Acer :: 5930G Cooling Solution

I got myself 5930G a week ago.

I removed all of the unnecessary programs that Acer put in (they do make decent laptops but really overbload the OS with stupidities) and optimized Vista as much as I could (which is working nicely if i do say so myself ... but I'm still considering on going back to XP SP3 until Windows 7 comes out.).

Right ... I also played Mass Effect for a while on the laptop (maxed out at native res of 1280x800 works without a problem).

Now the only thing is, I'd like to reduce the temperatures of the laptop.
The idle CPU temp is at about 52 degrees, while under load reaches about 72 degrees Celsius (which is pretty good considering the casing).

I will buy myself the ZALMAN ZM-NC2000B cooler ... but what I would also love to do is to undervolt both the CPU and the GPU.

I'm aware the RMClock is not exactly effective when it comes to P7350 cpu.
I tried to undervolt it last night, and as much as I reduced the current going to the multipliers, the temperatures remained the same under stress for prolonged periods of time.

So ... until I find a way to undervolt the cpu and get myself the forementioned cooler, I'd like to undervolt the gpu (9600m GT GDDR3)
If it's possible (and I know it is), I need to know of programs that can be used to acomplish this.

As much as I like my new laptop, it would be nice to further extend it's lifespan (even though it's brand new) and reduce the heat output.

I was also thinking on getting the thermal paste and applying it to cpu/gpu.
Although I'm not sure I want to go ahead with it as I don't want to void the warranty.

how to overclock the cpu/gpu in question without significant gains in temps.
