LGA 1200 Micro ATX board for 10

This Micro ATX motherboard uses the Intel B560 chipset and an LGA 1200 socket to support 10th and 11th Gen Intel Core processors plus Pentium Gold and Celeron CPUs. Four DDR4 slots accept up to 128GB of memory with a long list of overclocked speeds. The board fits compact cases while still providing two full-length PCIe x16 slots and six SATA 6Gb/s ports.

Extended heatsink M.2 Shield FROZR and 2.5G LAN

An extended PWM heatsink covers the power delivery for sustained loads. The M.2 Shield FROZR acts as a thermal accessory for installed M.2 drives to limit throttling. A Realtek RTL8125B controller provides a 2.5Gbps LAN port with LAN manager software. Audio Boost circuitry delivers 7.1 channel output and the rear I/O includes a USB 3.2 Gen 2x2 Type-C port rated at 20Gbps. Frozr AI Cooling monitors CPU and GPU temperatures to adjust fan duty automatically.

PCIe 4.0 from CPU for 11 Gen or PCIe 3.0 for 10 Gen

The primary PCIe x16 slot and the first M.2 slot run at PCIe 4.0 x4 when an 11th Gen processor is installed and fall back to PCIe 3.0 with a 10th Gen CPU. The second PCIe x16 slot and the second M.2 slot are wired to the chipset at PCIe 3.0. This split determines the maximum bandwidth available to graphics cards and high-speed storage.

Questions about this item

How often should I clean the extended PWM heatsink and M.2 Shield FROZR to maintain cooling performance?

Clean the extended PWM heatsink and M.2 Shield FROZR every 6 to 12 months using compressed air to remove dust buildup that can reduce thermal efficiency.

Which component hits its limit first during sustained heavy loads on this board?

The VRM area cooled by the extended PWM heatsink is the first to reach thermal limits under continuous high-current operation with multi-core 11th Gen CPUs.

How loud and hot does the board get when running all day with the Frozr AI Cooling active?

Frozr AI Cooling automatically adjusts fan duty based on CPU and GPU temperatures, keeping VRM and M.2 thermals in check while minimising acoustic output during extended sessions.
