PCH idle and load temps

Hi guys,

So I have a MSI Z390 Gaming Plus that I used with a MSI RTX 2070 Super Twin Frozr 7. However, I just got a MSI RTX 3090 ti Suprim X and that card is a giant and runs much warmer.
Once installed, it covers pretty much the entire heatsink of the boards PCH chipset.
After hours of gaming I noticed the PCH went up to 73°C on hwinfo64 max temperature and lowest at idle stays around 49-51 °C.
Are those temps acceptable, normal? or should I worry?
I dont remember seeing the PCH temp that high while running the 2070 super before, which makes me believe that since the 3090 ti gets up to 65-70°C on load, it dissipates the hot air right to the heatsink of the PCH since it is covering it entirely basically. Maybe I am wrong.
Please let me know what you think about these temps.

Thank you very much

the temps look pretty normal for z390 boards.
the GPU covering the chipset, passive chipset heatsink, and chassis dissipation can all affect the chipset temperature. you could work on these parts to improve the chipset temperature if you're worried.

It's not a critical temperature. Most graphics card coolers will blow air towards the board and the side of the case (as opposed to front- and rearwards), which will of course heat up the components on the board. But no matter where the air is blown to, a 3090 Ti can easily draw >450W during gaming and poses a serious problem for many systems, in regards to elevated internal and board temperatures. As well as the PSU having to be quite a good and powerful model as well (goes without saying).

If you want to improve this situation, see if you can improve the case airflow somehow. There's no urgent need to act, because it doesn't reach anywhere near 85-90°C or so, but that's how you can lower it, by exhausting the heat from the case faster. Or, as with the upcoming "early adopters money grab" 4000-series cards with a similarly outragous power draw, some people will find that they actually need a new case, like a Fractal Design Torrent, which can deal with such TDP without a problem.

Thank you citay. Appreciate your reply
