Review on 🌈 EZDIY-FAB 5V ARGB Memory Cooling Vest for DDR3 DDR4 - Enhance Performance with RGB Ram Heatsink & Shine Lighting Bar (2 Pack) by Andrew Grant

Have been using them since I got them in April. I'm sure they do what is advertised. My only issue with them is that there isn't a purchase option for those who need more than two. And as you can see from the photos, they aren't that bright. The fans in my PC are off the shelf. The GPU slack mount I bought from Revain fits my fans. These coolers are not as bright and two of them are darker than the rest (coolers 1 and 4). And before anyone says yes I used ASRock's software to make everything white and that's what the coolers are outputting. If the coolers match my fans and GPU mount I'd say they're a must, but if you don't mind the color variation I'd recommend them.
