Have (But please use thermal grease chipset, among others, for CPU) the pad even at 3 laptops), 1 motherboard (chipset, voltage transformers, ...) and 2 graphics card (RAM modules) used. Laptops running again quietly :) ... Unfortunately, brand manufacturers such as motherboards using cheapest thermal pads, so I often replace these, either directly to the beginning (if the system will be overclocked), or after a time when even a "major cleaning" the system is present :)
A little tip: I would as far as possible always cut it to size the pad on the chip size, first, it will save you material and secondly, then swells unnecessarily the pad side out (without any contact with a heat sink, a pad then have an insulating effect may on the sides , very bad;))
After continuous use, I will complete my review here (if the pad is still elastic, for example)
