superb results

I just purchased Arctic Silver Ceramique at my local radio shack, and I can vouch for the original poster, the drops in temperatures were significant, 10-15 degrees. I used to idle at 56 degrees Celsius with nothing running, and now I'm idling at 40 with nothing running. Hell, I even saw it go down to 35 degrees Celsius. I have yet seen my CPU go over 61 degrees, even playing 720P Video on Youtube. It's now a fantastic machine. I can only imagine how many Macbook owners think they possibly need new machines; when in reality, they only need to ad a dab of Arctic Silver Ceramique to their CPU and GPU cores and it's better than new.

Also, who ever in Apple's factories applied the thermal paste should be retrained in it's application. It was a mess on the cores.

I own an early 2007 Macbook 2.16 GHZ Core 2 Duo with the GMA 950, and I installed 4 gigabytes of ram. Fantastic machine and it is now running better than new. Thank you original poster.
