      • 1,095. Re: Thermal sensor issue i7-7700k?

        My comments are: (a) in both cases, the processor didn't get hot enough to worry about (these are still fat, dumb and happy temperatures for the processor; worry if the temperatures are reaching above, say, 90c) and (b) the minor difference in performance likely results from the greater number of background (maintenance) tasks constantly running in Windows 10.

          I agree with what your saying this test didn't stress the CPU but what it is strange is the fact a OS that is not supported can get similar scores and also have less spikes when opening programs also the fact that idle temps are 5c lower if not more on my setup ON 8.1. Obviously windows 10 is a bloated mess and i think that's playing part in the temp spikes its not the whole picture but the problem is more evident on windows 10 OS.

            Well, I have been saying it was a bloated mess since the preview versions first appeared - and it has only gotten worse with each subsequent update (Spyware *does* take a lot of CPU cycles, after all).


            Lately though (especially with the Fall Creator's Update), it has reached the point where, with a 7th gen Core i7 NUC (NUC7i7BNH, which has Core i7-7567U), a system sitting idle could still see temperature spikes sufficient to cause (require) fan response. As to what it is in the background that is causing this, I am unsure. I regularly listen to the NUC while working on other systems and, when it spikes, I jump on to see what caused the spikes. Unfortunately, I am usually too late; nothing stands out...

              I'm going to jump in on the bandwagon also as someone who just purchased the i7-7700K and am very unhappy with the temperature spikes. I upgraded my NAS from an i5 to the i7-7700K for the extra threads and speed increase. I am NOT overclocking this processor. I am seeing spikes of 20 - 30C. I am running some computational intensive tasks (BOINC) and I see the temperature range from 50C to 78C. I have BOINC set up to use 75% of the processors 50% of the time. With these task running it should reach a certain temperature and stay there and not fluctuate so much.  The temperature spikes are causing havoc on the fans. They ramp up to full speed then slow down then up again and then down again, repeat. I wish I had seen this thread and the dozens of others out there before I purchased this.


              @Intel - It looks like Intel has know about this for a while. Are you planning on addressing this? If not can I send my i7-7700K to Intel in exchange for an i7-7700? I'll take lower speeds over one with wild temperature spikes..

                For someone who has come from using the i7-4790K, i7-6700K and now the i7-7700K, the increased idle and load temps even if within specs is not welcome. I didn't pay extra for cooling to have the CPU operate at a higher temperature.


                We need a solution not a short fix like AVX offset,  etc.

                  Never pass 63 C  after change manual vcore and ppl oc, turbo disable. I think I should have better temps if i don't use only 1 fan on liquid block cause of motherboard memory not permit to put second fan. I have ****** airflow also in case, 1 fan 120!

                  I see something interesting on youtube, a guy show it exist difference  in temeprature with different motherboards. I think I was wise with what I chose!

                  Time: 3:11 show what i say!

                  Hope this will help you!
