2 general rad cases; higher airflow resistance (2 core) and lower (single core)
- 2 core selected for performance, more powerful fan
- single core for lower noise, less powerful fan

is either rad configuration 'better' than the other ? (to establish an air flow reference)
seems that the air flow pressure range would be greater with the 2 core/more powerful fan combo
2 rad cases fine

I assume fans are 120mm X 25MM?

When I do fan comparisons on homologous fans I like test them @ equal RPM vs. Volts. method, if there are diff. in performance it is quickly apparent.

been hung up waiting for a 4"WC dP unit, which is now being caled
added a pitot tube to each fan as in the images, be interesting to see the correlation

the Nexus is 120x25, the Panaflo is a 38, is this a problem ?

trying to figure out what single core rad to use (it will not be Swiftech's)

suggest 6 V also -> limit for a good number of fans (AFAIK), so four point, instead of three.
(yes, admittedly three will be very close 7/6/5 , but isn't that the point?)

the Nexus is ok at 6V, the Panaflo FBA12G12M does fine at 5V (below spec)
