RT-N66U making noise

[doctor ladd]

I first noticed this today. In a silent room it makes a faint scratching sound.
It seems new to me but I have always kept it on a noisy laptop cooling pad until this week.

Has anyone else noticed this?

Yes i opened the case of the n66u to install the sd card but because its such a hassle to open it i just left it open to test out the sd card.
But with the case open sometimes i hear a very highsqeezing sound like it hums at a very high tone or something i dont think you have to worry about it

sounds like "coil whine" to me....

I've seen that term pop up a few times but haven't found a good resource to learn about it.

I called Asus tech support but waited on the phone for way too long, I think ill call back today. I wouldn't be concerned if I had noticed this out of the box but I'm still pretty sure its a new thing
