Okay I have two suggestions, one to check and one to apply if needed.
First is the Fan1 here your CPU fan? 14rpm is way too low unless you have fan speed control, either way I would suggest you get it up to at least 600 rpm at the minimum so look into that first (you may have to replace that fan).
Second, you may have to clean off and reapply the thermal compound/paste on the CPU, I won't go into detail on how to do this since you should be able to find some good guides with a google search. Make sure you have all you need and know what to do before you attempt this!
