How To: Daisy Chain Fans - Page 4 - WaterCooling UK Forums

yes basic electronics books are pretty usefull, with a bit of simple electronic theories can help modders alot.

OOOO takes me back to my early learning days.

tumble, would be interested to see what your circuit does and etc etc...

I dont make as many circuits and stuff anymore, coz i started buying stuff.

Audiometer was last real project. and before that, mate needed something quick for a presentation for his scouts i think it was, so built him an amplifier for his pc so all the kids could hear the presentation

.

In fact, might have it powdercoated as it was nice kit.

I have 4x Zalmans chained and hooked up to my Lian Li stock case controller

It handles my 2x quad chains and a dual chain

Miffed at to how this will work?
Can you give me an explanation?
Thanks!
Like: How does the 1 black cable, 1 red cable, 1 blue cable and the last Yellow cable fits in a 3 pin fan header?

The blue wire controls the speed at which the fan turns, if it is not connected then the fan will usually run as fast as it can. The yellow wire is used to signal the RPM of the fan back to what ever it is connected to. If you connect multiple yellow wires together then you get wierd RPM readings anything from 0 rpm to the max speed of all the fans added together.

Since some motherboards require to see an RPM signal on their fan headers in order not to raise alarms or automatically shut down the PC one fan yellow wire has to be connected.

Once you ignore the blue wire then you just have red, black (all bundled together) and a single yellow wire. This is the three wires that you connect to a 3-pin fan header. Thus four into three does go, sort of.

Fan speed in the scenario is controlled either by adjusting the voltage on the red wire or by pulse modulating it.

So I just cut off the blue wires?
Thanks

*cough*

unless its for a cpu fan then cut em off imo.

Capedkid · 18-02-10, 03:49 PM

Cpu Fan?
Do you mean Radiator fan?

Thought red and black were power to the fan, blue was reporting back current RPM, and yellow is the PWM pulses to control the speed.. ?

Edit: Ignore me, its as posted above, red + black = power, yellow is the current speed from the fan. Just my pump uses a blue wire to report RPM back....
