Keep thermals in spec with exact-match fans and heatsinks for the major server platforms.

A failed fan is one of the cheapest server repairs — and one of the most urgent, because platforms respond to a lost fan by spinning the rest to full speed (loud, power-hungry) and, if thermals keep climbing, throttling or shutting down. Monitoring flags failed and predicted-failure fans long before damage; the fix is a slide-in module on most modern platforms.
Heatsinks matter when adding a second processor: the CPU kit needs the platform's matching heatsink (and often a specific shroud), which OEMs sell separately and part searches routinely miss. We stock hot-swap fan modules, full fan assemblies, and CPU heatsinks per platform — identified, as always, by the part number on the failed unit or your server's service tag.
On most enterprise platforms yes — chassis fans are hot-swap modules designed for replacement with the system running. Check your platform’s service manual; we will confirm when you order.
Usually a failed or failing fan: the platform compensates by running remaining fans at high speed. Replacing the flagged module returns noise and power draw to normal.
Yes — heatsinks are platform-specific and sometimes differ by TDP tier within a platform. Tell us your server model and target CPU and we will supply the correct kit.
