Aurora R9, Fans stalling?

I thought I mentioned this before but maybe not on your thread. This is a known issue. But looks like you have it worse than I do. My ML120 Pros stall when set to spin above 70% at temps past 60C. So the only way I can save my R8 from burning up is to set a fan curve that maxes out at 70C.

So 70c is the max, what do you set at the offset? I realize my max and offset may be different.

So I set the offset to 100%. This should mean the fans are spinning at max, all the time.

AWCC shows 56% top speed and front at 33%.

I'm not sure that's accurate or not.

I called AW tech support who ran me through the diagnostics. Both front and top fans produced an error during the diags.

I'm at bios 1.0.5

If there's no fix, I'll replace the fans.

Interesting, I have my son plating Fortnite and even with awcc set at 100% offset, the top fan is frequently cycling up and down. 

shouldn't it stay throttled up? 

I checked awcc, it was showing 10% fan speed @70c. 

looks like I have the same issue. 

Would you mind uploading a picture of your Fan curves?

updated awcc today, noticed fans now stalling. System was staying cool for quite some time and then the fan's seemed to spin down to 10% in awcc. That drove temps very high.

You need to disable the AWCC inactivity timer otherwise the fan profiles goes back to factory default. Or you can keep manually opening up AWCC. 

How do I do that? I don't see that option in the awcc settings.

Here's my cpu fan curve set to avoid the 70c fan stall. I'm not 100% sure I have this right, but close to these settings prevented my fans from stalling while my son played fortnite for the last hour.

I think I wrote the last part of my last post wrongly.

In order not to stall my ML 120 Pro, I set it to go no faster than 70% on a curve. That's the magic speed I got where for all temps up to 99C, the fan won't stall.

If I set it to 100% preset, like you said AWCC won't show it as 100% but if you open Intel XTU, you can see the fan hitting the max 2400RPM. However, that is only when the CPU idles at ~30C. Once it heats up past ~65C, fixed offset doesn't work, it starts spooling, like a ramp up and down and eventually stalls altogether. Again, setting fixed offset to not be more than 70% works for me.

If I plug in a 92mm Noctua PWM fan in FRONT_FAN header, the magic speed goes up to 75%. Beyond that, stall too. Almost cooked my GPU VRMs before.

@digitalwiz :

Fan curve. Middle dot is 50%/50C.

What fan model is your top fan? Mine will only report up to 56% at 100% offset. Under real world scenario, with 70c curve in place like yours, it doesnt register more than 41% at 65c. 

@digitalwiz :

My top fan is ML120 Pro. 56% at 100% offset sounds about right. And yes, with my curve, I go up to around 40% when CPU at 65C.

Use something like Intel XTU to see the true RPM reading on your fan. It should show the correct speed based on the % you set.

Interesting, looking at your R8 AWCC screen shots.  The R7 (which as some may already know, uses the same z370 motherboard, sans a bios update for 9th gen) comes with the older version of AWCC.  The older version of AWCC shows fan speed by RPM, and also shows the percentage in parenthesis.  It allows all third party fans that I have tried to be set manually to 100%, and to run and display running at that speed in AWCC. 

Will the R8 awcc work on an R9?

Followup: It shows the same available version on the R9 as it does the R8.

@r72019 What version is your AWCC on your R8? If I can downgrade and get better fan control, it's worth a shot.

Thanks,

@GTS81 When I set the offset to 100%, rpms are: System: 2559, Chassis: 1460.

When I set the 70% offset limit, rpms are: System: 1871 and Chassis: 1118.

It kinda that to have a normal sounding system, you have to throttle your fans well below their capability when the system is loaded up, or they will stall out.

This is a dell engineering issue. They could fix this if they wanted to.

@r72019 :

I guess it's a fair world. You get the RPM readout. We get the 9th gen CPUs.

I'd only consider it a fair trade if I could shove whatever fans I want here in Frankenstein's bride without generating a startup error.
