Hi All. I was thinking of adding another fan to one of my boxes that sit in a cabinet. I want it to run, off of the thermostat that the original fires off of, so that it remains off and quiet until it's needed. But I'm wondering if anyone else has powered an added fan from the original power leads for the stock fan.

Also, the fans supplied have two speeds? Low and high?
Looking around, I can get this:
hxxp://www.google.com/products/catalog?hl=en&biw=1243&bih=595&wrapid=tlif129581507599310&q=pc+fan+cable+3+pin&um=1&ie=UTF-8&cid=1398322886258812174&ei=0JE8TeWgM5G6sQO818nGAw&sa=X&oi=product_catalog_result
&ct=result&resnum=6&ved=0CIwBEPMCMAU#
Which will allow me to split the power source to two three pin (HDMI Model) fans.

I think I've seen it. But that's for the 12V mod, I think. Plus, it would be always on. That's what I'm trying to get away from.

Jumping the power from the stock fans would get the same control (low and high) as the stock fans. Motherboard controlled power based on temp.

Here's a link to help you understand

If you want you can make it nice and clean by installing a 3 pin connector on the motherboard.
Here's the link for that

Then instead of connecting power like it says in the tutorial you can borrow power from the transistor.
In theory this will work, but i've never tried it. Good luck
Thanks for the great info! Great links.
Is the stock fan header just like a PC fan header? So, if I use a fan splitter three pin, and keep the original fan, then add another 90mm fan?

Well, I bought about six each of the 3 pin female (1x) to three pin male (2x)adapters, plus 90mm fans (Antec Clear) and am going to tap into the the 12v rail under the back of the board, near the power plug. I just need to look at the three wires and where they need to go. Think I only have to do two of them. I think it's x2 12v and one ground. I think the two 12v, are in case the wiring on the fan for power is different -- depending on the fan. I still want to use a thermostat. It's just that the three hole stock fan header will overload if I add a fan there. This way, I'll be able to have room for two fans, with quick disconnects when I have to crack them open, for whatever reason... I need to figure out where to get a 12v thermostat now.
