A quick look around the graphic card.

Supplies

T10 Screwdriver

T6 Screwdriver with some kind of leverage (hole thru the handle, mine has a 7mm A/F hex)

Plastic hooked scraper

Plastic hooked pointed scraper

Isopropanol

Cotton buds

Strong paper towel

Magnifying glass

Remove the Mounting Plate

The mounting plate is attached by way of 6 screws.

4 off M2.5x4mm T10 CSink (Flat) Head Screws attach the plate to the chassis.

2 off M2x5mm T6 Wafer Head Screws attach the plate to the chassis thru the PCB.

Remove them all and the plate will come off.

Remove the Chassis

Remove the 7 off M2x5mm T6 Wafer Head Screws that attach the to the chassis.

Remove the 3 off M2x5mm T6 Wafer Head Screws that attach the fan assembly to the chassis.

All need to be removed to release the chassis.

For tidiness, attached the mounting plate back onto the chassis.

A Quick Look Around the PCB, Heatsink & Fan Assembly.

Seperate the Fan From the PCB

The fan isn't mechanically attached to the PCB.

Pull out the fan power connector on the side.

Release the main power connector from the fan assembly (light adhesive).

For tidiness, attach the fan unit back onto the chassis.

A Quick Look at the Power Connector

Remove the Heatsink Backplate

040 - Heatsink Backplate Removal.jpg

The backplate is attach using...

4 off M2x3mm Wafer Head Shoulder Screws (Ø2.8x3mm)

Do not remove each screw in it's entirety. Loosen one scew slightly and move onto the next and so on and so forth until all screws are fully removed.

Remove the Heatsink

Hold the PCB in one hand and the heatsink in the other and start, gently, applying rotating pressure, back and forth, to the heatsink around the axis perpendicular to the GPU to heatsink contact plane.

The heat transfer paste will become more and more plyable and the heatsink will be able to rotate back and forth by a couple of degrees.

After that... place a plastic tool between the heatsink and PCB in the corner shown. Use this as a lever and gently pry the heatsink off. The heatsink should release without bending the PCB.

Clean the GPU

Using isopropanol, cotton buds, strong paper towel, plastic scraper and a magnifying glass carefully remove all of the heat transfer paste from the GPU's area.

Beware of the tiny components around the GPU as these can be easily popped off.

Soak the area with isopropinol.

Use a scraper to lift the heat paste overflow by aiming for the corner between the chip and PCB.

Then using a pointed scraper remove the paste in between components.

the highest component on the PCB around the heatsink mounting area is 2mm.

Appendix... Model the PCB With Important Sizes

Scans were taken of the card.

The PCB was modeled in Solidworks and the scans were overlayed.

Some important chips were added, along with the backplate and the main connectors.

Some important sizes were taken.

The GPU PCB measures 50.98x50.98mm with a 3x45° chamfer on the top left corner

The mounting hole pitch is 67.54x58.72mm with 4 off Ø3.8 holes.

The GPU chip measures 26.8x23.4mm.

The GPU contact face is 2.81mm above the PCB.
