I've got an XFX Pro 750W PSU currently and it works fine, bought it second hand, no problems there came in great condition and not noticeably dirty in anyway.

But the fan noise! It's noisy. Not a rattle, or a bad bearing, just general noisy fan+airflow noise. It's in a spacious case, with a split design so it is in its own chamber and not taking in hot air from a CPU/GPU either.

I'd like to replace the fan, I've done it before +am aware of the precautions etc. I don't think it's on a any rubber mounts so will do that at the same time too.

Just wondering what a good replacement fan would be, CFM/dB wise?

Need to check if its 120/140mm too.
 
Cool, at the same tie might get rid of the 92MM on my CPU cooler and bodge on a 120MM also, can get double the airflow for the same dBs.
Will overlap over the chipset/RAM cooling that way also.

If required will a 4pin fan work with just 2 pins connected? or do I need to wire the PWM wire into the +ve (this will trick it into just working at max rpm)
Or is it better to daisy chain it from the CPU header and have it under full pwm control? As the PSU load will scale with CPU temp/load in theory?
 
I'll go ask on another forum :)
from my PWM experience you need to get a high signal on the PWM wire, not sure though.

I'm not too worried about pin headers as in most PSUs s I've looked in the fan is soldered so no header anyway.
