Im building a homemade projector out of a overhead projector and lcd screen. There is alot of heat involved so cooling is a must. But i not want loud fans so id like to be able to maybe comeup with some type of liquid cooled application for the lcd screen and the overhead. Involving the least noise as possable. Any suggestions would be great.

I have been looking at liquid cooling kits for computer and tring to see how hard it would be to take on of them and change in it what i need. But i figured some of you guys might have more experance with the kits and be able to give me some better suggestions.

Thanks Eric,

For an overhead projector, I think you're going to be stuck with at least one fan for the LCD panel. I can't think of any way to transfer the heat away from the LCD other than blowing air across it.

Then there's the lamp inside the projector, which the projector's fan is supposed to keep cool. Again, not sure how you'd cool a lamp like that without moving air across it.

CPUs are much better suited for watercooling since you can actually make physical contact with the hot component and draw the heat away. In both the case of the LCD and the projector lamp, making physical contact with the hot components will render them useless by blocking the light.

With that in mind, I would suggest instead investigating quieter fans instead of liquid cooling. Vantec's "Stealth" series of 120mm fans are incredibly quiet, and would probably work great for cooling the interior of the projector.

With some clever ducting, you might even be able to do something like draw cool air over the LCD and exhaust that air into the projector chassis with one 120mm fan, then use a second 120mm fan on the other side of the projector to exhaust the hot air, thus cooling the entire setup with two sufficiently quiet 120mm fans.

That is probly what i will half to do. I got the projector in today and it had a fan in it already that was suprisenly quiet. the only thing i did notice is after it runs forawhile it starts to get a burnt smell to it. Not sure if there is going to be any way to fix this problem. right now my biggest problem is when i took my viewsonic 14.1" lcd apart i ran into a big problem. The control board for the lcd is connected with 2 connectors. one of them from the top of the lcd and one of them from the side of the lcd. Somehow i gotta find a way to expand the one from the side so i can move the control board out of the way of the light. ill post some pics later 2 night to explain the problem better. Unforentually im gonna half to try and fabricate a plug for it. If i aint i will half to buy a diffrent lcd.

I was just thinking. Take a water cooling unit. Get a aluminum coil. Hook the water cooler up to it. And then put a small fan behind it. And then pipe that over lamp in the overhead. and then pipe it back into aluminum coil. So the air cirulates acrost the lamp. Any suggestions. I have no idea if this would world but it would solve the problem of the lamp put off a burn smell. You could also do the same with the overhead.

a little off topic and a bit extreme, but i seen some guy build a home made liquid nitrogen cooling system in his home made "super computer"


if you did a liquid system, your going to have to figure out a system to make he water cold, which might just make some noise as well

i sugest runing a liqiud cooling sestem thru it with the coils it might work no garntees... with fans blowing the air to the light
