Changing thermal paste

[Muscle Master]

So I got some left over IC Diamond 7 and It would really make me feel better to change the paste.. I seen some pics and apple is no better than dell when it comes to applying thermal paste.. lol they just "slop" it on there

Anyway.. I'm ready to do this but the only thing that's stopping me is the warranty issue

Now it isn't my first time playing with hardware so braking something isn't and issue.. but from what I'm reading is that it's "seals" all throughout the laptop so if I removed anything.. I can kiss my warranty goodbye

Anyone wanna shed some light on this..

Honestly there is no reason to mess around with it. Unless you are getting really high temps, I wouldn't touch it for the possibility of screwing yourself with the warranty.

The temp difference between CPU and its heatsink will tell you the performance of your thermal paste. I doubt you have a problem, but

If you have a C2D, you will probably see ~5 C temp difference at idle and <25 C under full load (eg running a stress test like yes > /dev/null). If you have an i series the max figure might be as high as 35 C because of the higher TDP of the i.

If you see temperatures in this ballpark, changing your paste will not make more than 1-2 C difference at full load. I have yet to convincing evidence of a new Mac where changing the paste made a significant temperature difference. With 4-5 year old Macs, maybe.
