Question Odd issue with ASUS X570 ROG Crosshair Hero VIII and AMD Ryzen 9 3900X

[jon96789]

I originally purchased a MSi X570 MPG Gaming Pro Carbon Wi-Fi motherboard which sad to say had terrible VRM overheating issues which always caused the CPU to thermal throttle when the VRMs hit 95 degrees C whenever I encoded videos. The high temps were pretty normal on this motherboard. The CPU would occasionally hit 95 degrees with no issues.

I replaced the MSi with a ASUS X570 ROG Crosshair VIII Hero motherboard which I really like. With HWinFO64 running, the motherboard VRMs never exceeded 50 degrees C when encoding. But I noticed that whenever the CPU exceeds 90 degrees C, HWiNFO64 reports that the CPU thermal throttled.

I have a Corsair H115i RGB Platinum Pro and I know that the rad is mounted properly. The CPU idles at about 34 degrees C which seems to be pretty much what others have reported. When encoding videos, the CPU hits speeds of a steady 4.017 GHz on all cores. HWiBFO64 shows that the temps during encoding averages about 80 degrees C, but occasionally it will blip to 90 degrees for a split second or so (I have HWiNFO64 alert me when the CPU hits 90 degrees or when it thermal throttles).

Now the question is why would the CPU throttle at 90 degrees C on the ASUS when it never did with the MSi board even when exceeding 95 degrees C (it occasionally would blip to 98 degrees).

System Specs:
CPU: AMD Ryzen 9 3900X
Motherboard: ASUS X570 ROG Crosshair VIII Hero
GPU: MSi NVidia GeForce RTX2070 Gaming Z 8 GB RAM
Memory: 4x 8GB Corsair LPX Vengeance 3000 MHz DDR DIMMs
Hard Drive: 1TB Samsung 970 EVO Plus M.2 NVMe
CPU Cooler: Corsair H115i RGB Platinum Pro mounted on top
Case: Corsair 750D Full Tower with two intake fans in front and one exhaust fan on rear
Optical Drive: LG WH14NS40 Blu-Ray writer
Power Supply: Corsair CX850M

That BIOS is possibly pushing to high voltage even when it's not called for.
