Ok, i think i got it figured out now.

What if i put the LEDs in parrallel, so they dont get so much current, I think that would work, but then would i have to still put a resistor in the parrallel bit of the LED so it doesnt blow up?

Also-

I would just use a 12v supply, and put a resistor in one of the options of the switch. That would alow less current to go through = slower fans = more quiet (did that make any sence?)does anyone know what types of resistor(s) i would have to use?

Here are what the following circuits will:

2x 120mm fans
1x 120mm fans
2x 80mm fans

Could i use the same type of resistor for all the circuits?

Thanks guys, i am hopeless at this (hence my name)

Attatched is a 'updated'fan circuit layout.

Well if you hooked up the led's that way they would never turn on. Remember, electricity is lazy. If it doesn't have to pass threw something it woun't.
