It's pretty clear you need to do a better job of choosing your words.
I cannot control your comprehension of the English language. I have a minor in English so I doubt it's my grammar that is causing the problem. But I will clarify further since you obviously still either don't get what I'm saying or choose not to believe it based on your comments about this fellow named
Swampus. By the way, my two degrees are in Electronic Engineering, by the way in case you were wondering.
The point is that there should not be "a lot of thermal paste" in the first place.
He
asserts there's a lot of thermal paste. I have never seen a lot of thermal paste when I had my Macs opened, but then unless you're removing the heat sink or fan over the CPU or it's dripping out the sides, how the hell would you know how much paste they used? It's between the heat sink and/or fan and the CPU itself and thus normally hidden from view. How many Macs has he looked at that he can verify there's too much "grease". The fact he calls it grease instead of paste caught my attention in the first place.
Further, Swampus up above already addressed the fact that heat transfer should not be taking place through the body of notebook, at least not to the degree that it causes anyone physical discomfort.
Here I find the words "should not" in a place of authority where I have to question how the hell does Swampus know what it should or should not do? Is he the designer? The entire reason we call mobile computers "Notebooks" now instead of "Laptops" is that they were burning people's laps and creating a bad connotation for something that is implied to work on your lap and thus the industry started calling them notebooks so they don't imply any longer that they're meant to use or safe to use on your lap.
The simple fact is that a computer pushed to its limits is going to generate heat. How much heat and how that heat is controlled is another matter. My Macbook Pro can get pretty darn warm if I don't turn up the fans when it's pushed (again the default Apple setting waits too long to turn up the fan for the sake of "quiet" operation), but my Mac Mini is cold as a cucumber unless maxed out on all four CPUs, but the internal temperature probe says otherwise. It gets
very very hot
very very quickly so I adjusted the fans to deal with it. In other words, how the computer "feels" is
zero indication of whether or not the CPU itself is too hot. My entire point is that dissipating the heat to the case as a heat sink may very well be a design feature to save your CPU from burning itself up, not to make it pleasant to use the computer on your lap.
Apple clearly favors quiet operation over cool operation so they are going to get very warm before the fans turn up to evacuate the heat. That does not indicate one way or another whether too much paste was used on the CPU. Has someone had a CPU fail or panic a lot? If so, they might inspect the seal and amount of thermal paste. In fact, I see quite a lot of exactly that sort of thing when overclocking on regular PCs. You'll find out very quickly if the CPU is getting too hot. Windows will start freezing for one thing. How much heat is coming out of the machine is no indication. In fact, when it's generating heat, you WANT the heat out of the machine, not staying inside frying things. If anything, a hot outside surface indicates a
fan problem not a thermal paste heat transfer problem which again is why I suggested using
Mac Fan Control to lower the temperature sensor setting where the fan speed is increased. This will keep the case from getting as hot, assuming the fans are operating correctly.
