Review on 🌬️ upHere 140mm RGB LED PC Cooling Fan 5-Pack - Ultra Quiet High Airflow for PC Cases with Remote Control - RGB143-5 by Tim Crowder

They don't have the usual 3/4 pin fan connectors. They use a special one that only connects to the inferior fan controller that comes with the kit. When I installed it, only half the colors worked, speed control didn't work, mode selection didn't work, instructions were useless, and build quality was crap. I have a picture of the inside of a fan controller that should be used. The controller can easily be seen from the inside so I opened it up to see it. The fans themselves aren't bad at all, they're quiet and move a decent amount of air. Unfortunately, one of them assumes it after 1 day, which is a pity, because I really like the look of these fans. I won't be returning these fans as they at least move air and $40 isn't bad for that.
