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

  • Cools compatible Dell OptiPlex and Precision desktops

  • Replaces Dell part numbers D0W1H and 9XJXY

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.

Questions about this item

What socket does the 5-pin LGA1155 heatsink fan assembly mount to?

It mounts directly to an LGA1155 socket on compatible Dell OptiPlex and Precision desktop boards.

Which Dell chassis and motherboard layouts does this heatsink fit?

It fits OptiPlex 790 MT, 790 DT, 990 MT, 7010 MT, 9010 MT, 3020 MT and Precision T1600, T1650, T1700 workstations.

How is the 5-pin fan connector installed, and what is the common mistake?

Plug the 5-pin connector into the motherboard CPU_FAN header; the mistake is leaving the latch unclicked, which causes the fan to run unmonitored.
