Ruth's sister Internal Power Cable 9XJXY FKG1H Heatsink Fan Assembly 5-Pin LGA1155

SKU CH-HMHK-DK787

Cools compatible Dell OptiPlex and Precision desktops with a 5-pin LGA1155 heatsink and fan assembly

  • Cools compatible Dell OptiPlex and Precision desktops
  • 5-pin 4-wire connector fits LGA1155 socket
  • Small heatsink design suits desktop form factor
  • Replaces Dell part numbers D0W1H and 9XJXY
  • Includes heatsink and fan assembly only

Direct replacement for OptiPlex

This CPU heatsink and fan assembly fits Dell OptiPlex 790, 990, 7010, 9010 and 3020 mini-tower models plus Precision T1600, T1650 and T1700 workstations. It mounts on the LGA1155 socket and uses the original 5-pin, 4-wire connector so the motherboard controls fan speed automatically. No extra brackets or adapters are required for installation.

Compact heatsink with factory 5-pin connector

The unit is a small-form-factor heatsink designed for desktop chassis where clearance is limited. Its 5-pin, 4-wire plug delivers both power and PWM signalling through a single connection, keeping cable routing simple and preserving the system's thermal management. The assembly arrives as a complete cooler with no additional parts in the box.

Swaps out noisy or failed stock coolers

Replacing a worn or loud original cooler restores quiet operation and reliable temperatures for LGA1155 processors in the listed OptiPlex and Precision systems. The upgrade is worthwhile when the existing fan rattles, overheats or no longer spins at controlled speeds. Builders needing a different socket, a larger radiator or a non-proprietary mounting pattern should look elsewhere.
