Hello,

I have an OCZ StealthXtream 400W PSU and I wish to replace the 140mm fan and I have narrowed it down to roughly the following choices as they all can shift air around 60 CFM:

1) Noctua NF-P14 FLX Vortex-Control 140mm
2) Be quiet! Silent Wings USC 140mm
3) Fractal Design 140mm Silent Series Cooling Fan (Only 39 CFM!)
4) Antec Truequiet 140mm (Only 32 CFM!)

The OCZ is an efficient wee PSU ranging from 82-85% efficiency and I got it for £30 new!

I am trying to fit the quietest fan available. I am not sure if the existing fan( yate Loon D14SM-12) is PWM controlled. I read somewhere Noctua fans do not like PWM control.

Note: There is only a 2-pin Black/Red power connector inside the PSU itself, I assume I convert the 3-pin connector to a 2-pin by removing the earth connection.
 
Nope its only 14 months old but I don't care.

I have always taken everything apart since I was a kid and love modifying stuff for the better :cool:

Brilliant tutorial Tealc! I have all the kit e.g. heat-shrink etc. already;)

Whilst working on my hi-fi amps I always admired the huge heat-sinks allowing passive cooling. It would be good to have one side of the PC tower a huge heat-sink allowing fanless cooling:D

Anyway I'm still not sure which fan to buy although I am aware Noctua are tantamount to Rolls Royce and you would be lucky to get 6 pints of beer for the cost of this so I think I'll get it!

Many thanks:D
