MO-RA

The MO-RA3 family of external radiators is a product of Germany's Watercool. It is available in 360mm and 420mm models. The former natively supports nine 120mm fans; the latter natively supports nine 140mm fans (18 on the Pro, which supports fans mounted on both front and back).

Wiring

An Arctic P-14 PWM PST RGB 140mm fan requires a maximum of 0.17A for the fan and 0.20A for the LEDs (all at 12V, so 2.04W and 2.4W respectively, 2.44W total). They provide daisy chaining:

P-14s	Fan watts	LED watts	Total
3	6.12	7.2	13.32
6	12.24	14.4	16.64
9	18.36	21.6	39.96
18	36.72	43.2	79.92

The Noctua NF-A14 is 0.13A (fan only), 1.56W. There is no daisy chaining.

NF-A14s	Fan watts
3	4.68
6	9.36
9	14.04
18	28.08

Pairing 9x P-14s on the front with 9x NF-A14s on the back yields a maximum 54W of 12V power draw, exactly 4.5A. Coincidentally, this is the exact amount of 12V power provided by the 3 1.5A 12V pins of a SATA power connector.
