I keep seeing people with - temps on there CPU

maybe......
i went off searching to see what parts make a fridge...woultn work in a computer, best off just buying a fridge and maybe drilling holes in it for water tubing, sealing up the holes etc

the space thing comes up every few months - wont work.

also, space has no temperatre, given that we regard temperature as a reading of the state of matter of the medium we are measuring - space has no medium and so to temperature.

if an object in space creates no energy/heat and is not affected by any other energy sources - unlikely - it will slowly cool down untill it matches the temperature of the microwave background radiation (about 3 kelvin iirc) due to radiation of heat, but it will take a while to reach those temps. if its got line of sight to a fairly close star (eg something in orbit of say the earth) unless its highly reflective of heat it will get extremely hot very very quickly. go sit by a window on a sunny day in an airconditioned room - you will still end up sweating - and the atmosphere has cut that solar energy reaching you down by a good factor or 2.

this is why things like the space shuttle are not powered by monster quad core storming cpu's but very frugal old chips (among other reasons) and why your not allowed to take up anything very power hungry. the thing spends all its time with its insulated and reflective white surfaces presented to the sun and dark radiative surfaces used as heat sinks and turned to deep space simply because its so hard to shed much heat.

Apollo 13 (usually used as the benchmark argument against the above here) got so cold because it spent a week, mostly in the shadow of the moon or earth, with a small profile to the sun, which was highly reflective. with a combined heat output of about 200w onboard, comprising the 3 guys and a handfull of lightbulbs it was steadily losing heat but still didnt instantly deep freeze.

Very interesting read, thanks :)

I can't help reading that and not seeing the hyphen/minus sign and thinking, well eveyone has a temp their CPU... lol.

:)

With reference to the temperature of space, I guess the nearest to 0°K would be between 2 black holes if that could exist. All heat/light would be drawn to to each of the black holes missing the void in between.

I am sure space has a temperature, apparently its like -260 something, my teacher was talking about it, apparently there is a propor 0 degrees which is the temperature of space and its like -260 of our degrees or something :confused:

Was close enough.

There is such a thing as absolute zero, but space is not "at" absolute zero. There is background radiation which accounts for the equivalent of a couple of degrees in real temperature terms.

you know I was joking right? the fridge thing can't work, period.

Happy to explain why, I was just having some fun because those threads always seem to pop up when it starts getting warmer.
 
Actually, when you think about it, minifridges are actually based on a largely abandoned CPU cooling technology, the peltier heat pump.
Mine's got 2 rather sad peltier's at the back and is, frankly cack.

(the polarity of the peltier's can be reversed so that the unit can be cack at keeping stuff warm as well).

If it can't shift the heat of a ham sarney and a tin of redbull, what chance a Q6600 at stupid.5GHz ;)

There is a reason TECs are largely abandoned apart from those dedicated few...
 
just for the record fridges are designed to keep cold things cold not cool down constant heat sources so they would burn out.

Just thought I'd stick it in here before anyone took it seriously :)
