There were no shortage of RGB fans at CES 2019, but one we really liked was the Cooler Master MasterFan SF-120P ARGB. It features 24 ARGB LEDs which are not only in the center of the fan, but around the frame as well.
About 10 years of computer experience. Been messing around with electronics since I was 5, got into computers when I was in highschool, been modding them ever since then. Very interested in how things work and their design.
