Hi!

So I just bought a new PC. Here's the details:

CPU: Intel i9-12900KF
COOLING: ASUS Ryujin II AIO
OS: Windows 11 Home 64 bit
MOBO: ASUS Maximus Z690 Formula
GPU: RTX 3080 Ti
PSU: ASUS Thor 1200 W
RAM: G.SKILL Trident 2x16GB DDR5 6400
SDD: 3x Samsung 980 Pro 2TB
CASE: CORSAIR iCUE 7000X

The Chipset idles between 63 and 69C! Comparatively, the GPU has a 45C idle with a 55C load in MSFS with every slider to the right. The CPU has a 35C idle and 50C load at the same settings and the SSD's are sitting at 45C during heavy writing. Any thoughts? I've heard ASUS doesn't provide thermal paste / pads for the chipsets sometimes and I haven't poped open my MOBO to look. As for other cooling the case comes with 3 pushers in the front, 1 in the back pulling, my AIO has 3 fans at the top pulling and I have 3 aftermarket corsair fans on the side pushing in - but I left this steel plate on so the air is directed at the back of the mobo... (I did this because I don't know how to remove the metal plate and I think I'd need to take the entire PC apart to do it.)

Thanks for any advice.

Do you OC? 

I'm at 5.1 and at idle is at 35C. This 12900K will easily overheat if is a bad OC. 

Before checking thermal paste take a look at the fan speeds, please.

As I read it, his issue is with the motherboard chipset, not the CPU.

If there's no active cooling on the chipset, those temps don't surprise me.  It's not really a meaningful comparison to consider the chipset temps against components that have dedicated active cooling. 

That said, I'd want to make sure there's some direct airflow on that part of the motherboard.

Ahhh, I didn't pay attention. I think that checking the case fan speeds and connections is worth a try before anything else. Actually on my PC instead of using the MOBO plugs for the case fans they hooked them up together with the CPU fan, it was easier for them related to the wiring, that translated to high temperatures. I found that by mistake.

I think I'm gonna let the AOG Armoury-Crate do the Overclocking through the AI setting, if I choose to. I'm pretty content letting the i9 do its thing stock, actually. I can run MSFS at 60FPS at Ultra, so I don't really see myself pushing the envelope.

Thanks. I only threw in the other temps to show there is good airflow in the case, I guess just not over the chipset. The 3 front fans are unobstructed, and it should be hitting the entire mobo from the side. I also have 3 side fans that have a metal plate directing air across the bottom of the mobo and then out the back.

Hadn't thought of wiring. I actually had no idea what I was doing and couldn't even find where to hook the AIO wires to the AIO_Pump and CPU_Fan so those slots are empty right now. Maybe I'll watch a tutorial and see if I can figure it out.

You should have the MOBO book documentation, if not you can download it from the manufacturer. You will find a number of plugs available for the fans. As I mentioned (in my case) they didn't use them almost at all. The problem with that is that the MOBO will assign different fan speeds (auto, low, high, or defined speeds) via AI future based on temperatures. That was my initial issue with the temps. After I put everything where it belongs and adjustments I was able to control properly my temps.

Yes you could (if you wish) AOG Armoury-Crate do the Overclocking through the AI but, it will not be as much as effective in maintaining proper temps, especially if is not reading proper fan hookups.

Based on what I went through I sought that would be somehow beneficial to check that first before getting involved in more complicated tasks.

I hope it will help. 

How accurate is the chipset temperature sensor? I know on some motherboards they are not exactly to be trusted. Any idea what the maximum safe temperature is on those chips?

However your temperatures definitely seem hot; for comparison I've just built a 12th gen Intel system and my B660M chipset idles at 34'c, there's a small heatsink on the PCH but I've only got two intake fans and one exhaust in an mATX case, so it's a compact space that heats quite quickly. However, I have spent a few hours fine tuning each fan's minimum RPM and what sensors drive their speed increments. I've also undervolted the CPU by 0.15v which has shaved 8'c off my processor and VRM temperatures.

ASUS MB variable boost chipset max 26% custom case fans.

I dunno how accurate it really is. I googled around, and a lot of users are reporting 10-20*C hotter temps. An ASUS specialist on their boards commented that these temps are normal and that the chipsets max temp is 108*C.

That said, I'm still not comfortable playing hours and hours at 65-75*C, so I'll probably end up just paying money to take it into a nearby MicroCenter and getting an "expert" opinion. I'm within my window to return the board to Newegg for another 20 or so days.

Maximus Z690 Formula is a very high end board. You would think this wouldn't be an issue but if you google it you will see many owners are having this issue. Some seeing chipset at 90C under load. 

I note that some MSI boards are seeing high PCH temp too. 95 degrees used to be regarded as max under load, but I'm not sure whether temp thresholds have been increased with Z690 or not. I read somewhere that max temp before issues is 110.

I have a Z690 Apex. I'll check the temp and report back. 

 

Edit: My chipset is 59C at idle. Seems most people are seeing temp higher than they are used to for the chipset with Z690 Boards. My advice is don't worry. I'm not. Max permitted temp may well be higher than we are used to in the past. If you are concerned then drop Asus an email and inquire. 

What's the temp under load? 

Now consider my issue with the EVGA RTX 3090 FTW3 DDR6X Junction Temp. 95 degrees under load and some 3090 owners are seeing 110 degrees and throttling. 😀 The latest parts seems to be pushing temps higher than we are used to.

That's a low temp under load.

Thanks for the feedback Martin! I'm gonna take your advice and rock with it. It's hard getting used to seeing 75C on a chipset but I guess I have no choice. Thanks.

Mine is 59 at idle, so I would expect it to be getting close to 80's under load. 

You said 63 to 69 at idle before. Now you say 75. So is that 75 at idle or load?

Give me the load temp?

63 to 69 idle, 70-75 load. I was just giving the max temp I've seen after hours of high intensity gaming.

That's a perfect temperature at load. You have zero issues. Enjoy your PC. 😉
