OK...one of the hardware monitors I use...showed this for my X570 Tomahawk and 5950X
 
 

When I am running Cinebench or other benchmarks...all of the temps at full load are around 70C.  What you see above is idle...with slightly higher package because I am running Open hardware monitor...and when it opens...as with even CCD...will splke.  When not spiking...even the package temp is around 33-35C with the Corsair H115i RGB Pro to cool the chip.  Normal?

    If it's just spiking momentarily that's fine and could be a couple things really. Usually when you open a program or something the CPU cores will go from idle to full single core turbo at 4.9Ghz in the case of a 5900X and 5950X. Obviously to do this it will need a voltage increase and with voltage increase you inevitably get a temperature increase. This happens so quickly that the cooler doesn't have time to dissipate the heat from the momentary blip in voltage. Other thing it could be is when opening a monitoring program the sensors could be getting polled and may cause them to report a momentary false temperature. 
     
    If the temps under sustained load are OK, you have nothing to really worry about.

    Exactly what Craptacular said. I noticed some monitoring programs are listing my speed at 4.8GHz & temps in the upper 50C range... but then I open more detailed programs (AIDA64) and it shows me one core is doing that work at that temp and the rest are idle/low use and low temp.

    Depending on how the monitoring program is coded to show you the percentage or temp, it will differ. A good rule of thumb is to always go by the individual core temps, not the CPU package readings.

    Its completely fine the chips run a little on the hot side but its within spec. Even on a custom H2O loop my 5950x gets a little toasty but damn is it fast.

    Nice to hear others having similar (non) issues...
     
    It's been driving me crazy to see temps like they are...but if others are ok with it....I am too, I suppose.

    Yeah; the 5900/5950 cPUs are packed to the gills with cores and run hot. Checking out people who have 5600/5800 they usually see 10-15C lower idle temps compared to what we're all describing.
     
    Trade off for that higher core count.

    Actually the 5800X is considered a "Hot Head" because of the single CCD      https://www.techpowerup.com/forums/threads/ryzen-5800-owners-complain-about-very-high-mt-load-temps.274465/
     
    The upper temp limit on the 5900 and 5950X is 95C, and the 5800 is 90C.  The load temps on the 5600, 5900 and 5950X are lower.  However...once tamed...they really shine!  All in all...the 5950X may idle slightly higher than my old i7 7820X, but at full load...the Ryzen is cooler and much more powerful.

    Yeah, that's more of what I was getting at. My 6700K would idle around 33C; 5900X is around 48C. Load is still around 70C when doing heavy CPU gaming.

    Re: For Ryzen owners, question about Temps 2021/02/14 04:48:23 (permalink)
    I also was wondering about my temps of my Ryzen 9 5950X and i tested some things.
    The PBO that was enabled by default at my mainboard and that caused this:
    Cinebench All Cores -> 60°C
    Cinebench Single Core -> 70°C
    Cinebench 2 Core -> 80°C
    And it really seem to be the PBO configuration that causes this.
    PBO just boost your clockrate and voltage until one of the limits are reached.
    Limits you can set are for example:
    CPU Package Power (W)
    TDC (A)
    EDC (A)
    Temp (°C)
    Clockrate (MHz)
    ...
     
    moreover with the Curveoptimizer you can set the clockrate/voltage rate to get more clockrate at the same voltage.
    With EDC at 140
    TDC at 110
    SMU at 150
    Curve Optimizer at -15
    i got avg Temp of 71°C on Singlecore and All-Core and
    10% More Score in Singlecore
    10% More Score in Multicore
    in 2 Core i still go much higher.
