I've checked my Corsair 740 with 3x120 front fans at full speed and rear exhaust fan at "normal" in SmartFan. Was it correct? I wasn't overclocking, so I was curious if running the rear fan slower than the front case fans made sense. Also, the rear fan is linked to the CPU temperature sensor. Extra info: I'm using a dual-fan setup with a DH15 cooler on my 8700k. Thanks for your help!

Dust filters effectively prevent most dust from entering your case. I also use a tool to clear dust from lenses, which is useful for electronics too. It performs well without problems with moisture or static electricity.

You likely don't require fans spinning at maximum speed. Consider employing PWM fans along with your motherboard's 4-pin fan headers. This allows precise control of fan speeds, helping to manage heat effectively while reducing noise.

However, for your situation, positive pressure is the better option. Removing air from the case (negative case pressure) is less effective. It also gives you more control over how the cooling air moves inside. Negative case pressure draws air in through the easiest route.

Well then the answer is straightforward. You require a greater number of fans drawing in air than expelling it.
