MacBook - Heat concerns

Message #1 - Posted 2006/06/03 - Jay

I've had my MacBook for a week now and am getting a little concerned by the heat. I have it on an iCurve so can easily feel the underneath when it's in use and am surprised at how hot it gets. The area that gets particularly hot is the area under and around the left hand side of the keyboard. It's not too hot to touch, but still a *lot* hotter than I've ever been used to. Also, I don't seem to remember hearing much noticeable fan noise?

So: Are there any ways I can check if the fan is OK - any diagnostic tool I could download to help, that anyone knows of? And does anyone know of anything to enable me to monitor the temperature and how/whether this data could be checked against recommended MacBook limits.

I'm not using it for anything intensive- just general browsing, office stuff at the moment.

And what experience have the other MacBook owners had re the heat?

Any help/input appreciated.

It's all in how you think of it. Is it really a problem OR a FEATURE? If
If you are trying to heat your flat, it's a feature.

You are not allowed to know anything about your MacBook. You don't need to.
It works perfectly... end of story.

Yes, yes, I know. Naughty pictures.

And what experience have the other MacBook owners had re the heat?

Well, some brew pots of tea on theirs.

Any help/input appreciated.

No problem, that's why we're here.

Funnily enough, this article was updated only just yesterday...

And there's this with a picture of the potential problem...

Just a thought.

Mine gets too hot to use directly on my lap. On the bottom left side. The top gets warm but not too warm.

I can live with how hot it gets, whereas I took back a MBP as it got too hot.

I had a number of HP laptops and tablet pcs and they too got too hot to work on your lap directly - actually the last tablet I had gave me a cooked feeling that made me walk funny for about an hour - I stopped using it on my lap after that.

I haven't had a tabletPC that got too hot to work on my lap, or any laptop for that matter. I am a bit concerned about this. A laptop computer that I can't use on my lap is useless to me. I guess if it is like that I can send it back as not fit for purpose but it would be a shame

Mine doesn't feel anywhere near as hot as my powerbook 1.25ghz does *BUT* that could be the feeling of hot metal is worse than hot plastic ;-)

I reckon mine is completely within spec for the core duo cpu, better than the pb I've had for 2 years with no problems and about the same as some pc laptops I've had!

Well, I was always taught by my chemistry teacher with the asbestos fingers that 50C was jolly hot to touch and 60C was *too* hot to touch. I think he was exactly right.

If they have made the MacBooks very thin, the heat has to go somewhere. I don't believe that the Intel chips run particularly cool so basic physics says that the best hope is that the plastic case of the MacBooks will diffuse things slightly. But that's the limit.

Which is rather stupid. This tiBook is on my lap a lot and doesn't get that hot.

It doesn't get that hot, or maybe your goolies are abnormally cool and need
the extra heat. Not unusual for men your age.

Yes, it's the bottom left side (at the back), under the left hand side keys. And the warmth comes through to the top. I guess I'm just not used to *any* laptops getting so hot as I've only ever used a G4 iBook for any length of time & that hardly got hot at all.

I can live with how hot it gets, whereas I took back a MBP as it got too hot.

Can you define "too hot" as I'm still trying to gauge whether mine is getting 'too hot' or not.

Cheers

Jay

P.S f.a.o Gareth - Hardware Monitor says that it cannot detect any sensors on the MacBook as it only covers machines up to 26.4.06?

Uncomfortable to touch near the function keys and very warm palm rests and keyboard which made it annoying in use.

The MacBook gets hot on the bottom of the case but the palm rests and keyboard don't get so warm that its annoying in use.

Cheers Ian,

Another thing which is kinda concerning me - Should the fans be audible? I don't recall ever hearing any noticeable fan noise. I know very little about hardware, or if & when fans should kick in. And I can't check with Hardware Monitor as it says the MacBook is too new a model.

CoreDuoTemp will allow to to monitor the temperature that the CPU is reporting: <http://www.macupdate.com/info.php/id/21674>

<http://www.intelmactemp.com> is a user contributed database of temperatures, but I don't know how reliable it is.

Mine has never got hotter than 84C, caused by running two instances of 'openssl speed' in Terminal (to make the CPUs work hard). Generally it's around 70C which I do find uncomfortable.

As you should. 60C is the normal human limit for the 'too hot' sensation, so if the CPU is running at 70C and it rejects its heat via the casing, that'll be too hot for any kind of comfort. --

Just for comparison, my GP 1.25 tends to sit at the 57-58C area.

Haven't tried the PBoko - must get a round tuit.

Thanks for that Paul. It's good to have something to give an actual measurement, which can be compared to other users' figures. It's probably just me being overly concerned because I've never experienced laptops that actually get hot. (Although saying that, my experience with laptops is limited to my G4 iBook:-).
Plus the fact that it seems *very* quiet, which led me to think that the fans may not be working properly. Like I said, I know next to nothing about the actual nuts & bolts.

If you listen in a quiet room you can hear the fan spin up an stop a lot. this is the infamous moo sound.

Aaah, that's the moo-ing is it. It's hardly anything on mine (thank god):-)

Oh, and for anyone interested, a new version of CoreDuoTemp (0.9) has just hit version tracker:
