Description: brand & high quality. Features: Change the mirror pure copper for shell to for Intel CPU: the temperature will drop about 9 degrees. Has been passivated,will not be oxidized and corroded anymore Perfect compatibility with LGA 115X CPU When buying, please pay attention to CPU model. The six generation, seven generation and eight generation U cover thickness is not the same as the three generation and the four generation. Please pay special attention to it.;The positive and negative surface mirror polishing, can be used directly. Tips for Use: The cover is recommended to use 704 or 922 glue (not double-sided glue), which can be used not only to bond the cover and the base plate (to prevent movement), but also to fill the small for gap between the frame around the cover and the base plate; the surface area of the cover is slightly larger than the , increasing the contact area with the bottom of the radiator, increasing its conductivity. At the same for time, the surface of pure copper is equivalent to removing the nickel-plated layer on the cover (the nickel thermal conductivity is lower than copper), and the mirror treatment on the top and bottom surface of the cover, together increasing its thermal conductivity, to achieve better thermal conductivity; in addition, for the for protection of the cover print when used by scratch discoloration blurred, the copper cover is also the same. A good choice, replace the top cover can be sealed, then replace the top cover sold to maintain a relatively color.
