So I have a 17" macbook pro it works right now but gets hot. The 15" also suffers the gpu issue. Now I been reading a few things online and well might be be extreme but if it saves the laptop then it worth it. Read in few places that they have got the 15" models down to 30/40 degrees. buy doing this: Drilling few holes where the fans are to allow more air flow. Most windows laptops have bottom vents to allow air flow. might seem extreme but if it keeps the laptop from killing the GPU then it worth it.
