I am thinking about upgrading/ silencing cooling in my Lian-Li PC-65B. I have read that it uses 4 Adda 80mm Fans, which seem to be decent, but could be better.

I would like suggestions on what the best way to improve cooling while also keeping it quiet in the case. On the side panel there is a section in the corner with small holes for airflow (see picture). Would it be pointless to put a nice 120mm fan here (Scythe or Yate Loon)? I could also add an 80mm fan in the floppy drive bay, but this wouldn't be very quiet. OR I could upgrade all of the 80mms already in the case (maybe to Noctua's if I can afford it), but this might be harder.

Let me know what you think. Thanks.

80mm's wouldnt be really quiet imo. best to find a case with 120mm or bigger.. less rpm = quieter with same airflow

Its a real nice looking case so I wouldn't force you part with it.

80mm fans require a lot of rpm for decent cfm, therefore loud to perform, poor for silence. I'd say grab one of these 80-120 brackets for the exhaust and blowhole, leave the intake as they wont pull much when silent. These 120mm Slipstream fans should do for good cfm/dB or if not go find some 120mm fans at either 1200rpm or below.

I'm not sure if I can easily swap any of the 80s for 120s, except for maybe the back since my fronts are intake. It would be impossible to put a 120 for the blowhole without cutting out some aluminum or having 33% of the air blowing against the casing and not to the outside.
