Hey,
I've got an Antec NSK4400 case which is great apart from the fact that you can only put an 80mm fan in the front.
I've currently got a Sharkoon 2000 80mm fan in the front and a 120mm TriCool in the back, but the 80mm fan is a bit loud for my liking.
I know I could just lower the speed but I want to keep the temps/airflow in the case.
Just wanted to know if it would be of any use putting a 120mm fan in the front using an adapter like this one: Maplin > 80 to 120mm UV Reactive Plastic Fan Adapter
Not too sure about it myself as the hole is still gonna be 80mm.
The other option is to cut a bigger hole
