Now about the fans. NCIX might sponsor me on the fans, so I'm narrowing down to these.
Thanks guys, lots of great recommendations, but I've been narrowing it down to these. Any thoughts between these?
Yate Loon D12SL12s
at 12V and 7V (47CFM + one setting lower)
Noctua NF P12-1300 at 12V and 7V
(54CFM + one setting lower)
Yate Loon D12SH12s at 12V
Scythe S-Flex SFF21F at 12V
Scythe Ultra Kaze at 12V
Panaflo H1s at 12V
I'm thinking the low speeds plus one undervolt for the silence guys, then the mediums and high speeds at 12V should cover the range pretty well?
Mixing two many apples and oranges!!!
Every fan has a pressure/flow curve like any other pump. This is equivalent of testing a water block with different pumps rather than varying the flow and measuring the pressure.
I would take U1s, mount a large number (8 or 10) to create a chamber. Just a rectangular openning which could then be blocked and the radiator clamped to it.
A similar box could be clamped to the inlet of the radiator, drawing through a channel with a simple flow meter. Then you would have the flow and the pressures on either side of the radiator. You could vary the pressures and flows by changing voltages and turning off and blocking fans.
You could just use a single AC vacuum pump rather than the fans.
You could use a reference set of restriction plates infront of a shoud to independently test radiators with the same flow/pressure measurement setup
Quick, simple, flexible, and revealing tuning possiblities rather than the performance of fans.
