The PHANTEKS C399a CPU watercooler from the Dutch case manufacturer is designed for use with AMD\'s Socket TR4 and their range of Threadripper CPUs. The HEDT CPUs (High End Desktop) from the Texan chip manufacturer require a CPU cooler with an especially large surface area to transfer heat away from the processor effectively. Custom watercooling setups paired with socket TR4 CPU coolers offer an excellent cooling solution for the enthusiast processors of the Ryzen Threadripper series, and improvements in cooling also make overclocking even easier. This cutting edge design also offers, among other benefits, a combination of RGB-LED lighting and extremely high quality materials. The end result is the C399a, a cooler that offers the high quality we have come to expect from Phanteks.

Viton is particularly heat- and chemical resistant, and as such is frequently used in aerospace engineering and the automotive industry as a fuel tank sealant. 5 mm cooling fins are located on the nickel-plated copper base plate, thereby optimising heat transfer. The top of the acrylic cover comes with ports for the 1/4\" thread fittings as well as the RGB-LEDs. The LED strips are concealed beneath particularly durable and robust chrome-plated aluminium and to the right side of the mono-block are located both of the LED strip connectors. Phanteks also offers a steadily growing range of fittings and other accessories to allow users to colour-coordinate the look of their custom watercooling setups. The LED lighting is powered via two thin cables that branch off in a Y-shape, the other end of which can be connected to the motherboard or directly to compatible Phanteks cases. The RGB-LEDs are compatible with motherboards using either ASUS Aura Sync, Gigabyte RGB Fusion or MSI Mystic Light. Note: This product comes without the necessary fittings. These fittings are available for purchase separately.
