Hi! I received my SP3 (i5, 256GB) this week. After the first startup I had to install several Windows 8.1 updates (~1.2 GB). After starting the download and installation the fan goes up and the back is getting "very" warm. BUT shortly before updating is finished the SP3 shows me thermometer picture and shuts down! Is that normal? I didn't read anything about this issue on an i5 device. Just thought only i7 devices are affected.
