Christopher
make some math with the numbers
multipler x FSB(Front Side Bus) = CPU frequency
12x100=1200Mhz
9x133=1197Mhz
the higher FSB gives a faster system as the speed to the ram memory is faster

I have the CPU and MB and is running at 48 C,
some thing that will make a differens for you cpu temp might be.
1. low quallity cpu heatsink/fan
2. powersupply placement inside your computer housing
3. the design of your powersupply how it moves hot air from housing to the outside
in most cases it is place right above the cpu heatsink wich is great as long it
has a opening in the bottom so that it can pull hot air from the heatsink
4. the amont of free space/air that are cirrculaiting in you housing
5. put some additional fans to pull out hot air and push in cool air to your housing
this can be tricky and need some testing of what combination will be best
and doesnt make to much noise

No the CPU will take what it need or not run at all
what i have seen is that athlon 1200 consume about 110Watts
on its own so if you have alot of disc drive , powerfull videoboard
i think that you should look for a bigger powersupply and if so see 3.
