New macbook pro's still hot?

[pragmatous]

my macbook pro classic doesn't run hot only when playing a game. That's the GPU kicking in so it's the GPU that is getting hot. Blame the GPU makers because if you look at what GPU is in your mac and compare it to other laptops with the same GPU you'll see that they run just as hot if not hotter.
Apple has no control in what other vendors do with their hardware.

I don't think you know the whole picture of how computers work.

In my experience as an engineer, someone who builds infrastructures, I would argue that there is no amount of cooling system in a tight dense space that will be sufficient. Unless you use liquid nitrogen.

I think if you went with a mac that doesn't have a discreet graphics card you would be happier because it won't be as hot.

I've never had a laptop run as hot as my PowerBook or unibody MBP. It's not the effect of the aluminum either because the internal temps are higher. I don't think Apple's cooling system is very efficient.

The problem with that is that when you then run a GPU intensive task the CPU has to run extra hard and the extra heat is just produced by the CPU.

I think if you look at the graphs in the mach/github thread you will see that in some instances the CPU runs hotter than the CPU/GPU combination.

If a consumer is dim enough to not remove a hot object from oneself, they deserve to have their gonads rendered inoperable by said hot object to prevent the passing of said user's genetic material.

I am worried about my laptop's internals not about my gonads. As I mentioned I do not use my laptop for DVD ripping because it keeps my macbook at 89C for an hour and a half. I tried it once or twice and that is it. I also avoid playing any kind of game that is 2005 and later. I am assuming if I did, my laptop would have been dead a long time ago.

1) I am using iStat Pro and its telling me its the CPU's heat. I don't see a GPU heat.

2) I thought all newer macbook (except for the higher end 1) use intel Iris Graphics which is not a separated GPU. So where is the heat coming from?

I have a macbook unibody from 2008 and it gets super hot when playing videogames or running ripping DVD's.

I just want to know if the newer macbooks (rMBP) with the SSD are cooler now?

Is it still very CPU heavy to rip DVDs? Run Parallels?

When I say Hot, my CPU once got up to 90C/194F . It usually is always around 72C/161F

My experience is that the retina Macbook Pro runs much cooler than the older generation MBP. This is true for regular light to medium duty. For heavy duty task, I have only used it for computation stuffs and the newer version still runs cooler but the difference is not as large as the normal daily stuff. I think part of this is the CPU and part of it is the better air flow in the retina models.

Honestly, it's not something I'd be too concerned with unless your particular model is known for graphics failures (caused by heat).

I've owned various different models from 13-15" and have stressed all of them on a daily basis for years, no problems. Ripping a DVD for 1-2 hrs will NOT hurt the machine. I use mine quite regularly for VM's, video encoding, 3d modeling, you name it, and the CPU is frequently hitting it's temp limit for hours at a time (~212F+).

One big thing to check however is the amount of dust that's blocking your fans and/or ventilation. That alone can be a huge determinant of internal temps. Also, on the older units, it doesn't hurt to reapply the thermal paste. I recently did this with my 07 MBP and mid-2010 and both had reasonable drops in temp (20F on average).

The machine was designed, tested, and built by people who are highly educated with thermodynamics. Much beyond anything you or I am. Best let them do what they went to school for and get paid to do as they know what they are doing.

It would be better if consumer laptops had processors that only went up to a maximum 60/70°C at 100% load seeing as how it shouldn’t be hot enough to burn your skin.

But that would be like having a car with a tiny engine that can only just do 60mph when at full power - the driving experience is going to be awful and slow generally.

In the same way, better to have a processor that can use more power, in general usage it will be in short bursts that don't give a heat problem anyway. If you are running an MBP processor that full on load for long periods then really the user needs to prioritise that over the form factor and buy a Mac Pro - or accept that laptops are a compromise and form factor + load = heat...

 

[pragmatous]

Ahh... Well either way all laptops run hot with high end hardware. I've used a laptop fan and it works pretty good.

The problem with that is that when you then run a GPU intensive task the CPU has to run extra hard and the extra heat is just produced by the CPU.

I think if you look at the graphs in the mach/github thread you will see that in some instances the CPU runs hotter than the CPU/GPU combination.

Yes, but , The flame that burns Twice as bright burns half as long. Isn't that right?

Do you use any kind of extra cooling?

 

[Intell]

Not always. Depending on the fuel source and type, a bright flame would burn longer. Just let the machine work the way it was designed to work. They're designed to work best at those temperatures rather than at room temperature or colder.

 

[GhettoMrBob]

I've never used any other sort of cooling. Currently mine is sitting in the high 190's F and has been for a few hours (couple VM's and various other stuff). If you're really that worried maybe just use some software like SMC Fan Control to up the fans to keep it a little cooler.

As others have said, I'd just let the machine do what it's designed to do. The newer retinas do have better ventilation so it's not something I'd worry about.

It's a computer with chips made of silicon. They are designed to run within a thermal threshold that is higher than room temperature.

It sounds like you're looking for a macbook air, not a pro. Those can run 2005 games fine and have a low watt processor that is incapable of putting out that much heat.

Just from a few hours of use with a new retina MacBook Pro, the retina models tend to run cooler than the old cMBP. This my not be the case when I start to push this system behind web browsing.
