These fans are pretty quiet even at full speed. They came with 8 slots (fans) and 2 slots (RGB strips) and an RGB controller. If your motherboard doesn't support RGB, you have an actual controller. I can't think of anything bad, except maybe the fact that they don't sit flush with the case. In theory this reduces airflow, although it doesn't really matter that much unless you're plugging it into a heatsink, I still wish they were sealed from the case.
