Welcome to HowFixit, in this video I will show you how to disassemble a NVIDIA GeForce RTX
3070 Founders Edition graphics video card, clean it from dust and replace
thermal paste. This will help prevent the graphics card from overheating.
To disassemble GeForce RTX 3070 you will need next tools:
Phillips 1 screwdriver Torx T5, Torx T6, Torx T8 screwdriver
Tweezers Plastic opening tool
Anti-static brush Thermal paste
Also I recommend using a magnetic mat in repair process and laying out each screw step-by-step,
which is especially useful in disassembly process. The screws can be of different
sizes and when reassembling, it is very important to fasten screws into
right place. In the description, I left links where to buy all the necessary repair tools.
Press on these metal holders and the metal frame is removed from the heatsink.
This ribbon cable is glued to the heatsink, be careful,
use a not sharp plastic tool when peeling it off.
Please note: how I remove the screws on the metal bracket.
It is necessary to remove the screws evenly on each side, a few turns of each screw.
Now remove the old thermal paste. If the thermal paste is very dry and does not rub off well,
you can use isopropyl alcohol. Isopropyl alcohol is completely
safe for the components of the graphics card board, so you can safely use it.
To clean the main board from dust, use only an antistatic brush, otherwise,
when using a regular brush, there is a risk of damage to the board by static discharge.
How to apply thermal grease. Apply a small amount of thermal paste to the GPU,
then take a plastic tool and spread it evenly over the entire surface of the chip.
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 graphics card. Also in this video, I compare the effectiveness
of thermal paste and liquid metal. I think you will be interested to know the result of the test.
Please note: how I tighten the screws on the metal bracket.
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 risk that you may damage the GPU chip.
On this step repair is complete, I hope this video was useful to you and see you on HowFixit.
