Scythe Shuriken on a 3pins motherboard ?

[paradigm]

Hello.

I Just bought a nice Shuriken.

this one got a 4 pins power connector .
My motherboard has a 3 Pins fan power connector.

how do i connect the 4 pins fans on my 3 pin motherboard ?
if possible whats the limitation vs a 4-4 pins link ? //


thx

ps: really nice ventirad and lightweight :-)

Just put the 4pin cable on the 3pin socket on your board. It will fit. False installation is nearly impossible due to mechanical layout of the plug. One pin of the cable/plug won't be connected. This pin would be used for PWM operation of the fan (= controlling the fan speed via the mainboard; automatic fan speed regulation based on temps).

thx u for your fast answer.

And than the cooler runs with 100% ? Or works the voltage regulation by the mobo?

[Oli]

No the regulation doesn't work - at least on Asus. I think there could be some boards which can also realize speed regulation on a 3-pin connector but the Asus feature "qfan" has never been working with 3-pin fans on my Asus boards. Although there are different reports concerning this matter in a German support thread for Asus P5K.

For PWM type regulation the fourth pin is necessary. I am using Zalman Fanmate 2 for regulation purposes but Scythe is offering a new fan controller if you want to do it from outside of the case.

The voltage regulation of my mobo work with the current coolerfan, its a Gigabyte k8nmf.
The question is, is it possibel to control the fan of the Shuriken by voltage regulation? Btw, when it works with the Fanmate it must also work by the mobo

Thats a good question for the guys on the Cebit i visit today
Thx

Practically every fan I know can be controlled by voltage regulation. Less voltage means less rpm. The only difference is how much voltage the fan needs to start up at all.

If your mainboard doesn't allow small steps to setup the voltage it is possible that the board doesn't deliver enough start up voltage. You should test it but chances are quite good.

I got 3 slip stream fans and another 2 S-Flex here and they are all doing well with voltage regulation. The Shuriken fan will pe perfectly controlable by voltage, too.

Surprisingly you don't have a 4-pin PWM connector. The fan can be controlled by voltage, but it is made for PWM, which should be better for it. Nevertheless it should work fine.

Rest was explained in detail, nothing to add from my side.

This would also hold true, if I have a setup with the MSI K8N Neo2 Platinum motherboard ?

See also my other question in this thread here:
My question @ Motherboard Compatibility List Thread

I desperately need a cooler that fits on that setup, as otherwise I cannot build it or get it started without a CPU cooler that is...

Hi! another 3pin cpu fan motherboard type here. Mine has a small other issue. It's a socket 939 Abit AX8(version 2).

It has just the 3pin cpu fan socket but also right next to that socket is an upright transitor/capacitor.

The fourth blue wired pin on the Shuriken has no space to enable the 4 pins to fit on this motherboards 3 pin Cpu fan socket!

So you use the blue wire connection pin on the shuriken for PWM control, as you said above, and it is not vital for the working of the shuriken to need that plugged in?

So a few questions i would need answered that might help others also:

1. What speed will the shuriken default to if the blue wired PWM pin is not connected?

2. If it's possible to run this 4-pin Shuriken on just the 3 pins(Black/Red/Yellow), can i cut/remove the Shurikens cpu fan connection casing for the blue fourth pin to make it fit my motherboard?

Thank you for your help. Zak.

Edit: Just for information, the stock Athlon64 cpu fan connection, which is 3pin(Black/Red/Blue), also did PWN on just those 3pins.

Edit2: I've had a look around some other cpu fan sites and often the pin connection type is mentioned in the product sheet(3 pin/4 pin etc). Maybe you could do that also - to avoid any confusion?

I've ordered a zalmann CNPS800 as that is 3pin(with PWM), and also low noise/low profile, but will keep my Shuriken for when i get a new motherboard that has 4pin - i really like the look/reports of the shuriken, shame about the pin connection incompatability.
