I recently upgraded my PC and ran Cinebench R23 to test my Ryzen 7 9800X3D, but I'm worried about the temperatures I'm seeing. Right from the start of the benchmark, my CPU temperature jumps to over 90°C and stays there through the entire test. I've attached a screenshot showing my results: the left side is with stock BIOS settings, and the right side has EXPO 1 enabled for the memory. Is this typical for this CPU with a standard air cooler, or should I be concerned about these temperatures? Here are my system specs:
- CPU: AMD Ryzen 7 9800X3D
- Motherboard: ASUS TUF GAMING B850M-PLUS WIFI (BIOS v0327)
- RAM: Kingston FURY Beast RGB EXPO DDR5 2x16GB
- Cooler: ID-COOLING FROZN A620 PRO SE ARGB
- GPU: NVIDIA GeForce RTX 5080
I've included a screenshot for reference: [https://ibb.co/6zdYgcv](https://ibb.co/6zdYgcv)

Yeah, you’re definitely hitting the thermal limit. What do you expect from a synthetic benchmark designed to max out CPU performance right from the start? Also, when you mention a 'standard air cooler,' what does that mean for you? Is it at least a dual-tower design? That might help with better cooling performance than what you currently have.
Those temps are quite high! Even though Cinebench pushes the CPU under heavy loads, hitting the thermal junction max (Tjmax) means your CPU might be thermal throttling. Your cooler should ideally manage better temperatures than what you’re observing. What case do you have, and how many fans are installed? You might also want to consider re-mounting the cooler with fresh thermal paste; something might have gone awry during installation.
Remember that Ryzen 7000 and 9000 series CPUs are designed to reach thermal limits quickly under load. AMD considers that the standard operating temperature. Reviewers often pair these CPUs with massive coolers, and they still hit TjMax, so it's like a built-in feature.
I did list my cooler in the post, it's an air cooler but I guess I need to assess if it's adequate for this CPU.
