Kaze Jyuni 1900RPM Slip Stream 120mm Fan

The Slipstream 120mm Case Fans have been developed solely by Scythe engineers. They found out that by reducing the dimension of the centre hub and the wider surface area of the fan blade increased the airflow. There are a range of different fan speeds to choose from which meets the demand from a wide variety of users in the market. Silent users to power users now have more choice when it comes to choosing a suitable case fan.

- Air volume at full speed (12V), CFM ±10% 110.3
- Noise level at full speed (12V), dB(A) 37.0
- Fan speed at full speed (12V), RPM ±10% 1900
- MTBF 3.5 years

I have 3 of these on a 360 rad cooling my cpu nb and sb i7 2.6@ 4.2 highest temp so far has been 53 on full load. they're great 2.5 years none stop use on 100% speed and 1 of them has just given up. pretty amazing really. ill be getting the same again to replace!

Awesome Fans.

These are brilliant value for money. Bought two of these to replace the standard fans on my case and they dropped the temp from 37c to 33c on idle.

Iv got a AMD B55 X4 3.2 oc'd to 3.8 and on Prime95 i never see over 50c.

I dont have a fan contoller yet so they are constantly going full chat and are loud. I only use this machine for gaming so its not to bad when iv got the headset on.

You can feel the fan sucking your hand into it!
i just use one of these as an exhaust, along with 2 silent fractal 120 intakes and the machine is virtually silent, even at full speed you can only hear the air rushing through he blades (maybe i need to remove the mesh on the case)

motherboard reports the speed at just over 200 Rpm. oh, and the cable is anything but long.

I use mine as a pull-fan for the OcUK equivalent of the Corsair H60 and i use speedfan to control its speed. At full whack it runs at 2009 RPM and is pretty loud! I wouldn't want this running at full whack when doing anything other than gaming. My CPU temp (Q6600 @ 3.4ghz) maxes out at 60C, so has knocked more than 10C off my previous fan, which was only capable of 1400~ rpm. On the flip side of the coin the fan is silent @ 1000rpm and has taken about 3/4C off the idling temps and sits at 43C. Overall am very happy!

Good fans, but a touch on the noisy side

Well, they certainly push the air well don't they? According to the motherboard's RPM readout, these are actually more in the region of 2100rpm. Excellent radiator fans.

They are intolerably loud if you are just web browsing or whatever, though when gaming are great (I wear headphones, thankfully). I'd suggest undervolting to ~5V, at which point they are essentially silent.

I would recommend these, assuming you have a fan controller, or are willing to rig up a molex to a switch that controls the voltage (a DPDT On-on switch, with the 5V and 12V lines from the PSU as alternative inputs). Or if noise really is not an issue...

Hugely noise at full speed even when suspended from thumb and forefinger. Have not tried with resistor but image it would be much More quiet. Airflow is astonishing. More powerful than some desk fans twice the diameter! Contrary to what I've read in various places the static pressure appears to be very good; at least when set to pull. Temperatures dropped massively when added to a H50 in pull. Can get a C0/C1 i7 to 4GHz with this fan. Your concentration during tense CSS mixes is definitely going to take a knock though. Loud as fudge.

Well i was expecting load but they quite quiot . Just replaced my titan fan on my cooler with 2 of these in push pull. Temps droped 3degrees in prime

Im using two of these on my Megahelems to keep my i7 920 @ 3.8GHz happy under 60C at all times. geniunly very good fans.

They are noisy, but nowhere near as loud as I was lead to believe. Coupled with a fan controller they are ideal.

Ben 2009-12-15

Excellent fan

Got one of these paired with a i7 920, Cogage TRUE spirit CPU cooler, MX-3 and a HAF 932. This cooler makes the i7 at stock idle at 30c and peak at 49c after 30 min of Prime 95.
It's quite loud at full speed but runs wisper quiet at 1200 rpm. Great static pressure also.

Great Fan

Bought one of these to mount on the side panel of my Antec 900.I use it as an intake fan and the temps of my GPU dropped from 58-60*idle to 50*idle and the CPU went down from 22* idle to 19*.

Put a fan guard on because these things

Thomas Tunney 2009-09-23

best fans ever

If you want fast, high airflow fans then look no further. These babies pump out a whooping 110.31CFM and they only spin at 1900rpm. The Sycthe Ultra Kaze which spins at 2000rpm and is thicker than these fans only pushes out 87CFM! I think it must be the way the fins are designed, I attached this to my Thermalright Ultra 120 Extreme cooling a Core i7 920 @ 4.0GHz and temps now ever exceed 68*C full load!!! Down from 78*C thats 10*C from just changing the fan!!

Thank you Scythe now I will never ever buy any other fans but yours!
