    Hey,

    I looked all over the web, and I couldn't find a thread on this. Are these common problems on the mbp (the whine, moo, etc) more common on the 15" MBP, or the 17". I'd assume the 17" would be better at heat dissipation, but I dont know about the other noises. Any 15" or 17" mbp owners, let me know which size u have ad what problems (if any) you have. Thx

    I'm a 15 incher.
    whine when power adapter isn't plugged in (very quiet though, any sound/music will easily cover it)

    very, very hot the first day. now it spends most of its life at 30-38 degrees Celcius

    no other issues

    I have a 15" MacBook Pro and the only problem I have it the function key is a little tilted. I don't notice it though. That is the only thing that bugs me. I have no whine (no, I'm not using any work arounds or anything) and it doesn't overheat. It stays at 85 or 90. Sometimes when I'm doing a lot it goes up to 120 though. But thats it.

    I've had my MBP 15 for about 2 weeks now and it has been really good. No screen buzz or CPU whine as of now. As for the moo, I think that is more related to the fans in the MacBooks. I can't recall my fans kicking on yet, even with heat makers like Call of Duty 2 - perhaps I should be concerned? I dunno. Anyway, all computers make noise- just walk into your school's computer lab and tell me what you hear, Mac or no Mac.

    My MBP does get really warm with intensive apps, but what can one expect with a fast processor being sandwiched in such a slim space and then being shrouded in super conductive aluminum which BTW, works to jettison the heat through convection.

    I don't doubt that some people are experiencing some legitimate problems with these units, which is to be expected with any consumer product but much of the complaints seem to be pretty particular and deal with the ascethetics or ambiance of these machines, which will be the case with individuals who bought into a cult rather than into a laptop. Apple has made excellent and innovative products throughout the company's exsistence, and when things do go wrong, the customer and product service is in the top ranks.

    If you have been searching the web for people who are experiencing these problems, big and small, you have come to the right forum to get their impressions. Good luck in your search and I hope you find the right item to meet your needs.

    just to add about my whine: it's not always there. It comes and goes,

    My understanding is it is just the 15" with these issues. From what I understand, the 17" does not have these issues.

    But I could be wrong...

    Ambient temp: 22 deg C. 17" MBP. It's not a Moobook, but it does whine sometimes. To be fair to it the whining is there on many of my non-Mac laptops and some are far whinier, it's just that the fans on them partially drown out the whining while it does not on the MBP because the fan is so quiet.
    Running Handbrake, iTunes and Camino (95% usage, CPU @ 2.17Ghz, plugged in while powering external display only in lid-closed mode) while sitting on the iCurve it's 86 degrees C.
    Interestingly dumping a whole lot of cooling moving air on the underside of the MBP from the back doesn't seem to bring down core temps a dramatic degree, although it certainly helps. With the fan going for 5 minutes it's still averaging 75 deg C (and the outside is merely warm to the touch around the back of the underside of the MBP).
    10 mins later with the fan blasting the back of the MBP the temp is down to 70 deg C.
    Handbrake has just finished so I'm going to turn off the fan and see how fast it comes down to idle temp with just iTunes going.
    5 minutes after fan turn-off, CPU in 1.67Ghz mode and only iTunes going (still in lid-closed mode) it's 65 deg C. Hmmm...
    Update: This morning an hour after switching it on in ambient temp of 19 deg C the temp is 46 deg C.

    No moo, no heat problems (40-43C idle, per CoreDuoTemp, room temp is 70-74F-ish).

    The whine that developed today kills me. I'm fairly sensitive to high-pitched sounds anyway, and I don't work listening to music, so it's making my MBP almost unusable. I guess I could just run PhotoBooth every time, but that seems like a waste of $2000 if I have to work around issues on a new computer.

    17" has the heat problem too, that's what i read on the official apple forum.
    some people say that the 17" whines too, but it's not as loud as the 15"

    I have the latest MBP 15" 2.0 GHz revision and it has no issues at all. Sure I can hear the fan if I put my ear up to the case, but that isn't a whine or a moo, as for it being hot - NOPE it runs heaps cooler than my PowerBook G4!

    The detection of the whine probably is also down to the same thing as the 'mosquito tone' thread in the Community forum. Those who're insensitive to high-pitched noise most likely won't hear it.

    i have the 17" and got it on monday june the 5th. as of today, almost 2 weeks, no whine, no moo and temp idles around 48C running firefox and adium. When i run Logic it gets up to around 57C, and i can still sit with it in my lap... i love my machine, and its absolutely perfect. The 17" doesn't even seem that big anymore, kinda small when i compare it to my PB w/ 26" samsung hooked up to it... i love it, and the screen res is great too...
