Heat dissipation

$800 gets you a freon (sp?) cooled chassis, complete with a seperate compartment for the compressor and motor. It is supposed to be very quite. Unfortunately it is a computer chassis and is very unsightly.

those phase cooler cases can only handle around 300 watts.
Also isnt a mosfets typical maximum efficiency around 25c?

I just saw one for 750W. I am mainly interested b/c I want to put 3 or 4 channels in the same chassis for mulit-amping. I think it may work because so many mossfets will not run close to 0 c as they suggest anyway.... Put enough of them in there, and you will have around 25 c.

Are you sure on that figure, have you got a link?

I've seen many other types of computer vapour phase coolers that seem to max out on over clocked pentium 4's(eg vapochil) and these barely put out 100watts

Look under the third product - the case cooler!

Ah, well i can tell you now that the radiator, condensor or compressor isnt capable of shifting an extra 750watts of heat around on it

The best option(and.. quietest) would have to be Straight watercooling. you could purchase 2 long, decent thickness sheets of aluminium and drill a channel inside of it.. even use it as the watts of the amplifier case. Components will also be alot cheaper that a vapour phase cooler and less troublesome, there are literally hundreds of companies selling computer water cooling hardware.. pumps, piping, radiators, fans..
Ive seen computers dissipating 200watts of heat via a small radiator.. to give you an example of the radiator size:

Just picked up 80kg of heatsinks last week. With my huge inventory of heatsinks i've salvaged over the past many years, i'd be ashamed having to resort using some sort of water or fan based cooling system.

I'm using Zalman hard drive "heat pipe" cooling system for both HDs in my PC. Very nice product and the HD are completely isolated from the computer case with rubber mounts.

As for my 300 watt PC power supply, this is what i've done:

PS: SpeedFan software is an excellent program to throttle speed down your CPU fans inside your box.
