Watercool HEATKILLER IV PRO Acetal CPU Water Block

This Watercool HEATKILLER IV PRO Acetal block supports both AM4 and AM5 sockets. It features a copper base with an acetal top, weighing 11.2 ounces. The dimensions are 4.33 inches wide and 1.97 inches tall. You trade the compact 0.91-inch height of the Bykski for a taller profile. The material combines copper for heat transfer with acetal for durability. This option suits users who want high-flow cooling on AMD platforms without the micro-channel design. It provides a straightforward alternative with different aesthetic and dimensional characteristics compared to the original block.

Bykski CPU-RAY-MK-M AM5 Block

The Bykski CPU-RAY-MK-M block also uses a micro-channel design for AM4 and AM5 sockets. It weighs 1.5 pounds, significantly less than the original’s 4 pounds. The dimensions are 3.31 inches wide and 0.94 inches tall. You gain a lighter option with similar cooling technology. The nickel-plated copper base ensures durability and corrosion resistance. This block is a practical choice for users who want high-efficiency cooling without the weight of the original.
