Just emailed NextByte Pymble, my closest service centre according to http://www.apple.com/support/contact/

Up until now I've been using the SpeedCtl software hack to suppress the whine. Hopefully I can be rid of this whine once and for all!

What if your 13" MacBook makes that noise. Do you call AppleCare too? Or is it only for that particular model?

Looks like at the moment Apple only admit that the 15" MacBook emits whe whine at this stage...

what's the noise sound like?

Mine makes a hi pitch buzzing noise...kinda like the noise you hear through pc speakers if you have a dodgy soundcard (emf crosstalk)...although I only hear it if the room is quiet...otherwise it's not too noticeable

barton: Thats pretty much it, kind of sounds like crosstalk, but its aparently is just a poorly chosen capacitor that is not up to the demands of the core duo. Don't take my work for it ;)


I find it really noticible when i'm at home in a quiet room, otherwise at work with about 8 PC's all in earshot I can't hear it.

Not sure if anyone has realised, but those people getting new logic boards in MacBook Pro&#39;s are also being issued new install media sets. I guess the logic boards have been revised enough to render the old install media useless (or not bootable after its installed on the systems with the new logic boards).

I should be picking up my wifes MacBook Pro anytime between now and end of business, since I been informed the repair is just being completed now and will be available for pickup shortly.

The machine did have some CPU whine, although the major fault was the system freezing when it had more then 512mb of memory installed, as well as other issues (namely graphic bleeding issues when under load etc).

Let us know how you got on. At least in terms of my comment, the bad rep is with the sales guys. Would be interested in the how you go with tech/support.

Well, haven&#39;t heard from them yet, but they reckoned 1-3 days&#39; turnaround and it&#39;s only been 2 days, so I&#39;ll expect to hear from them Monday at the latest. Will let you know when I do :)

I wonder if I&#39;ll get a 2.0ghz logic board back... The processors are permanently soldered to the logic board, and the 1.83 has been long discontinued, so I reckon it&#39;s not totally out of the question :)

Be interesting to see, and that could be possible.

Got my machine back today, whine-free ;-) Seems to be running cooler than when it was new too, but I don&#39;t know whether that&#39;s because of an improved logic board or just a sensible application of thermal material.

i got mine replaced a few weeks before they admitted their problem. i was getting over 90 degrees under load, with the new board it doesn&#39;t go over 65.

24 hours after getting my macbook pro back from getting a new battery and logic board. It died. took it to my repairer earlier today who said it was probably a dud logic board. hopefuly the 3rd logic board will work properly.

Don&#39;t you qualify for a complete system replacement by now? i&#39;d be looking to get a new unit&#33;

Can I just take it to any certified apple repairer?
I need to get my speakers fixed too. Ze Frank was buzzing last night, it bugs me now. GRRRRR......

I may as well wait until the Merom MBPs come out before I put mine in for repair. Hopefully, if I present them with a laundry list of complaints, they&#39;ll give me a new one instead...

Let&#39;s see now... Whine, battery, peeling paint below the down arrow, sticky &#39;n&#39; key, insane heat, crackling from speakers/audio output jack... EDIT - and the Firewire port doesn&#39;t work until I put the computer to sleep and wake it.

i am running at 60*C after being up for half an hour but i think last night it was hot cause i was charging, running pro tools, importing photos, and on appletalk at the same time. it now seems to be pretty much staying at around 60*C. its alot cooler than before.. its all good :thumbup:

New thermal paste is known to have a kind of "breaking in" period, i think with artic silver 5 i think it&#39;s 20hrs (or something of the like), i know when i changed the thermal paste on my mac book pro the temp at 100% load went from about 68C to 64C over the course of a week of use. (mind you thats down from 85C before i replaced the thermal paste)
