Question Undervolting my 5800X

[Daniel Youssef]

I have a problem with my chip basically, benchmarks or stress tests makes my 5800X reach 90°C constant as long as it is under load, even going to usage like 60% in cpu demanding games may make it reach that temperature in summer

I have just bought an Arctic Freezer 3 AIO 2 days ago and nothing has changed, i think my only solution is to undervolt

My Motherboard is Asus rog strix b550-F gaming, when I set Asus optimize mode, it ran on 4.2ghz constant with 75 max temperature and ofc lower voltage I think, so using PBO can I achieve undervolt without sacrificing gaming performance? I have no clue which values to mess with so I would like some help

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

You might want to address the thermal solution in your build. Arctic has a couple of Liquid Freezer III's in their portfolio, which one do you have and how is it mounted in your build?

Once we've figured out that your AIO is setup the right way, then you can look into undervolting. If your cooling isn't proper, then your undervolting is just a stop gap, not a proper(long term) solution.

PBO varies from chip to chip, some people have enabled PBO and haven't seen any thermal issues. Others have enabled PBO and seen temps climb up a little. Thought I'd address that and no PBO doesn't equate to undervolting.

Use Curve Optimizer in BIOS and set all core to negative -20 to start with. Alternatively try to set ECO mode to 65W and test. If it was habitually running too hot you may even gain performance.
