====== Laptop Repaste Guide ======
Where we are going we don't need thermal pastes, we got thermal pads!

  * Prolimatch Pk-3 Nano Aluminium
  * Phobya Nanogrease Extreme

===== Application Method =====

  * Cut the pad size a little bit bigger than the die size of CPU and GPU.
      * Check online for exact dimensions of the CPU and GPU die.
  * Apply like a screen protector (the pad might have protective plastic on both sides) on the die itself. (//Check online for screen protector application tutorial before starting here//)..
  * Ensure there are no bubbled in your application.
  * Screw Heatsink back in (//make sure to do only one turn per screw in order dictated until every screw is tightened//).

===== After Application - Mounting =====

  * Make sure the application of the paste / pad is right before the Heatsink is mounted.

  * It's not just the screw order that matters, but how you start screwing in the first place:
      * The key is to turn the screw oppossite way until you hear an audible "click" ( This ensures the screw threads are properly seated).
      * Do this for each screw when barely starting your turns.
      * Lastly, follow the one turn per screw protocol.


===== Mounting Screw Order =====
{{ :laptopwiki:guides:tweaking:l5p_screworder.png?500 |}}
  * Every laptop has its own screw order. Make sure to first open your laptop and have a look on the heatsink for numbers engraved on the heatsink. Take a picture and mark them to see what order they have.
  * Make sure to always follow the order depicted in the heatsink for optimal mouting pressure being distributed equally among the whole heatsink.
      * Not following the screw order will lead to huge differences in temperature delta between cores, which in the end will make some cores throttle, while other cores will stay cool.

===== Liquid Metal =====

  * Liquid Metal is another thermal compound that could be used instead of a normal thermal paste / pad. In order to know more about liquid metal, check these two videos

  * Very dangerous and finnicky. Not recommended for devices that move a lot.
  * **USE AT YOUR OWN RISK**
