Fan model The fan model can indicate how much fan noise the machine will generate when the temperature raises and fans begin to rev-up. The easiest way to find the fan model is to look through the ventilation holes on the back of the machine, or if possible, open the machine up and remove the fan from the case. The delta and Sunon fans are known to generate noise, while the Nidec fans are somewhat quieter. * Delta - Black and white/silver label * Sunons - Green and white label * Nidec - All back label The quietest fans are aftermarket Talismoon whisper fans.
