I know it may be a bit late, but just to make sure that there's an answer here for anyone wondering this in the future, I'll go ahead and put the solution here.
There's a program called speedfan that will let you manage fan and clock speed, as well as monitor temperatures of the core(s) of your computer. You can get the free program from here: http://www.almico.com/speedfan.php
Make sure to do some research on how to overclock your computer before you start, just to see what you need to do. Be warned that every computer is different, and finding the best balance between speed and temperature is a process of trial and error. Good luck!
