Darkflash GAUS24 Magnetic ARGB 120mm PWM PC Case fans, 3in1 Pack, up to 2000RPM High Speed Rotation, Included FDB Hydro Bearing, 9-Blade Design, 33dB(A) Low noise, Case Cooling Fan

The LEDs look nice, and the fans themselves work well. I have the G16 which only has RGB along the side, if you want RGB with the fan blades you'll have to get the more expensive G24s. The fans themselves feel very well built, the magnets that connect between the fans aren't very strong, so they won't stay together in a single unit (this isn't an issue when the fans are mounted in a case or on an AIO). Two downsides are the large size of the magnetic headers that either connect between fans or connect the fans to a ARGB + PWM output (it does include daisy chaining on both the ARGB and the PWN fan header), they're pretty massive. The second is even though the product pictures show color matching cables for the white fans, the cables included in my fans are black. Usually this isn't a major issue, but if you have a case where you're wiring cables across different sets, then the cables not color-matching might ruin your aesthetics. Overall, the price is relatively competitive for unifan-style fans, but if you're an experienced builder who's okay with cable management, a 3-pack of Thermalright ARGB fans are far cheaper than this.

They are really nice looking fans, however, they don't have a built-in RGB controller, so if you don't have any available 3V ARGB headers on your motherboard (either what you have is in use with other RGB hardware) or don't have them at all or don't have a external ARGB controller provided by the case manufacturer or 3rd party, then these will spin, but not light up. At the minimum, they should at least turn to a default white. 1 star off for that, 2nd star because of the white fans should could with a white power cable, but they come in black and it's pretty large too.
