I have two fans in my case. One in back up high exausting and one on the floor of the case bringing in air, which I think is a bad spot to put a fan, but thats what I got. The power supply (thermaltake 420 watt ) which has two fans. I was thinking about putting another fan on the side panel as a additional intake. Will this disrup the airflow I have or will it help. Case temps are ok but just would like to see better temps. If a fan on the side is a good idea where is the best place to mount it. Low or over a particular spot ie. vid card, cpu. Thanks for the help in advance.
