Fan Static Pressure

[eduncan911]

Someone backup my theory:

0.209 inch-H2O > 1.781 mm-H2O (0.07 inch-H2O?)
0.209 inch-H2O > 0.305 mm-H2O (0.012 inch-H2O?)

I figure the values in () by converting mm into inch.

Basically, I'm comparing this fan:

To these fans:

You also might look at the 140 x 25 mm Yate Loon fans and see if either the D14SM-12 or D14SH-12 float your boat. They are much cheaper to buy than any of the others and PPCs has them in stock. The D14SH-12 looks to be a real beast at 140 cfm airflow and 48.5 dBA. But they have the rpm listed wrong at PPCs, as theyare shown being rated as 2800 rpm fans at the Yate Loon website.

Whats the static pressure (mm H2O) for the D14SH-12?

I looked on their website but they don't have it listed. But from past experience with 120 mm Yates, I would think it would have good static pressure. You can always email them and see if they will give you some static pressure numbers.

Thanks man! Yep, I was dead on with the simple conversion from mm to inch. It matched the charts in that link.

Wow, never found those before! Aiight, going to order those as that's just about what I was looking for. Those San Ace are just too expensive, and my system does just about fine with the existing 60 CFM fans. So, having 140 CFM should be a bit overkill.
