I had similar fans in my raidmax neon rgb case.
The fans didnt have RGB software,they were only controlled by the case button,and that was only for changing colors,not speeds.
The fan connects via molex,which means it will run on 100% all the time,so i'd say that your chances of it having a software are very low.
