Hello There, would highly recommend this product. Got my Raspberry Pi overclocked to 900MHz processor side and the temperature remains betw. 51 and 53 degrees Celsius. The warranty does not go the way lost, as long as one does not increase the voltage recording. Glue was not an issue and also keeps all reliable. But if you want even more cooling should remove the pads and glue the heatsink directly, with thermally conductive adhesive, on the chip. Caution, because the chips are very small enough a pinch of thermally conductive adhesive is applied to the center on the underside of the heat sink. By placing on the chip, the adhesive is distributed over the entire surface of the chip.
