Removing the A4000 power supply fan?

[NorthWay]

a) Do you need to solder to change the fan in an A4000D?
b) Is there a list of fan size and airflow for A1000/A3000/A4000D?

The noise of my 4000 is beginning to annoy me. (Nothing compared to my old 2000 though. Even after a cheap resistor mod it sounded like it was preparing for take-off.)

Would there be space to snake back in something like one of these? http://www.ebay.com/itm/122103383578

Well, I have a https://www.quietpc.com/nf-a8-flx incoming so I'm looking for the best and/or easiest ways to swap out the old. The current fan is so much noisier than this pc it's not funny. (Which is _nothing_ compared to what my 2000 was like - even after having a "NoiseKiller" heatbased resistor that made it a lot more silent...)

I ended up just cutting the wires to the old fan near the pcb and squeeze the cable together with the other cables coming out of the PSU, and using a supplied 3-pin to molex converter to power it.

That was much smoother and less painfull than expected!
