For $30 you get 3 fans and a controller. While unfortunately you can't control your fan speeds via your motherboard, the fan controller's max setting is not too loud compared to a 2080 Super running at 2800 RPM.
My only negative is that it was a little on the tougher side to screw in the fans. I believe this is due to the rubber feet on the fans causing a tight fit. The fans don't budge though and that should be praised.
The RGB control was a tad odd at first but I realized that it needs to be manually changed to M/B on the controllers remote. Then it just immediately synced with my MSI Mystic light.
Airflow is the only thing that is holding this fan set back from being a force to be reckoned with. But they are $10 fans so I am not exactly going to hold that against them. The airflow was enough to normalize my AIO from the original fan set I had.
Overall these fans were worth what I paid for in my opinion, my idle temps on my CPU used to be 45 Celsius but now a comfortable 34 Celsius. I will basically be running these PCs into the dirt and use them until they die.
