Another useful How To, allows you to power all your rad fans from one fan controller dial (etc etc)

This is how I do it:

And this is how it looks in real life:

I'll ask here.

Talking to Spoon about daisy chaining without a soldering iron, and he said something about pass through molex connectors.

Where can I get one(is that all I need?) of these.

PS. I have 3 Xilence fans on my rad to power.
Oooooh

Urm, quite a few fans come with them.. all it is is a molex with a female and a male connector.

I don't have a soldering iron though...

What's stopping me pulling the molex pins from one fan out, and sticking them inside another molex output for a different fan?

That should work right?
Oooooh

Yes , link black and reds together - These are the power lines.

The Yellow in the sensor/speed control - You only want 1 conected to the header.

You should be able to splice them together with a soldering iron , and it will look neat and tidy.

Found this one on the net, pretty much the same what Marcus wrote. Maybe will be easier for someone to understand.

I'm not all too good with electronics, but this is something I thought about when I read this thread.

The yellow wire; what does it do? - I thought it controlled the fan speed?

If you're cutting the yellow wires to the other fans, are you not just controlling the one fan?

meh, tell me if i'm wrong :)

yes the yellow controls fan speed, and if you join them there will only go at the same speed :D

surely you'd want to control all 3? - Using the one cable?

Hi.

The yellow wire is the sensor wire for monitoring the RPM of each fan & doesn't control the fan speed. The fan uses this wire to send a signal to the mobo's fan header, where the bios or OS will adjust the voltage supplied to the fan based upon this RPM reading.

It isn't a good idea to link sensor wires together, as this will give the motherboard a false RPM reading. :)

If you connect the fans like that, it doesn't affect the speed of them does it? just uses up more power right?

Doesn't affect speed at all. they all get the same power so they all spin at the same speed.
