I would like to ask where should I place my cooling fans to optimize airflow and reduce noise as possible. I'llbe using a corsair obsidian 550d as my case. How many fans should I use? What fan size should I use? What brand of fans are also good in cooling and being quiet? Should I also replace the rear cooling fan that comes with the 550d?
Sorry for the questions sinceit would be my first ever build. Answers would ne appreciated.
