[Z590] Asus ROG Maximus XIII Hero - PCH High Temperature

[EncodeGR]

That's all nice but what's the use of buying a board for those specific options if you shut them off ?

I use the wiFi, the Bluetooth, the board only has USB audio . I only have 1 Ethernet port. Well, I can disable some Sata ports

I bought the board mainly for it's overclocking capabilities, VRMs, Voltage Control etc, as well as its cooling solutions.
But definitelly agree with you. Well, perhaps this board has higher pch temperature exactly because it can handle all that stuff exceptionally well.

We'll see. Maybe future firmware / bios updates will improve things.

Those photos are not mine. I have removed all thin films from the heatsinks (white) as well as their base (blue).

What the first photo shows, is the M.2 metal heatsink, merged with the plastic PCH cover.
The second photo just shows the pch metal heatsink.

That plastic cover goes on top of the PCH heatsink, essentialy blocking all airflow. No idea why they designed it like that.

I just got my board set up, just installed Bios 605. My chipset is running at 65° C in the Bios Monitor.. Did you ever get it resolved?

Another XIII Hero owner here with PCH 74-80C. Running BIOS 605...

Disable thunderbolt in bios and temps should lower.

Same here, 61 degrees in idle.

This z590 chipset is probably a bit hotter, Pcie 4.0 requires more power after all.

Z590 chipset lanes run at PCIe 3.0, only CPU lanes are PCIe 4.0.
PCIe 4.0 chipset lanes would probably require a fan.

Its true... in that case I do not know the reason for the high temperatures. Bad design probably?.

PCH 59/60C degrees idling in my case.

Dear all,
After checking internally, the temperature of your PCH is normal.PCH can stand the heat up to 108C.
Eventhough the device is idling, the system is still running, so an amount of heat would still be generated and you still see certain temperature of your PCH.
Please don't worry. Thank you very much for your feedback.

Ok, good to hear that!! Thanks a lot for the answer!

Came across your post as my Maximus XIII Hero PCH temp is also 75-85 on idling, even inside of one of the best cases known for high air flow: Cooler Master h500m. I have a strix 3090 gpu and i9-11900k, i was wondering, if i mount the gpu vertically, would that help ? I think now the PCH gets hotter because of hot gpu and also gpu gets hotter because hot PCH, both gpu and pch next to each other not really good combination.

Anyone tried that ?
