I recently built a PC shown above. However, unfortunately, during the summer, my room tends to get quite warm, and the processor's temperature often exceeds 90°C. While I know this model tends to run hot and is still safe to use, I would like to try lowering the temperatures before summer if thats even possible. Many people online recommended undervolting, which I have done based on tutorial videos. With all cores set to negative -20, I noticed fewer crashes, but there are still occasional freezes. These occur only when idle and never during gaming. I used the following settings: PPT: 120, TDC: 80, EDC: 120, but during Cinebench stress tests, the temperature still rises to 84-85°C, and I get a score of 845 points. It's like nothing has changed on every setup. Is there any solution or cooler that could help me? Perhaps a 360 AIO cooler? I'm looking for people who would be willing to help a beginner, either here or on Discord. Apologies if I'm asking something silly in advance. Thank you!

So you have already used Curve Optimizer to set a -20 across all cores, and appears you've also reduced power limits slightly from stock?

To address the instability I would back the CO off to -15 and see if that fixes the instability.

To address the temps, in the BIOS Settings, AMD Overclocking you could also enable Platform Thermal Throttle Limit which allows you to specify a max temp. Once it reaches that temp it will begin to throttle frequency and voltage. Further down that same screen there is also ECO Mode which you could use to set a 65W TDP for example, rather than the stock 105W TDP. Either one of those settings is a tradeoff, it's going to sacrifice performance for lower temps.

The other thing you could do as you mentioned is switch to liquid cooling. You've already got one of the best air coolers in the Tr Peerless Assassin, so you'd need a pretty good AIO to get even a 5°C drop, and even with the best 360 AIO you may see only up to a 10°C drop, depending on ambient and how loud you run the fans.

I have constant random freezes since yesterday. I've tried to set BIOS settings to default, XMP off. Still have random freezes. The weird thing that these crashes only happens when the pc is at idle, when I gaming there is no problem at all. I tried windows reinstall but the issue is still happening. I'm just hopeless.

Hi,

i know that several users had resolved crashes with PC on idle disabling C states in BIOS. While i can't reccomend it at 100% (for possible higher consumption at idle) you could maybe give it a try and see if the crashes disappears.

Hi Stefano,

Thank you for the suggestion.

Yesterday I've set power supply idle control to typical and global c control to off. No freezes since then, but I cant say for sure its working, I need probably 2 or 3 days.

Did you adjust the Curve Optimizer as suggested? A -20 setting may be too aggressive leading to instability at idle. Try changing this to -15 and see if that makes a difference.
