I'm planning to repaste and replace the thermal pads on my Gigabyte Windforce RTX 2080 Ti later today. I have a phase-change thermal sheet and new pads that I can cut to size, and I'm picking up cleaning supplies before I start. Are there any easy-to-miss precautions or common mistakes I should know about?

Be gentle with the fan connector and use a plastic tool or your fingers rather than anything sharp that could scratch the PCB. Before separating the cooler, check that every screw has been removed. If the old paste has hardened, gently warming the heatsink with a hair dryer can soften it and make removal easier. When lifting the PCB away, use a gentle rocking motion near the center instead of pulling up from the ends, since leverage can flex or damage the board.
Measure the original thermal pads carefully and match their thicknesses. A single graphics card can use several different pad thicknesses, so a caliper is useful. Pads that are too thick can prevent the cooler from making proper contact with the GPU die, while pads that are too thin may not cool the memory or VRM components properly.
That makes sense. I’m picking up a caliper and have a variety pack of different pad thicknesses, so I’ll measure everything before cutting.
For the phase-change sheet, briefly chilling it can make it easier to handle and cut cleanly. Cut it slightly larger than the GPU die so the entire contact area is covered, but avoid leaving excessive material that could interfere with the surrounding components or cooler mounting.
I’ll definitely double-check the screws and take it slowly around the fan cable. Thanks for the warning about lifting from the middle.
