Floor is the big one. 

FYI you should do it once a month. You should do it before it even builds up to a visually perceptible level.

Mine are getting hit with air every week or two, simply because I centralized all machines to a machine room and plumbed in air to the ceiling above. Every time I’m in there there is a yellow-coiled air hose hanging next to the rack beckoning me to give the machines a blast. 

But honestly, since the machines were moved from the floor of my carpeted office to a rack in the machine room (hard floor), and the lowest rack is still a foot off the ground, the amount of dust accumulation dropped a good 75% anyway.

So methinks floor+carpet placement are big factors.

I'm curious about heat and dust.  Perhaps my space is dustier than most (I live under three enormous pecan trees that spew matter year round.), but I blast the dust out of my MacPros two or three times a year to allow the air flow to glide smoothly across the internal components.  My box sits on the floor, which may contribute to the build up.  But, I wonder, with all that stuff jammed into one little cylinder is going to fare with situations like mine, or worse, for people who live in really dusty environs like Oklahoma.

Here’s a review of http://www.engadget.com/2013/12/23/apple-mac-pro-review-2013/. It’s as quiet as advertised but runs warm. I suspect if really pushed (render farm) Apple may have to boost fan speeds a tad.

 

Benchmarks and testing are fairly thin – of note is they apparently got underwhelming GPU performance and theorized only FCPX was able to use the second GPU card.  The storage system is fast as expected. They claim the CPU is not upgradable but GPU’s are. However, tear downs reveal that is could be upgraded as it’s socketed. But I would bank on ease or workability of those upgrades until actual parts and testing reveals if they will work.

 

But still waiting for a much more thorough review (i.e. Anandtech or Tom’s Hardware) to unravel mystery of GPUs.

A film is – or should be – more like music than like fiction. It should be a progression of moods and feelings. The theme, what’s behind the emotion, the meaning, all that comes later.
