Scythe Releases Kama Flow 2, New Fan Series with EX-FDB Bearings

[btarunr]

Japanese cooling specialist Scythe presents the new Kama Flow 2 fan series. Equipped with the newly developed silent EX-FDB bearing, these fans are available in three sizes (80mm, 92mm and 120mm) with three different rpm models each.

The EX-FDB (Extra Fluid Dynamic Bearing) comes with a group of "V" shaped grooves, ensuring an even distribution of the oil film in the shaft housing and thus reducing friction to a minimum level. In this way, low noise and a lifespan of 120,000 hours (MTBF) can be achieved. Especially the low-speed versions are suitable for use in silent computer systems. For easy connection to PC power supplies, a 3-pin to 4-pin Molex adapter is included.



Kama Flow 2 case fans are now available for a MSRP of 6,25 € / USD 11.50 (80 mm version), or 6,75 € / USD 13.50 (92 mm version) and 8,40 € / USD 14.80 (120 mm version). All prices excluding VAT / Tax.

There a bit expensive but scythe seems to be putitng out some really awesome fans in the last little while. Then again in a few months they should be lower in price

 

[RejZoR]

Expensive? Have you ever seen Noiseblockers? Now that's expensive. But they sure make really good fans.

i spent 5$ a pop for my 8 gelid silents. So yeah 10$ is a bit more expensive then I'd like to pay for a fan, especially when considering in the fact that the gelid army would be replaced.

the old kaze-juni series still seems to have the better specs (more airflow with less noise)
For example the 120mm
SY1225SL12M 1200rpm 24.00dBA 68.54CFM 0.26A

I would want to see that EX-FDB thing on slip stream series. Those have much better airflow...

 

[WarEagleAU]

I think I paid 14.99 for my Kaze Kyujin or whatever it was.

I don't remember what I paid for my slipstreams, but I think it was like 10-12 each. They were really nice though, but I killed one last week (my hair got caught in it and I was trying to pull it out with a pick, but slipped and screwed something up) and the other ones bearings starting to go.

I've got two Akasa Apache fans coming Wednesday - just under £13 each (!)

Apparently 6.9 dB @ 600 RPM to 16.05 dB @ 1300 with 57.53 CFM ...I shall see!

Fan Wars FTW!

If those specs are accurate, and I can find them for <$15/fan then I'm getting a couple too. The blade design actually does look rather unique, with the slight wave at the end. I'm curious how well it works. I'd really appreciate it if you made a new thread and did a mini-review when you get 'em. PM me if/when you do.

Also, I've got a great tip for anybody buying new fans that wants to test them out without the noise the rest of their PC:
A great way to test fans by themselves (ie: so you can turn off your pc and just listen to the one fan), if you've got a soldering iron and some spare connectors, is to wire a male 4-pin molex connector to a 12-volt wall-wart power supply that you might have lying around for various other devices. You can look at the label on it and make sure it has enough amperage. If you have such a power-supply and want to try it, but don't want to cut the end off, can't solder, don't have the right connector, or have any other concerns, PM me or leave a profile message and I'll show you how to safely make the connection with common household items.
