    Hi, I was wondering if there are any tips or walkthroughs for doing this. I want to put some new paste on both the cpu and video card. Anything I should know before I attempt? Any tricks or things I should watch out for.

    You know what, the service manual goes over removing the processor, but does not go over removing the video card, so any tips or guides for removing the video card would be great, thanks.

    I can only speak for the w860cu but things should be the same. It's quite easy to remove the heatsink. CPU and GPU goes all the same.
    In each case unscrew the fan and move him away. You'll notice then that there are the numbers 1-4 engraved in the heatsink. To remove the heatsink you should unscrew it in reverse (4-3-2-1) (just verified that in the manual).
    After you have removed the screws completely (otherwise you could get stuck) you can carefully lift the heatsink off. I used to grab at the heat warning label and the grill. Try not to lean the heatsink to prevent putting pressure on the die.
    Afterwards clean everything with something non-fuzzing and a little bit of eg. isopropyl alcohol. Then add a whiff of thermal paste and put everything back together but therefore you should find many tutorials elsewhere. ;)

    I recommend you to verify this for the w870cu and wait or search for some other instructions in order to risk noting. :D

    You should do something to avoid static discharge. This is something many people don't bother with, ignore out right or think is unnecessary but why risk it with our expensive equipment. You should also look at the video of the W860cu disassemble to give you an idea since they are very similar. I posted this link before but don't remember where now.

    Definitely! I forgot to mention it. Once I destroyed a mainboard with such an overcharge.
