Here's a bit of an odd issue. It's not a problem per-se, but I'm hoping to get a bit of community feedback on this. Whenever my GX740 notebook has a USB device attached to it, the CPU temperature, according to CPUID's HWMonitor program, is about 2-5 degrees higher than when nothing is connected. It doesn't matter if the device is a thumb drive, Xbox 360 controller, mouse, keyboard, or printer. It also only seems to happen with USB devices, as the external hard drive I have plugged into the eSATA port does not cause these increases.
My system has the latest BIOS, version 1.0B posted on the MSI site a few days ago. The chipset driver is the one from the MSI site, version 184.108.40.2067.
The system operates normally otherwise, but my wife's AMD-based Toshiba laptop doesn't experience this issue. Any insight is appreciated.
