    I7-7700K Suddenly overheating - faulty?

    Schabracke

      Hi,

       

      specs:

      I7-7700k

      MSI Z270 Gaming M7

      Watercooling: Corsair H100i v2

      TIM: Liquid Metal

       

       

      yesterday i was running a game when suddenly all my Fans went to 100%. I checked the temperatures and saw that the CPU was at 100+°C. I run this PC for Months and havent changed anything. Normal Temperatures are max 60°C on full load. I never overclocked the pc.

       

      I waited a day, and when i startup the PC, all the fans are immediatly running at 100%, before the BIOS Screen even shows up. When i enter BIOS, i see that my CPU runs at 60°C instantly and climbs then to 100+.

       

      Is the CPU faulty? How can this happen from one moment to the next?!

      Can the liquid metal be the problem? I use it on my second PC too, for over 2 Years already and Temps have never changed.

      I dont know what to do, please help, any advice would be great.

          Hi Schabracke,

          I understand the Intel® processor experienced temperature spikes and the processor has never been overclocked. Let me help you on this matter.

          We appreciate the feedback you have provided, the reported behavior of the 7th Generation Intel® Core™ i7-7700K Processor, showing momentary temperature changes from the idle temperature, is normal while completing a task (like opening a browser or an application or a program).

          In our internal investigation, we did not observe temperature variation outside of the expected behavior and recommended specifications. For processor specifications, please refer to the datasheet below:
          https://www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-desktop-s-processor-lines-datasheet-vol-1.html

          Most motherboard manufacturers offer customizable fan speed control settings that may allow for smoother transition of fan revolutions per minute (rpm). Please consult your motherboard manufacturer’s manual or website for instructions on how to change default fan speed control settings.

          We do not recommend running outside the processor specifications, such as by exceeding processor frequency or voltage specifications, or removing of the integrated heat spreader (sometimes called “de-lidding”). These actions will void the processor warranty.

          Regards,

            Hi,

             

            sorry to be rude, but this did not help at all. Your answer showed me, that my Description was not carefully read and the answer was copy pasted. This is bad service.

            If the CPU is at 100+°C and the PC is throtteling and crashing, i doubt that this is normal. In addition, it's not a temporary peak, but as i wrote, its a constant climb without any recovery at all. Besides, as i wrote, temps were at 60°C max on full load before.

             

            However. I figured, that the CPU wasn't the problem, but the Pump of my Watercooling. I thought it was working because the LEDs were still intact, reacting and when i touched the tubes, it vibrated. But the Vibration wasn't from a working pump, but were caused by the heating Water in the Cooling Part. When i connected the pump to another PC, i heard and felt nothing, which told me the Pump was faulty. Also i tested on another PC which Symptoms would occure, if i remove it's Pump from Power Supply Connector on Mainboard -> Same symptoms.

             

            Hope i could help someone.

             

            This matter can be closed, thanks.
