Mac Pro 2013: Operating temp

I just bought myself a new mac pro 6-core and really happy with it so far but I have a few questions regarding temperature. Firstly I notice if I'm really giving the duel GPU's one hell of a workout with renders or what not the thing is pumping heat out of the top in an almost volcanic type way (really handy actually since it's winter and freezing here and this big house does not have adequate heating at all.) That said.. is it safe to operate this mac while it's pumping out the heat like that for extended periods of time in a very cold indoor atmosphere. How cold is cold you may ask? Well I can see my own breath and the actual temperature in celcius in here at night ( I tend to work through the night ) is between 2 degrees and 7 degrees. Now I know the Mac Pro can be stored at much lower temperatures than that even but more curious about whether it's actual operating temperature at such a capacity as I use it in these conditions will damage the machine potentially in any way. Do I have anything to worry about here? Cheers,

IMO.... no worries. Render away all night long. If the MP6,1 were to get to its upper operating temperature it will automatically shutdown or start off lining some of the cores.

Is that 2 to 7ºC outside or inside where your MP6,1 is situated ?

It is of course the temperature where the MP is situated.

Well if that is the case, and the upper 7ºC is used, we can be sure the 10ºC is but a few degrees below the Apple's lower limit. However, The operating temp range given by Apple is really to cover liability/warranty issues and I would assume there's some slack with this. Thus I see no problem operating the MP6,1 under these conditions, plus once the MP6,1 is underway it's own heat will be more than enough to raise the local ambient temp to be within the Apple's limits. IMO, there's no issue here.
 
The only issue I would be concerned about would be condensation forming inside of the machine due to the rapid heating/cooling/heating process back and forth. Do you have any way to make your work area any warmer?
 
It is a very large room I am in but I have managed to get it heated with the heater I have to about 7 degrees C, at the absolute maximum on the coldest nights while operating. This is not every night mind you in the winter here.. most nights on average the operating temp in the room is between 10 degrees C - 12 degrees C. Sounds like it should be fine.

This is what I am thinking as well. But the problem is not when the computer start. I am pretty sure the computer can boot at temp much lower than 10C. However, when it shut down, the rapid cooling may cause condensation inside the nMP, which is not a good idea.

However, water droplet can only form if there is any water vapour in the air. If the air is dry enough. I think it's quite safe to use the nMP.

Since warm air can hold much more water vapour. I think place a heater next the the nMP to heat up the air a little bit is already good enough (to lower the local relative humidity). No need to heat up the whole room. And this should be done AFTER the nMP shut down.

Never would have occurred to me to do this after but makes perfect sense. Thanks so much I'll use this as my standard operating procedure. Huge help guys. You people here are always fantastic. :)
