GPU temperatures on idle higher after changing Motherboard

[khesax]

Hello, so I changed my CPU and Mobo from a i7 3770 and a ASUS P8P67-M to a i5 11400F and a MSI B560M Pro-VDH and I noticed that my GPU got hotter on touch, checking the temps on HWInfo revealed that on idle the GPU was sitting at 40-50 with the new mobo while with the previous one the idle temps were 30-35, looking for other temps I also noticed that the PCH temps were higher than the others and reading through other forums someone said that since the PCH diode is near the GPU, it could be transfering some heat to it through the PCI Slot, is this normal?

Edit: My GPU is a Gigabyte RTX 3070 Gaming OC, Rev1.0.

Edit2: I also touched the back of the motherboard and it's pretty warm, CPU is running 40 on idle.

It would help to know which graphics card you have. Also the new platform may have different fan profiles so your fans run slower (and quieter).

Right now I dont have any side panels on my CPU because I'm still testing things so I dont know if it could be affecting on something.

Using your fingers to measure temperatures is generally not particularly useful and temperatures are normally a lot lower than people think they would be.

Not having the side panel on definitely changes things, how it changes is harder to determine. It could make it better, could make it worse. But it does change airflow.

40-50c idle on a 3070 seems pretty normal to me, my 3070 idles around 40c +- a bit depending on ambient temperature and CPU load.

MSI GeForce RTX 3070 Gaming X Trio Review

The MSI GeForce RTX 3070 Gaming X comes with the largest out of the box overclock today. Thanks to its large cooler, the card is nearly inaudible at full load, and the fans turn off completely in idle. In our review, we also saw excellent overclocking on the GDDR6 memory chips.

Most 3070's seem to idle around 40c so I would rather say that your previous numbers are the odd ones if anything. Are you sure the GPU entered passive-fan mode properly? If mine does not, which for some reasons happen at times where the fan is left on ~30%, it idles around 35c instead of 40c.
