thickness ? best is first assembly + hard paper"0.5mm" on cpu / gpu ,.,.and VR or VRAM - kid toy "modeline"
after this disassembly + measurement
,.,.or check actual pads + measurement
must have printed HW on pads
and i recommend TG 8 "thermal grizzly" or better pads
alphacool 11 -better "but more cost"
need any soft pads ,.,.not only W_mk is decisive
