Damn, too bad it's not your milk moo'in, could have won some sweet stuff.
(in all seriousness, until you figure out what's wrong, keep an off drive backup of ANYTHING and EVERYTHING important that you otherwise don't want to lose.) You might want to give AppleCare a call. no sig, how's that for being a rebel! |

Too bad it's not a 'Moof'... That would be really awesome, rather than annoying.

everything is running great. (it gets pretty hot) but its just a periodic little "moo" like sound. i guess nobody else is having the same experience. i was thinking its because of the 7200 rpm drive.

the ony reason it might bother me is if it got picked up in a microphone i was recording with. thats not acceptable.

Since it does get picked up by the microphone, post a recording of it here so we can better determine if this is something normal or so that those of us who have never experienced a "hard drive moo" can know how it sounds.

Okay, so i recorded the "moo" sound, and put it up on my .mac page. its kinda noisy, but you'll definately hear it.
http://web.mac.com/thedavidfalling Let me know if anyone else is having this problem. I am going to call applecare tomorrow and see whats up with it. I think its something worth having fixed. |

Almost sounds like a fan whose blades are hitting a wire.

Have you told apple?
It actually does sound like a fan hitting something periodically... |

I think it's hitting the enclosure.
Perhaps the fan flexes when it spins up and that is enough to foul any clearance in it's enclosure.. It's gonna make a mess inside your Mac as it wears the fan down, and may damage the motor eventually. Then again, it may go away by itself, once it's worn the tips of the fan off!

As I said, my MBP had the moo too. It makes sense that it's a fan hitting something. For me, it is most definitely the right side fan. If I put my ear up to the bottom right hand side of the keyboard I can hear it perfectly (haven't been able to get a good recording though). But now I also realized, only the left fan ever turns on...never the right side. I'm having a feeling this is because it is trying to spin up, but because it is being restricted, it spins down as a safety measure to protect the motor. There has to me some sort of resistance limit set on the fan motor right.
I really never though anything of the moo...but now I'm a bit more concerned. Edit: After reading some more posts and studying this picture (http://eshop.macsales.com/Reviews/ha.../Image14.html), it seems there are two possibilities. 1.) The fan is hitting a wire (it doesn't look like it could be hitting the case) 2.) Because the right fan is located so closely to the thermostat, it is possible it is cooling it quickly...really quickly, causing the fan to only spin up for less than a second and the shutting down. This repeats until it is actually cooled down. If #2 is indeed the problem, I'm guessing a firmware update could fix this. Last edited by Ominx : 2006-04-11 at 10:03. |

So I think I may have fixed the moo. I don't recommend this to the faint of heart, or those with a brain , but I decided to pop off the top case and take a look at the right fan. Getting the case apart really sucked. The sides were cake, but the front by the trackpad was a real PITA. Patience and steady prying hands. Anyway, there really wasn't much to see, there weren't any obvious obstructions or anything like that, so I screwed it all back together.
What happened next...I booted up and low and behold, I heard the right fan for the first time. As I said in a previous post, I have never heard my right fan on...and now both left and right fans are spinning at what I believe is normal speeds. Typically, my left fan would spin furiously, while the right would just sit there and moo. So I'll wait and see how long it stays "fixed" and report back. I'm trying to really stress the machine out, and so far so good, both fans spinning nicely. |

Update:
Last night both fans were running fine and I did not experience the moo. However, this morning I had been running for well over an hour and the right fan nerver kicked on and then about 5 minutes ago...the moo. So I'm not really sure what is going on. It would definitely be a very weird coincidence if I opened the case and then all of a sudden the moo stopped and my right fan started working and yet the case had nothing to do with it in the first place. So my story probably sounds like a bunch of BS, but that's how it happened and for those with the moo, I just wanted to update. I might try to open the case again tonight. A question to the techs out there...how dangerous is it to power up with the top case open? I'm sure opening it up isn't the smartest idea to begin with, but I really want to peak at that right fan on boot. |

Sounds like the right fan is messed up. I'd take it to your local Apple store.

As you are talking about the MacBook you still have warrenty on it. You shouldn't have it open up (I know that you know) - but you shouldn't have it open up!!
I control my technically geek mind until there is no warrenty left to void until I take warrenty offending insights! :smokey: |

Anyone tried using the istatpro widget http://www.apple.com/downloads/dashb.../istatpro.html to see if the fans are trying to spin when you hear the moo? If one fan is significantly slower than the other, you can take it to the Apple store...

"Temps" and "Fans" are blank on my system. Has anyone else tried this widget on a MBP? Are you getting readings for either the temperature or fans?

Yeah, i have that widget on my MBP and temps and fans are blank for me too. Any ideas anyone? Im definately not opening my case up, i'll take in into the apple store, thats why i payed $239 for applecare! I've been too busy finishing up finals at school this week to take it in and/or call applecare. I'll let you guys know why apple says about this whole fiasco once i get a chance.
