I just installed two Coolermast 80 mm fans in my side window. They don't have any fan grill or filter on the outside though. Should I worry about dust and all that bullshit? or am I safe?
I'll do the same. BTW...I know you were using the Lian Li for awhile. The two case fans I got lowered it by around 10 degrees (give and take a couple under different conditions). It wasn't worth it cost wise, but I finally feel good about the case.
