Review on 🌈 Apevia TL612L2S-RGB Twilight 120mm Silent Dual-Ring Addressable RGB Color Changing LED Fan: Remote Control, 28x LEDs, 8X Anti-Vibration Rubber Pads, 2 Magnetic LED Strips (6+2-pk) by Brian Mendoza

They are very loud. Apevia copies and pastes the same "24.7dB" noise levels in the descriptions of all of its fans, despite their different designs. I doubt they do noise testing at all, of course the number given is not accurate as it would be almost silent, when in reality they are pretty loud all the time and always run at the same speed regardless of your system temperature. If you play with headphones or keep your computer a few feet under a table, the noise can be tolerable, but personally I've had to ditch them and buy quieter fans. Too bad because they look beautiful.
