Hardware monitor seems to be measuring my temps wrong..

[lunaris ツ]

I use OpenHardwareMonitor to monitor my CPU and GPU temps.

My CPU temp will often fluctuate very strongly between 20 and 50 degrees (all measured in Celcius, btw).
I run an AMD-8300FX processor and I feel like an idle temp of 20 is very low and must be incorrect. I would be very happy if this was the actual temperature, however I have suspicions considering AMD usually runs warm (in my experience the avg idle temp is 45-48 on most AMD processors).

Could this number actually be correct? I can't find much information on the 8300 so I can't verify things like ambient idle temp or I would.

Any help is appreciated, thanks!

Offset temperature - those readings are indeed (most likely) incorrect.

^ might be worth a read.

Edit: idle temp of 45-48°C is rather high though, like way too high.

None of those hardware monitors are accurate for AMD FM2/AM3 stuff; cause the Devs 100% dont care about AMD users cause they are not the majority users.

Use AMD OverDrive

You can ignore idle temps as they are useless until you get to about 45c on the cpu internal.
Here's a quote from an AMD senior tech director.

Concerning your question regarding the temperatures with your processor. The maximum temperature threshold is 62 Celsius which set for the internal die (core) temperature of the chip. The core temperatures have an equational offset to determine temperature which equalizes at about 45 Celsius thus giving you more accurate readings at peak temperatures. The hindrance in this is the sub ambient idle temperature readings you speak of.

The silicon and adhesives used in manufacturing these processors has a peak temperature rating of 97+ Celsius before any form of degradation will take place. The processor also has a thermal shut off safe guard in place that shuts the processor down at 90 Celsius.


The Cpu temperature is read form a sensor embedded within the socket of your motherboard causing about a 7-10 Celsius variance form the actual Cpu temperature, which may be what you are reading about on the net.



You can use an application called AMD overdrive, that will allow you to monitor your temperatures accurately.



As long as your core temperature has not exceeded the high side of the 60 degree mark for extended periods of time you should be ok. 62 degrees holds a generous safety net to begin with.
