ID-Cooling SE-903-XT

Manufacturer: ID-Cooling

The ID-Cooling SE-903-XT is a single-fan air CPU cooler designed to fit a wide range of current and recent Intel and AMD platforms, including LGA 1851, LGA 1700, AM4, and AM5 among others. It weighs 350g, ships with thermal paste included, and carries a three-year warranty, making it a straightforward option for builds that need broad socket support without additional thermal compound purchases.

The cooler measures 123mm tall, 65mm wide, and 100mm deep, with its single fan spinning up to 2200 RPM and delivering a maximum airflow of 45.8 CFM. Noise output ranges from 16 dB at its quietest to 25.8 dB at full speed. The fan runs on fluid dynamic bearings for smoother and quieter long-term operation, and RGB lighting is included for builds where aesthetics matter. There is no integrated display on the unit.

Pros
  • Compatible with a wide range of Intel and AMD sockets, including LGA 1851, LGA 1700, AM4, and AM5, making it usable across many current and recent platforms
  • Noise output tops out at 25.8 dB at full speed, with a low floor of 16 dB, keeping the fan audibly unobtrusive during typical use
  • Fluid dynamic bearings support quieter and longer-lasting fan operation compared to sleeve bearing designs
  • Thermal paste is included in the box, allowing installation without sourcing additional materials
  • Backed by a 3-year warranty, providing a reasonable coverage period for a cooling component
Cons
  • A single fan with a maximum airflow of 45.8 CFM may be insufficient for high thermal load scenarios
  • The heatsink is 123 mm tall, which could be a fitment concern in smaller or compact cases with limited CPU cooler clearance
  • At 65 mm wide, the heatsink footprint is narrow, which may limit the surface area available for heat dissipation
  • There is no display on the unit, so real-time fan speed or temperature readouts are not available directly from the cooler
Who is this for?

The SE-903-XT suits builders putting together mainstream desktop systems across a variety of Intel and AMD platforms, given its broad socket compatibility spanning LGA 1851 through to AM5. Its noise range of 16 to 25.8 dB makes it a reasonable fit for users who are sensitive to fan noise and want an unobtrusive cooler for everyday computing, office workloads, or light content creation tasks. The inclusion of thermal paste and a 3-year warranty also makes it a practical option for those who want a complete, low-fuss installation without sourcing additional components.

Who is this NOT for?

Users building systems around processors with high thermal output will likely find the single-fan setup and 45.8 CFM maximum airflow insufficient to maintain stable temperatures under sustained heavy loads such as overclocking, intensive rendering, or long gaming sessions. Those working with compact or small-form-factor cases may also encounter clearance issues given the 123 mm heatsink height, which can conflict with tighter chassis designs. Additionally, builders who want real-time thermal or fan data at a glance will not find that here, as there is no integrated display on the unit.

Cooling:

Cooling type Air
Max fan RPM 2200 rpm
Max airflow 45.8 CFM
Number of fans 1

The SE-903-XT uses air cooling with a single fan that spins up to 2200 RPM and moves a maximum of 45.8 CFM of airflow, covering the core cooling requirements through direct heatsink-and-fan dissipation.

Dimensions:

Heatsink/water block height 123 mm
Heatsink/water block width 65 mm
Heatsink/water block depth 100 mm

The heatsink on the SE-903-XT measures 123 mm in height, 65 mm in width, and 100 mm in depth, giving a relatively compact footprint that should suit cases with standard CPU cooler clearance.

General info:

CPU socket LGA 1851, LGA 1700, LGA 1200, LGA 1151, LGA 1155, LGA 1150, AM4, AM5
Audible noise (min) 16 dB
Audible noise (max) 25.8 dB
weight 350 g
warranty period 3 years

The SE-903-XT is compatible with a broad range of CPU sockets, covering Intel's LGA 1851, LGA 1700, LGA 1200, LGA 1151, LGA 1155, and LGA 1150, as well as AMD's AM4 and AM5 platforms. Audible noise ranges from 16 dB at its lowest to 25.8 dB at full fan speed, keeping operation relatively quiet under most conditions. The unit weighs 350g and is backed by a 3-year warranty.

Features:

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

The fan runs on fluid dynamic bearings, which generally contribute to quieter and smoother operation over time. RGB lighting is built in for builds where visual customisation is a consideration, and thermal paste comes included in the box, removing the need for a separate purchase before installation. There is no integrated display on the unit.

Final Verdict

The ID-Cooling SE-903-XT is a straightforward air CPU cooler that delivers where it matters most for mainstream builds: broad socket compatibility across both Intel and AMD platforms, a quiet operational noise ceiling of 25.8 dB, fluid dynamic bearings, and a complete out-of-box experience with thermal paste and a three-year warranty included. Its single-fan configuration and compact heatsink dimensions do place a natural ceiling on how much heat it can reliably manage, so users with thermally demanding workloads or overclocking ambitions should factor that in. For builders seeking a no-fuss, quiet, and widely compatible air cooler for everyday desktop use, the SE-903-XT covers the essentials capably and with enough platform versatility to serve across multiple builds.
