If your laptop is unusually hot, slowing down, or shutting off, start by turning it off and giving it time to cool. Check its airflow and reduce unnecessary workload before buying a cooling accessory. A little warmth under load can be normal; repeated heat-related shutdowns are not.
This guide focuses on Windows laptops, but the airflow and safety tips apply broadly. Vent locations and maintenance instructions differ by model, so consult the manufacturer’s guidance for your laptop.
Stop using the laptop if it is unusually hot, has shut down repeatedly, or shows signs of damage. Shut it down and disconnect power if safe, then let it cool on a hard, nonflammable surface away from combustible materials. Do not put it in a refrigerator or freezer.
If you notice a bulging case or trackpad, a suspected swollen battery, unusual odor, smoke, or hissing, stop using and charging the device. Do not press on, puncture, or attempt to remove a swollen battery. If smoke or fire is present, move away and contact emergency services. Otherwise, contact the manufacturer or a qualified repair technician. See Microsoft’s battery safety guidance.
A laptop can become warm and its fan can speed up during gaming, video calls, updates, or charging. These signs alone do not prove a fault. More concerning signs include persistent excessive heat while idle, unusually loud or nonworking fans, major slowdowns, heat warnings, and repeated unexpected shutdowns. Other problems can also cause shutdowns, so heat is not the only possible explanation.
Once the laptop has cooled and there are no damage or battery warning signs, try the steps below. Save your work frequently while troubleshooting.
Place the laptop on a hard, flat surface with its ventilation openings unobstructed. A blanket, pillow, carpet, or your lap can block openings. Check the sides, rear, and underside; vents differ by model. Leave room around them according to the laptop’s manual, and avoid direct sunlight or a hot room.
For external-monitor setups, see our guide to using a laptop with the lid closed and check your model’s ventilation guidance. A properly sized ventilated laptop stand may help keep vents clear, but it is optional and cannot repair a failing fan. Make sure the stand does not cover the vents or make the laptop unstable.
Shut down the laptop, unplug its charger and accessories, and allow it to cool. Look for dust at the vents. Follow the cleaning instructions for your specific model. If the manufacturer recommends canned compressed air, use it as directed, including the recommended distance and short bursts; do not insert objects into the vents or use liquids. Do not open the laptop unless you are qualified and following the manufacturer’s service instructions.
Dell recommends powering off and disconnecting the computer before cleaning, and cautions against vacuum cleaners or blowers near components. See Dell’s overheating and vent-cleaning instructions. If dust is trapped inside or the fan seems faulty, arrange professional service.
After the laptop has cooled, close applications and browser tabs you are not using. Press Ctrl + Shift + Esc to open Task Manager, then check which familiar apps are using substantial CPU resources. Save your work before closing an app. Avoid ending unfamiliar system processes, and remember that updates or security scans may temporarily use more resources.
If heat rises only during a demanding game or video-rendering task, reduce the workload or take a break. Heat and fan noise can increase during demanding activity, but persistent shutdowns still warrant investigation.
In Windows 11, open Settings > System > Power & battery and review the available power mode. A balanced or efficiency-oriented mode may reduce heat at the cost of some performance; options vary. Install available Windows updates, and use your laptop maker’s official support site or approved update tool for model-specific drivers and firmware.
Follow the manufacturer’s instructions for any BIOS or firmware update. Do not interrupt an update or install firmware intended for another model. If you are unsure, ask the manufacturer or a qualified technician.
A cooling pad can help some laptops by improving airflow, but results vary with the laptop’s vent layout, pad design, and environment. It is not a substitute for clearing blocked vents or repairing a faulty fan. Look for a stable pad sized for your computer, with fans positioned where they can help rather than obstruct airflow.
Compare laptop cooling pads after checking your laptop’s size and vent placement. Avoid assuming that a more powerful-looking accessory will fix a hardware problem.
Contact the laptop maker or a qualified technician if the computer continues to overheat after airflow and workload checks, shuts down again, displays a thermal or fan error, or has an abnormal fan noise. A failed fan, internal dust, or another hardware fault may require service. Do not continue restarting a device that repeatedly shuts down from heat. Back up important files when it is safe to do so.
Yes. Laptops often get warm during demanding work or charging, and fans may speed up. Unusual persistent heat, repeated shutdowns, or signs of physical damage need further attention.
It may improve airflow for some setups, but it cannot reliably fix a broken fan, obstructed internal cooling system, or battery problem. Check the cause before buying.
No. Rapid cooling can create condensation. Turn it off, unplug it if safe, and allow it to cool naturally on a suitable hard surface.
Start with safe cooling, unobstructed vents, and a manageable workload. If overheating or shutdowns continue, seek qualified help rather than relying on an accessory. Stop using the device immediately if you suspect battery swelling or other physical damage.
