01.What is Airflow and why does it matter?
**Airflow** is the science of moving air inside your PC. If hot air gets "trapped" inside the case, your processor and graphics card fans will only circulate hot air, causing temperatures to rise to safety limits. When this happens, the PC reduces speed (Thermal Throttling) to avoid burning out, and you feel the stutters in your game.

02.1. Fan Positioning
Almost all fans blow air to the side where the 'grill' or manufacturer's sticker is. Follow the rule:
- Front and Bottom (Intake): Pull cold air from outside to inside.
- Back and Top (Exhaust): Push hot air from inside to outside.
- Remember: Hot air naturally rises. Therefore, the top fans should always be exhaust fans.
03.2. Positive vs Negative Pressure
The Secret Against Dust:
The ideal for gamers is Positive Pressure. This happens when you have more fans blowing air in than out. This forces air (and dust) to leave through all the case's cracks, preventing dirt from entering through unfiltered holes.
04.3. Glass Cases (Closed Front)
Many modern cases have tempered glass fronts. While beautiful, they kill Airflow if there aren't large side vents.
Tip: If you have a case like this and your PC is boiling, try removing the front panel during heavy gaming sessions. You'll see an immediate drop of 5ºC to 10ºC.
