HWmonitor shows a sudden jump in CPU temps during overclocking on an AMD FX 9590.
HWmonitor shows a sudden jump in CPU temps during overclocking on an AMD FX 9590.
Hello everyone! I'm trying to connect with someone who experienced a significant spike in HWmonitor, especially concerning the package temperature. I've been dealing with occasional random freezing while playing Forza 4, and my thermal margin is being pushed for all other components like VRM overheating. I think this might be a serious issue. My current reading shows an incredibly high 129°C on the package temp in HWmonitor—equivalent to 263°F! This occurs during idle or under load.
I'm using AMD overdrive and HWmonitor to investigate, but I'm unsure if this is just a glitch or a genuine problem. This issue has appeared with an older version of HWmonitor and now the latest one.
Update: Just got a reading of 225°C! I'm taking a screenshot.
I'm running a 9590 overclocked at around 5.2 MHZ, max voltage 1.500V. Temperatures are just under throttling during stress tests but spike to over 10 degrees while gaming or under load.
Tomorrow, I plan to replace the chip with liquid metal and reapply a high-quality thermal paste on the VRM heat sink to see if it stabilizes the VRM temps, which currently read 136°F (measured with a cooking thermometer on the heat sink).
I'll try adding screenshots to my post. If they don't help, please let me know what I've shared so far. Thanks!

When you are using a thermocouple to measure temperature the connection has to be secure. It literally determines the temperature by measuring the very small changes in resistance. So any problem with the leads or the connector will result in those spikes that you mention due to just vibration.
It is a very common issue.
Especially if there is a weakening of the leads, the spikes will get worse. And eventually one of the spikes will become permanent.
When working with a thermocouple to gauge temperature, the connection must be solid. It actually sets the reading by detecting tiny shifts in resistance. Any issues with the leads or connector will cause those fluctuations you notice from just movement. This is quite frequent. Particularly when the leads start to weaken, the spikes intensify and may become permanent.
Thanks for your response! I meant a thermometer like the one you use in a cooler, not a thermometer for CPU monitoring. I’m interested in real testing tools and an oscilloscope. I have some basic electronics skills, and your comment reminded me to check for poor solder joints. However, I suspect it might be something else—like voltage spikes in my software or a component that can’t handle the current I’m applying with one of my settings. I recently replaced my CPU with liquid metal, which lowered my idle temps by 7 degrees and reduced under load temps to 11–13°C. I haven’t installed a VRM heat sink yet. I’ll keep learning more about overclocking; I’m aiming for around 5.3 MHz, roughly 50 MHz lower. It probably depends on the CPU and motherboard, but the VRM temperatures concern me. When they reach 145°F during gameplay, I get stuttering and it stops when things cool.
I’m open to any suggestions or knowledge that could assist! Thanks again!
I think I wasn't precise.
The motherboard uses thermocouples to track CPU and board temperatures, which can be adjusted in the BIOS. HWmonitor simply displays those readings.
A thermocouple functions as a basic electronic temperature sensor.
Some monitoring tools have issues, often due to driver problems. HWMonitor tends to work well, but these problems usually stem from discrepancies between reported and actual BIOS values. The most reliable method is using the motherboard's own monitoring software.
I think I wasn't clear about that. The motherboard uses thermocouples to track CPU and system temperatures, which you can adjust in the BIOS. HWmonitor just displays those readings. A thermocouple functions like a basic electronic temperature sensor. Some monitoring tools have issues because they don’t match the BIOS-reported values. The top choice remains the motherboard monitoring utility.
