Ryzen 7 5800x

[Typsylol]

Hey guys so I’ve been rocking the ryzen 7 5800x for a while and the temps on it are not so great, I’ve seen it hover at the mid 80s and was curious if there was anyone that can share ways to lower the temps. Rocking a Corsair h60 aio to cool it.

An H60? Are you serious!? Well there's your problem.

What Case are you using?

Buy a decent 240 / 280 mm AIO Cooler; and have it inside a Case that has ample room for airflow as well as extra Case Fans.

Even a 360mm wouldn't be too much for 5800x. That sucker gets hot.

Set a TDP limit of 65W or set a negative voltage offset.

5800x is designed to run in the 80s or higher.

PBO, AMD's boost software has two targets, a temp and a power target and it will keep boosting the CPU until it hits one of those targets.

Assuming you're not power limited, your CPU should boost until it hits 88c and then stay around that temp,

The user asked Hallock if "we have to change our understanding of what is 'good' and 'desirable' when it comes to CPU temps for Zen 3." In short, the answer is yes, sort of. But Hallock provided a longer answer, explaining that 90C is normal a Ryzen 9 5950X (16C/32T, up to 4.9GHz), Ryzen 9 5900X (12C/24T, up to 4.8GHz), and Ryzen 7 5800X (8C/16T, up to 4.7GHz) at full load, and 95C is normal for the Ryzen 5 5600X (6C/12T, up to 4.6GHz) when spinning its wheels as fast as they will go.

This.

The 5800X (and/or the 5800X3D built upon it) is the hottest running Zen 3 chip. It's going to run slightly warmer than the Ryzen 9s even because all of its heat, with the same power budget, is coming from one CCD instead of two, and even the 5800X3D (especially once undervolted) might run a hair cooler at times since it has a lower clock speed.

You would want to set eco mode on the 5800X to push it down here. It will get it closer to acting like a 5700X which will still boost about as high in low core loads but will likely boost bit lower in all core loads. It will lower temperatures quite a bit in these (all core) scenarios.

On the other end of the spectrum, if you're using PBO in the motherboard BIOS to raise limits (EDC, etc.), that's likely adding a lot power draw (and heat!) for no real performance gain. I saw that happen on my 3700X. They are already pushed past their most efficient point by default; PBO makes next to no difference in the real world outside making a bar in a graph a tiny bit higher to formally make it look better in benchmarks, but you won't even register that difference in real world use. So unless you have the free cooling to handle it, if it's on, consider turning it off.

These chips almost warrant really good air cooling (or better) at a minimum, like a Noctua NH-D14, Dark Rock 4 Pro, Peerless Assassin, etc.

But these chips are designed to boost when they have headroom. They will spike at low utilization. It's not like chips of old. Intel's pre-6th gen and post-6th gen had a similar change (but it was less extreme) and then later (7th or 8th or 9th gen?) had it tweaked to be more aggressive. Modern generations on both sides are also a lot more dense so the cores are smaller and the heat is coming from a more centralized area. These aren't the quad cores of a decade ago.

I would expect a 5800X could run up into the 80s under an all core load (my 5800X3D [default, no undervolt] does under a Dark Rock Pro 4), and that's not a problem if it does.

[Recuva]

That is a perfectly acceptable temperature. These chips will aggressively self-overclock given the thermal and power headroom. This means that it is typical and by design for chips to reach temps up to 90°C under full load. If your chip is under performing because it is lacking thermal headroom, you could, as others have pointed out, upgrade your cooler or increase case airflow. Otherwise, there is no reason to worry about it, if it does what you want it to do.

This reddit thread could also have some relevance: https://www.reddit.com/r/Amd/comments/jsy8bw/robert_hallocks_response_to_all_zen_3_thermal/

I myself run a 5700x with an nh-d15s that will happily reach temperatures in the high 70's to 80's given a high sustained load.

[emoticorpse]

If those 5xxx cpu's are comparable to 7xxx temps then "hovering" in the 80's would be expected and acceptable during heavy usage. Don't expect to run heavy applications of even semi-demanding work and keep idle temps. I remember where 30-40 was nice idle temps for cpu's, I think those days are gone. Right now at idle my 7900 (non-x) is steady at 49. As soon as I do anything with it, it shoots up to mid-60's. Heavier applications make it reach 79 or so and if I were to leave it like that it would probably break 80. Still, even if it reached 82, I'd feel safe but once it reaches 89 is when I'd start to consider better cooling options and as soon as it hits 93, is when I'd start worrying and know I need to do something.

Zen 3 is where they really started more aggressively using available thermal headroom, so yes it's similar to Zen 4 in that regard.

The temperatures between my 5800X3D and old 3700X are similar to what you describe for your 7900, and I know you had a 3700X before too so you're probably personally familiar with the difference between older Ryzen (pre-Zen 3 in this case) and current Ryzen behavior here too.

And even my 3700X ran warmer than my old 2500K, even though the former had a Dark Rock Pro 4 and the latter had a Xigmatek Dark Knight (decent for its time, but less capable than the Dark Rock Pro 4 of course).

That's why I said the chips of old and the norms of telling how capable your cooling is of old just aren't as applicable, at least to modern Ryzens.

With modern Ryzen, the old rules of using your headroom between your highest temperature and thermal limit is sort of out the window simply because Ryzen will use some of that thermal headroom it if it's there (older chips didn't have the same aggressive boosting algorithms and didn't have as densely packed cores). You used to be able to use that gap to informally measure cooling capability but now being sort of close to temperature limit under all core load isn't a sign of being borderline on cooling. It's only an issue if you're constantly "redlining " so to speak at temperature limit and it's throttling because of it.

So if OP's just hovering in the mid 80s on a 5800X it's not necessarily a problem.
