N5200 Hardware modifications
From Thecus Wiki
Power supply Fan
Beware that replacing this fan will void the warranty for the power supply.
The 40mm fan in the PSU is very noisy. Replacement fan
Papst 4121FM 40 * 40 * 10mm 19dB 6m3/hour airflow
Due to its thickness this fan is easy to install, but I needed 4 machine screws with nuts (16mm length) as the original screws dows not fit. After replacing the fan, the PSU unit is close to silent.
