Scythe Kaze Jyuni 500RPM Slip Stream 120mm Fan

The Scythe Slip Stream 120mm fan - designed to increase performance without compromising noise levels.

Scythe have released some new 120mm case fans, the “Slipstream 120mm Case Fan”. Their main aim with the new fans was to increase performance without compromising noise levels. 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.

Customer Reviews

Perfect for HTPC

,

I am very happy with these fans. I have two installed in my HTPC and I can’t hear them. Obviously the air flow at 500rpm is little more than a draft but it seems to be enough in my system. Highly recommended if silence is your priority, but would suggest something more powerful for more extreme systems.

Dead Silent

,

Now I have a new problem! Is the dang thing running??? Finally found a dead silent fan at a very reasonable price. No need to isolate with rubber either.

Excellent silent fan

,

The airflow from this fan isn’t exactly a hurricane, but then at 500 rpm you wouldn’t expect it to be. It really is effectively silent; you have to put your ear right up against the grill to know it’s even turning. One warning though: if used with a Fanmate, it doesn’t reliably start-up on the minimum voltage setting.

Silent Fans

,

I have two of these as intakes on the front of my Antec 300 case. They are, as far as I can tell, completely silent. I haven’t undervolted them, but I have connected both of them to 1 4-pin molex via a 2-way 3-pin splitter.

I will be buying a few more of these to replace the noisy supplied case fans.

amazing fans

,

I’ve got two of these fans inside my Antec Fusion HTPC, replacing the noisy stock Antec triflow fans.

You cannot hear these, making the PC almost silent. I had a mate around the other day who simply didn’t believe the PC was even on. And temp wise they’re good. My HTPC is frequently around 40 degrees which is perfectly acceptable - even under load when playing lots of videos.

Get them!

FAQ

  • How do I measure fan size?

    The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.

    As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.

    If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.

    83mm between screw holes:92mm fan size
    105mm between screw holes:120mm fan size


  • I received a small cable (resistor) with my fan; what is it for?

    The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.

  • How can I tell which way the air blows through the fan?

    Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.

  • Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?

    Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.

    The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.

    Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.

“Great knowledge perfectly applied”

“Bought a quad pc sat tuner, I was not 100% sure what number of LNB inputs were needed asked the questions to the great chap who answered the query and even said if it did not work out right for me to send it back no quibbles asked and get a full refund. it works as said and doubly so following the responses given by quietpc”
