Hello,
I'm wondering if i should go for an extra case fan on the top, But i'm not sure if i should go for 140mm 2x or 120mm 3x, or just 1 1200/140mm because of the positive / negative airflow.
The case I use is: Corsair Obsidian 450D mid tower. Right now there is 1x 120mm fan in the back of the case and 2x 140mm fans in the front.
So is it worth going for 2x 140mm, 3x 120mm or just 1 120/140mm fan because i'm afraid there will be negative airflow in the case if i max out on the fans and don't think that's good either?
Not sure if i need to name out the rest of the specs of my PC but I will list them down here in just in case^^.
