The black copper PVD top

This is Watercool's latest HEATKILLER IV in Black Copper PVD. Its top features a high-quality, black, diamond-like carbon coating (Diamond Like Carbon, DLC), applied using a modern plasma process. Watercool describes the surface as extremely hard and wear-resistant. It says the surface provides a stunning deep black appearance while offering optimal protection and long-lasting quality.

What changed in the HEATKILLER IV

Against the previous model, or predecessor, Watercool lists these points:

• Up to 3 °C better temperatures and cooling performance
• Increased flow rate thanks to a larger nozzle and collection channel (bigger jet plate nozzle and channel layout), resulting in fewer blockages and less clogging
• Tool-free Easy Mount system
• Extra large connectors and fittings thanks to 25 mm spacing

New cooling structure and optimized flow

The cooling structure, which Watercool also calls the cooling engine, underwent the most significant redesign. Watercool equipped the cooler with considerably finer, thinner fins to provide a larger surface area and thus better heat dissipation. It also ensured that the fins were designed in such a way that the flow was not compromised.

Compared to the previous model, Watercool eliminated the nozzle plate (jet plate) and integrated it directly into the lid. Watercool writes that this innovative design "allowed us to increase performance", improve flow and optimize reliability.
