Built for sustained thermal loads in AI workstations and servers, the PCCOOLER LR Series combines thick radiators, high-speed PWM fans and large-format cold plates. The four-model lineup makes selection straightforward: choose 360 mm or 480 mm radiator capacity, then select single-CPU or dual-CPU coverage.

At a Glance

How to Choose

Choose an S model for a single-socket workstation or server. Choose a D model when one cooling loop must serve a dual-socket platform. Within either configuration, the 360 mm models offer a more compact installation footprint, while the 480 mm models add a fourth 120 mm fan and a larger heat-exchange area for higher sustained cooling demand.

LR360S - Compact Single-CPU Performance

The LR360S is the streamlined choice for high-performance single-socket systems. Its 397 x 120 x 38 mm aluminium radiator pairs with three 120 mm dual-ball-bearing PWM fans, each rated for speeds from 500 to 3000 RPM, airflow up to 99 CFM and static pressure up to 5.33 mmH2O. A 2600 RPM pump and large 84 x 76 x 43 mm water block support dependable heat transfer under extended workloads.

Best for: single-CPU AI workstations, rendering systems and servers that require strong cooling in a 360 mm mounting format.

LR360D - Dual-CPU Cooling in a 360 mm Format

Designed for dual-socket platforms, the LR360D extends the 360 mm architecture with two water blocks and longer 700 mm tubing. It retains the 38 mm-thick radiator and three high-speed 120 mm PWM fans, delivering the same airflow and static-pressure specification as the LR360S while covering two processors in one integrated cooling solution.

Best for: dual-CPU workstations and servers where a 360 mm radiator is the practical fit.

LR480S - Maximum Radiator Area for One CPU

The LR480S increases radiator length to 517 mm and uses four 120 mm fans, giving a single high-power processor more heat-exchange area for sustained full-load operation. The 38 mm-thick aluminium radiator, 2600 RPM pump, large-format water block and dual-ball-bearing fans make it the flagship single-CPU option in the series.

Best for: flagship single-socket AI workstations and high-performance servers with 480 mm radiator support.

LR480D - Flagship Dual-CPU Thermal Coverage

The LR480D combines the largest radiator in the range with dual-CPU coverage. Its 517 x 120 x 38 mm radiator is cooled by four 120 mm PWM fans, while two water blocks and 700 mm tubes support dual-socket layouts. It is the most expansive LR configuration for systems designed around continuous, high-density compute loads.

Best for: dual-socket AI, simulation, rendering and server platforms where maximum radiator capacity is the priority.

Shared Engineering Across the LR Series

Across all four models, the LR Series uses 38 mm-thick aluminium radiators, 120 mm dual-ball-bearing PWM fans and workstation-class socket support. The common platform is designed for long-duration professional workloads, while radiator size and CPU count define the right model for each system.

Compatibility Note

Supported Intel sockets: LGA3647 (Narrow) and LGA4677 (4710). Supported AMD sockets: sTRX4, sWRX8, TR4, SP3, TR5, SP5 and SP6. Always confirm chassis radiator clearance, motherboard socket spacing and tube routing before installation.
