guide is completely wrong
FIRST OF ALL :
Remove the heatsink of your gpu and clean it from the shitty thermal compount the manufacturer putted it on (dont worry about warranty the same you are gonna void it in next steps)
then grab a stick comfortable enough and a HUGE METAL PIERCER SCREW
screw the stick in the middle of the gpu core
Congrats you got a gpu miner pick axe.
Profit
Enjoy
