Whether you're building your first PC or are a veteran builder, keeping your essential components running at optimal temperatures is a high priority. The best all-in-one liquid coolers give you a balance between performance, heat dissipation, and style. Many new models like the NZXT Kraken X62 at Amazon have customizable RGB lighting with on-board controls or through compatible apps; you can also use apps and dedicated programs to monitor performance and temperatures or adjust settings on-the-fly. The newest models have LCD displays on the pump housings to give you critical information at-a-glance or show off your personality with gifs, text, and images. All-in-one units like the EVGA CLC 240 at Amazon are perfect for liquid cooling newbies since they come pre-filled and sealed to save you the hassle of setting up coolant reservoirs and dealing with leaking tubes; veteran builders will also love the easy installation that lets them spend more time on quality control of components and cable management than wrestling with frustrating liquid cooling set-ups.
These kinds of coolers are also designed for quiet and near-silent operation, using hydraulic or dual-ball bearings to reduce friction at higher RPMs and keep potentially distracting fan noise to a minimum. No matter if it's your first build or 101st, there is an AIO cooler to suit your needs. We've gathered up our top picks from brands like NZXT, Aorus, and Corsair, and we'll break down features and tech specs to help you decide which is best for your build.
