One does get spoiled by high-powered hardware. On the other hand, my power consumption on this box is down 280 W (665-385W) with the GTX 570 out of action.

Yeah, high power consumption is a minus sometimes, but I just don't have $$$ at the moment

Is that a cigarette burn on your screen, or Burnt by the Sun?

Of course, being 70 miles away, we have the same Santa Ana condition here, too. I know how you feel. I ran off to the air-conditioned work. ;-)

I remember my days in L.A. with tempatures going at ~105F (~40C) late in the afternoon... I always felt like a almost-bursting-popcorn-kernel when it got that hot and I couldn't do much...and dreaming when I could go inside and ahhh...

But I do know many people love the heat.

I spent 79 minutes in a single session at 97C one afternoon last week.

I'd love some nice dry heat right now because I'm still feeling rough from a cold which refuses to go away. Might have another sauna later today.

OMG!

Poor CPU at 97C.. for 79 min??? its goonnna diiie!

...

Wait, Whaat did you say?

I did have water-cooling. Evaporative cooling, that is. Must have used almost a litre of water in that time.

That isn't possible!

I can assure you it is possible. Homo sapiens is remarkably good at surviving high temperatures as long as the external humidity is low enough and enough drinking water is available.

I remember reading a study by the USAF conducted in the 70's when they were concerned about the well-being of aircrew forced to abandon in the hotter parts of the middle east. They put a number of fit young men into a sauna heated to 125C (much hotter than most!) and found that they could live in there for hours as long as they were naked (so maximum area to sweat from); sitting on cork or similar (minimising heat conduction into the body); the ambient humidity was very low to maximise evaporation (about 10% as I remember) and they had an unlimited supply of cool drinking water. The latent heat of evaporation of water is very large and the human body is very good at pumping it through the skin, doubtless because we are a largely hairless mammal which evolved in the African savannah.

The volunteers weren't comfortable in those conditions and each drank several litres per hour but they survived without any short term or long term ill effects.

I would argue Homo sapiens are remarkably good at surviving high temperatures even with high humidity, so long as enough drinking water (and salt) is available.

Even if most of the sweat doesn't evaporate, if it drips off you it is carrying away heat.
