Watercool HEATKILLER IV PRO CPU Water Block

While it removes a common restriction point, the HEATKILLER IV PRO compensates by using a highly sophisticated micro-fin structure. This design maintains excellent thermal transfer while significantly reducing flow resistance, making it an ideal choice if you want to run a quieter pump at lower speeds.

This model is compatible with a wide range of AMD sockets, including 939, 940, AM2, AM2+, AM3, AM3+, FM2, FM2+, and AM4. Please double-check your motherboard's socket type before purchasing to ensure a perfect fit.

Yes, the block is designed with a 25mm thread distance, which accommodates large fittings up to 19/13 size. This makes it quite versatile for custom loops using thicker tubing.

The block uses high-quality PLEXIGLAS GS, which is durable and resistant to the common issues found in cheaper plastics. However, as with all acrylic components, avoid using aggressive cleaning agents or alcohol-based coolants, as these can cause micro-cracking over time.

Not necessarily. Because the internal design is optimized for low flow resistance, this block performs efficiently even with lower-performing pumps. It is a great option if you are trying to keep your loop noise levels down.
