Who it fits
Good fit for
You should consider this cooler if you run a workstation or server in a 4U chassis. It fits systems using high-TDP Intel Xeon or AMD Threadripper Pro CPUs. The broad socket support covers many enterprise platforms. The 450W rating handles intense sustained workloads. If you need a reliable, rackmount-friendly solution for professional hardware, this unit provides the necessary cooling capacity and physical compatibility for your setup.
Who should skip it
Skip this option if you use a standard desktop ATX case. The 145mm height and 4U form factor do not fit typical consumer towers. It is also not for users needing RGB lighting or quiet operation below 44.9dBA. The fan speed can reach 3000rpm, which may be loud for office environments. If your chassis cannot accommodate 4U standards or your CPU TDP is under 250W, look for a more compact or quieter alternative.
Verdict: This cooler is a specialized tool for 4U workstation builds with high TDP requirements. It offers robust cooling and broad socket compatibility for enterprise hardware.
Key specs explained for you
TDP Rating 450W
This rating indicates the cooler can dissipate up to 450 watts of heat. You need this capacity for high-end workstation or server processors that generate significant thermal output. Standard desktop coolers often top out at 200W to 300W. This specification ensures your expensive CPU stays within safe operating temperatures under heavy, sustained workloads without overheating.
Cooler Height 145mm
The unit stands 145mm tall, which fits standard 4U rackmount chassis dimensions. You must verify your case has at least this much vertical clearance before purchasing. Taller coolers generally offer better heat dissipation due to larger surface areas. If your chassis is shorter, this cooler will not fit, regardless of its performance capabilities.
Heat Pipes 8
Eight 6mm heat pipes transfer heat from the base to the fins. More pipes typically mean faster heat spreading across the aluminum fin stack. This design helps move thermal energy away from the CPU socket quickly. When comparing air coolers, a higher pipe count often correlates with better thermal performance in high-TDP scenarios.
Fan Speed 3000rpm
The included fan can reach a maximum speed of 3000 RPM. This high speed pushes up to 102 CFM of air through the fins. You benefit from maximum airflow when the system is under peak load. Note that this speed also generates noise, reaching 44.9 dBA. You should check if your environment can tolerate this acoustic level.
Design and build details
The cooler uses eight six-millimeter heat pipes paired with aluminum fins. This configuration provides a large surface area for heat transfer. You get reliable thermal performance for high-wattage processors. The unit stands 145 millimeters tall. This height complies with standard 4U rackmount chassis dimensions. You can install it in industrial server racks without clearance issues. The overall footprint is 4.72 inches wide and long. The depth is 5.71 inches. These dimensions ensure it fits within typical workstation enclosures.
The fan is a 120 by 30 millimeter PWM model with dual ball bearings. It runs up to 3000 RPM. You get up to 102 CFM of airflow. The static pressure reaches 8.24 mmH2O. Noise levels stay at 44.9 dBA at maximum speed. A metal fan mounting bracket secures the fan. This bracket ensures stability during operation. You experience less vibration compared to plastic mounts. The finish is silver. This color matches standard server hardware aesthetics. The model number is SST-XED120S-WS. According to the listing, the cooler supports Intel LGA 4677 and 4710 sockets. It also works with AMD SP5, SP6, sTR5, SP3, TR4, sWRX8, and sWRX9. This wide compatibility makes it suitable for various workstation platforms.
Installation and daily operation
Setting up this cooler requires careful attention to your chassis dimensions. The unit stands 145 millimeters tall. You must verify that your 4U rackmount case has sufficient vertical clearance. The metal fan mounting bracket provides structural stability during installation. This design choice helps maintain alignment and reduces vibration. You should ensure the bracket is securely fastened to prevent movement.
Compatibility is broad for workstation environments. The cooler supports Intel LGA 4677 and LGA 4710 sockets. It also works with AMD SP5, SP6, sTR5, SP3, TR4, sWRX8, and sWRX9 sockets. This wide range makes it suitable for various server and high-end desktop platforms. You do not need to worry about socket mismatch if you are using standard workstation hardware.
Daily use involves managing fan noise and airflow. The included 120mm fan operates between 500 and 3000 RPM. At maximum speed, it moves 102 CFM of air. The noise level reaches 44.9 dBA at peak performance. You will likely run the fan at lower speeds for routine tasks. The dual ball bearing design suggests long-term reliability. You can expect consistent performance without frequent maintenance. The PWM control allows your motherboard to adjust speed based on load. This ensures efficient cooling while keeping noise manageable during light workloads.
Before You Buy This Cooler
You need to verify your server or workstation chassis supports the 145-millimeter height before purchasing. This cooler is built for 4U rackmount standards, so standard desktop cases will not work. Check your CPU socket compatibility carefully. It supports Intel LGA 4677, LGA 4710, and AMD SP5, SP6, sTR5, SP3, TR4, and sWRX9. Ensure your motherboard is present in this list. You must also confirm your power supply provides the necessary PWM headers for the included fan. The dual ball bearing fan requires regular dust cleaning to maintain its 102 CFM airflow and keep noise levels near 44.9 dBA. This unit belongs in the high-end category for workstation builds. It sits alongside other industrial-grade coolers that prioritize stability and thermal capacity over compact size. You should compare its 450W TDP rating with your processor’s actual heat output. If your system runs below 300W, this cooler may be overkill. For high-density computing, it offers robust heat dissipation through its eight six-millimeter heat pipes and aluminum fin stack. Always measure your available space precisely to avoid installation conflicts.
Check before you buy
- Verify your chassis is a 4U rackmount type with 145mm clearance.
- Check if your CPU socket is supported by the cooler.
- Confirm your motherboard has a PWM fan header available.
- Ensure your processor TDP does not exceed 450W.
