Does Your Computer Sound Like a Jet Engine?????

Well I put the Beaver tail all over the inside of the case and it did help. However to much noise from the CPU fan is going out the rear exauhst fan and power supply.

Ctyler,
I also tried the case silencing thing and I ran into to the same obstacle as you... The sound will seep out of the output fan!!! But I did find that lining the inside of the case with thick carpet padding did have some effect and was FREE! I once tried to build a muffler for the output fan on the power supply and case fan but this was a total flop :) Probably because the only material I had was cardboard...Man Alive!!!

Oh, water is the way to go.
I'm using a 250 GPH Danner with a Danger Den Maze 2 (my home made block worked quite well until the lexan split...) and the standard Chevette heater core, plumbed in 1/2", although I'll probably go 5/8" for the short run from the radiator to the pump intake.

I had my EYHJA pretty happy at around 1600 (11.5 x 140) as long as I kept the room cool.
Oh, and of course it's quiet.
Man, this beats end user audio hands down for exclusive sounding discussion!

Don't laugh about that a few years back Cadilliac had the brilliant idea of using water cooled alternators in the Seville. Well after a few of them burned to the ground and a few houses burned down(no injuries, thank god) they ordered a SERIOUS recall and told all seville owners to park there cars outside of there house preferably on the street and disconect the battery and wait for a flat bed to take the vehicle to the dealership and have a non-liquid cooled alternator installed. I think that brilliance deserves a nomination for the Darwin awards for the engineer whom thought of that one, two thumbs up buddy! The only reason I know this(GM kept this VERY quiet) is me and a friend bought new Cadilliacs at the same time I got the catera and he got the seville and they are both horrible cars, just a matter of which is worse, needless to say after that problem he got rid of his and then I got rid of mine. Moral of the story is water cooled electronics=bad idea.

I took a sigorski motor and mounted it to my wall and have it drawing air out of the room away from my computer, so it stays cool. FWIW I only run the engine when I am out of the room, sucks everything through the blades untill I installed a shrowd. So again moral of the story like a good porsche a computer should be air cooled!

Yes, and my solution was to have a dedicated room built for it.
