How cold has your Mac been?

^^^ yeah, that sounds low for an internal temp. But too high for an external one. 
If the OP meant externally, about 5ºC while running. And (accidentally) while in sleep it spent roughly three hours at -62ºC.
Internally my 2008 MBP sits around 90-120ºC given average use, with 55º being pretty normal for when it initially wakes up.

I would think so too, but like you said, there's no way a running CPU would only be at 16ºC.
SMC Fan Control was saying 16C on a freezing cold winter morning when I first started it up. Then the computer warmed a bit and sat at a healthy 50C.
iStat Pro is saying the same as SMC Fan Control for the CPU, so I guess the CPU was 16C. But remember, the machine had only been running for several seconds when it was 16C.
BTW we're doing Celsius

I will have to do you one better, sir. 15˚C. 'Twas a very cold afternoon (-26C), I had the window wide open to air things out a bit. Additionally, at the time, SMCFanControl was being an absolute dick and refusing to let the fans run back down to their idle speed, instead they were at max. So, my Mac Pro brilliantly had a 15˚C CPU temperature.
Beat that. My CPUs typically sit around 30-35˚C.

Moses! It's not good to keep your computer near your toilet cistern either ;D
26 C on most boots, which makes sense (room temperature D

If it is properly sealed with a good external cooling system to counter the sealing then its alright to keep it in your cistern.
Well, I don't imagine that's all that terrible, but booting it immediately afterwards will heat it up quickly, which is bad when it's that cold (which it has no reason to be anyhow.)
It is the hardest on hard drives and batteries. I have lost a few HD based iPods that way.
SMC reads between 35C and 45C for my 2006 Mac Pro. It changes depending on the temperature that day, as well as how hard the machine is working. It's usually around 25 or 26 C when I first wake it out of sleep or boot it up.
Hard drives have very tight tolerances different types of metal contract(and expand) at different rates and that can cause an increase in fiction during spin up/warm up. Any type of lubrication in the sealed bearing of the motor or read/write head arm will be more viscous causing higher resistants and load.
It isn't that big of a deal at/around 0ºC but the lower the temp the more problems you will see. Of course when you get to those temps you are way out of the recommend operating temperatures.
That is one reason I like SSD based ipods, then your problem is the lcd display not working.
