Breaking into and analyzing an old Quanta switch

The first thing I noticed about this switch is that it is quite loud. Not unexpected for an old 1u rackmount switch.

Three AVC DV04028B12U fans pull air through the chassis. One provides straight flow, while two push air over the power supply.

I replaced these fans with Noctua A4x20 fans, which reduced chassis noise significantly.
