HP G60-125nr Thermal Paste Reapplyed

I have a HP G60-125nr:
AMD Turion 64 X2 RM-70 2ghz
3GB DDR2
250GB HDD
Nvidia Geforce 8200m
15.6" Display

This notebook has been known to overheat. I have heard that reapplying thermal paste helps, so I spent 1.5 hours taking my laptop apart. Very difficult to take apart! Long behold, I found rubber hard cooling paste slapped on there, with the graphics chipset that was attached to the cooling copper with a foam thermal pad.

I cleaned those off and applied Arctic Cooling MX-2 (pea-size method). I put everything back together. Run it, and watch a flash video. Here are the temp averages. (Note: laptop is lifted up on a mesh stand on a flat surface to increase air flow underneath.)

Before:
Idle: 58-70C
Flash Video 480p: 80-105+

After:
Idle: 50-65C
Flash Video: 80-90C

Still gets hot. I have noticed though that it cools down faster after load much faster than before. However it is still hot. Fan is still hot.

Did I do something wrong? Or is my previous suspicions right, that AMD and Nvidia things run hot? And that HP are bad laptop designers?

 

Pea size is a bit much for laptops, but a 10 degree drop in load temperatures is pretty respectable. You could try again with less if you want. Do a bit of testing while your computer is in bits so that you don't have to waste hours putting it back together only to take it apart again. If you try about three applications, chances are you won't get much better than the best of those. Running a computer completely in bits isn't reccomended per se, but provided you lay it on something static free and non conductive like a cotton bed sheet then you'll be fine, it's a little hardcore so don't feel you have to do it if you don't like the idea.

Firstly though, I take it you've cleaned out your heatsink?

 

Yeah, no thanks. I think this laptop is the way it is because the CPU and the IGPU is on the same small strip of copper. Thus together they generate a lot heat.

Yes, heat sink was cleaned spotless.
