The temp on the Odroid-C2 running 4 concurrent jobs in an ambient air temp of 26C is around 82C. This is an OPEN Odroid sitting on a table top.
I directed a USB table top fan at the Odroid and them temp dropped immediately from 82C to 49C within a couple of minutes. 49C seems quite satisfactory. 82C is bothersome. Remember the Odroid-C2 comes with a large heat sink attached so 82 is high to my way of thinking. Checking the temp again it appears that with the fan I am able to hold 49C. Definitely a candidate for a tunnel or tower with fan.

modified the above like the following:
Fan is a 5V two-wire and plugs into the Odroid-C2's 5V/Gnd pins on the header.
That looks awesome! Can you share the source of your fans please?
You can find them on ebay and other sites. Things to look for: 5V, CFM (how much air it moves), and plug. The one that I used and the one pictured in the above link need to have the plug removed and replaced even though my picture shows I used the original plug. I noticed the original plug is not a perfect match for the header pins so I cut it off and used a different plug type. Note you will need pins and a crimper or buy ready-made cables from the same site and solder to the existing fan wires after cutting of the original connector.
Ordered an Anker 6 port 60w Powerport. If it doesn't work with the Pi3's then I can always use it to charge the phone :-)
It's arrived and has been put into service. I had one Pi3 turn off its power led for about a minute, but the activity led stayed flashing. After that it came on constantly. I presume that was it "learning" about the device.
The faulty Pi3 I have noticed has been blinking the power led once every couple of seconds so even it thinks it's got a problem. Putting it on the Anker didn't make any difference there.
So far so good. Might order another one for the other Pi's.
As we are already nearing the end of the current GW run, it doesn't make sense anymore to publish an ARM version for it. But we are already planning for the next GW search run, using basically the same search app. Stay tuned.

Just asking. How far off is the next GW search app?

The next GW run is under development now and we hope to start it in a matter of weeks. This run will use the current search app.
My question regards powering a Pi2/3 or Odroid through the header pins. It is my understanding that by doing so you bypass an over-voltage logic which is not present on the header pins. Would the use of a regulated power supply eliminate/limit this risk? Or can someone point me in the direction of a separate over voltage "board" for a Pi or Odroid.

Correct. You can see the hardware that the PI uses to get the internal 5V lane from the USB connector in the official schematics:

There are several solutions that power the PI thru the header pins and take care of voltage adjustments and protection themself, most of those also allow a battery to supply power if the primary power source fails, so it's like a UPS (e.g. if one wants to power a PI from a car's 12V power but make it shut down gracefully when you stop the car). Googling for "Raspberry Pi UPS" might turn up some interesting offers. Those solutions are meant to be used with a PI this way and I would trust them more than just any regulated power supply.
