Title: Fan control
Post by: siringo on February 17, 2014, 10:52:27 PM
Hello.

My laptop seems to get quite hot during use and the fan doesn't seem to kick in as it used to when I ran Windows.

I've googled the problem and it seems quite a common problem with Linux. I'm hoping some one here can help me out.

I have an HP DV6 Pavilion. The fan is OK as if I shut down Linux, reboot, and break into the BIOS, the fan starts up as it used to in Windows and attempts to cool things down.

Thanks for any help.

I've tried to post the report a few times and I keep getting a server error. I've attached it ..... hopefully.

Thanks for helping. Now I'm not in a noisey server room, I can hear my fan spinning. But earlier today, the fan wasn't speeding up as much as it would under Windows previously.

Thanks for any help.

In that case, use it a bit tonight at home in a quiet environment, and let us know how you get on.

Well the fan is being spun up and down which is great, but it kicks in a bit later than what I'm used to. Is there any way settings for the fan can be altered? For example, is it possible to have the fan speed up at 60c instead of 80c etc etc? Is there a config file that can be altered??

Thanks again.

Try installing psensor, see if this helps.

My desktop computer has crashed a couple of times too. It did not seem to be working to hard.  I had Thunderbird running but don't know if it was checking mail and browsing using Firefox. I have had to unplug it then plug it back in then reboot. I get a message saying that it had crashed due to overheating.

I installed psensor, it just lets you see how hot things are running and alerts you when the temp exceeds a setting you set. It doesn't let you alter any fan or temp values etc.

I installed Pensor. Now I am thinking about the above install too, then cleaning my fan, and activating the firewall as recommended in other posts.

:-\ I am staring to think I am worrying too much and overthinking this stuff too much. I not having an overheating problem often. Maybe I should just stop and enjoy the ride that Linux Lite is providing?

Hello!

Fan control has been an issue with Linux for some time now. Linux is less processor-intensive than Windows, so the fan should run less anyway. (I get more operating time on my netbook's battery; YMMV). When the processor needs cooling, the fan SHOULD come on.

Buy a can of liquid air, spray the fan out, make sure you're not smothering your laptop, and ENJOY. Laptops, especially faster ones, run hot by nature anyway.

Is it an older laptop? You said it's a DV6, so it's probably not. On older laptops and desktops, the paste compound between the processor and the heat sink can break down. If this happens, the PC or laptop will usually shut down on its own after a brief period of time. New paste can be applied, but on a laptop, it must be disassembled to reach the heat sink and CPU.

Additionally, older desktops experience thermal breakdown of the electrolytic capacitors on the motherboard. The innards of these parts swell, split the tops (by design), and ultimately, leak electrolyte, a corrosive substance which smells like ammonia. This can ALSO cause system failure and erratic operation.
