Unfortunately I don't know about the cooler, Is Arctic Siver 5 would be a good thermal paste?not dangerous but too high. Reapply thermal paste and clean the fan/cooler of the CPU
which cooler is it? Eventually you will need to get a better one, which can cool down your 130Watt CPU
Its Taisol 12VDC, here is a ebay link to this hsf.Would use Arctic MX-2 or MX-4.
Arctic Silver is ok if you have nothing at hand, but wouldn´t buy it.
If the cooler is not good, then the heat will not be lower in all cases of different pastes.
Take a picture of the cooler, maybe someone is recognizing the model
