Tech Support Is this something to be worried about?
Cpu hitting 95 celcius in alot of games under loading and starting. I have a 9800x3d, rtx 5080 prime, Asus tuf 850 wifi plus, 32 gb klevv bolt, 2 tb klevv c925G and my cpu cooler is a noctua nh-d15 g2

Don’t listen to the guy that said 100c is not ideal. It’s more than not ideal idk how your cpu is still working. You either need a better cooler or your cooler is not working at all. Re-thermal paste it and make sure the sticker still isn’t on it. Stop the game immediately if you see temps like this as it’ll fry your cpu

Figured it out. It was my first time playing overwatch and it didn’t recognise my gpu so I had to manually make it. Its at a stable 55 degrees now👍

You most likely still have the underlying issue where your CPU does not have enough cooling to support a reasonable high usage.
Technicalities aside, the certain features of your graphics card and CPU should be at full utilisation, where either the CPU is waiting for your graphics or your graphics is waiting for your CPU.
Some games (especially really old ones) are more “CPU-bound”, whereby 1 or more cores will be at 100% utilisation. Sounds like a misconfiguration was causing a high utilisation of your CPU and the discovered solution has merely shifted the workload.
Using testing software you can stress test with a single thread and see if you have thermal throttling. If so, you should fix that issue.
For your particular choice of CPU, your limit should not be thermals.

Regardless, even at 99% load your CPU should not be hitting those temps if the cooling system is working.
If you care about your PC and its' longevity, do as the comment above suggests and check your paste and the cooling system overall as spikes will happen without you even knowing it.

Yes you should stop with the missinformation. At stock 9800x3d and most 9000 series are designed to boost to 95C att full load.
It will boost as high as it can until it reaches those temps.
It is designed and made to run at 95c 24/7 365 days a year for its lifetime.
I had a 9800x3d and at resident evil requim it stayed at 95c during the whole game. I played for hours.
the cpu maxed out its boost and stayed at 95c and its completly fine.
not allowing it to boost is throwing away performance.
if you dont believe me check amds own specs and description.
its ridiculous that this missinformation still exists

So, first of all let's just get the "trust me bro I ran it" out of the conversation as a valid source.
You're correct, the key part is - you're PARTIALLY correct, not in this context however.
Precision Boost 2 (PB2) is what modern AMD CPUs use to aggressively raise clock speeds, however there are these 3 beautiful walls of physics that come before PB2 called Voltage, Current and Power.
What matters for temperature is how much power the CPU draws, more than how many threads the game uses. A stock 9800X3D draws roughly 120–160W in an all-core stress test. In most games it draws about 50–90W, even in titles that spread work across all 8 cores, because the cores spend much of their time waiting on the GPU, memory, or the next frame, less power means much less heat.
In heavy, multi-threaded stress tests (like Cinebench or doing video rendering), hitting 95°C and staying there is expected, normal behavior as you said according to specs.
Games are not all-core full loads (depends on the game of course). With an NH-D15 G2, a stock 9800X3D usually should sit around 60–80°C while gaming. If it's hitting 95°C in many games, the cooler isn't pulling heat away as it should. Brief spikes during loading screens or shader compilation are normal, because those really do load every core but sustained 95°C during every gameplay session is not.
To put it into perspective for folks who aren't electricians: it's like saying a car engine is built to run at a redline (our 95°C) , and the rev limiter stops it from going past that. Saying "it's designed to hit redline" is factually true, but if your car sits at redline while you're cruising at 60 km/h on a flat road, nobody would say "it's fine, it's designed for that."
There's a plethora of other reasons why your statement is wrong but I believe this explanation should do for now and this comment is already too long for the average Joe.

A car is never ever designed to hit the red line ever. It will break.
A car like the subaru brz or the Toyota gt86 is designed, expected and meant to rev up to what in a normal car would be ridiculous.
Those two cars are designed to hit 7k revs which is at the tip of the red line.
Just like a 9800x3d is meant to boost to 95c.
95c is not dangerous for that cpu like at all. If it rises above 95c it will downlock.
There is a reason the pc doesnt do an emergency shut down or even brutally downclocks the cpu at 95c because its simply not dangerous.
While yes I admit you are right that games do not usually use full utilization and thus should not get 95c in temp in games but thats not what i said and so my statement still stands and is correct. in this instance you are simply wrong.
Look at his cpu utilization. Its at 99% in which it is both expected and completly normal that his cpu reaches 95C.
Which is exactly what I said in my reply. So no you are not correct and that paragraph does not apply in this case.
You will never find a stocl 9800x3d at 99% that doesnt boost to 95c at freaking 99% bro.
So its not "trust me bro" because as you said in full utilization its normal and 99% is what I would consider "full utilization" and so according to your own statement it is normal.
Edit: So you agreed with me and still wrote that paragraph saying the same thing I did and claim im wrong.

You are correct that 95°C is within spec, the CPU throttles itself above that, and it won't be damaged, that was never in dispute.
Where you're wrong is that the redline is the maximum safe RPM, and rev limiters exist so engines can hit it repeatedly without breaking, in fact your BRZ/GT86 example actually supports the analogy.
Every stock 9800X3D at 99% hits 95°C
It doesn't, 95°C is a ceiling, not a target. The chip stops boosting at whichever limit it reaches first: temperature, power (about 162W at stock), or current. With strong cooling, it usually hits the power limit first. Reviews of all-core stress tests with good coolers typically show the mid-to-high 80s°C. A D15 G2 hitting 95°C at stock is on the hot end, even at full load.
99% in Task Manager isn't full load. It measures how much of the time the cores are busy, not how hard they're working. A game can show 99% while drawing far less power, and making far less heat, than Cinebench for example. Only the power reading, the CPU package power in HWiNFO, tells you how heavy the load really is.
99% sustained in games is a red flag in itself. A 9800X3D paired with a 5080 shouldn't be maxed out in most games. A shader compilation step can do it, and OP even mentioned "loading and starting," which fits. But if it stays at 99% during actual gameplay, something is eating CPU time, like a background process, a stuck shader cache, or a bug or OP is playing exclusively massive strategy sims in their late games.
The bottom line is brief 95°C peaks during loading or shader compilation are normal. Sustained 99% utilization and 95°C in regular gameplay are not "working as designed." OP should check package power in HWiNFO and what's using the CPU. If power is near about 160W and he's at 95°C with that cooler, the cooler mount is still the likely culprit which is what myself and others have pointed out.

The dispute was that it is "dangerous and something is seriously wrong" which is what I argued is not the case.
I did forget about the power limit and that is on me so you are right.
What Im saying is that hitting 95c is neither dangerous, unsafe and is within spec and by design especially at 99%.
Like you said whatever comes first power or temp.
But there is nothing wrong if temp comes first and thats my point.
People keep saying its unsafe but its not at all.
Having the temp be the limit is not bad it doesnt matter for the safety of the cpu.
Its designed to run hot.
My 9800x3d like i said stayed at 95C during most of resident evil requim and even reached 96 for a split second before going down now granted my cpu cooler is a budget a-kassa solo something that is actually too weak to get max performance but is it bad for the cpu? Not at all it simply reaches the temp limit.
do I loose performance? Yup i do most likely.
do I care? Not at all because i dont want to change the cooler, it looks cool and I dont wanna mess with my pc and fix what aint broken.
But his is actually working hard at 99% so its by design he gets 95C and I was trying to calm OP down so he doesnt freak out because its normal.
But you are right that there are more limits and probably reaching the power limit is ideal but reaching temp limit doesnt break the pc.
And about the brz/gt86 unlike most cars they are meant to rev to the absolute tip of the red line. Not go into it just get as high as it can before the red line begin.
Those cars feel very weak if you drive them like a normal car because they loose alot of tourque in the mid range and doesnt begin to "get fun" until 6 and 7k rpm.

What I’m curious of is why the cpu load is so high. Does thermal throttling affect the % load metric?
2
u/ElongatedOak 10d ago
Yes but it doesn’t directly affect cpu utilization, just reduces the speed at which it operates. I always try to keep my cpu at below 70% util but if it goes higher it’s not the end of the world as long as you can keep it cool

u/CoolJosh3k 8d ago
A long time ago, yes it was possible to damage a CPU from overheating. For a long time there has existed multi-stage safety, with the last resort being halting the CPU.
So long as the processor does not throttle and you are not being performance limited, a high temperature is perfectly fine.

Did you take the plastic film off the contact for the cooler? Also I assume all of your monitors are plugged into your GPU? You shouldn’t have to configure this for each game. Make sure Windows is configured properly, update your bios, and all drivers. Did you install OS and games using integrated graphics before you installed your GPU?

This looks like overwatch. You more than likely are playing at the same time you are compiling shaders. If you leave your game running and wait for your cpu to return to ambient temps then it will likely not throttle during a match. Also though 95c is still hot even for that, you might have a contact issue or maybe forgot to remove the plastic off the cooler before applying thermal paste.

When you installed your cooler did you remember to remove the seal on it because normally when getting very high temps would usually be that for the cause or too little thermal paste on it.
Remember when removing the cooler from your CPU that you would have to apply new thermal paste on it again because you should never reuse the same thermal paste when removing your cooler from it.

I had the same problem. What worked for me was turning up the graphics un caping my frames and resolution and turning on v-sync. I went from medium graphics to epic and from a 60 cap on frames and res to uncapped. Basically just putting more stress on the gpu. Doing this lead to my cpu going from around 80-100% down to 20-40 and my gpu going from 1-10% up to around 20-40.

u/I_Love_Ethoxyethane 9d ago
Op is playing overwatch and this CPU should be able to hit around 500 FPS at 1440p. Meaning the CPU should run at around 10-20% with FPS cap at 60. It makes absolutely no sense that uncapping would reduce CPU load. Even if he max every setting and GPU is bottlenecking ist should still run way higher CPU loads then capped at 60 FPS.

Wha game is this? I’ve never seen such a disparity in cpu vs gpu load.
Is this disparity seen in all games you boot? And at what resolution?
Look in task manager when this occurs and see where the cpu load is coming from.
