Luckily, the fix is simple: Schedule regular cleaning sessions where you use a can of compressed air to blow dust and pet hair off your cooling-fan blades and out of your case. This goes for laptops and desktops alike.
The easiest way to keep this resolution is to set a recurring reminder in your calendar. I recommend performing this kind of cleaning every three months.
