    Been mucking around with my setup, just to experiment, I tried setting one of the CPU to 4600Mhz, and it did hit that target (4599Mhz actually), but wasn't very stable as my other cores ran at 4400Mhz (perhaps a dumba$$ move on my part). Anyway, it was cool to see one core actually hitting that speed though. Now have all cores at 4500Mhz (weirdly, all at 4499Mhz actually) at 1.3375v, RAM at 3334Mhz. Haven't really delve into RAM OC'ing and timing yet, waiting to get my 4x 8GB Patriot Steel Viper 3733's to be delivered by my brother next month.

    4500MHz All-core Manual OC on a 3900X? Yes, that's impressive. Is it CB20 or Prime stable?

    Honestly my cpu the 3600, it's either retard or i have no clue i put an noctua nh-u12a on it the last itineration from noctua with 2 fans and 7 heatpipes, and i said ok this one should cool the lil bastard, my god wasnt i wrong..., so prime95 small fpu - directly 95 degrees+, aida64 81-85, in games 53-60. Honestly can you help me a bit with your temps, guys who have this ryzen 5 3600 cause either im doing something wrong or i dont know, i have no overclock everything is on auto, only the ram is at 3600, the rest are stock everything.
    Btw this is with 100% fans at 2k rpm.

    Can you post a picture of the fan mounted inside the case ?
    The Noctua NH-U12a is only 1-2 deg above the Noctua NH-D15 which is the king of aircoolers.
    So maybe, just maybe you have the fans mounted wrong.
    Have you installed Ryzen master ? Could you share a screenshot of that as well ?

    This 2 are with how the cooler is mounted.

    This one is with 4 screens with PBO on and PBO off.

    And i think i found the culprit :> it's the pbo shooting too much voltage.
    Without PBO 77 degrees on small fft on prime95.
    The settings i use for the PBO is motherboard's limits, which translates into EDC 140A, TDC 95A, PPT 125W, Scalar to 9X, and 200 mhz overclock.
    I think this was the culprit for my temps actually.
    Your opinions?

    No, you have incorrectly installed heatsink. It should have no problem to dissipate stable 115W (Which is btw, your maximum.)
    But you should not use Scalar 9X in situation you have no thermals under control.

    Honestly you can install this cooler in 1 way possible i would say maybe the tim, but i put it exactly as noctua says in a vid on youtube for amd ryzen, 1 bigger dot in the middle and 4 small on the sides.
    Is there something else i can try?

    Remove heatsink and see how did TIM spread. Adjust to improve spread. Target is to have minimum TIM left on both CPU's IHS and cooler's base.
    TIM is not there to create some thick layer. It is there to fill air gaps on rough surfaces.

    Then way you install it matters. Your MB should be aligned with ground and heatsink put on it. Installation while main board is in vertical position often results in bad TIM spread.
    (And much harder manipulation.)

    Lastly is tightening method. Use thin screwdriver, not something with big T handle. (But considering that those Noctuas come with long L screwdriver, you may have hard time finding something adequate, be gentle till the end.) That way you have better control over tightening torque. Small steps are the key here for good spread. With many heatsinks, installation screws have springs and are meant to be tightened fully. (This applies to two screws on base of your heatsink too.)

    Since your cooling comes with protective plastic cover for base, I expect there is no thin plastic film on base that would have to be removed otherwise.

    of course i mounted it with the motherboard horizontally not vertically, the tightening was until the limit of the screws let me i didnt force them il check for the tim when i go home and il take a pic and share it.

    @liviut
    Prime95 new version will use AVX instructions .Your CPU will hit 95c. This is normal ,you need to make adjustments.

    EDIT: just read you turned off PBO and 77c was tempeture this is normal with older Prime95

    Aida64 new edition can use AVX when Stability testing,check under preferences.Also CPU,FPU,Cache,Memory test the CPU can hit 85c+.This is normal when running all same time ,AIDA 64 is a good test for stability.

    Fox2232 makes great points on the mounting but there is just no magic fix when torture test with newest prime95 with AVX instructions,you would need a golden 3600 CPU which are the worst out of all Ryzen 3 CPUs.

    Golden sample would be around 4100Mhz @ 1.23v and you would still hit 90c in Prime95 with just about any cooler.Hell even real water cooling does not help much.
    IF you want I will run Prime95 for you at what your settings are with AIO 240MM and see what my temperatures are.

    List your settings or screen shot all BIOS and I will try duplicate and run almost same test.

    Everytest you se there was done with the latest prime95 and aida64, without pbo 77 is the max on prime95 with pbo 95.

    While you're on the topic of TIM spread.

    With the 3 spot like on the video seems like maybe i shoved 5 degrees or so.
    But still with pbo on if i start prime95 it's 95 degrees and with aida64 85-90.

    Well can you tell me your settings because I would love to try them to get 77c-5c=72c that is amazing with new Prime95 version with AVX on smallFF.
    Actually can you make a video and post it with your settings,you getting such great results you should share with everyone.
    Thanks.

    Here is a video with new prime95 with AVX disabled blend test with all settings hitting 72c also.

    Screens are for bios, i mean photo shoots cause i didnt see any screenshot option on my op gg beta bios, and the video is with prime95.
    Seems like now it's higher with prime95 small fft, and settings are without pbo and 0 overclock.

    https://streamable.com/smmxj i made a 2nd video, prime95 first min after aida64.
    There are some spikes on the aida64 from 70 degrees to 75 and one to 78 or so.
    This are done with the settings from above photos.

    DUDE/Mam you should let Prime95 run so it starts the test on all CPU's at least but if your fine with it .I am good with what you showed.

    It's running on 12 threads i mean that's the max we 6 core can have with smt.
    it's just minimized in case you thought i closed it look on the taskbar
