    Cool

    I have two fans in my system. One on the case, one on the CPU. I have drilled ventalation holes near the HD and power supply and never had any heat problems. In fact, I could probably lose the CPU fan (it isn't spinning very well anyway) and just use the main fan as it is right above the CPU. See the link on "Player" in my sig for pictures. For what it's worth, this has run through very hot summers, for hours on end, in the sunlight, with the car turned off and all windows up. I don't have an air conditioner.

    You might want to try something like this:

    Card Coller XT 120 mm fan (2)

    Card Cooler XT Review


    The Card Cooler XT easily covers all your card slots and part of your CPU. This beast may not be for everyone, one thing I noticed is that in smaller cases it simply won't fit, so be sure to measure the space first! The Card Cooler XT really fits the job of circulating the air over the PCI/AGP cards in a system and keeping them a lot cooler.

    moahdib Hmm i wasn't talking about cooling the CPU. I was talking about cooling the computer CASE itself.
    Well I don't know why you want to cool hte case? Should you worry about CPU?

    And one more thing, if you guys use fans to cool down the computer (CPU) , the Temp will only goes down 1-2 C Max. than the room/truck temp. And some case, it will increse the computer temp. (fan motor will also make heat)

    so if the truck temp is >100F , well using fans will not help computer.

    it's just like oven!

    well I heard about thermoelectric cooler , but I don't know how well it works.
    Or use water cooling system, I saw it in the one website and I though it was really cool idea. I'm sorry I don;t have a address for that but I'm sure you can find it using search engin.

    You have to remember that you can't use a peltier, fans, or a car fridge without a supply of relatively cooler air. If you seal your box up, the air in the box will become tremendously hot. After a few minutes, using a peltier will be worse than a plain open system. A car fridge has the same problem... You will simply heat up the air inside the car w/o circulation from a cooler source.

    The air outside the car, even if it's over 100deg f, will be cooler than a processor. That's the key.

    Question

    Pato, Im lost a little bit on your comment. Air conditioners cool air right?? So if it is hot in a room and you put an AC unit it it...you are saying it wont cool off the room?? I made the comment about getting a car fridge going...i still dont understand why this wont work. It cools air it sucks into it and then Ill blow that air into the computer through a fan and a tube. I understand that a fan wont do anything cause you are just blowing hot air back onto it...but a car fridge will create cooler air wont it?? Why not if so?

    I don't understand you PaTO, cooling down the whole system will also cool down the CPU. If the temp in the case is like 90F, having the greatest heatsink and a 5000rpm fan on the CPU will not help at all. What I was thinking of doing is adding a TEC peltier with 2 fans to work as an A/C system to cool the system with no air exchange between the case and the ambient. Here is what it would look like...



    The peltier COOL side is inside the case, the hot side is OUTSIDE...get it?? and no air exchange... ( is this so hard to understand???) please go here and read what I am talking about..

    A refrigerator doesn't magically create cool air out of hot air.

    Refrigerators and air conditioners are essentially heat *exchangers*. They move heat from one place to another. The place they move it from gets cooler, the place they move it to gets hotter.

    With an air conditioner in a home, one side of the AC points out the window. Heat is taken from the inside and sent outside. No heat actually 'disappears'. Same with a car AC, the heat is transferred to the radiator, where it is then transferred to the air. Same with a fridge. Heat is taken from inside the fridge and moved to the outside of the fridge, which is why you feel warm air coming out the back/bottom of a fridge.

    So, what's being said is that if you take a fridge or peltier and put it in your trunk, unless it vents the hot air OUT of the trunk, it will make the computer cold but massively heat the trunk. And because a computer case is not heavily insulated and not designed to keep heat out, the heat will go right back into the computer and heat it up again.

    And then, because all equipment we make is inefficient, which means that we don't actuallly cool off as much as we heat up, you'll actually be INCREASING the heat level in the computer.

    A peltier/fridge will move the heat from the inside of the comp to the outside (your trunk), and in the process of doing so, creates its own heat. The heat it moves from the computer and it creates while doing the work, will heat up the trunk, which will in turn heat the computer.

    Gotchya, thanks for the clearup. So basically the answer to all our problems is cutting a hole in the car somewhere and directing air in and out of it?

    Well guys, seems like you forgot about one problem. you also have to think about over cooling.

    when the in side of computer temp reaches the 'dew point' , water will start to form and it might cause short-circuit.

    It could happen in the morning even in the summer time.
