Some MacBook Vents Blocked, Causing Heat Issues? Thermal Paste? [Updated]

The mac web has taken note of an observant MacBook owner who found at least part of the reason why his MacBook was running so hot. Apparently, some MacBooks are shipping with the rear vent (between the base and the screen hinge) blocked by a piece of plastic. Removing the plastic allowed air to circulate correctly and lowered operating temperatures dramatically.

While some users report having found the plastic, others report not finding the plastic, so mileage may vary.

Meanwhile, due to the controversy surrounding the excess Thermal Paste, MacDevCenter disassembled their MacBook Pro to see if reducing the Thermal Paste would indeed cause a significant change in the running temperature. Contrary to other anecdotal reports, they found there was only a 2 degree difference in temperatures before and after the extensive disassembly.

Interesting ... when your MacBook is shipped, a piece of plastic is actually blocking a vent.

Be sure to check this out:
MacBook's Vent Blocked

Be sure to check out the photos. If you have a MacBook, you'll want to check if the plastic is blocking the vent. An interesting discovery.

Which should have started happening to these (just another) MacBook Temperature threads awhile ago.

Starting to feel like the old freeipod threads, just so many they are annoying now.


I think it is a good post. He is just trying to help others out.

I didn't have the plastic on mine, I just spent 5 minutes starting at that portion to find plastic, started to scrape at it, too.

Nothing.

Sigh....

when will these heat issues for the new Laptops subside? Everyone gets all excited about the new books, then they all get burned....

How bad is it this time? :rolleyes:

This probably doesnt apply to the Macbook Pro as well?

Maybe thats what the extra 900$ is for. For more thorough checking so that silly stupid errors like these dont happen any more.

I assume we will see a post in their support section soon about this issue.

Thats a shame.

I am going to check mine when I get home.

Has anyone here found this yet? Is it really easy to notice or do you really have to look around for the piece of plastic? How easy is it to remove?

If Apple keeps up with this, they will ruin their reputation.
