If you live in a milder climate you may never have given this much thought, but in states like Nevada, Florida, Texas, or New Mexico the summertime heat can seriously affect electronic equipment. On a particularly warm day your laptop might become too hot to rest your hands on for typing. This isn't only a nuisance — it can cause long-term damage to components.
Identifying Overheating
If your operating system doesn't let you monitor internal CPU temperature, install a CPU temperature monitoring tool to keep an eye on it. Beyond that, there are some obvious signs your device is running too hot:
- Choppy, "glitchy" graphics — most obvious when playing games. When the framerate slows and looks like an old stop-motion movie, overheating is likely.
- Your device shuts itself off — many systems will automatically power down when the CPU temperature gets too high.
- Intense slowdown — when it takes several seconds to move the mouse cursor or open simple windows, overheating is a common cause.
Dealing With Overheating
Here are some of the easiest, practical ways to manage overheating on hot days:
- Double check your fans. Open the case and let the computer run; if fans aren't spinning it could be a loose wire or a failed fan. A desk fan can help temporarily until you replace internal fans.
- Keep the room cool. During the hottest months don't run a PC or gaming console in an uncooled room if you can avoid it.
- Keep a can of compressed air on hand. Dust inside a device acts like insulation and traps heat around components.
- Task manager — end unnecessary processes. Closing or uninstalling background programs reduces workload and heat. If you're unsure which processes are safe to end, look them up before stopping them.
- Work at cooler times. If your schedule allows, use your computer during the evening or early morning when ambient temperatures are lower.
If you use computers as part of a business or public venue, consider whether specialized coverage applies to your equipment, for example Theaters Insurance or Summer Camps with Horseback Riding Insurance, and talk to an agent about options for protecting gear against heat-related failure.
Frequently Asked Questions
How can I quickly cool a laptop that feels very hot?
Shut it down, move it to a cooler, well-ventilated area, and remove any obstructions to the vents; do not place it directly on soft surfaces like a bed or couch.
Can overheating permanently damage my computer?
Yes — prolonged high temperatures can shorten the lifespan of CPU, GPU, battery, and storage components.
Is it safe to use a laptop on my lap during hot weather?
Using a laptop on soft surfaces can block vents and trap heat; use a hard, flat surface or a laptop cooling pad to improve airflow.
When should I seek professional repair for overheating?
If fans are noisy or not spinning, temperatures remain high after cleaning and basic fixes, or the device repeatedly shuts down, have a technician inspect it.
