Macbook (Pro) Heat waay overated...!??

Damn those inch thick design flaws, too bad dell doesnt put out anything other then their plastic bohemith perfect designs.

what the heck. the mods lock one thread so you move on to here.

A desing flaw is a design flaw. And this design flaw had a simple solution in correct application of the thermo paste. Report after report of people here on this board is conferming that.

As for moving the heat better it is possible to "pipe it" around so it the heat engery is spread out of a larger area of the surface of the laptop which means the highest tempture at any one point is lower. Total heat engergy is the same but the tempture at any one point is reduced. Also the draw back to metal is it will quickly heats up to unbarible temps for human skin (60C or 140F is kind of hot)
The simple fact is apple screwed up bit time on this one. And it sits in the thermo paste they are calling for which is to much.

You are starting to target my post when one thread gets locked. Also please note that "pipe-it" is in quotation marks as just a term to help think of how heat can be moved. right now it is very localized and they just need to spread out the head some. Or find a better way of sheading it.
 
Im sorry that it seems like I am targeting your posts, however I do think that the problem really is that the computer is aluminium and that was a choice that apple made from the beginning to go with, laptop's either are going to have to get thicker or new and better ways of cooling chips is going to need to come out of this, Computer Companies continue to put the fastest chips in all of their computers and if they plan on keeping this in laptops then they are going to need to come up with other ways of cooling the chip other then constantantly running a fan, or making the computers thicker.
 
i dont know if this adds anything, but i read somewhere that these kind of intel chips can go up to 100 degrees celsius without doing damage to the CPU. i'll try to find a link later, but for now im too tired.:eek:

i really think that its smart of apple to make the case alluminum. id rather the heat on the outside, then on the inside and causing DAMAGE to the internal components. also, if the casing wasent aluminum, then more fans/heating techniques would need to be used. anyways

Yes on the other hand it is bad for the people that dont like the heat in their lap.

hmm that works.

See out side of the design flaw in the thermopaste. The aluminum just adds to the problem a lot. I going to assume based on you major you understand some of the thermo properties of alumimun. But for others, aluminum heats up really quickly, Either it or copper are used as heat sinks for there propertiys in how quickly they absorb heat and can disapated it. Great for heat sinks but a problem comes up when you use it on a case and have it near a heat source pumping out a lot of heat (aka CPU). it going to heat up really quickly and faster than it can spread the heat out among the rest of the parts of the case.
From there you form a hot spot. that one spot is going to be really hot and from thermo expasion that going to put a lot of extra stress on the case and risk causing warping in the long run. Plastic for example same eat engery is absorb but since it takes longer to heat up and does not absorbe it as quickly it has time to spread it out amoung the rest of the case so no huge hot spot going to form.

See this is where I a faulting apple bettween there huge design flaw in thermo paste they also are not disapating or at least spreading out the heat over the case. It going to lead to som huge issue later on. As CPU get faster and faster they are going to product more and more heat. If the Duo core are bad not they are going to be in real trouble in a few years.
 
Waaaaaaayyyy overrated my arse. If you plan on actually sitting this thing in your lap, then you are in for a big suprise. I have no problems with the heat, because I never actually sit it in my lap. But for someone does, I can see why they would be pissed.
 
The heat issue is a valid complaint for many people. I'm currently on a borrowed Toshiba 17" (1.83 Core Duo, I believe, separate GPU) that shows no signs of heating up whatsoever. It ain't pretty and super-thin, though - we OS X fans just have to deal with Apple ignoring the concept of 'form follows function.'

My returned MBP ran cool (40-43C idle), which was great. If only it didn't have the whine.

Sorry... but that's been said far too many times and really isn't an excuse. You don't drop a "standard" feature from a laptop (excuse me, "notebook") and then say "oh, yeah, don't do that."

And saying to buy an iLap is NOT a good suggestion. I already paid $2k for the laptop, why should I have to drop another $100 on something else to add functionality found in a $400 computer, especially when the fix is for Apple to just manufacture the thing properly.

I still don't see the problem...I watched movies for 4 hours straight, in bed, on the weekend, and the unit was sitting on my chest. When I was done, the bottom was warm, but it wasn't hot. If that's too hot for a lap, then maybe the problem isn't the unit, but the user.

I have a 5/25 - 5/28 manufactured 15" MacBook Pro and this is my experience too. I was very worried about heat issues when I bought it so the day it arrived I flogged both CPU cores at work for around 7 hours when I was done the machine was what I would consider warm it was still perfectly safe to pick it up. Oh and my machine doesn't whine either, actually it is the quietest notebook I've ever owned. I'm sorry to the guys that have the heat / noise problems but imho Apple have addressed them.
 
I agree, the warming it's not bad. It's actually good for me because sometimes my basement gets cold and I need to warm up a little :D

It's wayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy overrated!

Sometimes it irks me to even read it. I don't remember anywhere near this many complaints about the 12" PB, which, in my experiences was much worse! This MBP is a relief to me!

Now if only it wasn't peeling...

All you "it's too hot" people are CRAZY. Back in like, 1996 manufacturers were telling people to put a pad, don't remember if there was a specific term, between the notebook computer and their lap. Hence BEFORE 2000 the "laptop" was replaced by the "notebook" in just about every sense.

Only really old ;) users call it a "laptop" anymore.

/ Also sick of people who compare $500 comps to $2500 comps... OBVIOUSLY the $2500 macbook"PRO" is going to be hotter than any "consumer" portable.

// If you complain about $100 after spending $2000, you didn't have the money for it in the first place.

/// Trying to be nice, but thermal paste? What kind of kindergarden is this?

//// Not picking on vv-tim, just grabbed you to quote :)

umm the thermo paste is not kindergarden. Apple using way to much and it causing issues with getting heat to go from the CPU to the heasink causing it to get harder.

If you read about building computers you will see that one things they tell you over and over again is DONT USE TO MUCH THERMO PASTE. it will cause you computer to run hotter and put out more heat.

But we could compare it to other manufactor at the same level that dont have the heat issue. They clearly know how to do it.

For the thermo paste why is it when people are redoing it that there is such a huge temp drop. To much paste can prevent the heat sink from setting right interfer with tranfering of the heat. and so on.

2 degrees C huge!
 
Sitting this on your chest..yeah right. This is the temp of the CoreDuos, but you can ballpark how hot the case is.

75 degrees Celsius = 167 degrees Fahrenheit

CoreDuo reports 50C when I'm playing Divx formatted movies in Quicktime or VLC. Even normal web surfing shouldn't push the machine that hard. The only time I see 70+ is if I purposely push both processors to 100%...in that case, then the fans come on and it hovers mid 70s.
 
I don't think so...

So, I put my fingers on the bar above the F-Key's yesterday. I was playing graphics intensive games, so running the CPU & GPU hard. I had first degree burns after around 5 seconds.

Apple's response? MacBook Pros do run a warmer, this is normal. It's normal to have the casing that is right next to the keyboard so hot it will literally burn you?

I will wait and see how things go w/ the Merom chips, after the Santa Rosa chipset is out. Probably August 2007. If they are still having these ridiculous heat issues, I'm done w/ Apple. I would have been quite satisfied if they had made the laptop 1/4 inch thicker if that would reduce the heat issues. I'm very concerned about a heat induced failure, especially when I'm traveling, leaving me screwed.

Heck, if nothing else, give me a SW option to manually crank up the fans to run at full blast when I think the laptop is getting to hot.

That's still pretty hot.
50 degree Celsius = 122 degrees Fahrenheit

Thankfully I don't use my MBP for business use. I'm also afraid of a heat related compent failure. I'm sure that eveyone that has a MBP has, or will get AppleCare.

You might as well leave now then...sure, they will be more efficient, but consumers will demand an increase in performance...so processors will be hotter, not cooler. People talk about how Merom will save everything, but it won't. At the same clock speed, and same heat output, it'll perform 20% better....in theory, they could clock it 20% slower, releasing less heat and have the same performance...but why would they do that when they can push faster processors and make you want to upgrade. So the heat will be as "bad" or worse, because clock rates will climb....

Remember the days when people were outraged about having to put a heatsink on a CPU? Yeah....there's no turning back. Get used to it.

Just because you get a 50C temperature doesn't mean the rest of us do. Before the reapplication, I'd get 65C -- IDLE -- temperature. During load it would increase to 85C where it would get VERY hot on my lap.

Now, as I've said a million times before now, there was a dramatic decrease in temperature! I'm now at 46C as of typing this (with AIM/Thunderbird/Firefox). That's almost a 20 degree celcius drop, and my computer is now superbly comfortable on my lap, even while playing World of Warcraft (though it does warm up a bit).

Again, someone else above said that Apple fixed the problem... that's NOT TRUE. Keep reading around. There are a few that don't have problems, GREAT. Just because yours works perfectly doesn't mean noone else has problems. Keep it to yourself, thanks.
