Projector fan noise? Liquid cooling?
I have a Sony VPL FX51 projector that emits about 32db of fan noise due to it's brightness. Does anyone know of any techniquies to lessen fan noise without lowering the fan rpm's and risking overheating? Some new projectors come with a liquid cooling system which greatly decreases the need for a fan. Are there any liquid cooling kits that would work? Any ideas would be appreciated. Thanks!!
It doesn't have an economy lamp mode. It has High and Standard... it's already on standard. The hush box and venting are good ideas but can't really work in the space that it's in right now. I might use the hush box concept with just a base. We'll see how it works. Thanks everyone!!

This used to be a common problem with older (noisier) projectors. The usual was to build an enclosure called a "hush box". Google it under that name. Here is a link to one example

You really cant liquid cool the lamp in a projector. The best solution is to duct the exhaust port out of the area. There are companies that make systems of exactly what you need. You take out the projectors fan and then attach a duct to it and there is a fan at the other end to vent it into a remote location. Just be sure where you vent it the air can escape other wise your just pressurizing a space and then the system will fail.

I had a liquid cooled system on my PB 8600 and I didn't really notice a diffrent. still shut off at about the same time. I put two fans blowing on it. One going towards the air intake and one just under it to cool the hottest part of the projector I found. they were $5 fans from Wal*Mart.

The fan noise on the FX51 when the brightness is set to "normal" is downright intolerable. However, should you set it to the econ or "low" light setting, there's a noticeable drop in fan noise, along with diminished brightness. So, there will be a tradeoff: low fan noise with a slight darkened image.
Good luck!
