    I've only had this 3800x a few days. I'm running it stock. Mainly just curious if this is the kind of temps I should expect. I don't like seeing 80s in benchmarks. While gaming, it doesn't get quite that hot. Most anecdotal info I can dig up is on the 3700x. I may eventually buy a 360mm cooler but not wanting to bother for awhile if I can help it. (my massive 5700XT makes mounting more of a challenge)

    I'm using a 120mm size radiator (drawing in ambient)
    Antec P120 case (mediocre for cooling, but not terrible)

    Ambient: 20-22
    Idle: 34-39
    Load, Gaming: 68-75
    Load, Stress test: 81-84

    those temps are perfectly fine. the max temp is 95c and if your're only in the mid 80s for in stress testing then you're well under spec.

    I'm running a 3700x cooled by a h100i pro that sits in the mid 40's even when in "power saver" profile.

    And about the same load temps as you.

    those temps are good.
    Try this change paste use kryonaut and change your fans with noctua nf 12x25 2000rpm (silent) 80 and bellow is possible.

    OK, sounds normal. I appreciate the info. It's just been awhile since I saw temps like this when not overclocking. It's a little spicy but I'll get used to it.

    On a side note, I have to say this Ryzen just plows through games @3440x1440. All the 4790K lag spikes I had have completely disappeared. Seems to be a really nice increase in average frames too. I saw differing opinions of this upgrade (4790k to r7) but I can't imagine someone being disappointed unless they had some amazing silicon lottery i7 running @5+ghz.

    I agree temperatures are normal, if you want some lower temperatures use a CPU offset but not too much where you lose performance
    I like to use + CPU offset for higher clocks and temperatures but below is full run of single/multi Cinebench20 run

    My 3800X with CPU offset and BIOS tweak/bug
    Single Thread-530 score
    Multi Thread -5260 score
    Idle temperature CPU-28°C
    Max temperature CPU-71°C
    Max CPU Core Voltage (SVI2 TFN) reached-1.431v with CPU offset -0.0625

    Settings in BIOS
    MCLK/UCLK/FCLK Synced 1:1:1 1933Mhz ,that's DDR4 3866Mhz
    PBO Manual PPT= 0 actual max limit reached 90.4%
    TDC=0 actual max limit reached 81.4%
    EDC=1 actual max limit reached 7737.7%
    Scaler 10X
    PBO Override 500Mhz

    Temps are good. My 3800X never goes over 71 while gaming and we both have the same low on the range of 68. Also I do not use an offset anymore.

    I just bought a 3800x as well, and I have the same temps. I'm running a Noctua NH-U14A, and I was surprised to see the CPU hit 75 at 15-20% usage. It's made me concerned, but I haven't seen any performance problems from it yet.

    The only game I've been playing is Control, which has hard locked a couple of times when the physics got crazy. I'm not sure I can blame the CPU for that at this time. I need to see how it performs on other games.

    If I were you I would rotate the CPU cooler 180 degrees re-apply paste and see if that does anything. My server is running a 3700X with a NH-U12A and it was to hot and noisy for my taste. So I rotated the cooler 180 degrees and reapplied paste and after that it didn't go above 65 in stress testing and noise went down a lot as well. It might have had a bad mounting without me knowing it. Rotating the cooler and putting fresh paste on it doesn't take that long.

    I added about half an inch of weather stripping down the channel next to my side intake fans (3x 120mm). It's making a noticeable difference. I'm running a stress test now longer than I ever did before and not once has my PWM spun up to full speed. It keeps my CPU hovering at 79-80 running fan at 83%, and I can't hear it. Before, my fan would run full speed within about 3 seconds and running it this long would sit at 84-85. It idled down to 32-33, also new lows I had not yet seen.

    Inspired by that, I may tape off the unused 140mm channels/holes too. So many air leaks.

    I also used a special, really high rpm fan on my old rig's 120mm cooler. It dropped the temps 5-10 degrees, as I recall and it's dead silent. I think I may do that again. 2000rpm, 3000rpm, maybe one of those crazy 5000rpm fans running at half speed. Throw a halo on it to match all the other bling.

    My 3800x with a Corsair H60 is inline with what you guys are saying.

    Want to really throw it a test? Folding @ Home will push you into the high 80's to low 90's. Only program that really got it hot.

    Even though temps are normal and I saw improvement with insulation, I went ahead and ordered a special fan for my radiator (as I did with my last rig). I ordered: Noctua NF-F12 iPPC 3000 PWM, Heavy Duty Cooling Fan, 4-Pin, 3000 RPM And black Noctua rubber, and a phanteks argb fan frame.

    That's supposed to be "the best" performing radiator fan (or one of them). It will be interesting to see how much difference that makes in temps and whether it gets noisy.

    One more 3800x owner here saying normal temps.

    Still, interested to know if that HD fan makes a difference.
    Plus I might try sealing an unused fan cutout from my side panel by your input.

    I removed the cover and put a magnetic dust filter there as I thought it might help GPU cooler draw in cool air, the cutout is right next to GPU.

    Let me know how audible they are. The radiator fans on my EVGA AIO are loud when they ramp up.

    They will be very audible, but about as cool as you can get at 3000rpm

    Even at 3000 RPM they only a couple of dB louder than the 2000 rpm model. And a lot quieter than my VROOOM stock fans.

    What a fantastic fan. With my original fan curve, all the temps dropped 6 degrees, just by swapping to this fan.

    Full speed (3000) drops stress temp under 70, but it would be lunacy to operate this at anything approaching 3000rpm if you like your ears. Even with headphones. But it is more quiet at any given speed than my previous fan, and better at pulling air through the radiator at any given speed. (at least according to temps mapped with open hardware monitor). Meaning you can run this fan slower and do the same work.

    I would say noise-wise, to get this Noctua as loud as my old fan at 100% (1500rpm), you have to spin this up to about 2200rpm (70%) to make it about the same level of annoying. The 2 fans don't sound the same so that's just what it seems like.

    I settled for a fan curve that sits in at 31% most of the time during gaming (~1100rpm) and up to 45% max if it heats up. It's effectively silent and at low speed, cools better than my old fan at 60-95% speed did while being much more quiet doing so.

    I wasted money buying $7 black Noctua rubber to replace the brown. I ended up removing the rubber from the radiator side for a better seal. On the front side, I'm adding an ARGB fan frame this weekend. So, I'm not sure any brown will be exposed anyways, or ever would have been. This "look at me" case I chose. It's like owning a boat.
