    So I assembled me a new home rig this weekend, and since previous rig (I participated in build) was more than 10 years ago, I was nervous about one particular moment - amount of thermal paste (along with the method of applying).
    I did a 10 minutes stress test afterwards and CPU`s temperature stayed near 60C for the length of test.
    I guess it is OK for air cooling (of 10-core CPU)?

    I am guessing you have an Intel CPU.
    There are a few factors:
    Voltage on default?
    Overclocking? IF yes, how much?
    What cooler and how many fans?
    Ambient temperature?
    Those are the first questions or factors I logically check first.
    But having near 60C during stress testing for a 10 core CPU is not bad, not bad.

    Correct. :cool:

    On default (auto).

    No overclocking.

    (one fan)

    ~25C

    10 core Intel? WOW! Congrats! ;)

    Temps look nice, even for "only 10 mins".
    Try to watch for single core temps. Chance may be minimal, but I once found a core (of a quad core CPU) went way hotter than the rest. After dismantling the cooler again I saw the thermal paste didnt spread to one side of the die correctly (I didnt apply it in the first step, a friend did), so if say 2 or 3 cores of your 10-core get way hotter than the remaining 7 or 8, your paste probably didnt spread right.

    But from what I read, everything is fine. :)

    @anticupidon Thank you.

    @386SX Thank you. Good idea - to stress test on smaller number of cores.

    One thing I noticed which made me sad a bit - with SpeedShift enabled in BIOS I am no longer the master of P-states. Windows power plans are just ignored in that part.

    We are not British, so we have a central heating in houses (in towns, of course).

    I didn't mean that, but I agree, it's a good test. ;)

    I originally meant you should stress all cores in a parallel manner and watch for temps, because if 9 of 10 cores stay under 70 degrees and 1 core is at 90 degrees you should reseat the cooler. With same load on all cores the difference between temps should be minimal.
    That's what I meant before. :)

    OK. I will do that too. I monitored only overall CPU temperature.

    Update: Seems temperatures are close on all cores.

    Hi there

    Something like NH-D15, Thermalright Le Grand Macho RT or Deepcool Assassin and many others should be able cool any CPU with OC or without the OC, I have run 5960x with 4.7GHz OC with NH-D15 and temperatures I have seen in 70-80's on PKG

    I would monitor PKG temperatures and you will see, depending on case and fans used this shouldn't be a problem cool 10 core CPU, create custom fan curve for fans as first, try Aida64 for benchmark or free Asus Realbench which I use there and don't use Prime95

    Personally I would keep eye on PKG temperatures, try keep it under 85-90°C

    If I would recommend get good TIM like Thermalright TF6 or TFX, Noctua NT-H1 or Thermal Grizzly Kryonaut

    Hope this helps

    Thanks, Jura

    I usually mount a cooler at least twice.... The first time, just to see the pattern made during mounting. If the entire CPU isn't covered, I slightly increase the amount of thermal compound and try again. I usually just put a pea sized amount of thermal compound right in the middle of the CPU to start. On rare occasions, I take the time to actually spread the thermal compound....

    60C is just fine, so long as all the core temps are close together.

    Thanks.

    I use CPU-Z, Intel Extreme Tuning Utility for stress test.
    And since CPU cooler is Noctua NH-U12S chromax.black it comes with Noctua NT-H2 thermal compound.

    Thanks.

    I did the pea sized approach too. Good algorithm you described.
