CPU Tempreture

It depends on which kind of CPU we are talking about. There are some where it is normal to run that hot, ie. Intell Prescott, or the old AMD K6-2 and some of the AMD XP.
We need to know which CPU you have to be able to help you

I'd say that's above the normal temperatures for that core.
Meaning, it won't damage the cpu but lower temperatures are common for this low voltaged cpu.

You have to remember that although 50degrees is quite hot, I believe AMD CPU's have a thermal ceiling of 75degrees (although running it close to those temps for long periods of time would not be recommended). The other thing you have to realise is that temp sensors on motherboards are not calibrated, a temp sensor on one motherboard might read as CPU as being 45degrees while another board could read the same CPU (and cooling solution) as reaching 50degrees.

*rolls eyes* all these posts about "is my cpu too hot"
