WaterCool announced retail availability of HeatKiller IV water-blocks for AMD Ryzen Threadripper processors. Designed for AMD sockets TR4 and SP3r2, with micro-fin lattices at just the right places to effectively cool the active dies of the Threadripper MCM, the block comes in four variants - Pure Copper, Copper-Nickel, Acryl-Nickel Black, and Acryl-Nickel Red. The Pure Copper variant combines an exposed copper main block with a copper top; the Nickel-Copper variant is nearly identical to this, except the block and top are nickel-plated; the Acryl-Nickel Black combines a nickel-plated copper main block with an acrylic top that's been framed by black anodized aluminium, while the Acryl-Nickel Red is its twin with a red colored frame.

The Pure Copper and Copper-Nickel variants boast of a staggering 1 kg weight (that's a lot for a water-block). The acrylic variants are a little over half the weight. Besides being see-through, the Acrylic variants are studded with RGB LED strips that have a standard 4-pin RGB header. All variants measure 118 mm x 78 mm x 18 mm, and feature standardized G 1/4-inch ports (fittings not included). There's a healthy 25 mm gap between the two ports so you can dabble with some of the fancier fittings in the market. The Pure Copper variant is priced at 89.95€, while the Nickel-Copper, Acryl-Nickel Black, and Acryl-Nickel Red are priced at 99.95€ (prices include taxes).
