Fans forced to 100% when CPU reaches 75C

[mdzcpa]

I'm a bit confused about the problem here.

Am I the only one that has no problem simply checking the Critical Temperature box and setting curve however I want it?

A pic of CPU Fan control is below. I changed the name to RYUJIN Pump as that is what I run off the CPU header. But in any case I can control this header and my case fan headers any way I want by clicking critical temperature box and changing the curve. I've set full fans to not engage until 95 in this example.

It's just about the UEFI fan control "application", not some Asus Windows software. Possible that it can be set there, but many don't bother with installing this kind of software, at least I don't.
Edit: And why not make it available in UEFI also, if the Windows software can do it? Seems like some arbitary, absolutely unnecessary limitation without any reasoning.

So you don't want to be "bothered" by the solution. Understood. Carry on.

Sorry? With solution you mean Asus Windows software?
That's just a workaround really and as said, why not also make it available directly in UEFI? I don't understand what the problem is...

I have a similar issue to the OP. For whatever reason, my chassis fan 2 header starts spiraling out of control towards max speed as soon as its top temp threshold is reached. This, regardless of what I have the max speed set to in the BIOS. For example, right now I have it set to max out at 60% at 70C. It does that, but as soon as its temperature source starts to go past 70C by even 1 or 2 degrees the RPM shoots up to 100% in a few seconds and stays there until it drops below 70C. Same behavior when I have it set to 75C or whatever, and it's just that header doing it for some reason. It's not the fan or cable or anything because I've plugged other PWM fans into the same header and the behavior is unchanged.

I have a Maximus XI Hero Wifi running the most recent BIOS, and it didn't always do this. The fans ran fine for months, possibly until I applied one of the more recent BIOS revisions earlier this year. I can't pinpoint the exact time unfortunately.

Anyways, I'm now resorting to buying a Commander Pro and running all my chassis fans through that instead so I actually have control over them via Link or icue (which seems to run reliably with my AIO fans). This also eliminates the limitation of the low temp caps and only 3 speed points in the Q-Fan control in the BIOS. Rewiring it all will be a giant PITA though.

Bumping this thread to say it's ridiculous how this restriction is still in place, especially for Ryzen 3000 users. My 3900x easily spikes close to or above 75C while handling background processes or opening new browser tabs, which means every time I open a new tab I have to hear my cooler go from 50% to 100% for 5 seconds before spinning back down (ramp-up settings don't seem to do anything). Ryzen Master reports a temperature limit of 95C so 75C should be perfectly fine for these processors.

Also "use Ai Suite III" or other fan control software is not a real solution since multiple users like me dual boot between Windows and Linux and would like noise/thermal performance to be consistent regardless of OS and without having to tinker with multiple fan control programs.

same here i have a 360 mm aio 6 x 120mm push pull , 3 x 120 mm on top of case , 2 x 120mm bottom of case , 1 x 140 mm rear

when i hit 75 c it sounds like a jet liner . and i can watch my cat get blown away .

i have my 9900 ks @ 5 ghz / 4.7 cache @ 1.23 v and i try to keep temps below 65 c

I have a Crosshair VII Hero WIFI paired with a 3800X. This issue bothers me a lot.
Ryzen 3000 is known for the hotness. Die temperature goes around 60 or 70 very easily.
For now, I set motherboard as the temerpautre source for all my chasis fans. Since motherboard temperature is almost a constant, these fans will pretty much stay a constant RPM, which is good enough for providing some airflow. Right now only the CPU fan will ramp up, but it's acceptable.

ASUS really need to fix this issue. This limit is totally unnecessary for something labeled 'R O G'.

If your a Linux user you can't use the solution.

Another issue with this solution is a lot of the AM4 motherboards use ITE IT8655E Super IO chip, this embedded controller can exhibit erratic behaviour when a SW accessing it doesn't support "ASUS WMI", at times ASUS's own SW has not been correctly done to use with the stated EC.

i guess this works kinda ish as a work around . i delided my 9900 ks and relided it with rockit cool ihs . i now am 5 ghz / 4.7 cache on 16 threads with ram @ 4200 mhz and my cpu on one core hits a max temp of 65 - 68 c on one core in battlefield 5 with 100 % cpu usage . other games im 60 c and under .
