Review on 🌈 Experience Stunning RGB Lighting with EZDIY-FAB Dual Ring 120mm Case Fans - Sync with 5V Motherboard, Adjustable Speed, 10-Port Fan Hub X, and Remote Control - 3 Pack by Mike Gruwell

Great fans for the price. My ONLY complaint is that when I placed them on top of the case as an air intake they all started making this weird buzz. I tested this with my other ring fans that came with my case and there was no such issue. and also the problem disappeared when i used them as an exhaust at the top instead. Strange issue, but overall they're not bad. The RGB sync works with the RGB hub that came with my case, but if you plug the included hub into your MOBO's 5V RGB jack, you'll probably need RGB management software to control it ( I haven't tested it yet).
