Undervolting duo core cpu and fans?

COuld someone please post a tutorial on how to undervolt the cpu on a duo core notebook. I have a w3j and it tends to run quite hot and the fans are on quite a bit. I was hoping I would be able to undervolt it as I have heard that it helps with those things. The only problem is I have no idea how to undervolt the cpu. I have seen posts about how people have undervolted their PMs but I havent seen the process of how to undervolt a duo core. I have seen posted values for the duo core that people have tried but I dont understand them at all. If someone could post a little mini-tutorial of how to use NHC to do this- or any other program- to do what I am trying to do, i would be extremely appreciative.
thanks in advance
Dan

I'd also like to hear an answer to this, since I have a W5F with a core duo and I don't know how to undervolt this thing either

 

Nevermind, I found an answer!

apparently some people have been using a program called RMclock

 

Here's a tutorial on how to undervolt (try using it on a core duo I guess... but be sure to read my previous link beforehand)
