Max Operating Temperature (Blender)
To check the operating temperatures, I run Blender instead of Prime95 and small FFTs, which apply an unrealistically high load to the CPU.
The max operating temperature is set at 95°C, but as shown in the graph above, I was way below that with a good air cooler. The improved heat spreader and the lower thermal resistance between it and the CPU’s die led to these results. So even with a high-end cooler and not an AIO, as AMD suggests, you can keep the 9900x at low enough temperatures under full load.

How? I’ve got a 9900x and playing high end games throttles with a Thermalright Peerless Assassin. I’m going to have to water cool this thing just to be able to game lol.
A Peerless Assassin would not be able to hold the 9900X cool in a high usage environment, the real solution really is a heftier cooler, got myself a MSI Mag Coreliquid A13 and the highest temperature my 9900X got while editing was only 80C.
