I got this motherboard about 6 weeks ago, but noticed it was making a lot of squealing noises. It got worse, but then I discovered that it wasn't actually making any squealing noises itself, but they were coming from my PSU (the Antec Earthwatts 500W I got with my Sonata III case), especially during disk access (on both my usual SSD and a Velociraptor).
I made sure it was the PSU by rolling up a sheet of paper into a tube, putting it in my ear and then then listening close up to the mobo, PSU and other parts. Great trick for isolating the source of such noises!
I replaced the PSU with a Corsair TX650 (needed a bit more oomph for the graphics card I recently got), but it was still squealing away horrendously, even during idle.
Then searching the internets I read about how somebody disabling C1E Enhanced Halt State in BIOS stopped the squealing they were experiencing, so I tried it and it worked for me.
But why should C1E cause this squaling in my PSU?
And are my electricity bills going to go through the roof because I now have it disabled?
