The temperature that is reported isn't 100% accurate since heat has a 
nasty habit of not being uniform across an entire component. Anytime I see 
a CPU that is over 35C at idle, I consider that cause for concern. 
Granted, CPUs can generally work fine all the way up to 70C; if you keep 
it at 35C then the other hotspots you can't see won't be so high that you 
have problems. Ensuring that you have a good amount of active 
front-to-back airflow will go a long way to getting the machine cooler. In 
one instance, I had a CPU that consistently ran at 54C-56C at idle. After 
taking off the heatsink and using a dremel to clean the contact point 
really well and using some Arctic Silver 5 thermal grease, I saw a 20C 
reduction at idle.
