Best replacement fan for PSU?

Hi all, have a PSU which has now become my noisiest component due to water cooling the rest.

It's an EVGA 600B and the system only draws ~350W under full stress test on a hot day. I figured I will just replace the fan as I have plenty of 120mm spares lying around and I know my way around a PCB.

What are the considerations? Static pressure? Airflow? Low start voltage? I was planning to compare the existing fan with my spares and find something quieter but which 'feels' like the same airflow at a given voltage.

Any suggestions?

I would be more concerned about opening a device that stores a lot of electricity in its capacitor even when it is turned off. The rule of thumb with power supplies is to not even consider opening one up.

I suggest you get a power supply that is a known "quiet" PSU. Safer and surely not that expensive, and you can then just sell your existing supply to mitigate the outlay.
