Hi everyone, welcome to HowFixit. In this video guide, I gonna show you how to
disassemble the MacBook Pro 15 model A1398 ( Year of release 2013, 2014, 2015), clean
it from dust and replace thermal paste.
To disassemble MacBook Pro 15 model A1398 you will need the following tools:
Screwdriver set Pentalobe 1.2mm screwdriver
Torx T5 screwdriver Plastic opening tools
Tweezers
Antistatic brush Thermal grease
I also recommend using a magnetic mat during the repair process, which is especially useful in case
of MacBook Pro 15 model A1398. Throughout this disassembly, keep track of each screw so you can
put them back in the right places - this will help successfully reassemble your device. And
don't worry about losing any of screws, all of them will definitely remain on the magnetic mat.
In the description, I left links where to buy all necessary tools.
Turn the laptop over and remove all the screws on the bottom cover.
Disconnect the battery cable from the motherboard.
Use only a plastic tool to lift the battery power connector.
Use only an anti-static brush to clean the motherboard from dust.
Now let's begin removing the cooling system.
Let's begin cleaning the cooling system from dust. Remove all dust from the heatsink and fan.
Remove all screws on the cooling system.
Now you can remove the cooling system by lifting up from the motherboard.
Remove the old thermal paste from the CPU and GPU as well as from the heatsink. If the thermal
paste is very dry and difficult to remove, you can use isopropyl alcohol to wipe the paste.
How to apply thermal grease. Apply a small amount of thermal paste to the CPU,
then take a plastic tool and spread it evenly over the entire surface of the chip.
If you still don’t know which thermal paste to choose for your laptop, in the description, I left
a link to a video where I test different thermal greases and choose the best one for the laptop.
If your MacBook Pro 15 is still overheating after cleaning and replacing the thermal grease, I
recommend watching my video about the cooling pad for the laptop, or how to undervolting CPU and GPU
to reduce heat and increase laptop performance. All links you can found in the description.
Well, that's all, you were on HowFixit and see you guys next time!
