1U Passive Cooler for LGA 1156

The ASRock Rack 1U PASSIVE 1156 COOL is a passive server cooler designed for LGA 1156 socket processors. It fits 1U rackmount chassis where active fan cooling is not preferred. System builders targeting silent or dust-resistant deployments will find this cooler suitable for compatible ASRock Rack motherboards.

Compatibility Check Before Ordering

Verify that your motherboard uses the LGA 1156 socket and that the CPU thermal design power falls within passive cooling limits. Confirm the board layout matches the ASRock Rack X570D4I-2T reference design, as mounting hole alignment is specific to that platform. Ensure the 1U chassis provides adequate airflow across the heatsink fins without a dedicated fan.

Build Integration and Airflow

This cooler mounts directly to the CPU retention mechanism using the supplied hardware, requiring no additional brackets or backplates. Its low-profile design leaves full clearance for DIMM slots and PCIe riser cards in dense 1U layouts. Passive operation eliminates a moving part, reducing maintenance cycles and freeing the single chassis fan slot for system-level airflow instead of CPU cooling.

Questions about this item

Does the 1U PASSIVE 1156 COOLER include mounting hardware for the AM4 PGA 1331 socket, or must a separate bracket be purchased?

The cooler is designed for the AM4 PGA 1331 socket and ships with the necessary mounting hardware; no separate bracket is required for installation on supported ASRock Rack boards.

Which ASRock Rack motherboard is the 1U PASSIVE 1156 COOLER validated for, the X570D4I-2T or other models?

The manufacturer highlights list support for the ASRock Rack X570D4I-2T; compatibility with other boards is not confirmed by the supplied data.

How does the passive 1U design affect thermal performance when installed in a 1U chassis with the X570D4I-2T?

The passive cooler relies on chassis airflow to dissipate heat; in a 1U enclosure with directed airflow it maintains the CPU within its thermal limits for supported workloads.
