Asus Z690 Formula Chipset / PCH extremely hot at idle

Hi all,

I have raised a ticket to try and get some advice as I dont know if this motherboard needs to be sent for an RMA replacement but so far I have not had a response.

But I am having a issues with the chipset temperature on this motherboard as at idle it is settling at around 88-89 sometimes 90C! Surely this is way too hot??

Im also trying to run a Teamgroup DDR5 6400mhz kit at xmp rating and Im experiencing boot loops, and am unable to apply much of an overclock to a 12900KF chip without constant bootloops.

Things feel unstable and to get into windows 11 at XMP speeds (6400Mhz required much more than the rated 1.35volts on the DDR5 ram)

Can anyone confirm the Asus z690 Formula idle chipset / PCH temperatures for me?

Is this board defective?

The attached screenshot is from a bios reset (everything stock apart from activating xmp on the DDR5 and managing to get into windows) Temperature of the chipset is from several seconds after loading windows

Any assistance would be greatly appreciated.

Possibly Asus forgot to apply thermal paste to the pch, they did the same thing on the x570 formula

I have an Asus board but my temps are nowhere near those two. But I have the cheapo one as I am peasant I think mine was like 58C. Not sure how accurate the temp reading from HWinfo is though.

Something is definitely fishy with the Asus formula boards, that's multiple chipset models in a row with high pch temps, dunno what Asus is doing to these formula boards but for something reason they have issues

My Strix Gaming A reaches 65c just booting Windows up, Just checked and it's freezing here in the UK it's peaking at 73c in games god knows what it's going to be like in summer, This is extremely poor from Asus, They have either used cheap thermal pads on the chipset or not used any at all by the look of it, Chipset hotter than a 16 core CPU is just baffling 100%

I'm on a ASUS MAXIMUS Z690 FORMULA and im getting about 66 - 68 degrees during gaming. Out of curiousity, at what temps should we be worried for the PCH?

I think not. It feels hot like that :(

If you've not had it long I'd try exchanging with your retailer. If the replacement does it I'd try a different board.

It seems to be a common issue, and it's very disappointing on one of their high end boards.

Asus have had a few issues recently with their high end parts, their strix graphics cards had issues with rattling fans for example.

Z690 Strix-A D4 here.
Usually there are 4 screws holding the passive pch cooler in place. You know on cheap boards and such.

After the Strix-A got finished clearly the marketing department got hold of it and made some very bad design descisions that left my pch with only 2 screws and a heat trapping plastic cover on over 60% of the passive cooler.

So i removed all the needless plastic that clearly has been put there as an afterthought since without it all the clearence issues with big noctua coolers are gone in an instant.
I believe they even cut the aluminium coolers weight to make place for a stupid white ... cable binder?

Then I switched the 2 mm cheapo pad that already sweated out most of its silicone anyways with 1mm 14 kw/h pad and a glug of thermal paste.
The cooler itself has two silver mounting spacer/holes. Those i tightened against the cooler itself. I got a 160 degree
trun on both out of it. Makes the cooler stay closer to the pch.
And i screwed very very tight the 2 measly screws that hold my pch cooler in place.

My record temps from my pch have been 91c with all m.2 slots populated after copying only 220 gig with one transfer.

Now i can try whatever i want i never see 70c. No matter the bios ASPM options or how many copy tasks i run in paralell.

In your case just get to the backside of the board and screw tight the screws they left on your pch.

Sounds like it can be improved on Asus boards, but I should imagine this will void your warranty :o
