Is 37 DB Considered Loud for Sythe Kaze Jyuni 110 CFM @1900 RPM
I'd say 37db is pretty high for a quiet fan - definitely noticeable. Do you really need 110cfm?

Is 37 DB Considered Loud for Sythe Kaze Jyuni 110 CFM @1900 RPM
I went for the SY1225SL12SH (1900RPM,110CFM, 37dBA) only because I wanted to reduce the number of fans in my PC. I had up to 7 case fans at one stage (not inc CPU, NB or GPU) and went to this one + std PSU only as exhaust . In my opinion, I think I reduced overall noise and definitely improved temps.
This provides enough airflow to cool down even the Sun's Core...
I already have a Nexus fan:

the nexus c/w a 3 pin motherboard connector. I can't get that on my mother board, as my MB (it's a HP) only support a very small 4 pin. so in the end, I use the regular dongle (the regular size 4 pin connector--the same size that fits in your hard drive).
But the Nexus is only 18dB, so no biggie. But if I buy the following:
http://www.scythe-usa.com/product/acc/026/sy1225sl_detail.html
it's at 37dB when the RPM moves to 1900 rpm. So my question is:
1) is the Scythe variable speed? If so, is there a way to use that 4 pin HP motherboard connector somehow? As the MB controls variable speed. So even my rear fan is max at 50dB, right now, it's probably at min. speed, around 25 dB or so.
My rear fan is at max: 129.957 CFM, 50 dB, 3600 rpm NMB-MAT
So at max. speed, anything less than the above will do. Now as you know, the front fan should match the CFM w/ the rear, so 110CFM is somewhat doable.
I didn't design the machine, it's a HP XW9300 professional workstation. Those HP engineer design that fan to c/w this machine. I only hear 50 dB noise when I play games. The speed of the fan varies, for normal business use, it only makes audible noise
You guys need to learn a bit about static pressure as well. Some of these fans rated at high CFM may not be able to push jack shit through a heat sync.

I got my scythe slipstreams, and I'm not impressed at all. They have pretty much no pressure at all. I had to pull off the one I put on my TRUE, and put my Panaflo back on, because it wasn't moving any air through the HS. The one I put as an intake for the case moves pretty much no air either, since it butts up to an air filter. Looks like I'll stick to undervolting my panaflo's.
Deltas are stupid loud. It's strange, they almost seem proud of the fact.
I much prefer Panaflos to Nexus, Scythe, Noctua, etc. They aren't quiet at full speed (even the low speed ones) but you can turn them down to quiet and they still move a great deal of air. I guess it's the same theory a previous poster used with Silverstone fans -- you know that if there's ever a reason you can crank those things up in a big way.
