Currently there's just the standard 120mm fan at the bottom in the front and the 120mm at the back. Now do any of you have any ideas on how to improve general airflow? Does anyone make something which slots in the CD bays? At the moment idle temps range from 43 to 44 and load temps runnining orthos get up to 58-59. I just want to sort if before summer comes and get the innards tidy. Also are exhaust fans worth it?
