Intel Core i5-10400 OEM Processor

The Intel Core i5-10400 is a 10th Generation Comet Lake desktop CPU with six cores and twelve threads. It operates at a base frequency of 2.9 GHz and can turbo boost up to 4.30 GHz within a 65W thermal envelope. The processor includes Intel UHD Graphics 630 and 12 MB of L3 cache for integrated graphics capability and responsive multitasking.

LGA 1200 Socket and Cooling Requirement

This OEM processor requires a motherboard with an LGA 1200 socket and a chipset supporting 10th Generation Intel Core processors. No cooling device is included in the package so a compatible CPU cooler must be sourced separately. Verify that your chosen cooler supports the LGA 1200 mounting pattern and can handle a 65W TDP before installation.

OEM Packaging Implications

The product ships as a processor only without a retail box or stock cooler. This means no bundled thermal solution or printed documentation is provided. Buyers should prepare to download drivers and installation guides directly from Intel support channels and ensure adequate thermal paste is available for the chosen aftermarket cooler.

Questions about this item

Does the i5-10400 OEM package include a cooler or must I buy one separately?

The OEM tray contains only the processor; a compatible LGA 1200 cooler is not supplied and must be purchased separately.

Should I choose the 6-core 2.9 GHz model or a higher-clocked variant for my build?

This specific SKU is the 6-core 2.9 GHz base with 4.30 GHz turbo; no other clock or core-count versions are offered under this part number.

What does the 4.30 GHz turbo figure mean when the chip is inside a working PC?

The 4.30 GHz turbo is the maximum single-core frequency the CPU can reach under load, limited by the 65 W power envelope and your cooling solution.
