Plus, you will find additional AORUS brandings on the chipset. 

Beneath the chipset heatsink, you will find the only RGB LED lights that offer a vibrant glow. It has saturated colours along the base, but if the illumination is not enough, you can increase its vibrancy. Do this by using the onboard headers and adjusting the brightness based on your preferences. 

For its power design, the motherboard sports a 12+1+1 phase power design consisting of the NCP-302155. It also sports the NTMF-4C06N and NTMFS-4C10N MOSFETs from onsemi. 

The primary phase sports the NCP-302155, which can accommodate 60A each. Then the remaining ones for the built-in GPU can accommodate 50A each.

GIGABYTE B660M AORUS PRO AX Motherboard Thermal Output

This motherboard sports a set of heatsinks for its VRMs, board chipset, and M2 SSD to handle its thermal output. And compared to high-end Z690 boards featuring aluminium fins array heatsinks, this board uses an aluminium block type. These heatsinks are usually present on boards under the same category.

They are simple but can get the job done, so we do not have any complaints.

For its onboard audio solution, the motherboard uses the Realtek ALC-897 codec. It also has Nichicon audio capacitors to deliver performance.

The company did not use PCIe 5.0 support on their B660 motherboards. The highest support is PCIe 4.0 from the CPU, which settles on the first PCIe x16 slot. 

The other PCIe x16 slot is from another chipset operating under PCIe 3.0 x4.

Its rear IO is reasonable, especially with its number of ports available. But aside from the number of USB ports, the motherboard also features basic audio jacks plus SPDIF support. The product even has WiFi 6 with Bluetooth 5.2 and 2.5GbE LAN for connections.

Except for the lack of processor overclocking functionality, the motherboard firmware appears similar to those on more expensive Z690 boards. The BIOS starts in an informational EZ Mode with functions that display system information. 

You can enable XMP profiles, access Smart Fan 6 fan controls, update the BIOS with Q-Flash, or enter Advanced Mode.

In BIOS, primary headers are across the top of the advanced section. There is a new page up/down functionality, and the BIOS is simpler to understand. With its well-organised interface, it is easier to find what you need.

The primary tool of Gigabyte in terms of software is the App Centre. It is a centre for motherboard apps, several Windows settings, and other third-party software.

Click to download the desired applications, install them, and an icon will appear on the screen. BIOS, Easy Tune, RGB Fusion 2.0, and SIV were all installed. Other useful programmes on the Gigabyte website include USB charging, LAN, and others not included here.

Overall, we enjoy the tiny size of App Center and found its modular tools to be helpful.

The B660M AORUS PRO AX performed admirably in single and weekly threaded synthetics. Due to thermal throttling from the default settings, the board struggled. If necessary, a negative voltage offset can work to prevent throttling.

There are no concerns because gaming performance was consistent with the other outcomes. It all comes down to how you use your system and whether you are prepared to make changes when necessary.
