                   exceeds 47.0° C for a short time. It has survived
                   this for about a week with no indication of a
                   problem other than the annoyance of the fan noise
                   and it is probably the quietest of the computers in
                   this room but it has aroused my curiosity.

                   Has anyone else observed anything similar?

                   I've been using this computer for 3+ years and know
                   what is normal for it.

                   uname -a  shows:

                   Linux box1 2.6.18-1.2200.fc5 #1 Sat Oct 14 16:59:26
                   EDT 2006 i686 i686 i386 GNU/Linux

                   It's an old Gateway E-4200 with a PIII 450 mHz
                   processor and as much RAM as it can handle, 384 megs.

                   Any words of wisdom will be appreciated.

Hi Bob,

Written for another, have little time.

Hopefully a place to start, hope helpful:


# This was found adding FC5 to the search and references FC5 -

               Interesting but apparently not a factor:
               /usr/sbin/pwmconfig: There are no pwm-capable sensor
               modules installed

               both of those references refer to "fan control" which I
               apparently don't have available or is not being enabled?

               I believe the fan is being turned on because something
               is becoming hotter since this kernel update.  The 47°C
               temp1 indication is about 5°C higher than it has been in
               the past.

               This system is up to the minute on updates via yum.

               I did look at the BIOS utility earlier in an attempt to
               see what temp1 is indicating but found nothing in the
               manual, on the Gateway pages, or in the BIOS data about
               that.  I believe there was an entry for fan operation
               and will have to shut down again to look at that.

               Thanks for your prompt response.


I would:

1. Grab any updates over the Internet.
2. Google the specific name of the machine with "fan control" and any
other keys that occur to me along the way.
3. Figure out a way to determine if the fan control application is
talking through the BIOS with the fan.

Good Hunting!
