Spadoinkles Level 1 Level 1 (10 points)
Hey everyone.
As Lyssa half-solved my problm of my Mac overheating,
it comes to see that it will still overheat when running heavy applications.
My question is now that my friend is overseas, should I get him to get me a laptop cooling pad (Since the ones in New Zealand suck and the range is overly pathetic)

How much difference would it make?

MacBook 2.0GhZ 2GB ram 80GB piece of crap HDD, iMac 24" 2.4GhZ 4GB 320GB, Mac OS X (10.4.11), Ancient Zen Touch =P

    Depending what overseas you're talking about, I have [this one|http://catalog.belkin.com/IWCatProductPage.process?Product_Id=370982] that goes on sale for $20us quite often. The usb fan helps cool things down and the white color compliments my WhiteBook. I use it when I'm in bed and on the sofa. For desk/office use, I use a [Griffin Elevator|http://www.griffintechnology.com/products/elevator] -GDF

    Uhm not sure wat urem eaning by that,
    I say overseas because the range in New Zealand that I've seen are pretty pathetic, he's in Hong Kong, quality's decent and theyre cheap and plentiful
  • GfulDedFan Level 4 Level 4 (3,315 points)
    I wasn't meaning anything other than the fact that the products that I was mentioning might not be available everywhere. These are ones that I'm familiar with in the states which could of been the overseas destination. Since he's in Hong Kong instead, they might have an entirely different set of offerings but I imagine that they would have similar products.
  • Spadoinkles Level 1 Level 1 (10 points)
    Yup.
    However cooling fans will work anything with anything, or so I heard. Besides they're dirt cheap, come with good (12 year) warranty and moneyback guarantee and after he comes back another friend's going there 2 weeks later (Shopping spree but he claims its for family =P)

    I'll second that nice belkin coolpad as a suggestion.

    Let's make sure it's not overheating and is just doing its job!
    Here's some more information to consider:

    ~I've noticed on my machine running 10.5.6 that the fan kicks in at a slightly lower CPU temp than it did before. Not sure if the same holds true for 10.4.11 as I only have that on my iBook.

    ~How warm does your machine actually run when idle? How about when running several low-key processes?

    ~The fan in a MacBook WILL run more frequently than the fan in a PowerPC-based computer like the iBook. The processors used in MacBooks run a bit hotter than the ones in previous computers; this means the fan will kick in sooner than you may expect.

    ~I can't say if an external cooling pad will make an extreme difference in temperatures. On my iBook, it's enough to keep the internal fan from kicking in but I've yet to try it with my MacBook. It certainly won't hurt to have one though.

    ~If you're doing anything processor intensive (editing video, running software like Photoshop, or many games that take up all/most of the screen), the fan WILL turn on and I don't believe the cooling pad will stop it. Like I've already said, it certainly won't hurt though.

    Hmm, this morning my macbook was idling at 42 degrees with only Mail on. Then with Firefox adium and msn it's up to around 50 degrees. I used SMC at 4000rpm to keep it under 55 degrees .
    The cooling pad is to stop excess heating - sometimes my mac goes over 80 degrees like it did last night. My friend said his overheating HP dropped to under 65degrees with the pad at 2800rpm.

    My fan is preetty much always going even when idle D:

    Are there any other processes eating up CPU in Activity Monitor? If not I'm stumped as to why your computer's so noisy. Perhaps Tiger is partly to blame--that's just a thought, I've no way to prove it.

    Nope. I know it's crazy. Previously it wasn't and it was definitely going better in Winter particularly when I brought it out on the deck over the cool (and dry :P)

    ANyway here's a little screenshot

    Shows my day-to-day hectic dock, Activity monitor and smcFan up the very top (near the airport status) Not sure how much it helps D:
  • Lyssa Level 6 Level 6 (17,585 points)
    Hmm. Those items in the dock aren't all running, are they? Just convenient shortcuts, yes?

    Maybe the fan in your machine is quite a bit different from the one in mine. That might explain the RPM issue. I wouldn't advise lowering the rpm speed too much without confirming how low it can safely go.

    Not sure if it tests a fan, but you might want to give the Apple Hardware Test a try. Pop the Install Disc 1 into the drive and reboot, holding down the D key while booting.

    Ive done that.
    Now its doing 65 degrees at 6200rpm with ust Firefox mail adium and msn on (like always)
  • Lyssa Level 6 Level 6 (17,585 points)
    What's the minimum speed that smcFanControl lets you choose? You may as well adjust the speeds and see which one gives you the best results.

    Also, for the thread you've got going about BootCamp, repost in the BootCamp forum. You should be able to get more answers there.

    ~Lyssa
  • Spadoinkles Level 1 Level 1 (10 points)
    Uhm.
    THe minimum is 1800rpm. However my mac's funny and if I don't limit the minimum speed the fan will go down to 1800rpm and my mac will heat up crazy.

    ANd since you were saying about Safari and Firefox that will free up CPU as needed, is there a way to limit how much of my CPU gets sent into it?
    Because one of my browser mails explodes up to 90% CPU =.=
  • Lyssa Level 6 Level 6 (17,585 points)
    Not sure if you can control that. A quick look through FireFox preferences doesn't show me anything. What mail site brings up that spike? I'll test it on my machine and see what results I get.

    gmx
    I use it because of its easy email-forwarding and POP3 / iMap which hotmail and yahoo don't provide for free
