well cooled computer making the room hot?

[Vcize]

Ok, here's the deal...I've got a pretty decent cooling system set up...pretty decent meaning I get 28 degrees celcius as my case temp and 35 degrees processor temp on a bad day. Especially considering I live in central florida where the heat+humidity is deadly.

I'm running:
xp 2600+
8rda+
512megs corsair pc3500
80gig WD
120gig WD

just to give you an idea of the setup. It's being cooled by:

Lian Li Pc-60 aluminum case
2x 80mm front intakes
2x 80mm side fans
1x 80mm exhaust
1x 120mm blowhole
Thermaltake Volcano 9

430 watt Antec true blue psu


Anyway, here's the problem. I get good case temps, but the room the computer is in gets blazing hot. At first I thought it was just the poor insulation and small space of my apartment, but I'm home for the summer and it's even bad here.

The air coming out of the blowhole is warm (makes sense, heat rises).

The air coming out of the PSU is HOT, though it is less air getting pushed through.

Which of these is making the room so hot?

I just purchased a baybus, but will this really help any?

Should I replace all my case fans with something like panaflo L1A's (or whatever the fan that is supposedly quiet and doesn't push much air is).

Could it be the heatsink? Would upgrading that to an SK-7 and 80mm Enermax adjustable help with the room temperature?

Basically, would any of this help or do I need to just shut off the blowhole and put a book over the hole or something to prevent the hot air from passing through?

Any recommendations for something that will cool the computer (possibly not as good as it is cooled now), but keep the room at a decent temperature? I mean, I can hardly sit in here after a gaming session it's so hot, and if I walk a couple of rooms over it feels like an iceberg.

Do I need a new power supply? Anyone else have this problem with the trueblue's or is the PSU not the problem?

Help!

All that your fans and heatsinks will do is move heat from one place to another. Your options are:
- Lousy heatsinks, and poor fans, thus keeping the heat better pent up in the components themselves, eventually killing them.
- A decent heatsink, but no case fans. This will keep the hot air stuck in the case, which will in turn lower the heatsink's effectiveness. Results in thermal buildup, possibly causing instability.
- Good heatsinks, well ventilated case. The heat gets vented out of the case and into the room. Now your task lies with cooling the room. I'd recommend an air conditioner, or at least a good window fan.
Walmart should have a ~5200BTU model for under $100; 5,000BTU ones are available where I work for $90.

Do you have a CRT or LCD? The former put out quite a bit of heat...

Jeff7 nailed it. You've gotta get the hot air out of your room, either via fans, or an AC unit to convert it to cool air. I face this problem every year, since the room with the computers gets much warmer than the rest of the house. I can't justify cooling the whole house down below 70 just to keep the computer room below 75.

Buy your self "air condition", nothing else helps

I have total hell in my room after few hours when my computer is turned on, but
I have moved the case close to open window , so it blows outside But that
can be problem when it rains

 

[Vcize]

Hmm, well there's plenty of AC, and a ceiling fan in here.

Would turning off the blowhole and covering it help any, or would that air just come out of the other exhausts?

 

[huesmann]

Maybe you should put a fan in the doorway of the computer room to either blow cool air in or the warm air out. Disabling your blowhole won't help much.

Edit: Go read Jeff7's version, he basically said what I said, in a lot less verbose manner.

Disabling your blowhole would just prevent the exhausting of hot air. Some of that hot air would leave through other means in the case and some would just stay in the case. The heat that makes the hot air hot, will follow the air. Your computer is putting out a constant (simplified view) amount of heat. Heatsinks and fans just serve to move that heat away from your components and into other places, they don't actually get rid of heat, that would be against some law of thermodynamics. The heatsinks and fans move the hot air into your room. You could consider undervolting your processor to lower the amount of heat your computer puts out. You could also consider getting a bigger A/C unit to move that heat outside of your room.

I hear you car improve cooling by knocking out the windows. Seriously, to reduce heat, lower the o/c on your CPU/video. I have a Summer o/c and a Winter o/c.

I have the thing running at pretty relaxed timings...


I understand all this about heat, and it has to go somewhere...but how come I can run 3 dells in a room for 2 days without noticing the temperature change a bit, but when I run mine for 3 hours it goes up 10 degrees?

dell is bad airflow

Possibly that; what hardware are the Dell's running? Do you have the monitors on both of them as well? Someone did already mention that CRT's put out a good bit of heat when they're running.

 

[Vcize]

I'm using the same monitor on this computer that I was using on the dells. 17" trinitron CRT.

 

[BigBadBob]

Can I borrow your computer for next winter? Seriously, you need to exaust hot air out of room or air condition.

In the same room? Even if three Dells are running 500MHz Celerons, three should put out more heat than one home computer of any kind..

Heat is energy. Conservation of energy dictates that it can't disappear. At best it can be moved, hopefully where it is less troublesome, or diluted. If you confine a larger quantity of heat inside the computer, the computer will rise to a higher temperature. Heat can be delayed briefly from exiting, but ultimately the heat WILL come out.

You need air circulation, to dilute he heat density and lower the room temperature. A ceiling fan will mix the air within the room and dilute the heat some. (Primarily it moves the air, and your sweat evaporating faster makes you feel cooler.) But you need to get the air into other rooms, or turn up the AC. AC moves a net amount of heat from the inside to the outside, it doesn't cancel it out.

Since you have two HDs, one thing you can do is have Windows power management shut them down after say 5 minutes unused. That'll save a couple of watts. You have quite a few fans, which will generate a few watts of heat.

Bigger power supplies probably generate more heat than smaller ones. Usually the efficency is best when operated near its limits, and less at lower amounts, with some amount used even under no load. And I'd guess few people actually use 400 watts continuously. More like 100. A 400 watt power supply doesn't put out 400 watts unless its load is 400 watts. 400 watts is what it COULD deliver. But power supplies are not 100% efficient. For every watt they pass to the load, they pass some additional amount of watts directly into waste heat. Every device in the computer ultimately turns all the power it receives into heat. A 10 watt fan, converts 10 watts of electricity to heat.

We have 6 Dells 1.8's I think + CRT's in my dorm computer lab, that room is ALWAYS hot as crap!

They prolly got sh!tty A/C
