Hello everyone and Welcome to HowFixit In this video I gonna show you how to disassemble
the Dell G5 5587 laptop, clean it from dust and replace thermal paste
To disassemble Dell G5 you will need next tools:
Phillips 1 screwdriver Plastic tool
Thermal paste Antistatic brush
Tweezers In the description, I’ll leave links where
to buy all the necessary tools I also recommend using a magnetic mat in disassembly
process and laying out each screw step-by-step during disassembly, which is especially useful
in the case of the Dell G5 5587 This laptop has a lot of screws of different
sizes and it is very important not to confuse them during assembly
Turn the laptop over and remove screw on the bottom cover
Next, take a plastic tool and begin to open the cover
Disconnect the battery cable from the motherboard Remove the battery, hard drive and m2 ssd
Now disconnect all the cables
Let's begin to the removal of the upper panel on the case
This panel is quite rigidly fixed to the case, so you will have to make a little effort to
remove this panel
Now remove all the screws on the case Again take a plastic tool and open the case,
separating the bottom cover from the cover with the keyboard
Now let's begin to the removal of the cooling system
Pay attention to the order of removing the screws
I recommend unscrewing in the indicated order
The cooling system can be removed from the motherboard by lifting up
Remove the old thermal paste from the surface of the CPU and GPU, as well as from the radiator.
If thermal grease is very dry and doesn't rub well, you can use isopropyl alcohol
Now let's begin cleaning the cooling system from dust.
Remove all dust from the radiator and fan If the fan is very noisy or does not work
at all and you need to replace the fan, you can find a compatible one for the replacement
part number DC5V 0.5A FJQT And also in the description under the video
I left a link where you can buy a fan for Dell G5 5587
If you still don’t know which thermal grease to choose, in the description, I left a link
to the video where I test different thermal greases and choose the best one for the laptop
I mainly use Arctic MX-4, Noctua NT-H1 or GD900
How to apply thermal grease Apply a small amount of thermal paste to the
processor, then take a plastic tool and spread it evenly over the entire surface of the chip
How to understand, if it is
necessary to change the thermal pad If the thermal pad is in an elastic state,
then there is no need to replace it, if the thermal pad is already withered and tough,
then it needs to be replaced Now you can install the cooling system and
tighten all the screws Please notice how I tighten the screws on
the radiator It is necessary to tighten the screws evenly
on each side, a few turns of each screw If you tighten the screw immediately and completely,
there is a chance that you may damage the processor chip
If your laptop is still overheating after cleaning and replacing the thermal grease,
I recommend watching a 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!
