I have an S Flex, it has decent noise:airflow but it lacks the xtreme touch. If you've got a fan controller or are willing to build a simple one check out http://www.nidec.com/fans.html# Try the 120mmx38mm fans if you have the space for them. I'm still using/have give away a bunch of their 92mm fans that I pulled off of some Pentium 2 systems about 6 years ago and they as strong as ever even after running 24/7 for at least 10 years.
Out of those, the S-Flex are the ones I'd go with. I've run a few of them in the past, and the dB:CFM ratio does seem pretty good. Might also look into the low speed Yate Loons, possibly even undervolted. Cheap price, good fans.
Most fans will make roughly the same noise at the same RPM. The new Slipstreams have very good airflow, meaning (when using a fan controller) they will give the same CFM as other fans at lower RPM.
This has been tested in some reviews and it works. I currently have S-Flex's but if I had to buy new ones, I'd go for the Slipstream (personally I'd go for the 1200 RPM, more than enough CFM).

Slipstreams are NOT quiet @ 1900rpm - if you feed them direct power i've found they sping around 2200-2300rpm.
If you want low noise they are not what you want. Not saying they are 'loud', but not quiet/silent. I have a fan controller so i turn them from 2200rpm down to arond 1400rpm and then i cannot hear them at all.
Yeah i was also looking at those magma's but here on XS there isnt much to find about it.
How do they compete with the S-Flex 1600 RPM and the Gentle Typhoon 1450 RPM?
I personally find my 3 S-Flex F fans too loud.
I am interested in this too as I am looking to replace the "Stock" Lian-Li case fans (120mm) with either SCYTHE S-FLEX fans or whatever else you would recommend.
I already have a 6 channel fan controller Which my Lian-Li fans (6 120mm) are hooked up to.

I'd say Scythe S-Flex has a good price and grat db:cfm ratio. Buy a fancontroller and undervolt it, they blow enough air to make a difference with great silence!
Thanks for the suggestions Bun-Bun and Smartidiot89
I already have a 6 channel fan controller (ZM-MFC1 Plus), so I guess it's the case of getting the Scythes' plugging them and and then dialing in to the sweetspot (fastest speed with no noise).
The Lian-Li A70B case fans are ok, but even at 7Vish they can be rather vocal. (I don't think they shift that much air either at this speed either).
Right so 1850rpm Gentle Typhoon or what variant S-Flex would you guys suggest?
What about these noiseblocker multiframe fans, have you heard much about those? (they are rather expensive, but have got some good reviews).
Best Wishes for the Festive Season

Thanks for the suggestion dctokyo
Are these the same Enermax Magma fans? (for some reason they are called twister here).
They are a bit cheaper than the Scythe Gentle Typhoon 1850 rpm fans. and half the price as the S-Flex fans.
I have not found many reviews of the Magma
Some say that they are very good, yet loud at 7V+ others say they are silent and push a lot of Air.
Do you have any Magma's?
Thanks, I will order either later today or sometime tomorrow
John
Go with the Slip Stream if you have a fan controller. At lower voltage they move a LOT of air, and very minimal noise. Otherwise one of the mid-range S-Flex fans like the 1600RPM ones. Not silent, but also very little bearing noise from them, just the sound of air moving
Ok guys I am in a bit of a pickle here.
The Enermax has had mixed reviews, some places love it, others give the Magma 6/10
Gentle Typhoons are loved pretty much by most enthusiasts around the net.
The slipstreams are good fans, but sleeved. Has anyone here got any experience with SlipStreams?
As for pricing the Enermax here is ~£8, the Gentle Typhoon ~£10 and the Slipstream ~£9
(S-Flex's being £14 so sort of pricing themselves out of the competition)
