my ideas to combat heat

**MP3DUB** · 03-19-2004, 07:19 PM

I know audi's have it, but I'm sure other car companies do it too, but they have a "hot weather" package that cracks the sunroof when the vabin temp of the parked car hits a certain degree and runs a small fan to circulate the air.

is money or space an issue?

if not, water cooling holds some possiblities.

first off, AC is a special case, but generally you want to be careful about cooling anything colder than ambient, any vapor in the air will condense on anything colder than it. AC dehumidifies the air, but if humid air from somewhere else hits it... not good.

same goes for water cooling though. if you are water cooling, and the trunk is filled with hot humid air, it will condense, you can combat this with neoprene though.

whatever you do remember rule 1. the heat has to go somewhere.

I guess the best place is outside, as outside will be cooler than inside...

to be stationary and still cool, you need to use a fan. multiple fans infact to have any chance of cooling a 100+degree area and venting to a 90 degree area. also going to need surface area.

Im thinking 2-3 fans, straped to a large automotive radiator. but still gonna take a few minutes of circulation to cool it.

I think generally you have 2 areas both of which are too hot for a PC, no where to vent. you need to reduce the heat put out. somehow.

as stated many times (in this thread), I have an Epia motherboard. There are no watercooling solutions for Epia.

my temporary, ghetto-fied solution

I was at Lowe's looking for some ductwork for this project, and got that thing instead.

Stick some neons on it and it will look <fill in word of choice here>

Couple side notes on this whole subject. Keep in mind if you are having issues with your computer booting in your 100 degree trunk water cooling will only help if you have the hot side of the system in a place with temps below 100 degrees.

I have yet to test it but it seems to me the best solution would be to use the peltier cooling like they have in the little coolers. A few years back(like p1 days) they used to make peltier computer heat sinks so this idea cant be totally flawed. I got one of those little coolers over the summer for like 10$ and eventually just decided to tear it apart so i am looking at all the pieces right now. there are a couple advantages... 1, it runs on a 12 volt power suppy so you can wire it straight into the car electrical system, pretty simple. 2 this would allow you to get temperatures that are actually get temperatures that are lower than the surrounding air.

I know a couple people mentioned that these things produce lots of condensation and i agree with them, they are right. But would it be the hardest thing in the world to position so that it just isnt over anything important? from my observations, water only ever falls down, so if you say mounted it on the side of your case over the mobo you shouldnt have any problems.

thats just my 2 cents

I'm sorry Wizard, but LOL!

THAT IS WAY GHETTO

you can make a water block
its not that hard

dont be sorry, I laugh my *** off everytime I look at it

hey, check in your trunk (or boot as i know it :P). I had a renault 21 and it had some butterfly valves there already. They went to inside the rear guard.

I posted my thoughts on tecs on the previous page, but maybe i wasn't clear in my thoughts (as i tend to ramble

), but to sum it up, if a wc setup doesnt have anywhere to dump the thermal load, a tec will have even less. and tecs were never used as mainstream cooling solutions, as to disipate the thermal load from a desktop processor (intel/amd) there has to be cold plates, insulation, and generally a wc cooling loop to keep the tec cool, basically the same amount of work to use a phase change system. Which is the one idea that hasnt been brought up, a self contained phasechange system in the trunk. And wizard, with a bit of elbow grease, even if a wc setup isnt made for a epia, you could probabl use a chipset block and some thermal epoxy.
