Third party Mac Pro RAM brings in the noise?

We know bad RAM can lead to a number of problems: crashes, bizarre behavior, data corruption, but extra noise? Really? Well, according to a tech note from Apple, that’s the case on the Mac Pro.

The new RAM spec that Apple began using in its professional-level tower is called FB (Fully Buffered) DIMMs. They’re a pretty scary piece of equipment: with heat sinks attached to both sides they look more like PCI cards than RAM. And they’re hard to get a hold of. The only company besides Apple from which you can acquire FB DIMMs is Other World Computing—either way, it’s a pretty pricey upgrade.

But according to Apple, third party RAM could cause your computer to run louder. I’ll let them explain by way of this knowledge base article:

Apple FB DIMMs have an accurate, integral thermal sensor that aids in tracking thermal requirements and therefore optimizing acoustical performance. The fully buffered DIMMs give the best system performance and fan speeds have been optimized for the quietest system operation.

Or is this just Apple blowing hot air?
