ARCTIC Freezer 4U-M Ampere 4U Server CPU Air Cooler (ACFRE00171A)

Purpose-Built Air Cooling for a Compatible Server or Workstation

The ARCTIC Freezer 4U-M Ampere is a server CPU air cooler for a carefully matched professional platform, not a conventional consumer gaming cooler. Its two fans move air through a substantial fin stack in push-pull, making it relevant to compatible workstation and server projects with a planned chassis airflow path.

The 145 mm height and listed server-socket support provide a useful starting point for fit planning, while the stated memory clearance helps with the surrounding component layout. A 4U designation does not guarantee every chassis or motherboard fits: verify the exact socket, mounting arrangement, RAM height and enclosure clearance before ordering.

Best For: Compatible server builds, Ampere Altra systems, Professional workstations, 4U chassis projects, Server cooler replacements, System-integrator projects

DETAIL SPECIFICATION

TECHNICAL FEATURES

A server-specific compatibility list

This cooler addresses the listed server platforms. Match the exact motherboard socket and processor installation instructions; do not substitute a consumer-platform mounting assumption.

Two fans across the heatsink

The push-pull arrangement is intended to move air through the fin stack. Coordinate the cooler direction with the chassis intake and exhaust, particularly in a densely populated system.

PWM control for a managed system

A compatible controller can regulate the fan speed with cooling demand. Configuration remains important: a speed range is not a guaranteed system-noise or processor-temperature result.

Plan RAM and chassis clearance together

Check more than the rack-unit label. The memory modules, surrounding components, mounting space and case cover all need to accommodate the exact assembly.

🔎 Technical Conclusion

Cooler Layout:
A substantial two-fan air-cooling assembly for a planned server or workstation airflow path.

Server Socket Support:
Appropriate only when the exact platform appears in the verified compatibility list and uses the correct mounting method.

Memory Clearance:
The specified clearance is a planning aid, not a replacement for checking the real memory modules and surrounding board layout.

Fan Control:
PWM operation allows compatible system control; cooling and acoustic behaviour depend on the complete installation.

Chassis Planning:
Confirm enclosure height and component clearances even when the project uses a nominally 4U chassis.

Overall Positioning:
A specialist server-cooling choice for compatible professional systems, rather than an interchangeable cooler for every desktop PC.

✅ Suitable For

• Ampere Altra system builders
  The listed Ampere socket makes this exact variant relevant to an appropriately matched Altra platform after mounting and chassis checks.
• Compatible Intel server projects
  Consider it only for a listed supported server socket, with the mounting instructions and surrounding components checked before fitting.
• Compatible AMD workstation or server platforms
  The verified server/workstation socket list supports several build types, but does not imply consumer AM4 or AM5 compatibility.
• Professional system integrators
  A planned server-cooler replacement can use the dimensional and clearance data to evaluate a complete system rather than buying by appearance alone.
