Do 4-pin RGB LEDs (12v maybe) exist standalone?

[WhitetailAni]

I was looking more at my case, and decided to see if I could figure out why the LEDs on my side fan stopped working.

Turns out that they're dead.

Dead as dead can be.

Not even a spark.

They don't even complete a circuit.

But I had a thought while removing them: 

Could I put some RGB LEDs (not strips, mind you, just standalone LEDs) and mod it into an RGB fan?
The holes seem to be "standard", meaning I could grab one of those 4-pin RGB LEDs and stick it in there. I think I have one, but I can't find it, and it may have been at a friend's. Don't remember.

I can see one problem:

12 volts.

My 4-pin headers provide 12 volts, and I don't think the ubiquitous RGB LEDs that are in every Arduino kit everywhere take 12V - I'd probably end up making a mini explosion.

So does anyone know if such a thing exists?

I do have resistors in 330 ohm and 1K ohm variants - and at least 4 of each kind if that's what I'll have to do.

there are some 4 pole RGB leds on the market, most run 2 - 3.2v and some "led modules" running 5v with on board resistors for each colour. I haven't seen any 12v native RGB LEDs

I'm not sure if it works this way (I haven't fiddled around with this kind of thing in awhile, and the highest voltage I ever used was 5v because that's the highest my Pi provided), but can I use resistors (1K and/or 330 ohm) to make them last longer than 2 seconds?
Or even crazier - 12v to 3.3v transformer, then 3.3v to 12v transformer all in a little box?
