Greetings,I am using SpeedFan for measuring CPU temperature.In it I have the following
Temp1
Temp2
Temp3
HD1
GPU
Core
HD1
I am wondering what are those temp 1,2,3 and Core?
Temp 1 and 2 always have low temps,around 28C,but when I start CPU torture tests like Prime95 or Intelburntest,Temp3 starts to raise slowly,and reaches around 55-58C if CPU(FX 4300) is overclocked at 4.6ghz,or around 62-65C if overclocked at 4.8ghz but also the "Core" which stays around 40C.So if Temp3 is CPU,what is Core?
Edit:So it looks like HWmonitor is saying that CPU temp is 5C(Core in speedfan also reports 5C).HWmonitor also reports Those three "Temps" just marked differently by numbers 0,1,2.

Not quite.

Temp1, Temp2, and Temp3 are likely random sensors somewhere on the motherboard. Likely the chipset, VRM, and CPU socket temperature for temp 3 since it follows when stress testing. As each board varies and Speedfan tries to cover everything you will get some weird stuff.

CPU cores should be labeled as such.

FX chips do not properly measure low temperatures and they use a calculated offset rather then the 'expensive' sensors that Intel goes for.

I had to give up on speedfan since it didn't work with early Haswell equipment, haven't gone back since.

core is the psu my core temp went to 80 i saw a bright flash and the pc shut down i tested my components it was all ok apart from the psu it had gone so core is psu

anything under 70 is ok if it rises above that id suggest aiming another fan at the psu and check the psu fan spins freely and isnt jammed with dust
