Sonata ticking/clicking

It was good while it lasted. I bought the case sometime last fall and went from 50db down to around 25db or so. The silence was eerie for a while. I'd seen a few posts in various forums mention a ticking noise the Sonata sometimes makes. I could hear it on mine but it was so faint I had to stop typing to hear it and it wouldn't last long enough for me to get down on the floor to see where it's coming from.

No more. Today, the ticking suddenly became much louder and lasted long enough for me to decide it was coming from the PSU, possibly the PSU fan. The tick seems to be somewhere around 10-15 Hz.

Is it possible that Antec is doing some sort of PWM for the PSU fan and that's what I'm hearing?

 
Email Antec, they'll probably replace it for you. Or just open up the PSU and replace the fan yourself.
 
You cannot hear 10 to 15 Hz. Are you a whale?

I believe the PS just drops voltage to slow down fans, not PWM. I say this because I measured only 5VDC on the FAN ONLY plug at startup, with a badass DMM set to fast.

The stock fans in Sonatas are known to be cheesy. My own had a bad case of the clicks. Unplug it to see if the clicking stops.
 
You cannot hear 10 to 15 Hz.

Erm. Drum your fingers on your desk 10 times per second. Do you need to be a whale to hear that?

 
My Sonata came out of the box with a gawd awful tick. I took it back to the store immediately. They didn't have another Sonata or 380W Antec PSU, so I convinced Fry's Electronics to give me a 450W Antec PSU (Utterly quiet).

LoL, that has nothing to do with it. The frequency is the actual wavelength of the produced sound itself, not how fast it is being produced.

Nothing to do?

Then I guess f = 1/T is wrong then.
