Anyone have the link to that site that has a guide on makeing 7/12V fan switches?

I wanna mount the switches on a 5 1/2 drive cover of my case and be able to turn down the fans as I go to sleep.

thanks, i rmemeber seeing another guide that included lights, i was hopeing to find the link to that, would be pretty cool with different leds.

http://www.3dgameforce.com had a good switch guide a while back, and they did an awesome job setting up 2 led's per switch.

thanks alot, this is exactly what I was looking for, Im gonna go to radio shack and get the parts, just took apart an OLD CD-ROM to use as a base and hold this project.

here's another, i'm doing this one at the moment but a little different. i'm not fitting the lights and i'm not fitting the switches in a drive bay, i'm fitting then too my front face plate.

Hmm, just wondering ...
Am I right to think that I can just place a swithch between 5V and ground, so that the fans will run either 12V (12-0 ground) or 7V (12-5) ?
I won't get the pretty LEDs but, it seem like the easiest solution.

CHHASmatroxuser - 5v and ground? that'll give you errr...not enough juice i think. To make 7v work, follow the guide over at VH. He does a better job than me when taking pics and explaining things

 

[Mikewarrior2]

some fans will turn if they hvae 5volts going through them, other's will not(a Sunon HO 80mm comes to mind as one of those that won't).

[helloedchen]

wait...your right MW2...they do turn at 5v

i totally misread that one!

 

[DarkManX]

im such an idiot, I got all the parts, and did everything this guide said, http://www.3dgameforce.com/articles/fantoggles/ before having to hookup the power I realized this isnt for voltage switch, but for on/off im such a moron, I spent close to 40$ on parts, now I stuck with useless on off switches with leds which wont do me any good to turn of my CPU fans which cause the most noise, anyone know how I can turn this into voltage switch? Or anyone interesting in buying it? I will sell it fully assembled and all mouted inside a CD-ROM case.

darkmanX, i just bought my switches but they gave me the wrong ones as well, there just on/off. i'm going to use them though. so they'll be 7v/12v which i hope will lower the noise a heap anyway. i didn't like the option of switching the cpu fans off also.

 

[Mikewarrior2]

can't you return the switches?

i'm using Radio Shack SPDT switches.

GideonX:

What I meant was to let the 12V wire run to the fan as usual, and place a switch, so that it controls which wire connects to the other fan wire, either the 5V or the 0V wire, thus giving me either

Setting 1: wire 1 12V wire 2 0V result 12V
Setting 2: wire 1 12V wire 2 5V result 7V

Well .... guess I sorta answered my own question

i built the 7v/12v fanbus switch project like the one at virtual hideout did but a little different. i had no off setting so it was just 7v/12v and i didn't fit the LED's. what happened was when testing it it worked fine, i started it at 12v switched it too 7v fine back to 12v but then i flicked both switches to 7v and my power supply died, the fuse went. it's a 235watt octek power supply. i'm pretty sure nothing shorted, is it because the 5v and 12v wire thing?

please help, thanx.

um, you can't MAKE the switches, but the guides in fanbus.com will help. cliff is a great guy.

CHHASmatroxuser, it's fine, i got what you meant the first time... that is 12V at all times, and the switch switches between a circuit with ground for 12V or 5V for 7V. it's fine.

have an LED is more tricky because it requires another "loop" with a resistor.

and there are other more "tricky" things that you can do with LEDs. I will not be implementing these though
