Computer makes room hot!

Since its summer now i've noticed my computer can really heat up my room. I usually leave it on all the time is there anything I can do? I am not overclocking and I have a 1ghz Athlon with a KT7. Any suggestions besides running my $$$Air Conditioner$$$.

Oh yes, the Bartons are MUCH better with heat

No I didn't say that....I'm a good boy...yes, I'm a good boy...uhh huh I am good..........
I tried the door jamb fans (located upper corner of jamb, hot air out) to get the heat out and a fan on the floor blowing in (cool air from floor) and it works abit, but not so much as you would notice after being in the room awhile.
Get the APC server room cooler or similar and you will be...cool again.

Router is not a bad idea I bought one becasue I was sick of the humming noise running 24/7 PC's about the house not to mention EMF flying everywhich way.

Lol.
Imagine this guys, Arizona summer heat + 21' CRT + 2x 17' CRT +226 watt Peltier + 2600+ running full load all day... My room can hit above 90*f, the air conditioner has no effect on the amount of heat being put out by all my stuff.
Sit in my leather chair with a coke and a 20 inch fan blowing on me. Only problem is when your eyes start to itch and turn red from drying out
CCW - any relation to CCx?
Nope, afraid not. Im the CCW from XS and AOA.
ROFLMAO... real s-m-r-t yeah?
My room has a peculiar temperature gradient. The area around my bed feels like 20 degrees celcius most of the time. Then as I move towards my computer (17" CRT, Altec Lansing Speakers, High wattage lighting system), it starts to feel like a Dodge Viper without its air-conditioning on.
Also P4 put out a lot more heat per rating than AMD CPU (They have grater surface area so they're easier to cool.
P4 2.40ghz v1.500 = 77w
P4 2.53ghz v1.525 = 80w
P4 2.60ghz v1.525 = 83w
P4 2.80ghz v1.525 = 85w
P4 3.06ghz v1.525 = 95w
For my comparison my Barton @ FSB400 2.30ghz v1.85 (PR3250) produces ~100w
Just a guess

>I have sensors installed, and can see the effect within 10-20 seconds of powering up/down such a fan....While the temp rises, I feel cooler.
>I never suspected this to happen, until I fitted sensors, it even picks me up when I come and sit at the desk.[PC build into desk]
I like your thinking on the principles at work here and how you choose to describe it. You wouldn't normally associate heat with jumping but the mental image it conjours up is great and got me thinking too. Well atleast trying to remember what I should know about all this sort of stuff.
I was taught that heat transfers by two methods convection & radiation.
Convection I guess is like you describe with heat offloading onto passing particles that come into contact with a hot surface. The fan on your heat sink moves them along and the quicker the better it seems. This I can understand. If the warm air particles hang around the heatsink too long then the temperature differential is lower and the heat doesn't want to jump ship quite so much and your CPU starts to overheat. Now warm air rises because it is less dense so the particles around your heat sink will move along without the fan but they drag there feet and generally wandering up and away too slowly. Stick a fan on to gee them up and everything is under control. Convection requires particles to work so in a vaccuum there isn't any convection which is how a thermos works.
Heat also transfers by radiation which I don't really undestand. Radiant heat is transmited by the hot object and absorbed by surrounding surfaces and can travel accross the vaccuum of space hence radiation from the sun. Now some surfaces will absorb radiant heat better than others. Surfaces that are matt black are good absorbers and surfaces that are white or mirrored are poor absorbers which all sounds alot like light to me. Now if a surface gets real hot it becomes white hot and produces light so does that mean that radiant heat is light but outside the visible spectrum? Anyway everyone should paint the inside of the PC cases matt black it will get those case temps down which is something I never thought of before.
Sooo.. what can I suggest to keep cool in a hot room having considered the methods of heat transfer. Well its obvious firstly you need to dodge the air particles in your room so that heat can't jump onto you and secondly you need to body paint yourself silver and sit in the dark. Turn the brightness right down on your monitor so you can barely see it but can still operate you're PC.
Do I know what heat is yet?
NO not really.
So painting the inside of the PC case black is good as it will absorb the heat. What colour do we need to paint the outside of the case to dissipate the heat?? And do these principles hold true in the dark??
Maybe I shoud take my pass and leg it.
You are asking me if in the abscence of light a white surface is black and the answer is no since when the light returns it will still be white. If a tree falls in a forest and there is nobody around to here it crash it still makes a sound. A white surface in the dark is no better at absorbing radiant heat than it would be in the light. Inside my PC it is dark and you are of the opinion that painting it black would be benificial so in a way you have answer your own question have you not?
In addition the black paint should ideally be a good conductor of heat but because the layer is very thin the conductivity is probably of little consequence. Below the paint the metal is still silver but the method of transfer is now conductivity so heat is not reflected (I might come back to that later). The bond between the layer of paint is obviously a factor in the same way a good bond between CPU and heat sink is important. How much of a facter I do not know but some coatings must be better than others and there must be coatings specifically designed for this purpose.
I do not know what you mean by dissipate in this situation. To me dissipate means to spread out like RAM heat spreaders dissipate heat over a larger surface area. How does dissipate apply to radiant heat? To spread heat the case would be copper, aluminium or steel in that order of preference. The outside of the case should have a large surface are to maximise convective heat loss again but the temperature differential is small to make it not worth the while and the surface already large. The outside of my PC should be white... I guess.
Now so as not to hi-jack the my rooms is too hot thread I now have a posative suggestion to stay cool. Wear a loose fitting black robe next to the skin with a white outer robe over the top. Look at other hot coutries and traditionally the clothing layers worn to stay cool. I know jeans and T shirt are the universal constant but ptobably not what will functional best.
