I am with the same laptop and I have the same problem. I didn't manage to install sensors correctly. I installed windows 7 on it and the fan doesn't run at maximum speed.

It took me quite a while for me to figure out a good setting for it, and here is what I am using: # Switch to state(1) on 55 celsius set config(0) {{-1 0} -1 55 -1 55} # Switch back to state(0) on 48 celsius # Switch to state(2) on 75 celsius set config(1) {{-1 1} 48 75 48 75} # Switch back to state(1) on 60 celsius set config(2) {{-1 2} 60 128 60 128} If you did not manage to install the sensor correctly, please open another bug for it. We need to push this issue further. Hello, It's been quite some time without an answer. Now I'm running with: 3.6.8-2.fc17.x86_64 And I am *still* seeing this annoying behaviour. I've been using i8kutils since I opened this bug report, and the software does a good job at keeping the cooler quieter, but unfortunately it is not as complete as one might expect: you can only configure 3 different speeds with it (see comment#2), and it takes some time before you figure out the right values for temperatures. Anyway, this is a ping to see if we can move this issue forward. Please let me know if you need more recent data about my system. Thanks. Same problem with latest update (3.7.5-201.fc18.x86_64). Tested in win8 and the fan is mostly time off Yet another update. Now I am using the kernel version 3.7.3-101.fc17.x86_64, and I still see the problem. As I said in comment#3, i8kmon is not a good solution because it has only 3 pre-defined different speeds for the fan, but to make things worse, I found that it has a bug when the computer goes to sleep state and then gets back from it (but this is another issue with another package, of course). Anyway, is there any other kind of input that I could provide to make the resolution of this bug easier? This issue is *pretty* annoying, it makes the battery life very short, so let's try to get this solved, please. I am changing the priority to "high" since it is affecting me badly these last days... Yet another update. Still with kernel 3.7.3-101.fc17.x86_64. When I suspend to RAM and bring the machine back, the fan becomes much more active. The temperature is always near of above 62 degrees (celsius), though the CPU load is the same as before the suspension. I really can't tell why it acts like this. If I reboot the machine, the fan goes back to the "normal" state, i.e., at level "1" (between 48 and 67 degrees) on i8kmon (CPU load still the same as before). According to <https://bugzilla.kernel.org/show_bug.cgi?id=57051#c6>, there is nothing that can be done in the Linux kernel in order to fix this bug. IIUC, this is a BIOS issue. FWIW, updating to the latest available BIOS from Dell (version A09) didn't fix the issue. I'm closing this bug as CANTFIX because of that. I will still keep an eye on this issue, since it it *very* annoying. |
