I  lately noticed increased temperature of my netbook. Sensors command gives near 90°C in stress. I decided to replace manufacturer thermal pasta on CPU and clean radiator.

Cleaning CPU unit. Above: the old, hardened, thermal paste on the copper pipe heat sink.

Instructions

Unplug all wires and remove battery pack. Unscrew back plate and delicately remove it. Remove HDD/SSD and RAM and then all other screws around back cover. Using credit card lever plastic hitches around (be careful, they are very fragile, I broke one), starts from these in battery slot. Carefully remove the cover, watch out for plugs. Here is an useful video on youtube showing disassemble process.

You should now have access to whole cooling system (copper thermal wire with fan). Unscrew 3 screw around CPU, unplug fan (I levered it with flat screwdriver, it was attached by weak glue) and remove it.

With cotton soaked in alcohol remove old thermal paste (in my case after a few years after purchase it was a hard layer). From copper wire I scraped it using a credit card. You should see a mirror-like surface with the AMD logo and other chars. Radiator must be properly purge and a fan clean. After evaporation of the alcohol, apply a small amount of paste and using credit card spread a thin layer covering the entire space. I used Arctic MX-2 thermal conductor because it does not conduct electricity and are relatively easy to be applied.

Left: proper amount of thermal paste on the processor. Right: thin layer on GPU(?).

Now, after few week I had temperatures around 50°C in stress.
