[mythtv-users] CPU & CPU Temp

[Mr. Vining]

I've been using Mythbuntu for my front end and I'm loving it.  I'm  
the first of any of my friends to really try Linux, so I'm pretty  
newb. I'm about to build a frontend for my bedroom and living room.   
Sound actually is an issue in these areas so I'm looking to build a  
pretty quiet computer.  I'm looking at:

but I am worried about the heat.  Does Linux / Myth have any tools  
for checking on the temp of CPU and GPU?
