af or sp fan for exhaust

[Raggisuer]

Hello.

So i wanted to get a new fan because the stock front exhaust fan makes a lot of noise i'm using the case carbide spec 01 if that's useful to know.

There is a dust filter infront of it so my question was should i use a af or sp fan here?

I would assume you would want a AF fan, dust filters aren't too restrictive

In restrictive situations, in either side of the fan, it is best to use a static pressure optimized fan.
