Default Radiator--Push or Pull

I'm starting to build my two water loops. I've got two external radiators that I'm mounting outside the computer. The easiest way for me to make it work is to use the fans in pull mode; push would require serious logistical tweaking.

Is there any reason not to use pull?

This review might be helpful : Radiator Fan Orientation and TFC Shroud Testing & Review. Seems that fast fans work better when pushing and slow fans work better pulling.

Doesn't make a huge difference either way really.

Which radiators and fans are your using?

AeroCool 120mm Turbine 2000 Fan

On a related note, since there will be three fans tied to the CPU/NB-SB, and three fans tied to the dual GPUs, what is the best way to route the fans from the motherboard? Should one set be plugged into the CPU fan jack? This way, I could have their speed linked to the CPU temp. Is there anything like this that would work for the GPUs? There is a jack that was tied to the fan on each card before I removed the old air cooler; I'm thinking that might work, but it would only be able to get the results from one card; if there is no support for Crossfire in a game, it defaults to the first card, correct? Or should they just run 100% all the time?

Also, is there any kind of three-way splitter I can use for the fan cords?

EDIT--One more thing... I got black tubing, because I think it looks cool. How am I supposed to tell if there are any bubbles in the lines? Should I just get clear tubing?

If I recall those fans have pretty good static pressure so I would run them in a pushing configuration.

Yes you can find them, or you can just splice all the fans together with a little bit of soldering and DIY-ness

I've ran black tubing for a couple years now, if you use a T-line you can listen and should be able to hear if you have any bubbles still in the line as they work themselves out. If you have a reservoir, you don't really even need to worry about bleeding.
