                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.

                Bob
