0A65721 C/D 30 Series Heatsink ensured efficient cooling and stable CPU performance in our ThinkStation systems.
Reliable thermal management component.
Improved system stability under load.
Solid build and effective heat dissipation.
Dependable heatsink for enterprise hardware.
Stable temperature control in production.
Reliable cooling solution.
The ThinkStation C/D 30 Series Heatsink is fully compatible with Lenovo ThinkStation C30 and D30 workstations.
It supports Intel LGA1155 socket processors, including Sandy Bridge and Ivy Bridge CPUs.
This heatsink is rated for up to 95W TDP to ensure effective heat dissipation under standard workloads.
It features a copper base and aluminum fins for optimal thermal conductivity and durability.
The heatsink measures 90 mm x 90 mm x 35 mm, designed to fit the 3U chassis of C30/D30 systems.
No, this part is the heatsink assembly only; the fan module is sold separately.
No, thermal interface material is not included and should be applied separately before installation.
Apply thermal paste, align the heatsink over the CPU socket, secure it with the retention bracket screws, and reconnect the fan power cable.
A standard Phillips screwdriver is required to secure the mounting screws during installation.
It is optimized for stock CPU speeds; significant overclocking may exceed its 95W thermal capacity.
Power off the system, remove dust with compressed air every three to six months, and gently clean the fin stack with a soft brush.
Noise depends on the chosen fan, but with the recommended 92 mm fan, you can expect around 25 dBA during full load.
No BIOS update is needed; it is compatible with the default firmware on C30/D30 workstations.
Yes, this is an OEM Lenovo replacement heatsink specifically designed for ThinkStation C/D 30 Series.
It is covered by Lenovo’s one-year limited parts warranty for replacement and repair.
No; it is engineered for ThinkStation C30/D30 chassis and may not be compatible with other systems.
You can buy it through the Lenovo official parts store or authorized Lenovo service partners.
