Replacement power supply fan

[Fred Forsythe]

Built a multimedia machine about 2 years ago, using a Cool Master 600 watt PS, the fan in which is beginning to fail (sound/speed goes up & down, even when run on a bench power supply, turning by hand feels rough, etc.), So I'm looking at Newegg for a replacement 120 x 120 x 25mm fan. Cheap enough, but I don't want to get too much airflow, for noise if nothing else. CFM ratings range from about 20 to about 120. What would be an appropriate CFM rating for a replacement PS fan? These are case fans, which means I'm going to have to solder on the existing internal PS connector, so I suppose I could stick a resistor in series to lower the speed a tad...

TIA

A high airflow isn't necessarily a problem...look for the fan with the lowest noise rating. I've seen some fairly high flow rate fans with pretty low noise numbers. As high a flow rate as possible is always a good idea.

Something like this Thermaltake...

Thanks for the suggestion MJC, looks like a good one.
