CPU temps too high ?
CPU temps too high ?
My I7 9800X3D is always running at 52 degrees c at idle. I removed the AIO and put in new paste, but nothing changed. Fans are blowing in the right direction. Every time I open a browser, the AIO fans spin up and it becomes loud and annoying. I've adjusted the settings, but I don't want to stop cooling the CPU. I haven't had any instability or BSOD issues. Everyone says they should be around 40 degrees c, but I'm worried it might burn out if this continues.
And why is that an issue?
Online discussions about PC specifications often feel like recycled information, lacking real experience or personal insight. Many factors come into play—such as AIO capacity, ambient temperature, whether a negative CO is active, and other unpredictable elements—that don’t consistently lead to clear conclusions. What truly matters is what performance you achieve when the system is under heavy use.
ya, I figured I would have people ask me this. lol. Like I said in my post, I know I shouldn't be making an issue of it since I have had no instability problems, "however, I have heard of CPUs having their life shortened due to high temps and since most of what I have read indicates that 52c is rather high fir idle, I got a little worried.
As for your question. Under load..... When gaming, I am hitting around 95c but still no instabiliy.
I just wanted to ask around to make sure I wasn't harming my CPU by continuing to let it run like this.
Thanks for the reply.
It's experiencing instability with the new CPU. Consistently pushing temperatures close to maximum leads to overheating and reduced performance over time. Running at 95°C is particularly problematic, as it triggers throttling that lowers efficiency and lifespan if the CPU isn't upgraded regularly. Frequent upgrades won't significantly help if the failing component remains. Could you share the specific AIO model?
What's your ambient temperature, considering the local climate?
The maximum should be around 95°C at most.
As before, what AIO are you using?
I’d avoid going below a 360mm AIO on the 9800x3d—better not go lower than 280mm.
An Arctic freezer iii ranging from 280mm to 420mm seems like a solid choice, offering larger radiators and good performance for the price.
I currently use an Arctic freezer iii 420mm AIO on my 7800x3d, which still maintains around 75°C allcore R23. At the moment it’s idling at 50°C, but it feels like a mild day today, so I’d estimate about 26-30°C inside.
Under Allcore R23, it’s maxed out at 82.5°C recently.
Zen 4 and Zen 5 tend to push up to the maximum by default.
Your climate definitely influences your overall temperatures!
Your CPU is operating cooler than the AC, which is a bit excessive mainly due to cost and limited situations, but more won't hurt.
My 7800X3D runs and performs warmer than my 9800X3D even when not under load. I believe this is related to the cache structure, which explains the lower maximum temperature.
That said, most of us, including my 9800X3D, remain stable at a -30 VO Curve (negative). My 7800X3D has been noted as reaching -30 too, but it might be due to silicone or a previous component combination. For you, it would be wise to try a -15 VO Curve and adjust from there.
For the general case, let me know what cooler you're using; if it's below 360, that's likely the problem. You could begin with a -20 VOC and monitor the temperatures—performance loss should be minimal.
Yeah I know I like to overkill my cpu coolers 🤣🤣
BUT this time there’ is a reason for it I’m looking at upgrading to the 9950x3d to sit on it for a few gens ..
Yes the 7800x3d cache was placed differently so hotter..
I think there is definitely diminishing returns on a 420mm but my new case
( there is pics in members system thread )
Fitted a arctic freezer iii 420mm in it ( most cases don’t ) So why not🤣
I stand by my statement of 360mm should really be the lowest size for a few reasons most of all the degradation if it’s consistently hitting 95c..
I own an NZXT 360 Elite RGB in Alabama where humidity stays high all year. My home temperature is kept around 72°F. Recently, I swapped out my motherboards from a Gigabyte x870 Auros Ice to a B850, which improved performance. When temperatures rose, I noticed better stability compared to the previous setup.
Was about to ask why you changed from an X870e to a B850. This is why one should read through carefully before commenting. Just ensure both are x16 and don’t lower with an m2, I’ve only personally seen it for Gen5 but only with one x16 slot.
Anyway, if replacing the motherboard you noticed this—it’s one of these three that come to mind:
1) Poor paste application / improper paste use
2) Cooler not installed correctly/uneven pressure
2a) Misaligned socket, Thermalright contact frame
3) Incorrect or faulty BIOS settings
4) You didn’t specify the board, if it’s an ASRock, remove it immediately.
No, it's an Asus ROG Strix board. It's tough to locate boards with 2 X16 PCIe slots, particularly white ones. My PC is entirely white, which limits my options. I've reworked my CPU and replaced the cooler block, but that didn't resolve the problem. This situation began after switching from a Gigabyte X870 to an Asus B850. I'm considering ordering an ASRock X870 white board with a second PCIe X16 slot to compare results. If I encounter similar issues, it would confirm my mistake. Otherwise, I hope the ASRock model performs better than expected. If not, I might have to replace my all-white PC with a black one.
