Well, lucky for me, I've actually experienced LESS heat with my new white MacBook vs. the previous two black ones.

Overall "bloggy" review, with most recent updates.

But the upgrades in both 100gb 7200 serialATA from NewEgg and 1GB of ram vs. 512 have proved to be a non-factor in heat. I don't really know how to explain the difference between the 2.0ghz models and the 1.83ghz models, but spend LESS and get MORE for your buck. Just because the black model seems "cooler" doesn't mean its better. I had more problems with these than the cheap-o white one I own now. I'm extremely happy.

I've been using iState to monitor the temp. of my computer and it never pe'ks over 55C. That's a HUGE difference than the 70-75 I suspect was avg. of my old black MacBook.

Go white.

The only reason the MacBook "on average" kicks out about the same amount if heat is because 75% of the MB temperature readings in this test were fairly close to the Dell's, "averaging down" the two extremely hot MacBook temperatures (the top/bottom left corners).

Unfortunately for MacBook owners, statistical averages don't make the MB feel any less hot.

Thorn - people aren't saying that the MacBook runs cool, but that it runs the same temperature as similar PC's.

I thought iStat did not support temperature readings for intel macs?? What is the name of the program that does though ? I think you got it wrong maybe....

Whilst my Mac runs hot I have found a solution, and that is to use a Lapinator avialable from www.pocketpc-solutions.co.uk, which makes using my Mac whilst sat in front of the TV a pleasant experience.

Fellipe, they do. You have to get Rosetta to work with the espgs DMG. I installed THAT which works with PPC explicitiy, just incase it might work with Intel through Rosetta, and I was right ..... after that, I installed iStat which calls espgs to get it's readings to the GUI ... and worked perfectly.

Had two of the dell D600 series and they seem to run hot.

If you have the SpeedIt kernel extension installed (which CoreDuoTemp installs for you), iStat Pro and nano can read Intel temps. (At least on the MacBook Pro and MacBooks that I've used...)

Just another follow-up. You need two things, I believe. If you download and try and install the DashBoard Widget found here :http://www.apple.com/downloads/dashboard/status/istatnano.html ...

It'll tell you which two packages you need, one of which was the espgs installer .. which requires a terminal command line install, I believe .. and another iheader? ... but it'll tell you when you TRY to install.

Maybe those little "Intel Inside" and "Windows Genuine Advantage" (or whatever they have now) stickers are a secret source of insulation?

While it is hotter than my G4 iBook, I haven't had any problems with my black 2 GHz MacBook. I don't think average temperature means much here, at least for "laptop" use. That's like saying the temperature on the moon "averages" out to be comfortable.That hot spot is the problem. But I never use it on my lap anyway.

@ #2,
How is it just a statistical trick as you imply when every reading on the underside of the Apple is lower than the corresponding one on the Dell..??

My bad... I was only looking at the TUAW picture

? I don't see how we even get to "at first appears much hotter".

I see that the MacBook is 2 degrees warmer in the top left corner, an insignificant half a degree and .2 degrees warmer in the top right and bottom left corners respectively, and cooler everywhere else, by margins that more than offset the warmer areas.

When I first looked at the graphic I thought "huh, the MacBook is cooler than the Dell, except for slightly in the upper left corner."

Reply

Umm. ok. So they're both too hot.

Reply

Of course the only ones you hear about having "problems" are the Mac's

I've got one foot in boiling water, and the other in an ice bath. On average I'm feeling fine.

So does the white 1.83 Macbook run cooler than the 2.0? Is it that noticeable? (I imagine that the difference in processor speed is not noticable between 1.83 and 2.0, whereas heat issues might be?)

Also, are there instances where some people have Macbooks which run warmer than others? Or is it just that all Macbooks run hot and it bothers some people more than others?

I am hoping to get one soon (saving $$) and want to get all the facts before I decide.

But it's not a problem of the surface temperature, I think. it's the problem of cpu temperature... it's about 65 C while just using safari. while trying to watch youtube video it rises very quickly to over 80 degrees!!!
such temperature can cause a demage!!!
