I have seen articles similar to this but did a search and didn't see these exact questions. People spend a lot of money on cooling over the span of computers. Why not use central air that has zone compatibility or even these. Was looking around on the net and you can get them for as low as 600ish depending on brand, BTU, and if dual zone is needed. That may sound like a lot, but consider this, you can essentially cool every electronics item in that room just by keeping the room cooler and all you really have to do is wear maybe a sweater..Thoughts? More importantly they only require a 3 inch hole rather than the portable AC units that require the big ducts. Interesting thoughts.

BTW Hi again everyone...member from way back used to be on here by the name of Northern back when high speed internet was just getting to my little farm town in Ohio..built my first pc because of this place...missed it...couldnt find my stuff so just made a new name.

While operating computers in a cool room helps, the days are long past where the cpu was cooled by a simple large chunk of heatsink with no fan.

Remember you have to try to keep a device the size of a soda cracker putting out the heat of a 100W light bulb from exceeding aprox 70C (160ish F) in temp. The intel stock heatsink/ fan unit does this basically free with the purchase of a CPU. This heat is dumped into the room through case airflow so on a hot day in August A/C in the computer room is welcome but somehow I feel a $129 window air-conditioner would be more cost effective and in the winter the heat from the computer(s) is a bonus. You cannot cool the room enough to cool a modern cpu, of it you could, you would need more along the line of artic outerwear instead of a sweater. What I am trying to say is that it is a small device putting out a ton of heat and the only way to remove that heat fast enough is with airflow. Since the device is small it takes a lot of air to move the heat way fast enough, so a heatsink increases the surface area the air hits to help remove the heat. You would need a very big heatsink to do what you propose assuming I am understanding your intentions. Passive cooling is possbile. Take a look on silentpc.com.

This theory is simple to test, it should be fairly cold overnight in Ohio, at dawn and a day with no or very light wind, go outside with a lamp with a 100W bulb and no shade and plug it in and turn it on. Go make coffee, come back and see how hot the bulb is. Be carefull of your finger.
 
Actually I was speaking of using all the stock parts and just cooling the room more rather than buying 200+ of water cooling and such just to have to resort to changing parts and eventually buying it over and over again through technology changes. A good AC unit will last many years and would do a great deal of cooling beyond stock. I'll raise your experiment and throw one back at you.

Do your water cooling or the like in a room of about 75-80 degrees...meaning body heat..the hot air that is displaced and such...check temps and post them.
Now do stock cooling in a room about 55-60 degrees and post those temps. Let me know.
 
Do not have too, done it already.

and of course my loop temps drop significanty under lower ambient, however it does not affect my Overclock at all as I am at the maximum my particular combination of components allow. You want to wear a sweater year round, spend that kind of money for perhaps a 100MHz or so of cpu speed in the summer, thats your business. If you need to justify central air for your house using it to improve computer performance is not rational from a cost/benifits view. If you were going to buy central air anyway /shrug most of us here are aware of the funtion of ambient air temps on heatsink performance and overclocking. Howver a $60 Thermalright ultra 120 and decent fan at 80F ambient would still probally outperform the stock cooler at 65F ambient with a high overclock but if you would like to spend the money to prove otherwise, carry on.
 
Evidently I upset you in some way. Oh well I could give a. There are reviews on the much newer stock HSF so go fish. However, a 500 one unit AC to cool the entire room a few degrees for ALL of the electronics in the room as well as yourself isn't all that bad considering you will easily spend that in the next few years and the AC will keep running with it's in some cases 10 year warranty.

Yes even in the 64s they (aftermarket) were better. However, stocks keep getting better. It will only be a matter of time where even the stocks will just do fine for some OC with a decently controlled environment.
 
One thing to consider is that people are also looking for quiet cooling solutions. Stock parts in a cold room will be great at keeping temperatures under control, but stock parts are generally noisy and that's not even factoring in the noise from an AC unit.

A solution for the best of both worlds would be to put all of your computer in an adjacent room or closet with an AC unit in there and then run VGA and KB/mouse cables to your desk.
 
Wonderful idea and since the 3 inch hole is all that is needed it could work beautifully. NICE i like. Thanks, smaller room = lower ambient could even make sure it is somewhat blocked off so other rooms don't get too cold in the winter...thx
 
I had once visited a server room over at BASF and it was cold as hell that you would like to leave there immediately but there was noone staying in the room with computers. You might consider setting up a cold room for your computer but why would you breeze you ass with it?
