Re: RYZEN 9 5900X Overheats?!

I have the same specs. My CPU did hit the maximum 90 degrees. I don’t know how to fix it.. :(

Re: RYZEN 9 5900X Overheats?!

If you're hitting 80C+ with PBO disabled and high-end air or AIO cooling, that isn't normal. If PBO is enabled and caps set to "motherboard" it's totally normal though.

AMD says Zen3 can handle 90C all day long no problem, but I'm not comfortable with that either, so I set my PBO caps manually to 162w PPT, 115A TDC, 160A EDC which has me hitting around 77C at full load. The actual numbers you want depend on the temperature you're comfortable running and your cooling. I'm on high-end air (NH-D15) but if you've got a 360mm AIO or whatever you can certainly go higher.

Same here, didn't have that problem with 5600x i think I'm returning the 5900x unfortunately. It's giving me headache trying to figure out why it just spikes randomly for no reason on desktop.

NZXT CAM just sux with AMD system

You should try "FanControl" to set the maximum fan speed to the best noise/cooling ratio.

Re: RYZEN 9 5900X Overheats?!

What motherboard, bios, voltages, and cooler are you running? I am using an almost 3 year old H100i in quiet mode with PBO and voltage set to mother board maximum on an x570 taichi. I am regularly boosting to 5.16 on light workloads and 4.49 all core on cinebench with temps hovering around 77 after multiple passes. On 3dmark with an overclocked reference 6900xt dumping loads of hot air into an o11-d XL cpu temps never really go above 70 on the cpu

Don’t worry. Your temperatures are normal.

Re: RYZEN 9 5900X Overheats?!

Just installed a new combo with 5900x.

My temps are 35-40 idle, depending on time. At start 35, but when the liquid heats a bit, 40. Stress testing the CPU, I don’t go past 65-67.
