Software does not work
In my system i right now had the older rgb ring fans. They worked fine but it was rather stressful taking off the side of the case just to change the color or speed of them. So once i realized that these fans could be changed with software, i returned my older rgb fans and purchased the newer premium ones. I simply wish i would have been able to read more reviews before i purchased them. As for the fans themselves, they are very good fans and actually i purchased them almost exclusively for the software control, which is where my issue lies. I am a computer technician, and not a self proclaimed at home tech, my day job is computer repair. The software provided from thermaltake does not recognize the fans so i cannot adjust the color, speed or anything. Upon reading about this, it is a very big problem with these fans that many people are having. I just wanted to let someone know so that they may be informed before purchasing and be able to make an educated decision. You may have good luck, you may not. Consider yourself warned.
