macbook question

imactheknife · Oct 6th, 2006, 06:23 PM

I finally got a game running on windows to work. The problem is does windows not use the fans to cool the core duo processor in the macbook? I mean the thing is cooking hot 122 degress F. I booted back into OSX and the fans stopped running but is still says 122 F? whilw I was in windows the fans were Going full throttle? thanks Mark

now it says 136 F and no fans! is this going to fry soon?

that is pretty hot. i can't answer your question but i'd shut it down for a while. one of my friends has a macbook and his started to run hot so he shut it down for a day and it has been fine ever since.

okay it's down to 122 F but the fans haven't kicked in and it doesn't feet really hot? anyways is bootcamp and XP going to be a problem for Mac laptops being hot? and frying? I was just trying to play a game! maybe the cdrom running made it hot? I took the cd out and heard the fans going full bore. oh well...if it fries back to Apple she goes....

Converting your Fahrenheit to Celsius, you're at around 50ºC. As far as Intel's specs for the Core Duo is concerned, you're fine.

According to what I have read, Core Duo CPUs are rated to 100C. YES, that's the temperature that water boils at! Go over that and data integrity suffers. At 125C they have a hard thermal shutdown feature to protect the CPU from actual damage. They throttle to keep temps under 100C to ensure data integrity. Throttling can also be used as a power saving strategy, but temps of less than 100C under load are within spec.

I have a 2GHz MBP, and I idle around 50ºC and get up to around 70ºC under heavy loads. Currently, I'm at 72º. My fan is not on and it hardly ever goes on unless I get a beachball.

Some links for ya:
Intel Mac Temperature user reports. Number of entries: 373. Most popular CPU frequency: 2GHz. Average temperature under load: mid 70's.

So, even though they are HOT as HELL for our little pinkies and bare thighs, it seems there's no need to worry until you're into the mid 80's. Hot for us carbon-based overlords to be sure, but not for our silicon-based slaves

For more fuel for the fire, however, you can check out the horror stories below:

This could be nothing but FUD, but the switch to Intel is a major change for Apple, and the original releases of such new hardware (traditionally called "Rev. A" systems) can have problems... and going to Intel is definitely the biggest change Apple's hardware has ever undergone:

I did some digging around at Intel's site and have confirmed that 100ºC is the maximum safe range, with 125ºC indeed invoking a hardware shutdown to prevent damage. If interested, consult these two geekspeak-riddled Intel documents:

Power and Thermal Management in the Intel® Core™ Duo Processor

PDF datasheet for Core Duo and Solo

Pardon the pun, but we're cool!

Macaholic, some great reading there, interesting links.

I'm typing on my black MacBook; actually, on my Apple bluetooth keyboard. The MacBook is perched on an iCurve on my desk. The MacBook, many will recall, was a warranty replacement for an iBook G4. The black'Book is week 38 revision, and experiences none of the problems, so far, that have been reported, mostly for white Macbooks, no heat, warp, moo, obviously no discoloration, I'm not even touching the thing. I upgraded the RAM and hard drive before using it.

I'm waiting for it to settle in, I've conditioned the battery, and while I've given it a couple of intensive tasks, nothing much really that would tax it.

The Mikemchargue blog noted that all new Apple computers are now "Rev. A." I wonder how long it's been since that has been the case. "Want a new Mac? Here's something that hasn't been out forever."

Nothing over 50ºC here. Loving the iCurve.

Glad you like 'em

The info therein certainly sets my mind at ease.

I have a 1.83 Ghz MBP. The hottest I have ever seen it is 47C under load and sitting flat on a desk.

I bought an aluminum cooling pad which elevates it to three different settings. The rubber pads on the aluminum raise the MBP about 1/4 inch off the pad. The pad itself has a USB powered cooling fan at its centre. Operating on the pad, I have never seen it above 41C.

I normally run Photoshop, iPhoto, Appleworks, Safari, iTunes and Mail at any given time when these temperatures occur.
