Dell Inspiron 1525 CPU Temp Problems

I noticed that my CPU was reaching critical temp from dmesg | tail and I didn't know why because I wasn't doing anything CPU intensive. I installed lm_sensors and I get this output:

acpitz-virtual-0
Adapter: Virtual device
temp1:       +47.0°C  (crit = +85.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +58.0°C  (high = +100.0°C, crit = +100.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +58.0°C  (high = +100.0°C, crit = +100.0°C)  

I have been looking around but I cant find a way to change the high value to something lower (I'm assuming that if I do that the fan will speed up earlier as it barely turns on right now even when the temp is in the 70s and 80s)

Also I just noticed this in dmesg

coretemp coretemp.0: TjMax is assumed as 100 C!
coretemp coretemp.1: TjMax is assumed as 100 C!

I'm not sure what this means but I would like my laptop to run a little cooler...
Thanks in advance!

Re: Dell Inspiron 1525 CPU Temp Problems

See here for instructions on setting up CPU frequency scaling, which you absolutely want on a laptop to save power and keep it cool (you may want to lower the up_threshold down to something like 15 to avoid a performance loss).

There's a few dell packages in the repos and the AUR and one of those might help you control fan speed (you could also check the BIOS).

Re: Dell Inspiron 1525 CPU Temp Problems

Thanks I will definitely set up the scaling and i will check the AURs.

I tried to look through the BIOS but I was unable to find anything about the fans... Hopefully I will find something useful in the AUR

Thanks!
