7V to 12V(and vise versa) at the flick of a switch

post #1 of 11
Thread Starter 
idea; a button that makes the fans run at 7V when turned on, and 12V when off(or vise versa). I realy want to get rid of that damn fan controller and instead have only 1 button to worry about(shuld be able to run hign number of fans).

my question; does anyone know how to connect the wires and what kind of switch to use?

I was thinking more of modifying all fans to one switch instead of having one switch for each fan.

However i found a great guide for this on silentpcreview.com

a simple 2 way selector switch, you'll want to buy a high amperage one if you plan on running a lot of fans off of it

What about a high amperage slider so that you can set as fast and slow with out pre-sets, either that or a fan controller for a drive bay or something.

Just a thought, lol I don't know if it's very practical but it might be worth a try. (I'm a little new XD)

You gave me an idea! Have a PC charged battery in the CD drive Bay and when the PC is off, flip the switch and you can run all the fans in the PC for 5 minutes after it turns off, to cool it down faster!

honestly i'd rather have some kind of fan controller it saves me a lot of work, but it also depends on what kind of fans you are planning one running, if you are modding the maybe just pick up something like a pci slot fan controller(like the sunbeam rheosmart one) and drill a hole for it where you want it mount it and be done

the fans I'm running are GT AP-15's. I think my new case will take 19 fans total(remains to be seen, still waiting for delivery). The thought however is to reduse the amount of switches to a minimum, I have a fan controller today, but having to adjust each fan individualy is a pain in my ***. I had my pc crash once because I forgot to turn the fans up when gaming(stupid mistake).

ap-15's have a starting current of .36 amps that's the part that will kill a controller, i'd probably set up zones on a high current fan controller
something like this http://www.performance-pcs.com/catal...ducts_id=24896
or this http://www.frozencpu.com/products/14...?tl=g47c17s817

or you could get something like this http://www.performance-pcs.com/catal...ducts_id=30058 and just connect it to one of the pwm headers on your motherboard and control them like that

they dont sell those fan controllers in norway, so i would have to import and pay norwegian tax(25% of product AND shipping cost) to get it into the country And its not quite what i asked for anyway :/


EDIT: difficult to locate heavy duty DPDT switches within norway... would it work if i used 3 heavy duty SPST switches and connected 5V, 7V and 12V to each switch?
