DQ45EK - High Frequency Noise from VRM ?

Hi,

Anyone else noticed this on DQ45EK boards ? Especially when using fairly low power processors such as Celeron ?
I think its coming from the VRM and its the sort of noise that could drive a dog crazy, very high frequency whistle/whine/buzz that occaisionally changes slightly in tone.
It sounds as if its coming from around the VRM area on the mainboard.
