Any update on this?
I have a Dell Studio XPS 1645 with Core i7 720QM and Ati Radeon HD4670
graphics. I tried installing 64-bit versions of Ubuntu 10.04.4. 11.04.
11.10. 12.04 but almost same temperatures and fan state in all.
Installing the latest proprietary driver (catalyst 12.2) helped me reach
the following levels, from 10 degrees above these (currently on Ubuntu
11.10 Gnome Shell Remix):
========================================
k4rtik@PlatiniumLight:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +26.8°C (crit = +127.0°C)
temp2: +66.0°C (crit = +85.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +65.0°C (high = +84.0°C, crit = +100.0°C)
Core 1: +65.0°C (high = +84.0°C, crit = +100.0°C)
Core 2: +65.0°C (high = +84.0°C, crit = +100.0°C)
Core 3: +66.0°C (high = +84.0°C, crit = +100.0°C)
========================================
========================================
k4rtik@PlatiniumLight:~$ aticonfig --od-gettemperature
Default Adapter - ATI Mobility Radeon HD 4670
Sensor 0: Temperature - 68.00 C
========================================
========================================
k4rtik@PlatiniumLight:~$ sudo hddtemp /dev/sda
/dev/sda: ST9500420ASG: 49°C
========================================
These are similar to what I get in Windows, but still slightly higher.
