Processor that constantly changes temperature

Solved
macdesse -  
Hello
since I changed the thermal paste, my temperatures change when I play. When I’m on the same game
I go from 95 to 65, then it goes to 80, 72. Why do the temperatures fluctuate constantly? Is it serious? THANK YOU for your help.

    Hello,
    as long as it doesn't affect game performance, it's not too serious.

    Does it not stabilize at a certain temperature?

    Is it a desktop or a laptop?

      Hello and THANK YOU, no it does not stabilize at a temperature; it goes from 80 to 65, 90, 60, 80, 70, it’s always like this. I have a desktop PC. Why does it do this? Sometimes the game stutters. What should I do please?

      @macdesseLook in the BIOS or via the manufacturer's utility for the motherboard to set the fans to maximum when it reaches 70°C

      Maybe you didn't apply enough thermal paste, set the power option to high performance in Windows.

      @jumulkaHello and a big THANK YOU
      I'm terrible with computers and I'm afraid to touch the BIOS. I don't know how to use the graphics card utility. As for the thermal paste, I'm not sure about my application; I put the size of a pea. The thermal paste is: THERMAL GRIZZLY. It's the only one I found. Since I'm not good at this, could you please explain to me how to enter the BIOS or the motherboard? A huge THANK YOU for your help!

      @macdesseIt’s at the computer startup, usually Escape, F2, F10, or F12, depending on the motherboard.

      What’s your motherboard and processor?

      @jumulkaHello
      my processor: Intel(R) Core(TM) i7-8700@3.20GHz 3192MHZ, 6 cores, 12 threads
      my motherboard: HP motherboard manufacturer
      motherboard product 86E9
      motherboard version A(SMVB)
      it's quite strange that it fluctuates between 65 and 95 constantly
      what do you think about the thermal paste? and my hardware?
      my computer: HP 290 G3 MT business PC
      THANK YOU for your help

    Hello,
    Here’s a tutorial that explains well how to replace thermal paste:
    https://fr.ifixit.com/Tutoriel/Comment+appliquer+de+la+pâte+thermique/744

    It seems to me that if you applied the equivalent of a pea, that’s way too much: maybe you should redo the operation to properly follow the tutorial's recommendations, especially regarding cleaning and drying. Knowing your processor, also look for recommendations on how to apply thermal paste (in a cross, as a small dot, ...)

      Hello and THANK YOU, I have restarted putting the dough (in a cross shape, grain of rice, in the middle, spread on the processor) 5 times. (apparently spreading it causes air bubbles) why such a big difference in temperature? THANK YOU for your help.

    download OCCT : https://www.ocbase.com/download/edition:Personal

    run a CPU test and check the temperature to see if it fluctuates or stabilizes, and also check if the processor frequency (core 0 frequency tab) is stable and at what level

      and THANK YOU for taking a bit of your time to help me.
      I made two little videos but I can't send them to you, how can I do it please?

    Well, nothing alarming, the temperature remains stable at 83°C, which is a bit high, but still acceptable considering that under normal usage the CPU is never at 100% all the time, and there is no frequency drop for the CPU, so no issues to report on that side.

    Can you do the same test on the graphics card? (the GTX 1050 Ti tab, then)

    And run this benchmark test: https://gpu.userbenchmark.com/Software
    (provide the link to the test result)

      @macdesseis your screen properly connected to the graphics card (horizontal ports) and not to the motherboard (vertical ports)?

      because the benchmark tested the igpu (the processor’s graphics chipset) and not the graphics card, so that suggests that the screen is not connected in the right place. as a result, the graphics card is not being used at all, and the use of the processor's graphics part contributes to increasing its temperature.

      @macdesseThe graphics card is slightly below average (just a little, 30.4% compared to an average of 30.8%), but it's still good; you shouldn't normally have any issues playing.

    Probably a motherboard issue. However, changing the motherboard for a PC like this is not straightforward; they are generally not in standard formats and finding the same one is not particularly easy, hoping that the new one won't cause any problems either.

      Hello and THANK YOU. I removed the processor and I noticed that one pin on the processor socket was bent. Could this be the cause? And how can I straighten this pin? Thank you again for your help.

      @jumulkaHello, I will try to straighten it out, and for the CPU cooling? What should I do, please? I used the HW-881 thermal paste; what do you think of this paste? Thank you for giving me your opinion.

      @macdesseI don't know if the temperature always jumps to 95°C and then drops immediately to 65, I can't tell you more than what I've already said.

      That's why I also said to test with an i3 or i5 because they heat less.

      I can hardly find any information about your thermal paste.

      @jumulkaHello
      I also can't find any information on this part. Regarding the temperature, can the motherboard cause the processor to heat up, and how can I know which elements may cause overheating?

    Hello
    after a few days my processor is starting to overheat while I play. Can someone tell me what's happening with my computer, is the processor broken? The motherboard? I took it to a repairman who didn't understand anything. He doesn't see what's going on. Please help me. THANK YOU for your help.

      There may be a temperature probe issue. Is it rising to 95°C?
      Is it causing you performance problems as a result?
      Do you know what the repairman tested?

      Try to disable the turbo boost of the processor in the BIOS if you can.

      @jumulkaHello and a big THANK YOU. I think the technician did not test anything. They don't have the equipment or the skills here. He simply told me that he didn't understand, and that’s it. How should I disable the processor's turbo boost, please? I'm sorry to bother you; you are the only one who can help me. Again, a big THANK YOU.

      @macdesseYou need to enter the BIOS, go to the configuration tab, and see if there is a turbo boost option (or maybe just turbo or boost); also check in device options.

      According to what is in the manual on the HP site, there is no such option, but manuals are not always comprehensive.

    Hello
    I don't have turbo boost. And the manual is in English, I don't understand English. What should I do, please? Where can I find these sensors and what do they look like? THANK YOU for your help.

    1. jumulka
      It's a sensor integrated into the CPU, you won't find it. You can try changing the processor to see if you have the same problem; given the graphics card, even with an i3 you should have almost the same performance, or otherwise an i5.
      In the manual list (page 6), it states that the card supports the 9th generation, which are more powerful and cheaper than the 8th, and also easier to find, but I can't guarantee 100% that a 9th gen processor will work, normally it should (at worst you can always return the processor if it doesn't work) > > http://h10032.www1.hp.com/ctg/Manual/c06520280.pdf

    Hello
    and a big THANK YOU. I have an i3 processor, if I install it, will I be able to see if it's overheating? The problem is if I buy a new processor, it will never be refunded. It doesn't exist here. We can't know if it's the processor or the motherboard that's messed up? THANK YOU for your help.

      it depends on the i3, for your computer it’s i3-8100 or i3-9100

    Hello
    I don't have an i3-800, I would like to know how this happened? The computer is only 1 year old. It only overheats when I play a game; if I watch a video or a movie, it doesn't overheat, it stays at 24-26 degrees. THANK YOU for your help.

    1. jumulka
      It's normal for the computer not to heat up when it is not or little used.

      If it's only 1 year old, you can try to check with customer service, although I don't know if opening the case voids the warranty.

      there are no guarantees here. I would like to set my processor to performance and push it to 90% but I forgot how to do it, can you please help me? THANK YOU for your help and I apologize for bothering you. please tell me why this happened.
