Yet another AMD 9800X3D temp question, just give me some peace of mind please i beg you.
Posted by Electrical_Car6942@reddit | buildapc | View on Reddit | 44 comments
i bought a 9800X3D and it came yesterday, Using HWINFO looking at the CPU(tctl/Tdie) temps, package sits at 50 to 55 degrees idle and the CCD at a stable 40 degrees, while compling shaders for monster hunter wilds CCD went to 82C max, the weather is about 25 degrees since it's getting close to winter.
But i worry about summer, my cooler is the Master Air MA824 Stealth from coolermaster, i repasted like thrice already, even risked it all by tightening it kinda hard (i fully regret being this stupid), but to no avail, did i do something wrong?
the third time i repasted i just tightened it lightly but enough to be firm.

If you're below 95C, you're fine. Stop worrying.
Moscato359@reddit
I'm sick and tired of people who see numbers under 90, and worrying about it
There are like 15 of these a day across the various tech subreddits
TeamChaosenjoyer@reddit
When did people become so tech illiterate like recently it’s like they just have glue eaters just buying parts without doing any research like I saw one “should I upgrade my 3080???” Fucking why lmao
Moscato359@reddit
The easier computers are to use, the less people will learn about them
It's like kids with an ipad that don't know what a filesystem is
"should I upgrade my 3080???"
Sure, if you are buying a 5090. Otherwise no. And oh, the 5090 is unavailable, so no.

Thing is if this was intel people would be saying it’s cooking itself and all that bullshit. Why don’t we say this about ryzen? I mean I switched to a 9950X3D from an i9 14900KF. I have to get used to 46c idle temps when the intel idled at 27 and used about 9 watts at idle. This uses 35 or more at idle with ALL cores parked/sleep.
flakk0137@reddit
Which one do you like more, performance wise ?
crazydavebacon1@reddit
Honestly the 9959x3d is better so far.
Jeep-Eep@reddit
Intel chips are a mess so folks are kind of right to be extra paranoid.
MarxistMan13@reddit
I don't know why 46C idle temps would be at all concerning. Idle temps are completely meaningless below like 60C. Doesn't matter whatsoever.
My 9800X3D idles between 4-10W and 44-52C. It actually uses quite a bit less power at idle than my 5800X3D did.
Electrical_Car6942@reddit (OP)
in the past it was AMD that got all the people laughing at it's high temps if i'm not wrong tho. but it still was a surprise to me that cpu's nowadays idle at such high temps.
psimwork@reddit
All of this has happened before, and all of this will happen again.
Intel got laughed at with high temps for the ~1GHz Pentium3 era.
AMD got laughed at for their high temps for the final Athlon XP's.
Intel got laughed at again with high temps for their later ~4GHz Pentium 4's.
AMD got laughed at for the entire Bulldozer line.
Intel got laughed at for being stuck on their 14nm node for the 6th gen until 11th gen (and especially 11th gen).
Intel is now being laughed at for the 13th/14th gen.
What does all of this have in-common? Cranking the clockspeed to overcome shortcomings in shitty architecture, resulting in more power consumption, resulting in higher temps.
Moscato359@reddit
"Thing is if this was intel people would be saying it’s cooking itself and all that bullshit."
AMD and Intel both have excellent thermal protections built into their chips.
Intel had some screwed up *voltage* issues for years.
Sensitive-Rock-7664@reddit
It's objectively true that when measured equally, the amd-CPUs end up cooler at every price point and performance tier if you compare 14th gen intel to am5 amd CPUs
psimwork@reddit
Some would, perhaps, but not me. I've been saying since like 2017 that it's basically impossible to cook a CPU via heat alone. It's VOLTAGE that cooks CPUs, and Intel's issue isn't the max temperature - it's that they wanted to absolutely crank the clockspeed to make up for their architectural shortcomings and to do that, you have to increase voltage. There's really no way around it.
My other issue with them is again - not the max temperature, but the 250+ watts that it consumes under full load.
Dysan27@reddit
It's because alll the old knowledge says to be worried.
Even just a couple gens ago running too hot for too long was bad.
It's only the last couple gens where they tweaked the OC/Turbo algorithms again to target 95c. And that knowledge isn't completely know yet, as it goes against everything before it.
Moscato359@reddit
If people used search, at all, they would know the answer to this, but instead there are over a dozen new posts about it every day
psimwork@reddit
In fairness, back in the day (circa 2003 or so) you could literally pop an AMD CPU at like 65C+ and there was no built-in thermal protection design.
But yeah - Intel has had thermal protection (I think) since the first Pentium IV's, and AMD added it with their first Athlon 64's.
Moscato359@reddit
AMD went into hard thermal protection mode with the 5000 series, where they added over 1000 thermal sensors across the chip, allowing them to boost closer to the actual real thermal limit, by being more precise per core

Seasonalocean@reddit
Yea i undervolt my 9800x3d, it was 95c with cinebench, now at -35mV, max out at 80c with same clocks.
Wooshio@reddit
Why not try to undervolt? It's very simple to do on AM5 with the curve optimizer and almost every 9800X3D will do -20 wit no performance loss. That alone would bring you down about 10c on load. Just start at -10 and go from there.
Seasonalocean@reddit
My cpu max at 95c on cinebench with a 360 AIO, and idle around 40-45c. If I undervolt by 35, max is 80c in cinebench.
Swqme@reddit
is PBO better than setting a static limit? for example a 4900mhz @ 1.2v or something or would PBO yield better results
aragorn18@reddit
The maximum operating temperature of that CPU is 95C. So, you still have 13 degrees of headroom. Do you expect your room to heat up by 13 degrees in the summer?
I don't know a lot about that cooler, but it looks like it should be pretty good. Any decent dual-tower cooler should be enough for that CPU.
Electrical_Car6942@reddit (OP)
In the case it hits 95C, it does throttle down right? i didn't think about that either, if it does then i guess i'm paranoid, my previous cpu i7-9700k worked at 37 to 40C idle tho so that's why i am this worried, though i've hit plenty of 97C on that i7 while gaming
HurricaneFloyd@reddit
You can turn on a modern CPU with no heat sink at all and it will just run at very low clock speeds to reduce heat. Int eh event that throttling doesn't reduce the heat enough the CPU will immediately shut down. If your CPU is not getting hot enough to throttle down then you are good to go.
psimwork@reddit
Yes and no. It doesn't throttle down, but rather it just limits boosting.
You basically cannot damage a modern CPU via heat alone.
Wanderson90@reddit
Wanna bet?

blueiron0@reddit
cpus have come a long way since 9000 series. They are designed to try and hit the 95c now rather than stay at a lower, stable temperature. They're auto clocking themselves up as much as the voltage and temperature will allow. They protect themselves though and will clock back down when getting too hot.
The better cooling you provide it, theoretically the more headroom it has for performance.
Electrical_Car6942@reddit (OP)
Thanks guys, i guess i will just enjoy the technology jump from my 7years old, now retired i7-9700k.
Schnitzel725@reddit
not sure if it'll help but try going into bios > pbo > curve optimizer > negative maybe 15-20. Seemed to help lower the temps on my 9800x3d when I did that.
Although not sure how much of it was partially because i swapped from a Hyte Y60 to a Fractal North XL (due to the Y60 cooking my gpu)
Moscato359@reddit
These CPUs are designed to operate at 95C 24/7, 365 days a year, for decades
Dudi4PoLFr@reddit
The limit is 95C for the 9800X3D so don't worry you have some spare room. Also are you using Curve Optimizer? I'm running my 9800X3D at 5.45 GHz all cores and -32CO, it gives better performance with even lower temps.
Dilanski@reddit
You're probably fine, it's functionally a postage stamp sized 250W space heater, it's going to get warm.
For your own peace of mind, what's your CPU fan curve like, and what's the airflow like for the case. If those are good, then don't worry about it.
Raitzi4@reddit
Thermal contact might not be good. Ptm7950 costs you like 10 dollars. That will fixt that. Also you could do basic pbo undervolt.

“Designed for a lifetime at 95 Before anything else, let’s be clear: All of the quality analysis for Ryzen 7000 series desktop processors was done at 95 degrees Celsius. The chip is engineered to live its life at this temperature with no detriment to longevity or reliability. In fact, this is the same design target we’ve had for a number of product generations, but it has not been until the Ryzen 7000 series that the platform has had access to a level of socket power that makes 95 C the temperature that delivers the most performance during multithreaded workloads… “
bufu619@reddit
Temps are normal, stop worrying before you damage something yourself lmao
RazeZa@reddit
should be normal. Mine has the same temps more less. 50ish under load or light load and 80 maybe 85 on higher load. I also live in Asia where ambient temperature is higher.
ecktt@reddit
You should be sage, though, that's a pretty high temp for that style cooler. I am not familiar with that exact cooler but a friend with a 9800X3D gets mid 70's with a thermalright Peerless assassin. We live in the tropics for context.
How is the air flow in the case.
ime1em@reddit
maybe you have bad airflow case?
Warskull@reddit
CPUs these days run a bit hotter than previously. 50-55 is not entirely unreasonable for idle, especially if you have a higher ambient temperature.
As for the CPU temp, there was a big shift in CPU philosophy and they tend to run hotter now. These days they try to boost your CPU up to higher temperatures. If you are just sitting at 65C under load that is performance they could be squeezing out of the silicon and giving it to you. So anything under 90C is normal.
MarxistMan13@reddit
AM5 CPUs can run warm if you don't have an offset mounting kit. Available for some coolers from their manufacturer, or nearly all of them from Thermal Grizzly. The CCD is mounted low on the CPU, which means center-mount coolers (all of them, basically) miss the actual hotspot on the chip.
Though none of the temps you mention are at all concerning.
ArdentGuy@reddit
Monster Hunter shaders compilation always turned up the heat on my CPU compared to all other games. It’s just an unoptimized piece of crap. While playing MH Wilds for hours, my CPU would never hit above 65 degrees with a Peerless Assassin Mini in my mini ITX build.
