maybe a resistor?
it might work, i have never over volted a led.
could you measure the current the fan led draws and i could tell you the resistor size.
or use 3 diodes this will drop the voltage by 1.8V to there will be about 10.2 for the fans
Thank you, Bradey ... to confirm, yes, this is the LED switch on the front bezel. Also, for now, I would be powering 2 fans each with 4 blue LEDs for a total of 8 blue LEDs (I believe blue requires a tad more voltage than red or green). Soon though I'd like to power 3 fans for a total of 12 blue LEDs.
Given this, do you think I would still need to make use of a resistor, diode, or some other voltage sapping mechanism?
I guess one thing I need to clear up is whether the LEDs in the fans are in series or parallel - I'm going to guess I'm out of luck and that they are in parallel in which case the blue LEDs, as I understand, are at 3.4V meaning I'm overvolting by nearly double for each fan assuming I've only got 2 fans hooked up to this thing? ... hmmm ... better get me some more blue LED fans lols!
Seriously though, is this accurate?
The schematic posted earlier for reference ...
Uhm ... yeah, that was me in that post with the relay schematic.
I was just thinking I could use a terminal block to kill 2 birds with 1 stone - 1) be able to control ALL lighting in my case and 2) not have to use a relay or transistor to manipulate the switch.Edited by the.ronin - 3/19/10 at 4:28pm
