[mythtv-users] Out of nowhere, cpu is now cooler

I do a lot of nuvexporting of my recordings, always pushing the cpu to 100%
for hours at a time (core 2 duo, 1.8ghz, 800mhz bus).
Usually my cpu gets up to around 45-50 degrees Celsius. My cpu fan, the
stock intel one, usually goes around 2000 to 2200 rpm or so when at this
temp. This has been a constant throughout the last year or so. I check temps
and fan speeds all the time, and they're always around this area.
I recently switched to mythbuntu 8.04, and all of a sudden, my temps never
go above 39 degrees celcius when at 100% cpu usage (100% on each core). The
cpu fan, which is auto controlled by the motherboard/bios, never goes above
1600rpm. It's now hotter in the house than it was 6 months ago. I just don't
I mean, I'm not complaining.I'm even thinking of overclocking it now, but
just don't want to mess anything up.
But how and why could this be? I have always used mencoder to nuvexport my
recordings, and it goes the same fps, if not more now than it ever did
before. I get around 30-35fps transcoding with some good quality settings.
Nothing in the system has changed in the past year except for the fact that
I've added another drive inside it, which I'd think would raise temperatures
if anything. Also, I have a thermometer in the cabinet that encloses the
computer.yes, it's totally enclosed except for some vents in the back, and
that thermometer never gets above 85 degrees F except when it's a hot day.
