Same problem here too. * DELL Studio 1557 - (Core i7 @1.60) * 2.6.31-19-generic #56-Ubuntu SMP x86_64 GNU/Linux
The laptop came with Windows 7 installed , and it was totally silent. After I installed ubuntu, things became ...noisy AND hot :) A fan is heard working all the time (very loudly) and the area around mousepad tends to become very hot after some time (2 hours+) I tried changing the CPU frequency and used some certain governors, such as "ondemand", offered by the cpufreqd tool....but nothing changed concerning the fan speed and noise. Notes: ====== - I 've got the A02 BIOS version (10/06/2009) ...but I think it doesnt matter, people with A03 also faced same problem. - also: $ cat /proc/acpi/fan/FAN0/state status: on $ cat /proc/acpi/fan/FAN1/state status: off $ cat /proc/acpi/thermal_zone/TZ00/temperature temperature: 27 C $ cat /proc/acpi/thermal_zone/TZ01/temperature temperature: 55 C I attach my lsmod. ps: I was also told that this could be an issue of DELL, since Windows 7 power management is set to "Balanced", so in case of greater workloads, the fans could then busy noisy too. *The thing here though, is that the fan becomes being noisy since Grub starts loading......
