Question Ryzen 9800X3D idle & gaming temps ?

Good evening, folks! Was wondering if anyone else has encountered this phenomenon.

The idle temps on my Ryzen 9800X3D are anywhere between 41-45c in desktop, which I know is typical for this chip. When gaming, however, my temps will only shoot up to 49-51c, while gaming at 2k 144hz with absolutely everything cranked to the max (no upscaling, etc.., full load) currently running a -30 CO, CPU is on a
Cooler Master MasterLiquid 240 Atmos. Did i hit the silicon lottery? Also, kind of wish my idle temps would be lower...

Is this normal? Temps were confirmed in both adrenaline, and hwinfo.

Thanks! :)

Well, that depends on a game. GPU bound games won't utilize CPU as much and in turn, have lower impact on CPU and it's output (including thermals).

To test your cooling, download and run Blender bench,
link: https://opendata.blender.org/

Choose CPU render and look what kind of temps you're getting when all your cores are put under heavy rendering load.
If you get ~86.5C during bench, then your chip and cooling is considered normal. If you get higher temps then either your chip or cooling is the issue.

Thanks! Will check it out and circle back here with the results.

It only went as high as 48.5c...

I do have a -35co negative curve on all cores. Could it be that, or something else?
Probably not . But try CB23 again with curve -15 or all PBO disabled. Did you on EXPO memory profile in bios? Show also cpu usage and frequency during cb23 test.
Try reset bios to default and set only EXPO memory profile on. Then run CB23 test

I do have PBO on auto, -35co, will tune down to -15 and put PBO on MOBO. memory is on EXPO, running at 6000 MT/S. Will change curve, adjust PBO and test again. Will post after. Thanks.

Got a 23340 changing negative curve to -15 from -35 and setting PBO to motherboard from auto. Temps were at 81c at their highest. Idle is now a flat 45c, is that good? My last 9800x3d was idle at around 38c, was on a different AIO, and was a different 9800x3d chip. Any way to get better idle temps, or is 45c ok?

Now everything seems to be as it should be:) Don't pay attention to the idle temperatures, they are perfectly fine and a waste of your time. Enjoy playing:)

Thank you. OCD is just getting the best of me. I know 45c is fine for idle temps for the chip, but it was still nagging at me. Granted, the 37c I was getting before was on a different 9800x3d w/ a different aio in a PC i built myself, but settings were all the same.

Is this just silicon, or a different chip and AIO, or is there anything else I can do to get better Idle temps?

Thanks again.

Even running a CPU bound MMO like new world, CPU Utilization won't go over 40%, GPU at 100%, and temps are at 48c running it at 2k, with setting all cranked up. Is this chip really just this good? I cant find any games to really push the CPU.

I told you these idle temps are fine, you dont have worry about it. Differences in temperatures may result from different chips, but also from many other scenarios, e.g. running processes or applications in the background. You would have to compare them in exactly the same conditions. It's a waste of time, your temperatures are fine

Thanks again. This helps put me at ease (a little) lol. Cheers! 😎

There is no ideal idle temp. Since idle temp vastly differs by ambient temp, cooling solution, fan RPM, fan size and fan amount. (Dust too.)

Hence why, there are no idle temp charts in component reviews.
E.g just look your CPU review temp chart i linked above.

Note: You will never get lower temps than ambient temps. Since PCs are cooled by ambient air.
Also, idle temps doesn't matter because even the smallest cooler can keep CPU/GPU near ambient temps. What matters, is under load temps, since there you can see the effectiveness of your cooling solution (usually balance between noise and temperature target).

E.g in my Skylake build (full specs with pics in my sig), idle temps currently are:
* 27.2C - ambient
* 30C - CPU (i5-6600K)
* 42.7C - GPU (GTX 1660 Ti)
* 41C - MoBo chipset (Z170)
* 49C - OS drive (970 Evo Plus 2TB)
* 35C - OS backup drive (960 Evo 500GB)
* 33C - data drive (870 Evo 2TB)
* 36C - data backup drive (MX500 1TB)

But these values of mine will tell you 0, since you do not have the same ambient, components and airflow setup as i have. Moreover, i have 91W TDP CPU while you have 120W TDP CPU. So, your CPU inherently runs hotter, even on idle.


Now, if you truly want to get lower idle temps, then you have to eliminate ambient air as cooling method and go by the route of cryogenic fluid cooling (e.g LH2 or LN2). These cooling methods are used with CPU and GPU record breaking runs (e.g highest stable frequency). If you have the money for it and OCD to push you along, no-one isn't stopping you to use the same cooling for your chip.

Thank you. So, I guess 45c Idle isn't bad considering Cinebench R23 didn't go over 81c and gaming, no matter what I throw at it, won't even go over 60c.

I have 7800x3d and in games like Cyberpunk or Spiderman ( cpu demanding games) i have around 70C and 84C in Cinebench. But 7800x3d its hotter chip than 9800x3d, besides, I use cheap air cooling. 9800x3d is better than my processor so usage in games is probably lower which probably also has an impact on lower temperatures. If you don't notice any performance issues in games and your CPU clock speed is close to max during the game, it looks like everything is fine.

Thanks. Watching cyberpunk tests @ 2k on a 9800x3d, I notice the power consumption is way over 70w, but I can't get mine to go over 40-50. Any idea why? Can't really get power consumption to go over 40-50 on anything, while I see videos of similar games pulling 70-90w. I've even removed my -CO and set everything to stock. Wondering why it's not pulling more power. Feels like I am losing performance somewhere.

Try updating your BIOS and chipset drivers to the latest versions. Check if you have any power saving features enabled in Windows (set power plan to performance). If you have the latest BIOS, reset to factory settings and enable only EXPO without a curve and with PBO disabled
