![]() I was told that the paste need only be the size of a grain of rice. When the laptop has cooled down of course. I wonder if a strategic blast periodically from an airline could solve things so that you don't have to take the heat sink off. The sad thing is that to clean the lap top you are forced to got these lengths to free the trapped dust and (especially) fibers that come from clothes carpets, bedclothes blankets and pets. With it all reassembled (two screws left over.) the lap top had never been so quiet. No wonder the poor thing ran like it did. They were all felted together like a mega lump of belly button fluff. Behold!!! Trapped perfectly between the fan blades and the grill was a huge wodge of wool fibers that covered the whole grill area. Shear nosiness then coaxed me to take the actual fan apart from the fine metal grill on the outlet side. I could then see that the reverse side was still dusty which then got dusted too. So I dived in a little deeper and got a little braver and took off the heat sink off the GPU and CPU - and with that the fan was able to be freed too. Which made me wonder if the fan was at fault. However, when reassembled it made little to no difference. With a hoover and a small paint brush I was able to clean seemingly all the dust off. The whole thing was dusty where muck and fine, fine dust had crept in - especially sticking to the fan. ![]() I was contemplating some severely geeky ideas about cooling the poor thing. Hi - I was gifted a 6 year old HP Pavilion that ran like a hairdryer all the time and was patently working like an old over hot dog. Personally I use the line method and it's shown to work really well. The credit card/card method works best if you apply a thin, uniform layer onto the chip otherwise you will get bubbles in the middle of the new thermal paste after reapplication of the heatsink. Buy Thermal Paste from the best online computer store in S. Various grades of paste are available which have various degrees of heat conduciveness. It is applied between the heatsink and the CPU to fill any imperfections that decreases contact between the two. When you actually re-apply the heatsink onto the chips then you're going to have excess spill along the parameter and be a waste. Thermal paste is an essential component to building or maintaining your PC. Methods differ on how to apply thermal paste properly but it's agreed upon that a small amount is much better than a large amount. The cleaning job you did is not great since you want to remove all the old thermal paste so that the surface of the chip is reflective like a mirror and lint-free. When you remove the heatsink from the CPU or GPU for the first time, make a mental note of where it touches the respective chips and the clean both the CPU/GPU and heatsink spot. As someone who loves building computers and keeping up to date with technology, there are a few things that need to be cleared up from this instructable.
