Why is my MacBook constantly overheating?
Including running too many applications at once, using outdated hardware and software, dusty or blocked vents, or malware.
First and foremost, running too many applications at once can cause heat to build up in the system, as the CPU must work harder to switch between activities. Try closing any applications that you are no longer using to reduce the load on your system.
Another common cause can be the age of your hardware or the software, or a combination of both. Older hardware won’t be able to disperse the extra heat as quickly as a newer, more efficient model. Similarly, running outdated software can be more intensive on your system than the most up-to-date version.
In addition, if your vents are blocked by dust, the heat won’t be able to dissipate and will remain trapped in the laptop, leading to an increase in temperature. It can be beneficial to periodically check the vents on the sides and bottom of your MacBook and make sure they are free of dust or debris.
Finally, malware can be an issue as well. Malware and other malicious programs may be running unseen in the background, putting extra strain on your system and causing it to heat up. Run antivirus software and scan your system to ensure there are no malicious programs that may be the cause.
Ultimately, it’s important to identify the exact cause of your MacBook’s overheating before it leads to more serious problems.
