I normally run pos pressure to avoid dust bunnys. My theoretical reason is increased pressure normally means higher density so higher density air means better cooling.

Actually, you don't have to make taps: you can simply buy pipe-to-thread adapters: even Lowe's carries that! Then you can screw in your polypropylene barb.
Positive pressure makes sense that way, but the problem is that it couldn't possibly be significant to actually make a measurable difference. I don't think that a denser gas (CO2) would even make a measurable difference, but then I've never tried it (someone else?)
