AM4 Water Block Upgrade Kit

This Thermaltake water block is designed for AM4 socket compatibility and serves as an upgrade component for custom liquid cooling loops. It targets builders who want to integrate an AM4 processor into an existing open-loop system using a black-finished block.

Direct Socket Mount Installation

The block mounts directly onto the AM4 retention mechanism using the supplied hardware. Alignment of the micro-channel cold plate with the processor heat spreader is critical; uneven pressure can leave hot spots. No radiator, pump or tubing is included, so the installer must already have those loop components ready.

Verify AM4 Socket And Loop Readiness

Confirm the motherboard uses the standard AM4 mounting pattern and that sufficient clearance exists around the socket for the block and its fittings. Ensure your loop uses compatible G1/4 thread fittings and that coolant, pump and radiator capacity are already planned for the thermal load.

Questions about this item

How can I confirm the water block is seated correctly on my AM4 socket after installation?

Verify that the mounting hardware aligns with the AM4 retention bracket and that the block makes full, even contact with the processor heat spreader; monitor coolant temperatures to ensure they stabilise within expected ranges.

What components are included with the CL-O011-CLSTSL-A and what must I source separately?

The package contains the black water block and AM4 mounting hardware; you will need to supply your own radiator, pump, tubing, fittings and coolant to complete a custom loop.

Which version of this water block should I choose for an AM4 platform?

The CL-O011-CLSTSL-A is the sole AM4-compatible variant listed, so select this model for any socket AM4 build.
