FX 8120 Zambezi at 3 degrees?

post #1 of 5
Thread Starter 
Wake up, turn on PC, start speedfan to slow down rad fans parallel wired, noticed that my CPU is 7 degrees cooler than usual, thought the sensor is screwing up, thought my pump is overworking, I don't know.

Under 70% constant load:



On idle:



Restarted, and it's back up to 12-14 degrees. How does this happen?

That is pretty odd. I'd recommend turning the PC off and taking a look at idle CPU temps in the BIOS. If they are that low, then it's likely the sensor is off. If you want to be 100% positive that it's the sensor acting up, buy a new temperature sensor and put that in there. Not much I can really gather from all of this.

First of all you should use a better software to monitor your temps. Speedfan is off in my system too for some reason. The 7°C degrees is definitely a wrong reading unless your ambient is 7°C or lower too. From what I've seen it is common for AMD chips to report low temperatures at idle but they should be accurate when you give it some load.

Try using HWmonitor? (Or Coretemp, realtemp, HWiNFO64?)
Speed is known for terrible temperature reporting!

NONE of the current temperature monitoring softwares are accurate at guaging the new APU and FX chips until and above 26c. Even then readings should be taken with a grain of salt.

The only one I have see to be accurate below 26 degrees came with the motherboard.
