Just an update...

This only happened twice and it was during the first two days of use. Since then it's been humming along quietly and my wife is not scared anymore  Grin

It was LOUD though, for anyone that might encounter this in the future, just unplug and re-plug, hopefully won't happen again- so far so good 4+ days straight!

Okay, mine's been working 18 hours in "silent" mode now... Pretty sure when it got loud yesterday it was a glitch.

Seems the PSU is not smart enough to ramp the internal (very loud) fans down after they kick in, unplugging and rep lugging (once cool) solves it. If I can find a way to remotely control it or maybe a timer that would be cool, pretty sure Belkin might make something...

I just woke up and the PSU on my backplane was SCREAMING!

It runs normally kinda noisy buy nothing crazy, certainly tolerable. It must have been running around 8 hours total and I woke up to it sounding like a very loud hair dryer. It was cool to the touch and everything was working. I unplugged and re-plugged and it's back to "normal" right now.

Is this PSU on a timer to kick into high gear or is it dynamic based on the temp? Will pointing a few fans at the PSU prevent it from entering the crazy-loud mode?
