Dell PowerEdge 1U HeatsinkR630 CPU Cooling | H1M29

The Dell H1M29 (also cataloged as 0H1M29) is the factory-standard passive CPU heatsink designed specifically for the Dell PowerEdge R630 1U rackmount server. It serves as a vital component of the server's dense chassis cooling infrastructure

• Server Generation Compatibility: Exclusively tailored for the Dell PowerEdge R630. It mounts securely onto the server's LGA2011-3 processor sockets.
• : Formally rated to handle thermal profiles >strong class="Yjhzub" data-sfc-root="c" data-sfc-cb="" data-complete="true" data-copy-service-computed-style="font-family: Google Sans, Arial, sans-serif; font-size: 16px; font-weight: 600; margin: 0px; text-decoration: none; border-bottom: 0px rgb(10, 10, 10);">up to 120 Watts.
• Cooling Method: Completely passive design. It relies entirely on the high-velocity directional airflow forced through the 1U chassis by the server's modular fan array. [1, 2, 3, 4, 5]

System Integration Guidelines

• Processor Matching: This model is optimized for mid-range Intel Xeon E5-2600 v3 and v4 processors that operate at or below a 120W TDP (e.g., Xeon E5-2650 v4 or E5-2630 v4).
• High-TDP Warning: If you intend to run premium, high-core processors exceeding 120W—such as 135W or 145W variants (e.g., Intel Xeon E5-2697 v4 or E5-2699 v4)—this standard cooler cannot dissipate the heat fast enough. For those configurations, Dell requires the alternative High-Performance Heatsink variant (often associated with part numbers like 0Y8MC1) to prevent CPU thermal throttling or emergency shutdowns.
• Installation Best Practices: When installing or transferring this unit, clean old thermal interface material completely using isopropyl alcohol, and apply a fresh layer of high-grade thermal paste evenly across the CPU integrated heat spreader (IHS) before tightening the integrated retention screws in a diagonal pattern.
