To disassemble the MSI GP72 Leopard Pro laptop with cleaning and replacing the thermal paste,
I recommend next tools.
Directly you will need a Phillips screwdriver Plastic opening tool
Antistatic brush Thermal paste
Tweezers Thermal pad (if there is a need for replacement)
On the bottom of the laptop, remove all the screws.
Next, take a plastic opening tool and begin to opening the case along of the laptop.
I recommend using a plastic tool in order not to damage the case of the laptop.
Now that the laptop case is open and you need disconnect the battery.
Disconnect the fan cables from the motherboard and remove the wi-fi antenna from the fan
casing.
Now unscrew all the screws from the cooling system.
Pay attention to the order of unscrewing the screws, I recommend repeating in the same
order.
Remove the cooling system from the motherboard.
Take a napkin and remove the old thermal paste from the surface of CPU and GPU.
Also, remove the thermal grease from the radiator.
When removing the cooling system, thermal pads may tear and remain on the motherboard.
There is nothing critical in this, you can take a torn off piece and move it to the radiator.
How to understand need to change the thermal pad or not.
If the thermal pad is in an elastic state, there is no need to replace it; if the thermal
pad is not flexible, it must be replaced.
Now let's cleaning the fans from dust.
Remove the screws on the fan case.
Open the
fan case and inside you will see such a pillow of dust, due to which the laptop overheats
and it cannot be removed by blowing compressed air or using vacuum cleaner, only cleaning
will help here.
Take an anti-static brush and remove dust from the radiator and fans.
In this state should be cleaned fan.
By the way, if you need to replace the fan, for example your fan is very noisy, by this
Part Number you can find compatible fan for replacement.
In the description under the video, I will leave a link where you can buy a new fan.
I also recommend removing dust from the laptop case.
If you decide to clean the dust from the motherboard, this should be done only with an antistatic
brush or compressed air.
Now take thermal grease, in my case it is Noctua NT-H1, but there are also other good
thermal pastes like MX-4 or GD900, I previously tested them and leave the link to the tests
in the description under the video.
Apply a small amount of thermal paste to the surface of the processor and the graphics
processor and spread it in even layer over all surfaces.
Now you can install the cooling system and fasten all the screws.
Pay attention to the order in which I install the screws.
One of the important stages of the assembly is to connect
two cables from the fans to the motherboard.
Install the battery and fasten the screw.
Install the lower part of the case of the laptop.
To turn on the laptop after disassembly, you must connect the power supply.
Turn on the laptop and make sure that everything is working properly, if everything is fine,
you can fasten the screws and use
the laptop.
