I'm back home so I was able to get the Fractal installed and get some final numbers that I'm pretty happy with.
Current max temp on the T-Probe is 54c with the fan profile not kicking in until 42c and running linearly up to max RPM of 3500. Seems to be running somewhere around 2300 - 2500 RPM under max load which is noticeable if I'm trying to hear it, but not so loud that I'll notice it kicking in if I'm not paying attention.
That's not the whole story though.... Those numbers are from the T-Probe I affixed to the bottom of the controller, and while they track well with the SSD's internal sensor (presumably what the controller would use to trigger any kind of throttling), they're higher than the readings it gives out.
The max temps I'm seeing from the internal sensor have dropped from a high of 72c all the way down to a peak of 46c once the combination of heatsink and active cooling have been applied. I'm not claiming any quantifiable performance boost, but I'm a lot more comfortable with peak temps hovering between the 45 - 55c range on a system that does have the potential of automatic throttling due to temps.
I wasn't in the mood to make a big deal out of the hardware pics so you'll have to accept some quick and dirty pics of questionable quality...
In case you couldn't envision what I was talking about when I mentioned ordering some stand-offs from amazon, here's a quick pic of it... because of the placement of the fan, I needed something that would allow the fan to clear the top of the case's USB 3.0 header cable. The kit I ordered had several different lengths so I was able to use the one that gave me just enough clearance.
Quick closeup of the fractal fan on the chipset fan mount that shipped with the ASUS MB in my sig. I suspect it's included because they think folks will be concerned about the high(ish) PCH temps that appear to be normal for the board, but it's well suited for cooling an SSD as well. It's also light enough metal that it can be bent a bit in order to direct the airflow exactly where you want it.
Just a quick shot of how it fits in with the rest of the build. (And yeah... I've still got a couple of wires to tie off....

).
Anyways... as I said, not completely sure it's going to provide me with any performance boost, but having seen temps I wasn't comfortable with, and knowing that SSDs can be affected by throttling, I couldn't resist trying to throw some active cooling onto it.
