That's obviously only your opinion, as notebooks are configured for a variety of intended uses. They are not all alike and not all configured to handle every possible task. That's why a MBP may be considered overkill for some users' needs, while it may be completely inadequate for others. It's up to each user to determine what their own usage requirements are, then shop intelligently for the computer that meets those needs. Buying the wrong computer for your needs and then blaming the manufacturer displays a lack of experience and unwillingness to accept responsibility for one's own inappropriate buying decisions.
Would you please just give it a rest? I have read several educational posts about heat sink manufacturing, thermal past, and simple ways to improve heatsinks, which is interesting and relevant, even if the heat issue is not a "problem". In my experience my macs always get hot and if that can be prevented, great.
In the middle of this discussion I have to read multiple posts about how this is normal, not a problem, macbook pros (PRO being the keyword here) are not designed to run under heavy loads repeatedly or for long periods of time,or how its not appropriate to encode a lot of video on a MBP. All of them make no sense, lack data, are wrong, or are annoying in their lack of addition to the discussion in various combinations. You did not even read the OP as it was "too long".
We all know that if we need to run processor intensive stuff for days to get a desktop (or a MacPro, since an imac is essentially a big laptop). However many people (yourself likely included) do use MBPs for intensive work multiple times a day and if improving the heatsink allows better cooling (thus a cooler laptop that runs better or can have better parts), then so much the better. The OP is completely logical and is discussing improved heat sink contact, not liquid cooling or anything unlikely in a laptop
I also find it especially annoying how you also say most MBPs are used for light work and web browsing, which not mean that MBPs should not be designed for professional, hard work. And alluding to your quote above, buying a Mac Book Pro for heavy use, even video encoding, is
not inappropriate. A MBP should have the best cooling.
In short, if this post was "TL;DR": I have been enjoying this thread apart from your repeated off topic interjections about how the heatsinks work great, when as far as I can tell, you have never seen a heatsink in a Mac. While your computer runs fine for you, it clearly does not for the many who do not enjoy their macs becoming hot to the touch and I would like to read more about it. Please give it a rest. Thanks.
