Mac Pro Smell

I haven't found any recent postings about this so here goes. Does anyone notice a musty smell with the new Mac Pros? I recently purchased the new 8-core and it emits a very musty odor when powered up. My entire room soon smells bad and I have had to resort to a few air fresheners just to be able to work on it. I thought it might have something to do with it coming from China but we also purchased a 2.66 GHZ MAc Pro, that was assembled in CA, at work and it smells the same. I removed the side cover while it was running and the smell is most noticable in the front fan area. Any thoughts on what this might be and how/if it could be fixed. I am hoping it will eventually go away, but I've had the 8-core for over a month and it hasn't so far

I went through the same thing when I got my 8-core about a month ago. I called AppleCare and they were very concerned at first. They wanted me to take the unit to an Apple Store, but since the nearest one is over an hour away, I started the DOA process. On the recommendation of a second level tech, I took it to a nearby Authorized Service Center to be checked out before they declared it DOA. They guy in the service center said that every Mac Pro he has set up has the smell at first, so it appears to be normal in his experience. He thinks it is caused by a protective resin coating on the RAM PCB's and/or RAM riser card PCB's and should diminish over time as it burns away. It's been about 3 1/2 weeks now and the smell has almost totally gone, though I still get a whiff every now and then.

You may want to give AppleCare a call if the smell doesn't diminish very shortly.

I poked my head in my Mac Pro today after getting tired of the smell, and discovered the CPU heatsinks are speckled with partially-melted plastic shavings which are presumably the source of the odor. Looks quite reminiscent of a car's grille after a road trip.

The power supply also smells, but I can't see in there so no idea if it's in the same condition. I'm calling AppleCare tomorrow and will hopefully have a tech out Thursday to do... something.

The power supply unit is probably the culprit. I have the same problem. I'm working with a good tech at AppleCare to try and correct it. Let me know if want his number.

From another forum: http://forums.macrumors.com/showthread.php?t=297878&page=2

"Update: The repair shop just rang me and said that the smell comes from a chip with heatsink on the logic board and that this chip seems to be overheating. They have ordered a new logic board.

This is interesting insofar as all smelly macs that I have read about had the power supply unit replaced."

No my new 8core doesn't stink, but I have an iBook older G3 that doees smell like armpits and yes stinks up the whole room. Sadly it didn't stink until I sent it back to apple for repair, this was a recall repair and after 2 years of trying to convince apple of the problem,(until they did the recall). I had already bought a new powerbook. Now we just call it old stinky and use it in emergencys. If it was a new mac I would get on the phone with apple and tell them all about it, feel free to have them contact me, I would love to get a new ibook for mmy trouble.
Thanks,

Well I bought a new Mac Pro Quad 3,0 a few weeks ago. After some hours it started to smell very badly. You couldn't stay in the same room. Smelled like a sort of ammonia. I thought that it might help to run the machine under heavy load, to "burn out the problem." So I ran the machine 24 hours for 4 days in a separate room. It didn't change anything. So I called the company I bought it from. They replaced the PSU. Now after one week I ran into the same problem.

Wonder what to do now? Has anyone solved the problem?

Cheers

Thanks for the offer, Ken. The AppleCare techs I talked to (I was escalated) ultimately told me to try the Apple Store I bought it from since I was still in the return window.

The Genius there verified I wasn't crazy regarding the smell from the CPU and the plastic shavings on the heatsinks, and they ended up exchanging the whole system for me. One of the heatsinks actually looked to me like something impacted and then was dragged along it. Not good. From the way he described it, they would probably have been swapping out the entire logic board and both heatsinks anyway, so the new system was easier given the timing.

My original system was manufactured in China; the new system was manufactured in the US. The new one just plain smells like fresh electronics, nothing like the funky odor coming out of the first one.

All's well here now, and I still can't believe how quiet these machines are.
