Apple Knowledge Base: Optimizing your Mac Pro for acoustical performance

Apple has posted a Knowledge Base article regarding the use of heatsinked FB-DIMMS in the Mac Pro, which essentially serves as strong endorsement for its own (significantly more expensive) RAM modules.

The document states:

"Apple's fully buffered (FB) DIMMs come with heat sinks that have been designed for the Mac Pro. These DIMMs have been tested with the system to offer the best integrated thermal solution. 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. [...] For the best Mac Pro system performance, Apple recommends using the Apple FB DIMMs."

If you've installed third-party DIMMs in your Mac Pro and noticed a distinct increase in noise (or not), please let us know.
