I had the same problem with a HP laptop a few years ago. HP denied their was a problem. Long story short; I will never give that company any more money. As to reballing a graphics chip, I would buy a kit off ebay, if made, and do it right. You are still taking a chance because you most likely don't have a proper heating station? I really like the additional holes. I would like to know exactly where my fans are and make a proper template. I would then use a very small gauge drill, and put in hundreds of holes. I would try to make it look like it came from Apple that way? I use "I would" too much. I probally won't likely do anything until mine goes dark? (I think the correct way of drilling holes is dismantling the MacBook Pro, which has always scared me.)
