With all the changes I have done I say go for it. I have pulled more chips and board solders then I can remember even on macs lol.
Anyway just use some Artic Silver 5, check your current cooling make sure its clean and you should be fine.
The cooling on the eMachines M6805-m6811 series was perfect and the chip went from 3000+ to 3400+ without skipping a beat. Using Artic Silver 5 it ran almost as cool as before.
Personally its not something that bothers me so I say why not. However if the graphics card is the 440 nVidia I think it is then its not worth it as you bottleneck is the GPU.
Anyway Again I say go for it its fun and its custom fit for you.
(If you check the hard forums on the laptop mentioned above you will see it got awsome reviews for over a year which is unheard of with PC laptops it was actually about 2.5 years. And its still considered a great laptop. I know it can go further then the 3400+ as I have a friend locally who has used the new Processor cores with it however I can not speak for exactly what he used... I am adhd and I was not paying atten at the time as I was distracted by..... the opposite sex lol)
If it is the 440 nvidia check out the m6805 and up on eBay they are about 500-800 and have a ATI 9600 that OC's Well beyond anything normal. They really were a great laptop. Played Doom 3 very nicely. I seem to remember the Aquamark3 Bench stock being around 28k and OC's I got a 31k I believe.
