and i use Arch Linux 64 bit:

Code:

whit gnome 3.2.

This is my rc.local script:

after 30 min in idle state, this is my sensors:

Code:

[root@myhost pasquale]# sensors

acpitz-virtual-0

Adapter: Virtual device

temp1:        +26.8°C  (crit = +100.0°C)

temp2:        +0.0°C  (crit = +100.0°C)



radeon-pci-0200

temp1:        +64.5°C  



coretemp-isa-0000

Core 2:      +52.0°C  (high = +95.0°C, crit = +105.0°C)

while using only facebook chat (system load<5%):

Code:

[pasquale@myhost ~]$ sensors

temp1:        +26.8°C  (crit = +100.0°C)

Adapter: PCI adapter

coretemp-isa-0000

Adapter: ISA adapter

Core 0:      +73.0°C  (high = +95.0°C, crit = +105.0°C)

Core 2:      +72.0°C  (high = +95.0°C, crit = +105.0°C)

On windows, this temperature is reached while using flashpalyer and some other application.

is there someone can help me?
thanks!
