Watercool HEATKILLER IV PRO AM4 Acryl Clean CPU

This Watercool CPU block is a copper water-cooling component with a clear acrylic top designed for custom-loop builders. It supports AMD desktop sockets including AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, 939 and 940. The block uses a tool-free Easy-Mount-System for installation.

Suited for AMD custom-loop builders.

This block suits builders assembling a custom loop on supported AMD desktop sockets who value tool-free mounting and high flow. It does not fit Intel sockets, so buyers with LGA platforms must choose a different block.

25 mm thread spacing enables 16/10

The revised cooling structure integrates the jet directly into the cooler without a separate jet plate, while larger receptacles and a bigger jet structure raise flow performance. Fittings with 16/10 or 19/13 dimensions are compatible thanks to the 25 mm thread distance.

Questions about this item

Does the copper cold plate need periodic cleaning or replacement?

The copper block has no user-serviceable parts; only the O-rings on the G1/4 ports may need replacement if they degrade.

What limits sustained cooling performance first — flow restriction or thermal saturation?

The revised micro-fin structure and larger jet receptacles raise the thermal limit, so flow restriction from the loop becomes the first bottleneck.

How much pump head is required to run this block all day without noise issues?

The high-flow design works with standard D5 or DDC pumps; no extra pump head is needed beyond normal loop pressure drop.
