[mythtv-users] OT: MB Temps w/ AMD785G Chipset

I believe this is normal for northbridge with video and passive
cooling. My passive cooled nVidia 8400 GS runs hotter than that.. I
actually have that exact board here at work however its running
windows xp and I am not sure I have the monitoring software installed.
