So right now I have 2 Corsair SP120s and I was wondering how I should best install them. I'm 100% sure i'm going to use one of them to replace the stock fan in my Cooler Master K350 which is right behind the hard drive cage but I was wondering if it would be ok to use the other one as an exhaust even if there would be little restriction since I keep the back of the tower around 3-4 inches away from the wall and i'm using an AIO liquid cooler so there's no big CPU fan blocking the way. I could also use it as a side exhaust which is directly against my GPU. Was wondering if using a high static pressure fan without any restriction to airflow would be ok.
