Z370 chipset for 8th Gen Intel Core

This ATX motherboard uses the Intel Z370 chipset and the LGA 1151 socket limited to 300 Series processors. It accepts 8th Generation Core i7, i5 and i3 CPUs only and will not work with earlier LGA 1151 chips. Four 288pin DDR4 slots support up to 64GB in dual channel mode. The board targets builders who want a mainstream platform with overclocking headroom for 8th Gen CPUs.

Sustained load with Smart Fan 5 cooling

The VRM area and chipset are managed by Smart Fan 5 headers that adjust speed based on multiple onboard temperature sensors. Under prolonged heavy CPU or memory loads the fan curves ramp gradually to keep component temperatures stable without sudden noise spikes. Six SATA 6Gb/s ports and one M.2 Socket 3 M key connector handle storage traffic continuously at rated speeds. The Intel GbE LAN chip maintains 1Gbps throughput during long transfers.

ATX layout with standard mounting and clear I/O

The board follows the ATX form factor with standard screw holes that align with common chassis standoffs. Back I/O includes HDMI, DVI-D, PS/2 combo, two USB 2.0/1.1 and four USB 3.1 Gen 2 Type-A ports. Installers sometimes forget that the DVI-D port does not accept a D-Sub adapter, so a native DVI-D or HDMI display cable is required. The single full-length PCI Express 3.0 x16 slot and two x4 slots leave enough room for dual-slot graphics cards when populated correctly.

Questions about this item

How does the Smart Fan 5 Cooling on the Z370 HD3 handle heat during all-day loads?

Smart Fan 5 Cooling uses multiple temperature headers and hybrid fan pins to adjust speeds automatically, keeping the Intel Z370 chipset and VRM area cool under sustained 8th Gen Core workloads

Which CPU and memory must I already have for this LGA 1151 (300 Series) board to post?

You need an 8th Generation Intel Core i7, i5 or i3 processor in the LGA1151 package plus DDR4 modules — 288-pin, up to 64 GB across four slots, running at 2133 to 4000 MT/s (OC)

Can I keep my existing SATA SSDs and PCIe 3.0 add-in cards when moving to this Z370 HD3?

Yes — six SATA 6Gb/s ports support current SSDs and HDDs, while one PCIe 3.0 x16 slot and three PCIe 3.0 x1 slots accept existing graphics, sound or networking cards
