Heatsink for Dell PowerEdge R640, C4140 is a replacement CPU heatsink for Dell PowerEdge R640, C4140. Unlike desktop PCs, rack and tower servers rely on ducted, front-to-back airflow engineered by the OEM for that exact chassis — the heatsink's fin design, height, and mounting pattern are matched to the server's own fan/duct layout, not a generic aftermarket cooler. Using the correct OEM-spec heatsink is what keeps CPU temperatures in spec under sustained server load.
Why the Correct Heatsink Matters
A mismatched or worn heatsink is a common cause of CPU thermal throttling, unexpected shutdowns, or the server's BIOS/iLO/iDRAC reporting a thermal fault — even when the rest of the system is healthy. This heatsink is specified for Dell PowerEdge R640, C4140, so it bolts directly onto the existing mounting bracket with no modification.
Condition & Testing
Sourced from decommissioned enterprise hardware, cleaned, and inspected for warped or damaged fins before listing. Every unit ships ready to install — apply fresh thermal paste (not included) during fitting for best contact.
