Don’t Block the Vents
Like people, desktop and laptop computers need to breathe.
The operative rule here is “don’t block the vents.” Just like people, machines need to breathe – though, in their case, it’s to ensure their insides remain cool enough to function properly.
If you have a desktop, keep the tower clear of any obstructions, like cabinets or walls. If it’s possible to do so securely, elevate it to ensure good airflow on both sides. For laptops, maintain a clear work space free from clutter that could obstruct airflow – for instance, papers or books. Periodically check that the fans are working as well.
No matter what kind of device you have, maintain adequate ventilation and reasonable climate control. You don’t have to blast the AC or leave the windows open in the winter, but setting the thermostat to 80 probably isn’t a great idea either.
