These Corsair QL120 GDB fans are in excellent physical condition and fully operational. They will keep your case cool and provide beautiful RGB lighting. Some LED colors are no longer correct, so do not buy this if you are trying to get perfect color lighting. But it you want to use it for a rainbow or spend some time figuring out which colors look right, then this is a great deal. Note that the iCUE Lighting Node CORE does not ship with these fans, so you'll need to have one already or independently acquire one.
