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

[PeterK77]

You installed a noctua fan over the pch heatsink (cover)? Isnt there the ROG RGB logo there?
How did you manage to install the fan? *What’s holding the fan?

Currently in Windows 10 the PCH temp stays around 68 degrees c to 71degrees C in most cases.
Still pretty high. * My ambient temp is 24 degrees C.

Apology for late response, but I am not visiting this page too often. It is easy to install fun over heatsink, when you disassemble original heatsink cover. Next you need to measure original cover and according to dimensions new modified model needs to be made. Of course, new model already contains intended fun attachment shape. Hardest part was to measure all dimensions with "home" tools such as caliper. The rest is to print new holder on some 3D printer (I used Prusa). As you can see in picture I used original screws to attach this holder to PCB. Fun itself is under angle to get higher volume of air to cool. I know it looks horrible everything, but what I need most, is this board to be reliable. Everything else is second. Probably noctua fun can be bought in black color, so it would look better. My case doesn't have any transparent covers, so I basically don't care about appearance .

Hey sdmf74

Thanks for trying to be helpful, but I'm acutely familiar with the architecture of Z590 chipset - it wasn't ASUS' choice; ASUS don't design chipsets. It was Intel's decision to switch the DMI link speed from PCI-E 3.0 x4 to PCI-E 3.0 x8. As ASUS was engineering the motherboard, this should've been taken into account and PCH heatsink design beefed up to ensure the PCH is being cooled properly.

I have read the thread through and through, ahead of writing up my 1st post, and as I'm sure you can agree, solutions posted here so far are half measures and not permanent fixes.

The only two permanent solutions to this problem that I can envisage are:
1) ASUS release new BIOS version, with PCH undervolted (unlikely as might cause instability; unless the PCH is overvolted in the current BIOS version)
2) ASUS release a revised PCH heatsink and agree to supply at no additional cost, to all who purchased the board, and pull the existing inventory from the channel to apply the revised heatsink (extremely unlikely, as this would mean lost revenue and reputational damage - this would basically be ASUS admitting that this is a PCH heatsink design flaw)

I'm unwilling to be applying half measures to limit the connectivity options which I paid for (and it isn't a cheap mobo we're talking about here), increasing fan speeds, buying new fans or cases - just to accommodate the product that should not have had this design flaw in the first place. It is your right of course to disagree with me and do all those things, if you prefer.

I sincerely hope ASUS will own up to the problem and fix it, but given the choice between entrusting to a soul-less company and returning what I consider to be a flawed product, I choose the latter.

And finally - I have returned my flawed Maximus XIII Hero motherboard, exercising my right of return, as any sane consumer would, and I would highly encourage everyone who can, to do the same. I purchased an ASUS MAXIMUS XIII Apex instead (best motherboard I could find with an actual PCH heatsink), and here are my temps (note that I didn't buy a new case or fans - neither of which I need; I didn't increase the fan speeds, nor did I apply any other shenanigans):

So you exchanged your motherboard for an Apex w/ one Nic and now you have a PCH temp of 66c

I temporarily disabled one of my nics and have 59c

I noticed at least two people asking what disabling APSM does.
Read the thread I already explained it.

I can enable apsm and open hwinfo64 and watch the whea errors rise from zero and keep going up and up!

i have hero maximus xiii and had also high pch temp, i read about it and it turns out its the thunderbolt thing. try turning off thunderbolt in the bios, if you dont need it, and see if your temps drops
