HP/Compaq :: Undervolt Turion X2 RM-72

i'm having major heat problems with my DV4 1220US, If I let my CPU use 100% it shoots up to 80+c on Idle, 105c Under load. The HDD is usually over 55c idle, 65+ under load.

It's ridiculous considering how cool it is in my apartment, and how I balance the laptop on my right leg, with the whole left side uncovered and allowed to freely vent air.

I made a power profile that locks the CPU at 75% this helps majorly, however the Default "low power" setting @ 50% is impossible to use this computer with.

Is this because AMD processors suck? Could that be why the C2D version of this laptop with identical specs costs $200 more?

I tried to undervolt it with RMClock but it wouldn't let me change anything. There is supposed to be an advanced tab for messing with the voltage but it wasn't there. I was using the latest version of the program, and had all my drivers up to date with a super fresh install of Vista.

Is there anything special I need to do to get the program to work with a Turion X2 RM-72?
