        I have an Asus Z170M-PLUS.

        Obviously I know about fan configuration in BIOS.

        The problem is that temp spiking for a second isnt something you can configure your fans to.

        If for example my system running 20 degrees the fans rpm is about 700.

        When the temp spike to 40 degrees and a second later gets back to 20, the rpm of the fan goes up to 1500 and back to 700 in a matter of second.

        Its like sitting next to a vaccum cleaner...

        Only thing I could configure is for fans to run at 40% const up to 50 degrees, but thats just ineffective use of cpu/case cooling.

          I actually opened this thread for my problem, the answer I've got there is that its fine.

            I understand the reasons for not using solder ... there are other articles that explain the issues (one of which, not mentioned in your article, is the smaller die size on Kaby Lake).  My question was not about solder, but about high quality thermal compounds like the Coollaboratory liquid metal compound.  The only logical reason for Intel not using this has to be long term stability ... but with all of Intel's resources, I would be surprised if it was unable to come up with a TIM that performed better than the one it uses and was still stable for 5+ years.  Anyone running their CPU at stock frequencies would never see any degradation, and overclockers know that what they do stresses their CPU and will therefore reduce its life.

             

            I think your position is "Intel Knows Best" ... but we know from past releases that even Intel has messed up on its thermal solutions and has released a new variant to fix the problem.  I wouldn't be at all surprised if this happens with Kaby Lake.

             

            Cheers

                Here's the breakdown:

                 

                Indium Solder - 81.8 W/mk (Used on 2nd Gen Sandy Bridge and earlier)

                 

                Liquid Metal TIM

                 

                Thermal Grizzly Conductonaut - 73.0 W/mk (Newest Product)

                CoolLaboratory Liquid Ultra - 38.4 W/mk

                CoolLaboratory Liquid Pro - 32.6 W/mk

                 

                Typical Silicon TIM

                 

                Arctic Silver 5 - 9.0 W/mk

                Gelid GC Extreme: 8.5 W/mk

                Arctic Cooling MX4 - 8.5 W/mk

                  From my experience Thermal Grizzly does not perform as well as liquid ultra/pro. So not sure why it is showing a better watt per unit area.

                   

                  I have tried both on a delid chip and the Liquid Ultra does a much better job of moving the heat to the IHS. Now when it comes to the IHS to block there is not as much difference and the Grizzly while not as cool (maybe 3-5C warmer) does a much better job in the long run on the top of the IHS.

                   

                  Plus it doesn't have all the side effects to staining the block/ihs or removing the etching/writing on the ihs.

                   

                  That being said though I still challenge the w/mk numbers for the liquid products. Do you have a theory to why they perform so much better, but are showing half the w/mk of the thermal grizzly?

                   

                  *edit* nvm this is a new liquid metal from Grizzly line. That would explain the difference. Looks like I will need to order some and give it a go.

                    Coollaboratory Liquid Pro has a thermal conductivity of 80W/mK ... where are you getting your data from ???

                      I have same problem to with fluctuations in temps

                       

                      and mine is water cooled with separate radiator for GPU and CPU and about 10 cooling fans

                       

                      over kill I know but it's the only way to keep mine sort of cool at ideal and at stock

                       

                      knew I should have waited for ryzan but went with Intel as thought they were the leaders and good at what they did but now I have an extra heater in my house lol

                       

                      the problem is I use my system for after effects and 3d design now checking temp uses up all my time instead of being creative.

                       

                      Please Intel sort this out..

                        how cool it runs the CPU and radiator size?

                          EK Cool stream pe 360 triple is what I'm using 200ml

                           

                          And I'm getting strange fluctuations it seems to jump quickly and high from 40 on boot to 65 then back down to 29 then jumping back up to 65 when I have even made sure everything is turned of on start up it just seems strange to me. I've even gone through the hole water loop re seated block still no change.

                            I see a lot of OCCT runs here; is that when they are spiking? Because that tool is outdated and indeed causes spikes; it's designed to do this and thus not a good indicator. Also Prime shouldn't be used, it doesn't fit in modern CPU environments and stresses modern chips way, way more than it should and this causes issues. Try Asus ROG real bench, cinebench etc.

                              I sold mine Intel Core i7 7700K and bought Ryzen 1700. I'm absoluttely happy with mine new CPU. No temperature spikes at all! Maximum temperature after 48 hours stress testing (Prime95 29.1.14) on box cooler is 58C (ON BOX COOLER CARL!). Temperatures very smoothly grow up when CPU load at 100% and smoothly fals down when 0% (SMOOTHLY INTEL! ).

                               

                              Thanks everybody who try to help in that thread. I hope you'll get some answer from Intel guys.

                               

                              P.S. Bye bye Intel, i'll never buy CPUs from you again. NEVER!

                                I like how you said "indeed" there... stop please talk nonsense. Indeed... yes. Its outdates and this is why it cause temp spikes. Its funny. Btw tested mine new Ryzen 1700 with OCCT also. No spikes at all

                                  Lucky you, unfortunately I don't have the funds to do the same .  However, I can tell you that from now on I'm buying AMD, I don't care what anyone says about them anymore.

                                    I can't say that the 7700K  will be my last Intel CPU, i have always bought Intel CPUs, l've never had an AMD CPU and i won't never buy one, i just hope that Intel's next CPUs will be better.
