Did my e2160 today... it wasn't too bad to do. I was more nervous than anything, but once I got into it, I was determined. In the end, the chip survived and is now topless.

I started off with a standard razor blade, like one used in box cutters or scrapers... but then realized it was too thick. So I broke out a triple blade razor (generic Target brand) and took the blades out. They are perfect for this job. I was able to slide it under one corner and just cut around. Quite simple once I got it under. I think I could do another chip in a matter of minutes now.

To confirm, my e2160 wasn't soldered to the IHS, they seemed to use the same thing ASUS uses on the NB. Some sort of Thermal Gum/Soft Epoxy.

As for temperature results... I haven't got that far yet, I am having issued with mounting the heatsink without the IHS, I have come up with a plan, just haven't finished yet. I will update once I have results.
