![z490 motherboard comparison](https://tech4gamers.com/wp-content/uploads/2020/12/Thermal-5.1-1024x647.jpg)
I was able to overclock the chip with all cores on 5.1GHz using 1.379V. For this, I have to set the Voltage Control Mode to Normal and use the override method with a -0.100 offset. The LLC was set to Auto. Under the Blender Benchmark, the average temperature was 72.25°C at an ambient of 18.5°C. The maximum power on the package was 172.339W. The system power draw was around 332W without the graphics load.
Thermal Imaging
We have used the Hti HT18 Thermal camera to record the thermals of the VRM area of the motherboard under load using blender benchmark on the stock and with an overclock scenario.
The maximum temperature on the MOSFETs was 49.7°C with an ambient of 19.5°C.
With 5.1GHz all core under Blender Benchmark testing, the maximum temperature on the MOSFETs was 62.4°C with an ambient of 18.5°C.
This shows the powerful cooling solution employed by AORUS on their Z490 PRO AX motherboard. I am expecting these values to be high with Intel i9 and more aggressive overclock, but given the result, these VRMs have enough cooling to handle any load.
