Aurora-R5, fans randomly super loud

I just bought a brand new Aurora for Black Friday.

Usually it runs fine and quiet.

But every once in a while, maybe 2 or 3 times a day, all the fans (cpu, front, and top fan) will suddenly and randomly run at 100% speed, making a super loud combined noise that sounds almost like a jet engine taking off. The noise will continue anywhere from 5 seconds to a couple minutes and then suddenly stop.

While the fans are running full blast, I'm monitoring the temperatures the whole time through command center and they are always low, something like 40C for the CPU, 50C for the ambient, and 55C for the GPU. Command center reports all fans running at a low rpm ~30% or so even while the fans are obviously running at 100%. 

It's really inconvenient because I work late at night and the sudden blast of noise wakes up anyone sleeping nearby or causes people to come running wondering what the commotion is.

I hit F12 when booting and ran diagnostics and everything reports fine.

How do I fix this extremely aggravating issue? 

Should I uninstall Command Center?

I see other posts describing a similar problem with Aurora fans randomly being super loud but I didn't find an official resolution.

Hi,

Update the BIOS to the latest here:

It's already updated with the latest bios (1.09)

Upon further inspection, the problem may lie with the Power Supply fan and the Top fan -- they seem to be the main culprits, revving up like crazy, super loud for no reason at all.

I do have the 460 watt power supply, which I see other people have reported having the same problem.

Any advised resolution for this random power supply revving?

One of my co-workers had the same problem with his new x51r3.  He called support and in the end they swapped out the mother board.

I'm having the exact same issue with a brand-new Alienware Aurora desktop.  I just took it out of the box and hooked it up, and that loud fan noise won't stop!

I agree that it appears to be coming from the fan at the top of the unit, the one that you can see through the vents on top.

I tried playing with the fan controls in the Alienware Command Center's Thermal Controls section, but even setting the "Top Fan" to 0% has it at 454rpm (and it's marked as being idle), so it's still making too much noise.  I wasn't able to find a way to turn it off completely, to confirm that it's the culprit.

This is a desktop that I mean to have in my bedroom, and no way will this cut it if the fan can't be turned down.
