Never set a fan up, need help.

Hello, after reading this, https://www.rollitup.org/do-yourself/8402-how-turn-pc-fan-into-2.html

I needed some more help, i have found an example fan, http://cgi.ebay.co.uk/120mm-12cm-PC...atsinks_SR&hash=item483b4f83eb#ht_2839wt_1033

I would then use a phone charger, strip the wire down, leaving me with a black and red wire? How would i then connect this to the two wires from the fan? Electrical tape? or.......?

Thanks

There are several wiring guides posted up around the site

If you connect two 12V fans in series across a 12v supply, you're right- they each will see 6V and will run at half speed.



However, if you connect them in parallel, they both see 12V and spin at full speed.



The yellow wire is for tachometry; a computer uses this to sense the rotation speed or to sense if the fan has failed. You can safely snip it when using computer fans for ventilation.

Personally, I prefer wiring with wire nut connectors, but electrical tape serves its purpose just fine. You can also use heat shrink tubing.

These are the PC fans i use in a mother box.

They kick ass.

If you have any old ROUTERS lying around from changing ISP's then the adaptor they come with is usually a 12v 1000mA style and great for running 2 of these fans.

How would i be-able to connect the one red wire to both fans, and the same for a black wire?



Like the drawing?

i understand from that drawing

If i do it at half speed, can i just tape the two wires together?

Ok here is what you do.

You take your adaptor and cut the connector off the end leaving the plug for the wall and the 2 wires.

then you twist however many black and red wires you have to each of the wires from the adaptor. You can then Electrical tape them to stop the RED touching the BLACK wires.


If you want to run the fan i showed you on half speed you just have to connect the YELLOW wire to the RED wire and hey presto the fan runs at half speed.


Or you could use electrical connector blocks. Blacks into one side and Reds into the other.


I cant believe you dont know how to connect 2 wires to 1 wire. just put them together like " lll " so that they run parallel with each other and twist the wires together then tape them.



It really aint that hard
