I am moving my computer into a new old stock (NOS) Corsair Spec 2 case. It has two big fans in the front. One of them is down in front of the box where my 3 1/2" hard drives are installed. Is it worthwhile to connect that fan, or will the air blockage negate it's value? The upper front fan is clear of obstructions, as is the rear fan, and I am installing 2 exhaust fans on the top. The side won't be able to be used for a fan. Clear plexiglass. I don't have new system, but it's good enough for photo editng and RPG mmo gaming. I appreciate all help.
