Should I replace the heat sink?
I just had a second hand replacement logic board delivered. I was sorry to see so much dust on the underside. I also noticed that it already had the heat sink attached. Now that is fine by me, one less fiddly thing to do, but would it be wiser to take it off an repaste it?
Also whether I do or not, what is the best way to remove dust from a logic board?
Is this a good question?
