Just stick a non-PWM (3 PIN) fan there, it will run 100% all the time. 

Is it possible to switch the leads and run the front fan from the CPU fan lead and run the CPU fan from another lead so it spins at 100% even all the time would be better than the system cutting out under load. 

The problem isn’t with the noise. The problem is with the fans not spinning fast enough on one side and then spinning down to 10% on the other side because the fan controller gets all sputtered out.

Noctua also includes low noise adapters with their non-industrial fan lineup if it's too loud at 100%. 

Lol, I have not yet begun to rant. Seriously though, the bottom line here is two issues.

1. Stock fans are too noisy, but cool effectively. 

2. Ml120pro won't spin fast enough to cool effectively under load, due to 70% issue, but is quiet imo.

So it's really a choice to return to stock for cooling or choose aftermarket fans for less noise.

I don't see any other options. If the aftermarket fans could spin at their limits, I think they would be fine under load.

I'm really shocked a cartoon game like fortnite loads up the cpu the way it does. Fallout 76 runs in the 48-60 under load in my current config, at 1440p. Fortnite runs in the high 70's and low 80's and I see rare spikes to low 90's.

The 2080ti runs 83c in fortnite and 63 in Fallout 76.

So the game is also an issue.

This has been good for all to see the options and effects of these changes and choices. In a perfect world, it would just work, like it does on my Falcon mach 5. It's just not falcon quality. That's the bottom line, imo.

What Alienware model ?

What main-processor and video-card is installed ?

What size power-supply?

Did you get liquid-cooling or not?

My (loaded) Aurora-R6 is quiet (even during WoW or Fallout-4 gaming at 1440p and High/Ultra settings). Only thing that makes it the slight-bit noisy is OCCT Power-Supply stress-test (but can still barely hear the fans).

It's in the photo above. I'm wondering if you have different model fans, since it's the fans making the noise. 

Why does the R9 look as though there's a vinyl coating over it? Is that stock from Dell?

Special edition lunar RED to go with the limited edition CPU.

Possibly, as mine was built in 2017.

Those high-end CPU and video-card will heat that little-box up pretty good.

So, you are sure it is not just the Nvidia card getting a bit noisy when stressed?

And if not, which fan is noisy (the front-fan or the radiator fan)? Which one?

My fan are stock, but others have been swapping them on recent Auroras it seems. All I know is a replacement fan must be a match in all specs ...
- Size and pin config
- Voltage
- RPM
