5900x problem?

Selix · May 17, 2021

Hey everyone,

So I used to have a 3700x but I managed to get a 5900x and I installed it in my system. I'm not sure if I did something wrong though because I'm not really matching what I see from other people. It idles at 2.2 ghz and boosts to 4.1, but I thought it was supposed to go to 4.8? It also idles at 50 C and when I put it under full load it goes to 77C. It also gets a score of 7331 on cinebench r20 which seems lower than it should be? I run my pc on quieter modes but it doesn't normally sacrifice that much performance or run that hot before.

Some info for context, I don't generally run my fans that high since I prefer a quiet pc over a bit of performance. The cooler is the bequiet dark rock 4 (non pro), and the case is a fractal meshify c. I have two noctua fans in front and included fan at top and back. This wasn't an issue with my 3700x, but I'm worried I did something for the 5900x. Maybe some leftover bios or software settings from before are making it act weirdly? Or maybe the cooler isn't good enough for this tier of cpu, or I'm just overreacting. If anyone can help, I'd really appreciate it, thank you!

Not normal. It should idle at 3.7Ghz and boost up to 4.8Ghz.

Temperatures likely seem fine because your CPU is throttling to keep the temperatures in check. I wouldn't recommend a traditional air cooler for anything more than 6 cores (even less if you want better sustained clock speeds). The 5900X has 12 cores, and you're running it on an older single-tower cooler.

Just get quieter fans, then you can run them as fast as you want if that's the issue. I don't understand why people would rather suffer from temperature issues like this than hear the sound of air moving.
