Fan/Temperature Problems

Ever since I installed Archlinux (about a month now), the fan has been going crazy. I did a little searching on the forums here, and I installed the CPU Frequency Scaling (http://wiki.archlinux.org/index.php/Speedstep) and that calmed it down somewhat, but now I am afraid of turning down the fan if there really is a need for it. Which program will tell me the temp of the CPU? I have seen references to something called Conky, but thats it.

Re: Fan/Temperature Problems

First you need to install lm_sensors, then once it's configured you can use conky or some other front end (or just the sensors command) to see the temperatures.

Re: Fan/Temperature Problems

Thanks. I installed, and this is what I got.

bash-3.2# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +47.0°C  (high = +100.0°C, crit = +100.0°C) 

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +47.0°C  (high = +100.0°C, crit = +100.0°C)

Should the fan be running at this temp? Should I disable the speedstep and let the fan run at full speed for this temp?

Do you have xf86-video-ati installed? You fan keeps running might be caused by these open source drivers. In my box, fan keeps running when using radeon/radeonhd driver. Using fglrx doesn't have this problem.

Re: Fan/Temperature Problems

i have an nvidia graphics card (GEForce 8300 i think...). I am getting temps of around 55 C now, and the fan is still running at a pretty high speed. I did some more research and some people were saying that you can edit fan settings in the bios, but i could not find that. any ideas????
