I've noticed something about my system when I plug in certain types of USB devices. The CPU temp goes up between 5-7 deg C when I plug in a USB Flash Stick or a USB CD-ROM drive.
I've read something about the USB polling bug on Windows systems and I've tried this
work-around, but still my CPU temp goes up as soon as I use the said devices. Once the USB devices are removed, the CPU temps go back down to its normal idle values. Oddly enough, if I plug in my Digital Camera, the temperature doesn't increase...
Is this normal?
