Thermaltake UX400 ARGB specifications and in-depth review

Thermaltake UX400 ARGB

Manufacturer: Thermaltake

The Thermaltake UX400 ARGB is a single-fan air CPU cooler designed for desktop systems across a broad range of Intel platforms. It features ARGB lighting built into the fan assembly, adding a visual element without requiring a separate lighting kit. Thermal paste is included in the package, making it ready to install out of the box. The cooler carries a 2-year warranty and weighs 660 g.

On the technical side, the fan spins at up to 1800 RPM and moves a maximum of 62.72 CFM of air, with noise output ranging from 13 dB at its quietest to 25 dB at full speed. Fluid dynamic bearings support the fan mechanism. The heatsink measures 120 mm wide, 120 mm deep, and just 25 mm tall, reflecting a low-profile form factor. Compatible sockets include LGA 1851, LGA 1700, LGA 1200, LGA 1150, LGA 1151, and LGA 1155.

Pros
  • Fluid dynamic bearings support the fan mechanism, which tends to offer quieter and longer-lasting operation than simpler bearing types
  • Minimum noise output of 13 dB makes it relatively unobtrusive during light workloads
  • ARGB lighting is built in, adding visual customization without requiring a separate component
  • Thermal paste is included, allowing installation without sourcing additional materials
  • Covers six Intel LGA socket types, making it compatible with a wide range of Intel platforms
Cons
  • At just 25 mm in height, the heatsink's low-profile form factor may limit how much heat it can handle under demanding conditions
  • A single fan with a maximum airflow of 62.72 CFM provides a fixed thermal ceiling with no built-in option to expand cooling capacity
  • The 2-year warranty period is shorter than what some other coolers in this category offer
  • No built-in display for monitoring or status readout
Who is this for?

This cooler suits builders working with Intel-based systems across a broad range of LGA sockets, from older LGA 1155 platforms up to the newer LGA 1851, making it a practical choice for a variety of existing setups. Its low 25 mm heatsink height makes it particularly well-matched for compact or small-form-factor cases where taller coolers simply will not fit. Users who prioritize a quieter working environment during everyday tasks will also appreciate the 13 dB minimum noise floor, which keeps the cooler unobtrusive under lighter loads.

Who is this NOT for?

Users running thermally demanding workloads such as sustained rendering, heavy simulation, or overclocking will likely find the single-fan setup and 25 mm heatsink height insufficient for maintaining comfortable temperatures over extended periods. The cooler is also not suitable for anyone needing AMD socket compatibility, as the listed socket support covers only Intel LGA platforms. Those who require a built-in display for real-time monitoring or status readout will need to look elsewhere, as no such feature is present on this unit.

Cooling:

Cooling type Air
Max fan RPM 1800 rpm
Max airflow 62.72 CFM
Number of fans 1

This cooler uses an air cooling approach, relying on a single fan to move heat away from the processor. That fan reaches a maximum speed of 1800 RPM and is capable of delivering up to 62.72 CFM of airflow at its peak, providing a defined ceiling for thermal dissipation under load.

Dimensions:

Heatsink/water block height 25 mm
Heatsink/water block width 120 mm
Heatsink/water block depth 120 mm

The heatsink measures 120 mm in both width and depth, giving it a square footprint that aligns with standard 120 mm fan mounting. Its height of just 25 mm makes it a notably low-profile unit, which may be a relevant consideration depending on the clearance available inside a given chassis.

General info:

CPU socket LGA 1851, LGA 1700, LGA 1200, LGA 1150, LGA 1151, LGA 1155
Audible noise (min) 13 dB
Audible noise (max) 25 dB
weight 660 g
warranty period 2 years

The UX400 ARGB is compatible with a range of Intel sockets, covering LGA 1851, LGA 1700, LGA 1200, LGA 1150, LGA 1151, and LGA 1155. Audible noise falls between 13 dB at its quietest and 25 dB at maximum speed, keeping the operational range relatively contained. The unit weighs 660 g and is backed by a 2-year warranty.

Features:

Fan bearings Fluid dynamic bearings
has RGB lighting ✓
Thermal paste Included
Has a display ✕

The fan uses fluid dynamic bearings, which is the bearing type employed in the fan mechanism. RGB lighting is present on this cooler, adding a visual element to the build. Thermal paste comes included in the package, so no separate purchase is needed before installation. The cooler does not feature a built-in display.

Final Verdict

The Thermaltake UX400 ARGB occupies a clear niche as a low-profile air cooler built around broad Intel socket support and quiet everyday operation. Its 25 mm heatsink height defines both its main strength and its ceiling — making it a genuinely practical fit for space-constrained builds while naturally limiting its headroom under sustained thermal load. The inclusion of ARGB lighting and thermal paste adds convenience without complicating the package. For users building compact Intel systems who prioritize a quiet, tidy setup over maximum cooling capacity, the UX400 ARGB delivers a coherent and well-defined set of specifications that match its intended use case.
