What should I take as correct cpu temperature? CPUTIN (85C) reading or separate core readings (39C)?

I have installed Speed Fan, Real Temp and HW monitor and in all 3 and also in bios the CPU temperature is given as 85C
and core temps are given as 39 C and 40 C.
What should I consider as correct temperature.
And why is the CPU temp 85C. Is it something wrong with the sensors or is there anything I should do about it.

Thanks to anyone who can help.

  1. Sounds like bad cooling, put your hand on the heatsink (ground yourself ((put your foot on a floor lamp or something))) and see if it feels hot.
  2. I did it and it feels pretty warm not too hot though.
    Please note that I don't have a fan attached to the heatsink

    What I do now?
    Thank you for replying to my question.
  3. Also when I ran battlefield 3 for a while and checked the temps it read about 65C on both cores.
    The cputin temp was the same without any variation on the graph.
  4. That is your problem. You need a fan. It is a terrible idea to run it without one. Get a fan, like now. Go to Radio Shack and get one.
  5. I have a fan attached to the cpu. Do I need to attach a separate fan to the heatsink as well. Or is one ebough.

    I will try to attach a photo of the inside of my computer so that u can have a better idea.

    Thanks again for replying to my question
  6. I'm not sure you're getting your parts straight. Your heatsink connects to your CPU, and the heatsink has a fan on it.

    Here is the picture of inside my computer.
    Im far from an expert so dont know much about this stuff.
    Hope the picture will give u a better idea about my problem.
    Thanks


  8. I thought the one with the fan was the cpu and the alluminium one is the heatsink.
    So when i said my heatsink doesnt have a fan I was reffering to alluminium one next to the processor.
  9. That is a heatsink, not the one I was talking about. Looks like you have somewhere around no airflow, a new case with 3-4 fans will solve your problems.
  10. I'm a bit short of money at this stage. Isn't there any other cheaper way to do it.
    Thank you
  11. Take the cover off and blow a desk fan into it, I guess?
  12. Ok ill try that.

    One more thing please. Iv noticed that the frequency in my cpu is changing rapidly. It goes from 2799MHz to around 2200MHz within seconds. Stock speed is mentioned as 2.8GHz.

    Is my CPU throttling due to overheating?

    Thank you.
  13. Seems like it.

    I did this and the cpu temp which on 84 did not change it remains constant throughout.
    The core temps which maxed to 71C earlier dropped to 69C but that does not seem much.

    Since the cpu temperature remained constant for about 4 days could it be that a sensor is broken or something.
  15. Possibly, yeah, because if that doesn't change it, nothing will. Try reapplying thermal paste, and if that doesn't do anything, it's the sensor.
