Open-Air Test Bench for Watercooling

The PrimoChill Praxis WetBenchSX Basic Flat Edition is a powdercoated steel open-air test bench designed for watercooled or air-cooled component builds. It suits hardware testers and enthusiasts who need quick assembly and easy hardware swaps. The flat motherboard layout also supports LN2 pot mounting for extreme overclocking sessions. Its modular frame allows the bench to be assembled in minutes.

Radiator and AIO Mounting Capacity

Before ordering, verify that your radiators fit within the supported limits of up to four radiators or two AIO units with 13 inch tube length. The bench provides three radiator mounting positions on the flat variant with support for up to 480mm radiators. Adding the optional second radiator tray extends the width from 385mm to 410mm, so confirm your workspace can accommodate the larger footprint.

Sustained Load Behaviour and Vibration Control

Anti-vibration pads are included for the PSU feet and radiator mounts to reduce resonance during extended test runs. The open design maintains unrestricted airflow around components, helping temperatures stay stable under continuous load. Rigid powdercoated steel construction prevents flex when heavy watercooling hardware is installed, keeping the platform steady during long benchmarking or stress-testing sessions.

Questions about this item

What hardware is included with the Praxis WetBenchSX Basic Flat Edition and what must be purchased separately?

The test bench ships with the powder-coated steel frame, motherboard tray, radiator brackets, anti-vibration pads for the PSU and radiators, and all mounting hardware. Every cooling component, pump, reservoir, tubing, power supply, motherboard, CPU and graphics card must be sourced separately.

Which radiator configuration does the Flat Edition support and how many positions are available?

The Flat Edition provides three radiator mounting positions and accepts radiators up to 480 mm in length. An optional second radiator tray extends the bench depth from 385 mm to 410 mm for additional mounting flexibility.

How much clear working space does the 338 mm by 385 mm footprint give when a full custom loop is installed?

The 338 mm length and 385 mm width keep the motherboard, up to three radiators, pump and reservoir within a compact open frame, so all fittings and tubing runs remain accessible without reaching over bulky case walls.
