I have a ~2 month old 13" MacBook Pro (specs in sig). Several hours ago, I reapplied thermal paste to my old (pre-unibody) white MacBook and I am THRILLED with the results. I have a thread about it here: http://forums.macrumors.com/showthread.php?t=932922 . My white MB runs so cool, that I prefer using it, rather than my MBP. I would replace the stock thermal paste with Arctic Silver Ceramique, but I am concerned about my warranty possibly being voided. Another reason that I wouldn't do this to my MBP is that my controlling mom will not let me do this to my new computer. If I can get any evidence from any of you that this will not adversely affect my computer or my warranty, I may be able to convince her to allow me to reapply the thermal paste. Thank you in advance for your input.
