I had an Antec EA430 before replacing it with a linearly powered Pico. In the cMP^2 scenario, it is perfectly safe to run the PSU "fanless" (simply unplug the fan) as long as you're not concerned about voiding the warranty. My old configuration (G31M-S2L+E7200+EA430) could run 24/7 for weeks with no stability or heat issues.

Are you using two Picos for the motherboard and P4?
I haven't tried a Pico yet.
I just removed the fan from the spare PSU, no problemo.
How did you get the physical P4 connector working with the linear 12v, cannibalize another ATX PSU?
I just disconnected the fan from my Corsair HX620, and it's a VERY nice improvement. Noticeably more ambiance, nice increase in bass extension. I'm back to going USB to the DAC with the Wireworld cable - that seems to sound most right to me.
When I went with a separate P4 a few days ago, I noticed horns sounding much more like horns. Before that they were recessed, with no bite.
Next step is a linear 12v for P4.
Love these cheap power tweaks!
All you do is cut off one end to directly solder to your linear supply and the ther into your p4 slot on the mobo.
What theob said. I recommend rewiring the P4 with higher quality cables though. The improvement over "stock" wires is quite noticeable.

Only one Pico, I use a plain 12v linear for the P4. Pico + 12v, while not a complete linear setup, is still a significant setup from the Antec EA430. Well worth the investment imo.
