Ryzen 7 9850X3D high temps (85–95°C gaming) — normal or is something wrong?
Posted by Trick-Fisherman3562@reddit | buildapc | View on Reddit | 82 comments
Hey everyone,
I’m having some concerns about my CPU temps and wanted to get some opinions.
I recently upgraded to a Ryzen 7 9850X3D, and I’m seeing what feels like pretty high temperatures. At idle, it sits around 50–60°C, and while gaming it goes up to 85–95°C.
Specs:
GPU: RTX 3080
CPU: Ryzen 7 9850X3D
Motherboard: ASUS X870-A
RAM: 32GB
Cooler: NZXT Kraken Elite 240mm AIO
I’ve already repasted and reseated the cooler, so I don’t think it’s a bad mount, but I’m starting to wonder if something else is going on.
What’s confusing me is that my previous CPU (Ryzen 5 5600X3D) ran much cooler under the same setup.
So I’ve got a few questions:
Does anyone else CPU run this hot ?
Could my AIO be the issue, or is 240mm just not enough?
Should I try undervolting, and if so, what’s the safest/easiest way to do that on this chip?
Any advice would be appreciated 🙏

That's too high. My 9950x3d never tops 60c on even the most challenging tasks.
J0K3R868@reddit
How do you get your temps like that, is your room naturally cooler? I'm running a corsair titan 360 LCD, with arctic mx-7 paste and my games constantly get to around 80° and I just have a 9950x
albinosnoman@reddit
Are you overclocking the pants off your chip?
J0K3R868@reddit
No, that's how it ran stock when I built it
albinosnoman@reddit
Interesting. With or without PBO? 80C° is close to the upper limit of the absolute heaviest bench testing on mine. Like the other guy said most normal taks and gaming won't usually exceed 65C°. You're using a liquid cooler? Even with a good air cooler you should still be able to manage the thermals on a 9950X3D much better than that. I find this curious.
J0K3R868@reddit
Top mounted rad/exhaust fans, 3 intake on the side, 1 exhaust on the back and bottom
albinosnoman@reddit
What do the temps in your loop look like? That's usually a pretty good indication of whether or not your exchanging heat well or not.
J0K3R868@reddit
Like all my components?
albinosnoman@reddit
Negative, I'm asking how hot the fluid is inside your coolant loop. There should be a temp sensor in your pump you can read with iCUE or HWInfo64. I'm running an H150i in my other system which should be fairly similar and my fluid temps are usually around 35-40C° depending on the time of year. If I ramp up the fan curve the fluid temp drops fairly quickly but doesn't get too low as long as there's load on the CPU. For example if I'm at 40C° and ramp up the fan curve I might get down to something like 36-38C° but it won't get much lower since new heat is being dumped into the fluid from the CPU.
J0K3R868@reddit
Oh, I've never monitored that, I'll redownload icue link once I get home from work and I'll check under load and at idle
albinosnoman@reddit
Yea iCUE rubs some people the wrong way but I haven't had any issues with it for about the last year or so at least. Anyway I'm curious to see if running iCUE somehow fixes pump/fan behavior in some way but if not it'll be helpful to have the sensor data. You should be able to run everything without it though and then just pull the sensor data from HWInfo64.
buddymanson@reddit
Strange. I have the same cooler and my 9950x3d tops at 53c when gaming using the quiet preset on all fans except AIO(balanced). What case are you using?
J0K3R868@reddit
Corsair 3500x
buddymanson@reddit
I have the same case. Maybe use a more aggressive fan preset in iCUE. Though my guess is your CPU is running at higher clocks when gaming than the X3D version, which could explain the higher temps. Then again, my 13900k that all uses a 3500x & Titan 360, never goes above 60c when gaming.
J0K3R868@reddit
Yeah I was seeing that those temps are normal for my CPU, I don't use the icue software tho
buddymanson@reddit
The default preset without iCUE is balanced so getting iCUE probably wouldn't help your temps much anyway. The 9950x just likes to run a little hot.
wivaca2@reddit
I have it in a Corsair 7000x case with the Titan 360RX LCD radiator pushing out the top, 3 intake fans in front and pulling out back, and even an RTX-4070 in it. Half the time the fans don't even run, even in game. No overclock.
Room is currently 76F. Current temp is 63C with a CPU-heavy game, Adobe Illustrator, Bambu Studio (slicer), Word, Outlook, Teams, and about 20 Chrome tabs open.
I just left the game and temps already down to 52C. AIO Coolant at 40C. When the room is cool (about 65F in winter) the CPU hangs around 45C when not gaming.
(I misspoke earlier about the H150 - that was in my old machine.)
J0K3R868@reddit
Also running it with a 5080
J0K3R868@reddit
Ohh, I have a smaller case, I have the 3500x
MrSethles@reddit
Exact same CPU, cooler, and temps C:
AgreedToAPoint@reddit
For a CPU if this level the 240mm aio should do okay but you're definitely running a little bit too hot so insure that the peel is off (Sometimes if you paste it it can be a little hard to see) of your aio and honestly a 360mm would be better and overall don't undervolt because you'll lose performance and it won't be worth the money you paid for it but that is a spicy chip most of the time so if you can even drop it to 60 or 70 that would be way better
AgreedToAPoint@reddit
ALSO INSURE THAT IT IS FULLY MOUNTED AND SCREW DOWN REALLY REALLY TIGHT BECAUSE THAT CAN BE A MAJOR ISSUE
beirch@reddit
Ensure.
Insure is something you do to your car.
AgreedToAPoint@reddit
Check ur account stats brother...
beirch@reddit
My account stats have nothing to do with your ego being too big to accept a simple correction.
AgreedToAPoint@reddit
No brother... You are on here way too much just give it a rest ik ur at least 40 man please give it a rest it's not a big deal
beirch@reddit
You're right, it's not a big deal at all so I don't understand why you're getting all flustered.
Also, just fyi you have no idea what you're talking about regarding CPU tuning at all. Undervolting won't reduce performance; quite the contrary, it will increase performance.
Switching PBO to manual and adjusting curve optimizer with a negative curve optimizer will increase performance while reducing overall temps.
In addition to that, undervolting AMD CPUs functions as an overclock (just like AMD GPUs), because you're lowering temps and increasing headroom, giving the CPU more room to boost higher.
Maybe don't give advice when you are this clueless.
AgreedToAPoint@reddit
Listen bro I'm not gonna play into ur little redditor games like this I hope you have a good day brother
Thecurvyguy@reddit
Wait he’s right about undervolting tho.
neddoge@reddit
And he's right about dude being a little soft dork ass about being corrected.
Orddenn@reddit
Guys, I'm trying to read about this person's high temperatures and you two are distracting me.
Orddenn@reddit
You both need a snickers
Trick-Fisherman3562@reddit (OP)
Yes I did it I’ll do it again just cause and also the pump tubes are facing up should I put it down or it’s fine?
AgreedToAPoint@reddit
Usually orientation doesn't matter a whole lot but if you can attach an image it would help to better understand your question
Trick-Fisherman3562@reddit (OP)

ShaftTassle@reddit
That’s probably the issue - flip it around so the tubes are at the bottom.
The way you have it allows air bubbles to be trapped at the top and makes in harder for the fluid to circulate.
Trick-Fisherman3562@reddit (OP)
U mean flip the radiator or flip the circle screen so the tubes are facing down ?
ShaftTassle@reddit
Both.
AgreedToAPoint@reddit
So I would recommend putting the tubes in this case facing the right or bottom and it should drop the temps down to like 70 but also in your bios make sure your aio is running at full speed because it should be on a aio but it's not automatically like that
Trick-Fisherman3562@reddit (OP)
In my NZXT CAM it says it’s running 2300-2600 RPM is that good or
AgreedToAPoint@reddit
Likely so but double check your fan manufacturers official web page to find out if you're not using the fans that came with the AIO and also what is your CPU idling at right now
AgreedToAPoint@reddit
It should be at like 20 to 40 which I red your post again and it's definitely well over the ideal temp so just check and like I said and get back to me
Trick-Fisherman3562@reddit (OP)
I just checked the website the fans they came with are static pressure fans but I don’t use em and the fans I put on the radiator are designed with decent static pressure performance
Trick-Fisherman3562@reddit (OP)
I don’t use the fans if came with I got lain li fans on it and it’s connected to the controller and my cpu is idleing 57
albinosnoman@reddit
Your CPU idle is way too hot. Zen5 chips should be idling closer to 45C°
AgreedToAPoint@reddit
Make sure they're static pressure fans please and at this point I really doubt it if you're using non OEM fans with the AIO but just look and make sure because you need those types of fans for aios
AgreedToAPoint@reddit
Check their website and look at the model and just max the AIO fans out
inevitably-ranged@reddit
Jayztwocents has a great screenshot/meme of showing the orientations but apparently I can't comment photos here which is mega lame

Diedead666@reddit
Iv attached coolers upside down and works fine lol
ImStillExcited@reddit
Undervolting does not lose performance, nor is it dangerous.
Undervolting my CPU was one of the best system "upgrades" I've ever made article. But you can google it, and find the same answer.
Lewdeology@reddit
Doesn’t help that the 3080 runs hot as hell too.
LegitimateBeing1044@reddit
I find the idle temperature surprisingly high. I cool a 9800x3d with an air cooler (Phantom Spirit 120 EVO) and the temp is 39C during idle. Gaming at 60 maximum. I would suspect your cooling setup.
Scitzofrenic@reddit
Somethings wrong. Thags way too high. My 9850x3d doesnt touch these temps
its_all_4_lulz@reddit
Are you running Fan Control?
I installed fan control and it thought my AIO was a fan, so only ran it at 20%. I was getting temps like this. After setting it to a constant 100%, I only hit 80 if I’m purposely benchmarking.
Trick-Fisherman3562@reddit (OP)
No what is fan control and where do I look for to see how fast it’s running also I have nzxt cam and signal rgb will those cause problems if I install it
its_all_4_lulz@reddit
If you’re using Signal to control fans, iirc there’s a whole section for it, then this might be the issue. I have signal too, just running lights, and turn everything else off.
Fan Control is just a free program that lets you create graphs to tell fans to turn on when certain temps are reached. You have to determine which fan is which, as it will show you a bunch of them. Watching the temp rocket up as I turned fans down is exactly how I determined which “fan” on the program was actually the AIO pump.
Ok_Figure_6442@reddit
Check io-die soc tamp>50C
GatesTech@reddit
The 9850 is a hot mess, try some undervolting. Paired with an Antec Vortex View 360, my idle is 48–55°C, while gaming averages 60°C, with some spikes to 70°C when it is shader loading.
Ebytown754@reddit
Way too high. Even with a 240mm. I have a 360mm and I don’t think I’ve seen my 9850x3d over 75 gaming. It usually in the 60s.
wivaca2@reddit
Same for 9950x3d.
horizon936@reddit
My +200mhz -25 CO PBO'd 9800x3d idles at 42-45C and sits between 52C and 58C in most games. It obviously hits 90C during shader compilation if I start a game right after an update, but 62C is the most I've seen during actual gameplay, ever.

Your temps aren't normal.
8000RPM@reddit
Rotate your pump head 90 clockwise and your entire radiator 180 so the tubes are down not up. Also flip your fans so they push air through the rad outside of the case.
albinosnoman@reddit
To illuninate this a bit the reason you want this is so the pump isn't fighting gravity as much and doesn't get cavitation in the pump inlet which is often what creates the horrible pump noises people hear. The fans being the way they are now would only make sense in a push/pull set up but I doubt that's what's happening here so the air in the rad isn't benefitting from the static pressure in the fans which is what effectuates heat transfer in the radiator. Flip the fans or put them on the other side of the rad if you want to keep them as intakes.
Trick-Fisherman3562@reddit (OP)
So flip my fans on my radiator to have air coming out the case and put my tubes facing down right https://imgur.com/a/FEfLwK4
albinosnoman@reddit
Yea you want the pump rotated either 90° or 180° so the inlet and outlet are on the right/left or on the bottom and then the rad itself you want the tubes on the bottom so you're not pushing air that can collect in the top of the rad. For the fans, yes you can flip them around, or if you want them as intakes just put them on the other side of the rad if there's room for that.
MuzanSama98@reddit
I had the same situation when i got my 9800x3d tried undervolting and it doesn’t go above 75c even under constant full load so try undervolting your chip
Xp3nD4bL3@reddit
What's your fan/pump setting on bios?
Trick-Fisherman3562@reddit (OP)
https://imgur.com/a/CHXImY3 here it is what should I change ?
Xp3nD4bL3@reddit
The curve looks OK, but I see that you have chasis fan? Or the chasis fan is connected to a hub? make sure all your chasis fan work as they are essential to reduce overall heat in your case
Soggy-Airline@reddit
Get a Thermalright phantom assassin… you’re good to go.
No-Actuator-6245@reddit
Is your AIO setup as an exhaust or intake in the case? Does the temperature stay the same even with the case side panel off?
A 240mm AIO is no better than a mid range air cooler. If your AIO is setup as an exhaust and especially if the only exhaust then all the hot air from your 3080 is being used for cooling the cpu via the radiator. My old 3080 although it ran at reasonable temperatures dumped a huge amount of hot air in the case, improving case airflow noticeably helped other temperatures when there was high gpu load.

Trick-Fisherman3562@reddit (OP)
Side panels off stay same temps
albinosnoman@reddit
Side panel wouldn't affect it much if your rad isn't moving air or fluid properly. Are you able to put the fans on the other side of the rad or flip them around? You're not going to be getting as effective heat transfer with the current orientation of those fans.
crazybull02@reddit
You've mounted it wrong, tubes on the fan need to be in the bottom or mount those fans to the top of the case. Right now you're using a water pump to move air and they don't do that well.
enso1RL@reddit
Too hot. I think either the AIO is mounted incorrectly or something is wrong with it
Atazwi-_-@reddit
I have a 9950x3d in my pc with a 240mm AIO in the same case lol. I suggest setting up a push-pull with more fans in the back. At 100% load max temp was 82 during normal gaming, about 68
jordansaul@reddit
You should only see these temps while building shaders when installing a new game or after driver updates & should only last a minute or two . While gaming high seventies at most, maybe 80
BNSoul@reddit
Too hot, even if it is just a lazy factory-overclocked CPU. On the other hand, my 9800X3D runs around 39-41c with per-core CO at 5350 MHz.

BuyCompetitive9001@reddit
Seems hot to me. Especially if you are GPU bound. I have a 9800x3d and it only gets into the low 70s when GPU bound. Often it’s in the 50s when I cap frame rate.
What are you playing and how are you playing it?
Trick-Fisherman3562@reddit (OP)
Mostly play cs2 and apex recently in cs2 it goes to 87 to the 90s (steam 4:3 1440x1080)
