Fan Controller & Radiator Fans

Just realized I accidentally posted this in Water Cooling section.. don't think that is as appropriate as here...

Basically what I'm looking to do is replace all the fans on my wc radiators.

Noise isn't a HUGE issue to me (within reason, but I don't need silent), but regardless, I was thinking of getting SY1225SL12SH (4 per radiator, push-pull setups) and a fan controller for them. I'm not too familiar with fan controllers, and since I can't really find any in stores locally to check them out in my hand in person I'm going to need some advice, please.

I figure if I am using a controller, I want to get fans that are powerful, if even a bit noisy, because I can always dial them down for normal use and then, using the controller, step them up if I am benchmarking or doing something very intensive.

I have 2 x 120.2 radiators in the case, and I'm thinking of doing a push-pull on both of them. Any advice is greatly appreciated, thanks!

I like the price of those, that is for sure

In comparison to the Scythe's I posted though, the Yate Loon's are 88cfm @ 40db vs Scythe 110cfm @ 37db

Are those numbers accurate, or misleading as it seems a lot of manufacturers do. Anyone with any experience with either fan - or something else?

Thanks for the information though

im running 3 yate loon high speed fans on my rads with a fan controller, when just playing games or just on the net i keep them all the way down and when i bench i crank them up and they do put off some noise but its not to bad for the price

Stop just looking at CFM.

1a) When first testing this fan for the Fan Filter Comparison I did, I noticed it was actually performing okay on the radiator. Airflow numbers weren't horrendous like I anticipated. The 1900RPM "SH" actually had similar airflow loss to the 1900RPM S-Flex G. I was kinda flabbergasted. Then I turned off the music, turned off the A/C, turned off the TV, turned off the loud-as-sin Xbox 360, turned off the dogs and turned off the gf and I noticed something--the Slip Streams were getting significantly louder on a radiator. Well beyond the point of turbulence noise...it was like the fan was increasing its RPM...significantly. Now I haven't tested THAT (RPM sensors I've learned to not trust, thanks ASUS, Intel, Abit, and DFI), but I figured I might as well test the noise it makes on a radiator...then I realized if I was going to be testing the noise it made on a radiator, I'd have to test all fans on a radiator for noise. No longer could I assume the difference would be negligible....thanks Scythe.

What about static pressures & 120mm x 38mm as opposed to 20mm for radiator testing?

I'm also not quite sure what that chart necessarily represents? I see the link/chart is comparing a bunch of 50cfm rated fans - and then actual results.
