Processor identity and audience

The Intel Core i5-7400T is a 7th Generation quad-core desktop CPU built on a 14nm Kaby Lake architecture. It operates at a 2.4 GHz base frequency with a 3.0 GHz maximum turbo and carries 6MB of L3 cache. The boxed processor fits the LGA 1151 socket and includes Intel HD Graphics 630 for integrated display output.

Suitability guidance

This chip suits small-form-factor builds or upgrades where a 35 W thermal envelope simplifies cooling and power delivery. It supports dual-channel DDR4-2133 and DDR4-2400 as well as DDR3L-1333 and DDR3L-1600 at 1.35V, so existing memory can often be reused. Systems that need Hyper-Threading, higher base clocks or unlocked multipliers should look at other models.

Deciding specification

The defining figure is the 35 W TDP combined with the 2.4 GHz base clock, which determines whether the processor fits the thermal and performance budget of a compact or fanless chassis. Verify the motherboard BIOS supports 7th Generation Kaby Lake CPUs before purchase.

Questions about this item

Will the LGA 1151 socket on my motherboard accept the Core i5-7400T?

Yes, the processor uses the LGA 1151 socket; ensure the motherboard chipset supports 7th Generation Intel Core desktop CPUs and has a compatible BIOS revision.

Does the boxed cooler mount directly to the standard LGA 1151 holes, or do I need a separate bracket?

The boxed cooler uses the standard LGA 1151 mounting pattern; align the four push-pins with the motherboard holes, press each diagonally until it clicks, and verify the fan header is connected before powering on.

If the thermal paste on the included cooler dries out, what replacement paste spec should I use?

Use a non-conductive ceramic or carbon-based paste rated for CPUs up to 35 W TDP; apply a pea-sized dot, remount the cooler with even pressure, and reconnect the fan header.
