Review on 🌈 GIM KB-28 RGB Case Fans: 3-Pack White 120mm Cooling LED Fan for PC Case and CPU Cooler - Silent Operation, Colorful Rainbow Lighting, Adjustable Speeds with Hub by Gregory Shorunov

Pros: Inexpensive high CFM fan kit for the price. They are RGB.Cons: This is the definition of non-standard. Custom 7-pin header with no output to a standard 3-pin RGB/4-pin fan, so you can only connect existing fans if they are GiM brand or if you have another brand that is both supported as a connection option. When you plug it in, the only uniform lighting is when the controller has RGB controls. When the motherboard relays messages, only GiM's proprietary materials work properly, and everything else is just thrown around randomly. There's also no feedback from the motherboard to determine current PWM levels or report current RPM, so you can't use this kit stand. -alone, without disabling the BIOS warnings. In that sense, it's not user-friendly at all. To be honest the connectivity support kills this great setup. Headers *act* are important in their strength, but they also need to be able to break through the cable.
