Overview

The RAIJINTEK 0R40B00084 CWB TR4-RBW RGB CPU TR4 Cooler Water Cooling CPU - Water Block is a dedicated CPU water block designed for AMD's TR4 (Threadripper) socket. It features a copper base and RGB LED support, making it suitable for custom water cooling loops. With a power consumption of 35W and a noise level of 20dB, this block aims for quiet operation. For enthusiasts building a custom loop around a Threadripper CPU, this water block provides a reliable and visually appealing option.

Key Features

RGB LED Support: The block uses a 5V addressable RGB connector, allowing synchronization with motherboard RGB controllers for customizable lighting effects. This is ideal for users who care about aesthetics inside their PC case. Copper Base: The high thermal conductivity of the copper base ensures efficient heat transfer from the CPU to the coolant, critical for cooling large Threadripper dies. Quiet Operation: Rated at 20dB, the block itself is very quiet; overall system noise depends on the pump and radiator chosen, enabling a silent build. TR4 Socket Specific: This water block is designed exclusively for AMD TR4 (Threadripper) sockets. It does not fit other sockets like AM4 or LGA, so verify compatibility before purchase.

Connectivity & Compatibility

This product is compatible only with AMD SocketTR4 (TR4). It uses standard G1/4 inch fittings, allowing connection to common water cooling tubes and radiators. The RGB connector is a 3-pin 5V addressable RGB header, compatible with most modern motherboards that support such headers. The package includes a TR4 mounting kit; no other socket mounts are provided.

Note that a pump, radiator, and tubing are required separately for a complete custom loop.

Best Use Cases

PC builders using AMD Threadripper (TR4) CPU: Ideal for those constructing a custom water cooling loop for their workstation or high-end desktop. The dedicated TR4 design ensures proper coverage and efficient cooling. Noise-conscious enthusiasts: With its low 20dB noise rating and the ability to choose silent components, this block suits those aiming for a near-silent system. * Budget-conscious custom loop builders: This water block offers a cost-effective entry point for TR4 water cooling, though it lacks support for newer Threadripper Pro sockets (sWRX8). Always confirm your CPU's socket generation before purchase.
