Is a single 5" radiator enough for this?

I probably shouldn't have gotten this far without asking this question, but I can probably use it for a single-CPU system if this doesn't work out.
First of all, this is my first watercooling project, though I feel quite comfortable doing it.
I'm running a dual Celeron 366 system on the awesome and famous Abit BP6 with the magically perfect O/C speed of 100Mhz FSB (550Mhz). Low-performance means that this isn't my primary system, so I consider it my "conversation piece" at LAN parties. Therefore it's gonna be watercooled regardless of weather it needs it or not
I already modded my case by cutting & cramming in some of what's gonna be inside:
1u slim rackmount 300w PSU (done, looks sweet and leaves plenty of room)
Water tank and pump (sorta done, I wanna power it off the same cable as the PSU)
Radiator and 120mm fan (Done, blowing up as if it's a blow-hole)
Modified PSU shell for holding above components (Half-done)
I haven't even bought the waterblocks yet, but I can already tell that the small 5" radiator doesn't seem to have much more surface-to-air area than the combined 2 GW-FOP32-1's + ASII I have in there right now. Because there will be no peltier involved (Just using water for quick removal of the heat, not supercooling), I'm really only worried about actually loosing cooling performance over aircooling.

Is it likely that I will have lower cooling performance from watercooling this setup than aircooling it?

Remember, it is a .21m dual-CPU system with a large overclock and no peltier with a micro-sized 5" square radiator.

You're likely to retain the same amount of stability as you did before. However, I'm interested in a couple of things:

1. The CPU waterblocks are set in parallel. Right?
2. Is it a sealed water reservoir?

No waterblocks yet. Not planning on putting them in parallel because of the technical difficulties of making the water pressure to both CPUs equal (Water, like electricity will take the path of least resistance so one will be sitting in some-what "stale" water). Short of getting 2 pumps, I don't quite know how else to go about doing that anyway (A simple "Y" splitter will produce the "path of least resistance" issue). I will be running them in serial unless someone suggest that there's something wrong with that (warmed water from one CPU will hopefully be cool enough for the other). It seems to be how most BP6 users are doing it, even though I don't think they're using such a small radiator

That's what I was afraid of. That may not be the best idea.

There's something you might be able to do, but does this need to be a noisefree environment? The method I'm thinking of will create a lot of noise, unless you want to put the device farther away, but you'll need a stronger pump and more tubing.

^ Never mind - I just saw that you needed to be able to lug it to LAN parties.
