For the price they are great. Obviously the airflow will be less than some of the best brand fans but that goes without saying. My setup is still cool and you can usually setup them via software or BIOS. The lighting is ok as it changes with the fan speed. It makes sense that higher RPM = more power delivered, so it shines a little brighter. It's really noticeable when you spin the fans slower, they get pretty dim. Overall, for the price and number of fans (5!), you can't go wrong. Lighting is ok. CFM (airflow) is fine. All decent qualities - not the best and certainly not the worst.
