what's your feel on this fan? Is it really 37dB or is it louder?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...
You need to buy a fan controller. You can get a Sunbeam Rheobus for around $20, and problem solved. Just connect all your fans to it.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:
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.
That still seems like an awful lot of air movement - have you tried moving less air to see how much difference it makes? You may have hit the point of diminishing returns somewhere along the line. I guess it's all what you are comfortable with, but 50 dB has got to be pretty loud.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.
As opposed to inaudible noise?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
QFTYou 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.
Yep, I had the same with my front intake of my case since the HDD drive bay sits right in front of it. My Scythe S-Flex didn't push enough air for my taste. Replaced it with a SilenX I had floating around and I get much more air past the drive bay.QFT
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.
Panaflos ahhh yes L1A or L1BX so reliable and nice quality. No bling and I don't mind the noise they make at full speed, its a rather suthing air whooshing sound. Bot quite as much CFM as the OP is looking for though. Someone told me no need for 38mm thick fans and to try yates, but the yates don't have the same sound. They are maybe a little quieter but the sound of the fan not the air it is pushing. And they don't seem to have enough static pressure for me and they certainly won't be as reliable either. I think I will eventualy replace them with L1BX's....Except where this is not possible (HD bay)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.
