Anyone know of an adapter that'll convert the molex plug comming from my case fan into a 3 pin female plug that i can plug into my motherboard?

they don't make those because they are likely to kill the motherboard if you try to short the power supply to a fan connector
(but you could build your own by purchasing a normal molex to 3 pin adapter
then chopping the female connector from a old fan then soldering it to the normal adapter.
you will then get a molex to female fan adapter that you can plug into the motherboard and enjoy a nice light show that the motherboard will put on for you. (PS the fan connector on a motherboard only gives around 5 watts of power and does not give out a completely stable output (cost cutting measure since fans do not need to meet strict line ripple specs)

You really aren't suppose to do something like this. You can easily damage your motherboard if the fan tries to draw to much power. I would advise against using this method, and instead look into getting one of these...
This will allow you to connect the fan to the power supply instead. Just use it on a molex plug that is connected to a hard drive or CD drive. It should be a lot safer then the method you were thinking of using.
