Should AIO Fans at the Top Be Set as Exhaust or Intake?

I'm not sure about the airflow direction for my AIO fans that I just installed at the top of my case. I based the installation on the logos on the fans, thinking they were for intake, but I believe they're configured for exhaust. What's the best practice here?

Generally, fans at the top should be set to exhaust. This helps remove hot air that rises, keeping your system cooler.

It really depends on your overall fan setup. If your top fans are exhausting, you might achieve positive pressure, which is good for reducing dust. But if you have more intake fans, like at the front, it can create negative pressure.

Yes, the general rule is to exhaust from the top and back. This prevents any heat build-up and keeps your CPU cooler, especially if you have an AIO cooler. Just make sure your front fans are still pulling in enough air!

Most setups have the top and rear fans as exhaust and the front as intake. Just check the arrows on your fans; they usually indicate airflow direction. Some people prefer to show the 'pretty side' of the fan with the logo, which can affect orientation.

I've got mine set as exhaust for the top and back, while my front fans are intake. It's the standard setup and usually works well for most cases.
