C7H fans stop at high load

[IIINikolaiIII]

Hi! I'm having a problem with my C7H where all of my fans that are connected to the mobo stop spinning when the pc gets a higher load. This is causing a thermal shutdown. BIOS version 2501. Nothing in my pc has changed in a few months and now this started to happen. Thanks for any help.

Hi,
I believe I had just hit this problem where my CPU fan just stopped after a few hours of usage (not really super high load, but with 2 VM images running).

I am running on Linux and have a "while true" loop constantly monitoring the CPU temp every 5 seconds. When I came back from dinner just now, I just realized that the highest temp recorded was 128C, but it did not shutdown.

Does anyone know whether there's any settings in the BIOS/UEFI that I can use to force shutdown over a certain temperature?

Thanks.

P/S:
Specs:
3900X
C7HWIFI + 2703

95C is throttle point and 115C is OTP AFAIK.

ASUS WMI works by a 2 fold fix, apps access Super IO chip must use that and UEFI must have implementation that is not broken.

Someone did create a driver for use on Linux, link. From a vague recollection I recall someone saying it didn't actually access SIO correctly and still SIO could go nuts, leading to erratic behaviour. Dunno, though, this is what my vague recollection is.

I occasionally use Linux mint, bit of a noob to linux, so I can't really answer much on it. As I know how my system behaves based on data collected for a profile on WinOS I really do no monitoring in LM.

You can adjust throttle point, Precision Boost menu on Extreme Tweaker and or same menu in AMD CBS/AMD Overclocking has the settings. Allows reduction, but not increase.

Hi @gupsterg, thank you for always being so helpful!

So, I guess the fan fix of "002" will be introduced in the next official ASUS release?

NP, I would assume so.

I have been using 0002 with some of my own mods and so far been fine. At times system been in use ~12hrs in one go, but I was in WinOS and used apps which use ASUS WMI when looking at monitoring data.

Watch the WMV in this ZIP, seems to me after UEFI 2606 a bug has crept in, I have sent to Shamino, hopefully ASUS fix soon...
