Replacing the RTX A2000 heatsink isn't rocket science, but we're dealing with expensive hardware so follow these steps carefully.
You should've received the heatsink along with some accessories. Make sure the box contains the following:
- Thermal pads for the memory
- A bag of screws:
- 2x M2.5x10mm spring loaded screws for attaching the heastink to the PCB
- 2x M2.5x6mm screws with bolt to attach the PCIe bracket to the PCB
- T6 and T8 screwdriver
You will need to provide for yourself:
- Philips screwdriver
- Thermal paste of your choice
1.Remove the PCI bracket screws
The first screws to remove are the two screws that hold the PCI bracket to the shroud. They are both T8 screws, which is the largest screwdriver of the two included.
Don't pull off the PCI bracket just yet as it's still fixed to the PCB.
2.Remove the shroud
To remove the shroud, we need to unscrew all screws apart from the ones in the backplate (the retention bracket). They are all T6 screws.
Unscrew the right two screws first as the are the ones still keeping the PCI bracket in place. You can take off the bracket and then unscrew the rest of the screws.
Lift the shroud a little bit and carefully detach the fan header. This may require small pliers. When the header is detached, you can take off the shroud.
3.Remove the stock heatsink
The heatsink is attached with two T6 screws in the backplate. When unscrewing those, be wary that there is quite some force on the backplate and it springs back when it comes loose. You may want to hold it when unscrewing the first screw in order not to damage things. When the second screw is loose, you can take off the heatsink. It may be glued to the die due to the thermal paste, carefully tilt it to the left and right until it comes loose in that case.
3.Clean the die and memory
Wipe the original thermal paste off the die using a lint free cloth. Clean the die using a bit of Isopropyl.
The original thermal pads are bad and should be replaced too. They are brittle and probably come off in multiple pieces. You can use some Isopropyl here too.
4.Thermal pads and paste
Put a small drop of thermal paste on the die and put the thermal pads on the memory chips. The pads are already cut to size but don't forget to take the plastic off.
5.Attach the new heatsink
Important: If you have the aluminium version of the heatsink, complete step 6 before you start step 5.
Lay the heatsink upside down and put the PCB on it, also upside down. Compare the caps and chokes on the PCB with the cutouts on the heatsink base so you don't put it upside down (it would be impossible to mount anyway).
We will not be using the original backplate anymore. Insert the spring loaded screws through the pcb and screw them into the heatsink. You should screw them in until you can't go any further, but don't put excessive force on it so you don't damage the threads.
6.Attach the PCI bracket
The PCI bracket initially mounted to the shroud but the shroud is gone now. I've provided two M2.5 screws and bolts to attach the PCI bracket using the original mounting holes.
You are now ready to enjoy an inaudible RTX A2000 inside your Yocto! Just add two 60mm fans and control them based on your GPU temperature using Fan Control. Read all about it in the GPU deshrouding guide.
