There are two possibilities for this. The most common is a stuck relay causing the fan to get voltage. Under the hood there is a relay box on the left (drivers) side. Pop off the top cover and find 2 fan relays. One relay is for the regular coolant fan which is on the left(driver). The other relay may say ac fan which controls the fan on the right. If removing these relays doesn't stop the fan there is a possibe electrical wiring problem. Check with a Kia dealer and if you are under 60k miles it should be under warranty.
