Update and your laptop manufacturer’s support site (HP, Dell, etc.) regularly for firmware updates.
4. Watch Your Workload.
High-CPU tasks (gaming, video editing, large data crunching) naturally heat up the laptop.
When doing those tasks, ensure you’re in a cool room (if possible, use air conditioning or a fan).
Take breaks on long sessions – even pausing your work can give the cooling system a rest.
Consider closing browser tabs or non-essential apps while gaming.
Avoid letting intense processes run unchecked, and use browser extensions (like Flash blockers) to prevent heavy auto-playing videos
5. Stay Out of Direct Sun and Heat.
Ambient temperature matters.
Australian homes can get very warm in summer, and a laptop will heat up faster in a 35°C room than a 20°C one.
Never leave your laptop in a hot car or under direct sunlight, where heat soak can degrade the battery and chip performance.
Find a shaded, cooler spot to work or let it rest.
By combining these practices – clean the fans, keep vents free, and manage how you use the machine – you prevent most overheating issues.
In fact, many manufacturers explicitly recommend clean vents, flat surfaces, and cooling accessories as first-line defense
External Cooling and Hardware Checks
Beyond habits, there are a few more solutions.
1. Cooling Stands and Pads.
We mentioned cooling pads earlier.
Similarly, adjustable stands with fans or heat sinks can help. For example, if you frequently game or edit video, a multi-fan pad targeted at the vents can shave off extra degrees.
Even passive stands (like metal or plastic risers) elevate airflow. The HP tech blog suggests aligning pad fans with the laptop’s intake vents for maximum effect.
2. Control Fan Speed (Advanced).
Some laptops allow manual fan control via BIOS settings or software (like SpeedFan for Windows).
If your fans aren’t spinning up fast enough, you can set them to be more aggressive.
But beware: forcing fans to max speed all the time will drain battery and produce more noise. Use this only if needed.
3. Hardware Inspection.
Persistent overheating might indicate a hardware fault.
If cleaning and settings didn’t help, the internal cooling components could be failing. For instance, a fan might have stopped working, or the thermal paste between the CPU and heatsink could have dried out.
If you hear grinding noises from the fan or find it barely spinning, it may need replacement.
Reapplying fresh thermal paste can restore cooling efficiency (though that requires disassembly or a professional service).
To check deeper issues, manufacturer tools can help.
HP’s Support Assistant and Dell’s Hardware Diagnostics (built into their laptops or available online) can run tests on fans, sensors, and battery.
These tests can flag a failing fan or battery that’s getting too hot.
If your laptop is still under warranty or service plan, contacting the maker’s support (HP, Dell, ASUS, etc.) may resolve hidden issues.
Conclusion
Check your manufacturer’s support pages for model-specific guidance.
With a little care, you can tame an overheating laptop and keep it running smoothly.
Regular cleaning, smart usage, and the right accessories make all the difference.
In my case, even a modest cooling pad and keeping the laptop off my bed at night made it run significantly cooler.
Try these tips – your cooler laptop will work faster, last longer, and be less of a worry on those hot days.

FAQs
Why does my laptop overheat so easily?
Modern laptops are thin and powerful, so heat naturally builds up. Overheating usually happens if airflow is blocked (dust or soft surfaces), if you run demanding software, or if the cooling system is weakened (old thermal paste or a dying fan). High room temperatures also worsen it.
Why is my laptop running hot all the time?
This can be a sign of constant heavy CPU/GPU use, or something stuck in the background (like an update running, a browser with many tabs, or even malware). Check Task Manager (Windows) or Activity Monitor (Mac) for any runaway processes and close them. Also ensure vents are clean and fans spinning.
How do I stop my laptop from overheating?
Start by ensuring good ventilation: use a desk, keep vents clear, and clean dust. Use a cooling pad or stand. On software side, lower your power settings (e.g. switch to “balanced”), close unnecessary apps, and update your drivers. These steps collectively stop overheating in most cases.
Is overheating dangerous for my laptop?
Yes, long-term overheating can damage components. CPUs and batteries degrade faster in heat, and silicon chips can be permanently affected. That’s why laptops will throttle performance or even shut down at high temps. Address overheating promptly to avoid lasting harm.
My HP (or Dell) laptop is overheating – any specific tips?
The general advice still applies keep the vents clear and surface hard and flat. HP’s site, for example, recommends good ventilation and regular fan maintenance for Windows laptops. Dell users can use the Dell Power Manager app (Windows Store) to select a cool thermal profile, or limit Turbo Boost via power settings as a quick fix.
