I'm currently using a Ryzen 7 7800X3D and have noticed something concerning: HWiNFO is showing a maximum CPU temperature spike of 128°C. While my current temperatures are perfectly normal (hovering around 60-70°C under load), and during a two-hour gaming session, it never went above 70°C, that max reading has me worried. Here are some details:
- No manual overclocking has been done.
- Precision Boost Overdrive (PBO) is not aggressively tuned.
- There's no thermal throttling recorded.
- CPU limits (PPT, TDC, EDC) are not being hit.
- The system remains stable with no shutdowns or crashes.
Right now, the idle temperature is around 45-55°C. I suspect this is a momentary spike, not a sustained issue. I have a few questions:
1. Could this be a sensor glitch?
2. Can Tctl report a spike that isn't reflected in the actual die temperature?
3. Would a brief spike like that cause hardware damage, or would the CPU have throttled or shut down first?
4. Is there anything specific I should monitor to verify this?
For context, I had one high-temperature event previously that caused a brief thermal throttling, so I'm keeping a close eye on temperatures now. I'm trying to determine if I have a cooling mounting issue, a transient voltage spike issue, or if HWiNFO is just exaggerating.

Definitely sounds like a bug to me. The CPU would shut down before hitting that temperature, so I wouldn’t worry too much. Just keep an eye on steady temps while gaming.
It sounds like that spike is likely a glitch. Your CPU is designed to shut down if it really reaches that temp, and since you didn't experience any shutdowns or throttling, it's probably safe. Many users have reported similar issues with HWiNFO showing unrealistic max temps. Also, 128°C is way over the limit for your CPU!
Yeah, I had a similar experience with my CPU temp reporting. It’s probably just a bug with HWiNFO's readings. Always good to check other monitoring tools, just to be sure!
I think it might just be reporting the max value incorrectly. Sometimes when the CPU transitions between C-states, the readings can go all wonky on monitoring software like HWiNFO. I wouldn't stress it too much right now.
Exactly, 128°C is insane! Most CPUs have safety features to prevent any actual damage from occurring, and yours seems to be working just fine.
