In this watercool heatkiller iv pro CPU review, we look at a cold plate built for modern AMD systems. This component uses acetal plastic for its main body, which offers a distinct look and feel compared to traditional metal blocks. It is designed to fit both AM4 and AM5 sockets, making it versatile for current and recent platforms. The block features a high-flow internal design with larger jets to improve coolant movement. These specifications define its role as a practical upgrade for custom loops that prioritize flow and material choice over pure thermal mass.

What stands out

  • Compatible with AMD AM4 and AM5 sockets
  • Constructed from durable acetal material
  • High-flow design with integrated jet structure
  • Supports 16/10 and 19/13 fittings

Who it fits

Good fit for

This block suits builders who prefer non-metallic cold plates for aesthetic reasons or specific chemical compatibility in their loop. It is ideal for users with AM4 or AM5 processors who want improved flow dynamics without a heavy metal block. The compatibility with 16/10 and 19/13 fittings makes it a good fit for those using standard tubing sizes. If you value a clean, white acetal look and reliable socket support, this unit fits your build needs.

Who should skip it

You should look elsewhere if you need a block for Intel sockets, as this model only supports AMD AM4 and AM5. If you prefer the traditional look and heat capacity of copper or nickel-plated brass, the acetal material may not meet your expectations. Users requiring compatibility with older AMD sockets like AM3 or FM2 will not find support here, despite the broader feature list. This product is strictly for the specified modern AMD platforms.

Verdict: The Watercool HEATKILLER IV PRO Acetal is a specialized cold plate for AMD AM4 and AM5 users who want high flow and a plastic body. It fits specific aesthetic and material preferences well.

Key specs explained for this block

Socket Compatibility: AM4, AM5

This block fits current AMD platforms. You can install it on Ryzen 3000 through 9000 series CPUs. It ensures physical fitment for modern motherboards. If you use older AM4 boards, it still works. This compatibility covers the majority of desktop users. Check your motherboard socket before buying. It avoids the need for separate SKUs for new and old chips.

Material: Acetal

The main body uses acetal plastic, not metal. This creates a unique aesthetic compared to standard nickel-plated blocks. Acetal is lightweight and corrosion-resistant. It may feel less premium than copper or brass. However, it offers good thermal conductivity for its weight. This choice suits builders who prefer a specific look. It also reduces overall system weight.

Weight: 0.32 kilograms

The block weighs 320 grams. This is relatively light for a CPU cooler. It reduces stress on the motherboard socket. Heavy metal blocks can sag over time. This lighter weight helps maintain stable contact pressure. It is easier to handle during installation. You do not need additional support brackets for most boards. It keeps the overall build weight down.

Color: Black

The finish is black. This matches most modern PC cases and components. It provides a clean, understated look. It blends well with dark-themed builds. You do not need to worry about color clashes with other parts. It offers a professional appearance. This neutral color suits both gaming and workstation setups. It hides minor dust accumulation better than shiny metals.

Design and Build Details

The listing specifies that the main body is made from acetal. This material choice gives the block a distinct appearance compared to standard metal cold plates. According to the listing, the color is black. This finish is uniform across the visible surfaces. It provides a clean aesthetic that blends with most modern builds. The material choice suggests a focus on weight reduction and corrosion resistance.

Dimensions are listed as 2.6 inches in width, 2.32 inches in length, and 0.67 inches in height. The weight is 0.32 kilograms. These measurements indicate a compact footprint. It fits well within standard tower coolers or open-loop configurations. The low profile means it will not interfere with nearby RAM modules on most motherboards.

The model number is 18018. This identifier helps you verify exact fitment on your specific motherboard. The layout is designed for direct integration. The cooling structure has no separate jet plate. The jet is integrated directly into the cooler. This design aims to improve flow performance and reliability. You get higher flow rates due to the bigger jet structure. The build is straightforward with no complex moving parts. It relies on simple mechanical installation.

Setup and Daily Usage Guide

The HEATKILLER IV PRO is designed for straightforward integration into custom loops. Its physical dimensions are 2.6 inches in width, 2.32 inches in length, and 0.67 inches in height. The unit weighs 0.32 kilograms. These compact measurements help it clear surrounding components on most AM4 and AM5 motherboards. You must verify clearance for your specific CPU cooler shroud or RAM modules before installation.

Setup relies on the provided socket compatibility for AMD platforms. The block supports AM4 and AM5 sockets, covering Ryzen processors from the 3000 series through the latest 9000 series. It also lists support for older sockets like 939, 940, AM2, AM2+, AM3, AM3+, FM2, and FM2+. This broad range ensures you can use it with a wide variety of legacy or current hardware. The mounting hardware must align with your motherboard’s hole pattern.

In daily use, the block features a real high flow design. This is achieved through a bigger jet structure and receptacles. The listing states this allows for higher flow performance compared to previous models. The cooling structure has improved reliability because the jet is directly integrated into the cooler, removing the separate jet plate. This design change simplifies the internal fluid path.

You can connect 16/10 and 19/13 fittings directly to the block. This improved fittings compatibility gives you flexibility in tubing choice. The block promises up to a 3 degree Celsius temperature decrease compared to its predecessor. This specification suggests efficient heat transfer during sustained loads. The acetal body provides a distinct aesthetic while maintaining functional fluid dynamics.

Before You Buy This Block

You need a compatible pump and tubing for this block. The listing notes support for 16/10 and 19/13 fittings. Verify your existing hose or barb sizes match these inner diameters. You must also ensure your reservoir and pump provide adequate flow. The block uses a high-flow design with integrated jets. This requires clean coolant to prevent clogging. Acetal plastic is durable but can scratch. Use mild soap for cleaning. Do not use abrasive pads. This block sits alongside all-metal options. It offers a lighter weight at 0.32 kilograms. You should check if your case has enough clearance. The height is 0.67 inches. This is relatively low. It fits well in tight spaces. However, you must verify motherboard spacing. The AM5 socket is new. Ensure your cooler bracket is included or available. This setup requires careful planning. You are building a loop, not plugging in an AIO. Check all connections before filling. The acetal body does not conduct heat like copper. It relies on the internal cold plate. Ensure that interface is clean. This product suits those who prefer specific materials or weight savings. It is not for plug-and-play users.

Check before you buy

  • Verify your tubing fits 16/10 or 19/13 fittings.
  • Check if AM5 mounting hardware is included.
  • Ensure your pump supports high-flow loop designs.
  • Confirm case clearance for 0.67 inch height.
