[QUOTE="iggibar, post: 1821250, member: 97843"] [B]Applying new thermal paste[/B] So, Apple has a history of not using the best quality thermal pastes, as well as doing a horrible job of applying it. I've never been a fan of the all-in-one heatsink setup found in computers like this MBP. I like heat to be distributed individually, but can't do anything about it now. Since the heatsink found on this MBP spans almost the whole width of the MBP and screws down on multiple areas, you need to be careful when removing and screwing it down to prevent excess force to a certain side of the board. Below is a photo showing the screw removal pattern to use when taking off the heat sink. The GPU uses a typical 4-prong plate, while the CPU uses a plate with 2 bow springs to clamp down the heat sink. [ATTACH type="full" alt="20190517_202005.jpg"]37658[/ATTACH] Once you release screw #1 and #2, that will release all tension on the bow springs. Screws #9 and #10 are removed last because they are the main anchors. #10 is last because the whole heatsink has to slide into #10 position for it to go back in. Look at this mess!!:Oops: [ATTACH type="full" alt="20190517_202539.jpg"]37659[/ATTACH] There is so much paste everywhere and it was dry similar to dried up clay! Both the GPU and CPU use a plastic liner as a cover for some dumb reason. There is MUCH more past underneath it that I didn't take a picture of. There should NEVER be enough paste applied that is causes the overflow to reach the capacitors of the chip!

[ATTACH type="full"]37661[/ATTACH] [ATTACH type="full"]37662[/ATTACH] The heatsink slides in at an angle into screw #1's position, and then you lay it down over the other wholes as you line everything up. It's pretty simple. [B]STEP ONE-[/B] Partially screwing down all of the following screws in their numbered sequence: [LIST] [*]Screws #1 and #2 are screwed down as the core anchor. [*]Then followed by #3 and #4 screws on the GPU. [*]#5 and #6 follow to initiate the bow. [*]#7 and #8 are next. Use a finger to press down on the bow while screwing them in. While they are still loose, align both bows so they are centered on the heat sink. [*]Screw in #9 and 10. [/LIST] [B]STEP TWO- [/B]Screw down all screws following their numbered sequence. [/QUOTE]
