Cooling X1900CF & X1950XT AIW: Series or parallel

[L33T]

Which is best, cooling them in series or in parallel using Y's?

Definitely series. Stay away from Y junctions.

Definitely series. Stay away from Y junctions.

Or L junctions or T junctions, unless its a T-Line, and all other junctions in general. Simplify.. not make more complicated :) Of course, the bay reservoir creates a 180 degree turn, but that's one exception :)
