## Long description

Thermaltake CL-W139-CU00SW-A is a black CPU water block designed for integration into custom liquid-cooling loops. With a solid copper contact area and a finished housing in black, this water block provides direct-contact heat transfer to the coolant. It supports a wide range of Intel and AMD sockets, making it suitable for high-performance desktops and workstations that require efficient processor cooling. The unit weighs 0.67 kg and is intended for use in custom water-cooling systems where compatibility, straightforward installation and reliable thermal performance are required.
Advantages
The water block offers broad socket compatibility covering modern Intel LGA and many legacy sockets as well as AMD AM4/AM3+/AM3/AM2+/AM2/FM2/FM1 platforms, reducing the need to change components when upgrading a CPU or motherboard. Its copper contact and solid construction ensure effective heat transfer to the coolant loop while the black finish integrates visually with a variety of system builds. The compact design simplifies placement inside typical custom water-cooling loops and works with standard G1/4 fittings for flexible tubing and connector choices.
Suitable for
 Custom PC water-cooling loops in gaming desktops and workstations
 High-performance systems requiring direct-contact CPU cooling

How to use
Prior to installation, flush and rinse radiators, tubing and the water block with distilled water to remove manufacturing residues. Mount the water block to the CPU following the motherboard and block manufacturer instructions for the supported socket, using the supplied or compatible mounting hardware and correct thermal interface material. Connect inlet and outlet ports using compatible G1/4 fittings and tubing, secure all fittings, then fill the loop with an appropriate, market-proven premix coolant. Power the pump briefly with the system off to circulate coolant and check for leaks before fully powering the PC.
Usage recommendations
Use a proven premix coolant that includes corrosion inhibitors to protect copper, nickel, brass, aluminum and other loop components. Run the loop with the fill port open for an initial bleed period (about 24 hours) to remove trapped air, and check all seals and fittings for leaks with paper towels placed beneath joints. Avoid running the pump dry and perform routine maintenance by flushing and refilling the loop when coolant appears degraded.
