I am running an Ubuntu 11.10 Beta2 Wubi installation on my Samsung 900x3a notebook. I had to try it with wubi because this darn thing just won't boot off usb drives (even using the port on the right side). But this is another story.
First thing I noticed was that the fan doesn't go into an idle state. It's always spinning on full power. The System Monitor shows an evenly distributed usage of all 4 virtual cores.
But what is actually looking very suspiciously to me is the output of lm-sensors:
Adapter: Virtual device
temp1: +62.0°C (crit = +100.0°C)
temp2: +29.8°C (crit = +100.0°C)
As you can see, it seems like one core is not getting enough air. Or to name another possibility maybe one core isn't (fully) used by the system?
On Windows 7 I usually get around 55° C to 68° C (only when the CPU usage is near 100 %)
Does anyone have similar problems or maybe even a solution to get the temperatures leveled and therefore to get the fan go idle?
