9800X3D, hotter than the first day, pulling more wattage?

[Ene]

I have an ALF3 360 AIO and my 9800x3d temps are also high, 50 idle, gaming around 70+ and 90+ in CB. I haven't figure out yet what is the problem.

Tried to take of the AIO several times and reapply paste still no improvement.

 

[Pets4Ever]

Ah i see - then yeah rad up front makes more sense in that case.

I was thinking exhaust out the top, with the front fans remaining as intake.

 

[_roman_]

There is nothing wrong with mx-6, great paste; there are reports of counterfeits being sold by resellers however.

Your opinion. Are you paid from Arctic?

nothing wrong --- but coutnerfeits

Those arctic FAKE posts were posted in 2025. I bought my paste in 2023 where no one was talking abuot fakes. The paste was trash in my point of view

Of course ARCTIC sold me themself a fake one, right?

That totally works - just put the AIO up front then for the coolest CPU temps.

Theoretically, I would expect the GPU to be more heat sensitive given that it consumes 300-320 watts while the CPU has never taken more than 140 so far. Of course, right now the GPU benches cooler than the CPU...

Well that's depressing to hear. What is your case and fan setup? Ambient temps?

Oh, and what motherboard?

What framerate do you run at, and what temps on your 9800X3D with that thermalright?

Actually surprisingly not -- the GPU heat dissipation is much better than CPU, and it's much less sensitive to the 1-2 C increase.

Anyone who'se ever had a CPU and GPU in the same water loop can attest to this - a GPU can happily run with 40C water and never sail past 65C, while cpu will be boiling at 100C.

Those are some serious temps. Just think, playing a game on your PC is an easy load for it. Imagine if you gave it real work.

To be fair, I think there is something seriously wrong with Helldivers 2 in particular. A few patches ago they allowed the AI to "do more" and they predicted a small hit to CPU performance. In practice, it tanked a lot of people's performance by 20fps but without fully utilizing system resources. ArrowHead chose to use an outdated engine because they said they were familiar with it, but in practice they seem completely lost when it comes to optimization.

As someone pointed out on Steam, I don't think they made the AI any smarter, they just allowed them to enter an action queue more frequently. They just do more dumb things faster lol

120MM AIO Intake - test - 10 min Cinebench run - dual fan push pull @ 1600 RPM (same profile as the Thermalright Phantom Spirit Evo, same fans), Thermal Paste: Kryosheet.

Clocks pegged @ PBO 5425 -20 CO - max temp 84.7C

House ambient temp - 72-75F - AC had just kicked on.

With a 360MM AIO you should be frosty. This is a $35 Thermaltake AIO. So to @JustBenching 's point - 240MM AIO is more than enough - it's definitely a heat dissipation problem. You can see the slim 120MM just barely get overwhelmed at 140W from 75C to 85C - but even then not really.

Very nice temps! Do you have PBO enabled? Maybe I'm having a smooth-brain moment, but is there an AIO and a tower cooler in your case? I'm a little confused.

I re-flashed my BIOS tonight and enabled EXPO but not PBO. I am idling at 45°C. Not as low as the first day I got it, but pretty close. I could believe my ambient temps are 5° higher. This is a far more reasonable result so far. I haven't taxed it yet though.

PBO enabled +200 - got rid of tower put in the aio for science.

Idle at 45 is fine. I also idle at 45ish. Amd idles high - load most important.

Wow, and I just realized you case is SFF that's pretty darn good.

If I don't get acceptable temps with the new AIO (better not hit 90 in CB), I'll probably be looking at a different case. It's a well made case and I like that it looks unassuming, but my thermal footprint has changed a lot. The build I bought it for was a i5-6600k and a GTX 1070. That's a combined TDP of 240Watts for the CPU and GPU, now I've got a 9800X3D and 4080S which is a combined TDP of 440W if we're being conservative, but is higher with CPU boost clocks as well as the faster ram and the M.2 drives, not to mention how Nvidia recommends a much higher PSU for power spike requirements.

I actually just did a build in a fractal north for a friend and I really liked it. Only a 240mm up top tho... and if you have front intake rad your GPU clearance is actually not great.

Meshify 3 is also nice but not sure about that front panel.

 

[rv8000]

That would explain a lot. Are your individual core temps similar to your Tctl/Tdie temps? Because mine have been at least 10 degrees higher from the beginning.

More info on my HD2 performance:

* 9800X3D with 4080S
* 1440p resolution
* uncapped frames
* ~90 fps average, more on the ship
* 4080S draws 300W most of the time in this game, sometimes 320

When I get home, I'll capture some data with HWINFO

Got a chance to run some HD2. Average core temps were 66c, average package temp was 73c, peak package temp hit 95 ONLY when dropped from the hellpod loading into the mission, never came close at any other point. Max ppt hit 133w with no PBO and stock cpu.

So cores and package were below 73c for the entirety of a 33m missile launch mission. Only running a single fan on my NH-D15 at max rpm (for memory cooling).

"Degrading thermal performance" (without settings changes, anomalous loads, etc.) is usually
-dust and/or hair and/or e-juice and/or tar buildup on/in, cooling fins and/or fan blades and/or intakes.
-TIM migration from thermal cycling (I've watched it happen in 'real-time' on Vega GPUs and my 5800X3D CPU; both w/ AC MX4)

Wow. You're making me wonder what in the actual F I'm doing wrong w/ my 5800X3D on a 280mm AIO. IIRC, I used TF9* TIM on it

*I know PTM7950 is real-life technomagic and all-that, I've used PTM elsewhere. Usually, older GPUs I never want to pull apart again.

 

[A Computer Guy]

Just a thought...If you running hotter and pulling more watts then your thermal paste might be settling in and working better. This could be a good opportunity to increase mounting pressure when the paste is hot and tweak power limits to run cooler assuming your thermal transfer has improved since your initial installation.

Does the Noctua NH-D15 include the AM5 offset mounting kit? If so then I would use it. It's proven on my non-X3D's to be useful on my modest NH-D9L and NH-C14S coolers.

Also it seems PBO + Curve optimizer is the way to go to really tune Ryzen CPU's. Since they hit thermal limits before others the trick is to manage heat production with power limits and curves to get the best performance aside from having a good cooler and well placed cooler contact across the chiplets.

I just use kryosheet with all my builds now - with processors hitting 80-90C these days i got tired of repasting every 6 months to maintain temps. I build mostly SFF - so it's even worse. Even TF9 and TFX need repasting.

Amazon.com

PTM 7950 is pretty weird tbh, I did my first 4090 repaste (110C hotspot :/) with it and 6 months later had to do it again and just put kryosheet on everything. It ended up way better, and lasts literally forever.

 

[A Computer Guy]

My cooling setup: Noctua NH-D15, 3 front intakes, 1 rear exhaust, 1 top exhaust(directly above CPU), Case is Fractal Define S, Arctic MX-6 paste sold and fulfilled by Amazon (fixed)

Ducting one of your front intakes to your CPU cooler might also improve the cooler performance so your not sucking in GPU pre-heated air.

What resolution do you run the game at? I'm running at 1440p and I just played with the framerate limited to 85 in the Nvidia control panel. The session resulted in 95.8C max on the 9800X3D and 51.3C average (although I forgot to reset max values before play I think) . The 4080S maxed out at 85.3C on the hotspot and 71.6C average.

Damn, I just did a repaste with PTM 7950 on my GPU recently. Sounds like Kryosheet might be in my future lol

Is there any reason to worry about Kryosheet destroying your system? I've seen people discussing the fact that it is conductive so any debris from the sheet could cause an electrical short.

 

[Jtuck9]

Can you not limit the max temperature in the PBO settings? I've been trying to faff around with fmax limits and temperature limits to try to keep voltages down across use cases. PBO enhancement seems a popular choice.

Yes you can specify a max temp with PBO. Power and clocks adjust accordingly.

If you are hitting high temps (which you are) during a CPU only load like cinebench then its not your case airflow that's the problem.

 

[Jtuck9]

I'm not sure how the boosting algorithm works?! I think it was during a Cinebench run that this 9900x instantaneously (literally) reached the thermal limit of 95c, according to Ryzen master, when I had PBO limits set to motherboard. This is using a D15 G2 (poor airflow granted). Memtest5 you won't hear a peep running at fmax, Y-Cruncher / Prime 95 you'll hear fans ramp up, OCCT varies depending on the benches.

This whole asrock burning issue springs to mind, as does the dual BIOS interface for a lot of these settings where the AMD pathway at least gives you a warning before tinkering.
