Overall Review: Installation was easy and way better airflow from my old hd120s and hd140s. Make sure you're motherboard has 5v argb headers. If not it does come with a controller connects to sata. Edit: After 2 months of use for the black ones I bought for my husband's build, one fan's bearings went bad. The fan was un-balanced. These come with a 2 year warranty; I've already contacted Lian Li and they are going to send a new fan. I still like these way better, but QC needs to be more tested to be sure that doesn't happen again.
