i recently wc my pc. afterwards i connected all my fans to the antec fan lead which runs the fans at a little over 5 volts. the only thing i hear now is the pump

The problem: all the LEDs in all my fans are off due to the low voltages or very dim

The Question: can i run the LEDs in the fans off a seperate wire harness? there are at least 15 LEDs (3 fans of 4 and 1 fan of 3) and if i did this i would probally add a few more elsewhere

i have heard that LEDs like 3 volts can i get this from the power supply or is that a really bad idea? (i'm thinking about the 3.3volt line that powers the CPU) i just cheched and it's rated for 28amps

i have also heard that if you run them in series or parrallel (can't remember which) the voltage to each LED will be determined by #LEDs / volts
so 4 LEDs on a 12 volt circuit would each get 3 volts
this makes sense mathmatically but doesn't sound logical to me

how difficult will it be to wire LEDs in fans to a seperate circuit? is this somthing that it may be easy to buy a bulk pack of LEDs and just replace all the LEDs?
