Bought this system just over a year ago and have not had any issue's with it besides this little nit pick. While it's hooked up to a 17" ADC display that came with the system the fans rev up and down depending on the CPU load and are generally quite quiet. Unfortunately when I hook the system up to my 20" first revision DVI apple cinema display the fans are at 100% no matter whats going on. I would like the fans to behave with the 20" they way they do with the 17" ADC display, anyone know if this is possible? Complete system spec's are in sig, I also have USB card in it and an SCSI card.
