Thermaltake UX400 ARGB White CPU cooler CL-P143-AL12SW-A

White single-tower air cooler for mainstream builds

The Thermaltake UX400 ARGB White uses four 6mm copper heat pipes in direct contact with the CPU to move heat into an aluminum fin stack rated for 240W TDP. A 120mm PWM fan pushes up to 62.72 CFM across the tower while the hydraulic bearing keeps noise at 25.0 dBA. The white finish and addressable RGB lighting suit builders who want a clean, illuminated aesthetic without a liquid loop. It is not for compact cases that cannot clear a 120mm fan height or for overclockers chasing loads beyond the rated dissipation.

Sustained-load thermal behaviour

Under continuous load the fan ramps between 700 and 1800 RPM to match the heat output, maintaining airflow without sudden speed spikes. The hydraulic bearing reduces friction during long runs, helping the cooler hold steady temperatures during extended rendering or gaming sessions. The single-tower layout relies on case airflow to exhaust the heated air, so a well-ventilated chassis is required for consistent results. It is not for fanless or semi-passive builds that depend on convection alone.

Build quality and everyday mounting

The cooler weighs more than 450g, giving a solid feel without stressing the motherboard socket. Its non-interference design leaves the memory slots completely open, so tall DIMM kits install without clearance checks. Mounting hardware covers Intel LGA 1851, 1700, 1200, 1156, 1155, 1151, 1150 and AMD AM5, AM4, FM2, FM1, AM3+, AM3, AM2+, AM2. Power connects through a 5V ARGB header and a standard 4-pin PWM plug. It is not for platforms outside the listed sockets or for systems lacking a 5V ARGB header to drive the lighting.
