CPU heats up on file copy/backup and fan speed does not increase

Hi Friends,

I have been having issues with fan in my Dell Studio 1555. It has an ATI Radeon card and I had installed the proprietary catalyst driver as the open source driver is too noisy.

Recently, I noticed that on accessing my hard disk and copy files or running backup (luckybackup), the temperature shoots up from around 60 deg C (just using chrome) to 100 deg C when it would shut down itself. However, it seems like the fan speed does not increase with the increase in temperature to help it cool down.


I tried to get the fan speed details with "lm-sensors" but it would not show the fan speed. Here is the output of sensors:

[user@domain]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +60.0°C  (crit = +100.0°C)
temp2:        +59.0°C  (crit = +100.0°C)
temp3:        +66.0°C  (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +58.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +58.0°C  (high = +105.0°C, crit = +105.0°C)

Following the Arch wiki, I added acpi_enforce_resources=lax to kernel parameters but it did not help as well.


Here is the main problem:

1. CPU temperature shoots on accessing hard drive but fan speed does not increase - Any guide/direction to investigate would be really helpful.

2. Sensors does not show the fan speed. Read about i8kutils, but couldn't figure out how to get it working with systemd. Any indicators here?

The fan was bad. I had to replace the fan. However, I have not been able to figure out how to see fan speed in sensors.

I don't know if you tried this yet, but the sensors command will show you almost nothing unless sensord is running.
