Hi folks,

Since Apple, -after hefty legal pressure, admits that their MBP's are poorly designed from an cooling / engineering point of view, I wanted to share my cooling mod to mitigate this problem. Its not perfect, but it works and lowers working temperature for the chips significantly.

For all 2011 machine owners, the cost free logic board replacement program of faulty AMD GPU's started a couple weeks ago.

It looks neat from the exterior!

Wow! This is the best execution of the cooling mod that I've seen yet. Really tempting to buy another bottom plate to try this. How difficult was drilling the plate? Was it easy to stay in place and get a really precise hole?

my drilling experience..

Two things I would do different after this first experience:

1. The square for penciling in the marks for the holes was a bad idea. You should use a circle to mark it, - not a square. With a square you end up having narrower spaces between the holes in the corners, and wider spaces between corners.

2. A spiral design might be cooler and easier to do.

What worked out well:

Most important to use a bigger drill for removing the chips after drilling. The material was easy to drill and rather soft. There might be no need for piercing it before drilling as I did. That saves time, depending what drill you use.
A 0,5mm drill worked out well. I thought I might break one, but I did not.

The temperatur at heavy workload dropped at least 20°. That is a lot and it really does make a difference. With a good sticker, you can improve the result from a "so so DIY job" to "almost super".

It will still die prematurely though.

If you can, I recommend reflowing the gpu somewhere.
