(possibly should be posted in General/Overclocking & Cooling) 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?
