View Full Version : [ubuntu] [SOLVED] System Fan Not Coming On

New to Linux & Ubuntu.

I have a Compaq Presario SR1200NX Desktop PC w/1.25GB's RAM & a 40 GB HD. I have an ATI Radeon 9550 Graphics card, but other than that, pretty stock stuff. I'm also using a Viewsonic VA1930wm LCD Monitor.

I've noticed that the System Fan is not coming on. I installed the hardware sensors mentioned in another post. I look at the BIOS on start up, and when in BIOS, the System Fan IS running. Boot into Hardy, no fan. I cannot see a way to set anything in the BIOS for the fan, and the CPU gets up to 140-150 degrees Fahrenheit.

Does anyone have a suggestion on how to get the fan to trigger?

TIA

This is really strange. I've never heard of fans going off while using Ubuntu. I suggest you to take support from HP.

I had a similar problem when I installed gkrellm system monitors, it allows you to control the fan speeds and when I set the temps I set them for Celcious instead of Farenhieght, if you have any monitors or something similar try looking at the settings

Which version of Ubuntu are you using?

Which version of Ubuntu are you using?

Ubuntu Hardy 8.04 Kernel Linux 2.6.24-16-generic GNOME 2.22.1

Haven't found anything that actually allows me to set fan on/off & temp ranges. I've installed Sensors Applet Preferences. Good info, but no control.

BTW, fan was working fine in WinXP Pro SP2 before I junked it and went to Ubuntu.

TIA

I did look at the links provided above, but honestly couldn't determine if any of them pertained to what I was trying to do.

Is there software that actually allows you to control/set the fans?

TIA

For my Acer, I had to install software to get the fans going. It wasn't in the kernel. You might want to search like I did..mine were called acer** fan.bz2. Worth a shot !

I found the following in the Compaq.config file in the acpi-support folder.

case "$model" in
"Armada E500"*)
ACPI_SLEEP=true
;;
"Evo N600c"*)
ACPI_SLEEP=true
;;
esac

Um...Is this what I should be looking into/at, and if it is, what if anything needs fixing?

TIA

Help?

Okay, have done some digging. Looking in my ACPI folder, there are a number of things I don't know what to make of. First, if I look at the Fan folder, there's another Fan folder in it, then a "State" file within that. If I try to open the "State" file, using gedit, there's nothing in the file. I've noticed the same exact thing when opening the Thermal_Zones folder and trying to see what if anything might be in the files in that folder. Nothing. Does this mean anything?

I'm getting this:

cat /proc/acpi/thermal_zone/*/trip_points
critical (S5): 100 C
passive: -248 C: tc1=4 tc2=3 tsp=60 devices=CPU0
active[0]: -266 C: devices= FAN

does this help in figuring out what's happening? Also, Fan 1 isn't spinning up at all. I'm using gkellm tools, and fan1 is at 0, and fan2 is at 2033 (goes a little up and down). Why isn't fan1 coming on?

What happens if you set the critical (s5): from 100 to 60 C? or 50 C? to see if fan will come on when temp gets up to 140F (btw, 140 to 150 F is not especially hot for most CPU's)

here's another thread of interest.

I really hate to show off my ignorance, but here goes...ahem...How do you set the critical (s5) from 100 to 60 C? Too new to Ubuntu/Linux, but a quick study.

thank you very much for the reply!

oh, boy...if I had simply gone to your link first. Let me see if I can get that to work.

Thanks again!

I hear a fan! Thank you so much for your help! Me and my PC feel a lot better now!

And, if you're so inclined, I've got another issue at:

Regarding my monitor if you want to take a stab at that, too!
