Total silent computer

[tensop]

Thank you all for your response.

I'm currently working on a fanless computer project. The first and the hardest is the PS. I have it almost done until test time. After I plug in the PS. The live voltage on the Power transistor knock thru my non conducting glue to the water block and burn the fuse and a few transistor. Oh well, back to square one. I learn and will do again on the next PS. Attached is a pics of the burn PS.

Anybody know how to remove these transistor from the water block. It is stuck now and I want to save the water block for the next PS

PS: attached is the picture show how I did it.

OMG BE CAREFUL THOSE ARE SWITCHING MOSFETS !$!!!

but besides that, you need Silicon insulated pads(looks like plastic, but aint) or Fibreglass pressure pads, and they need to be screwed down into the waterblock, you also need to use nylon insulators around the screw hole, to compleltely electricly insulate the mosfets, and what looks to be 2 to220 packaged diodes from contacting metal and shorting to other things

If you really want a silent pc, go and ask your physics teacher how to do it. We had something in physics that you can cancel out sound waves with certain other sound wave ... so your computer would be perfectly silent.

This methode is also used bei helicopter pilots. There hadphones have this technik to lower the noise from the blades.

Yeah, it's been discussed. The problem is that it's very difficult to get right unless you know exactly where the intended "Quiet spot" is. It might work if you wore headphones all the time though...

I agreee, really tough to do.... but maybe worth it, in industry applications where noise is a very important factor. For the home user, I'd say thsat the best bet would be the elimination of fans until total PC volume is around 15-20 Db. At this volume, you'd be able to hear yourself breathing, which is perfectly adequate.

I'd spend maybe £200 for TOTAL silence.

Total PC noise <10db would eliminate the fans from most power supplies, many heatsinks and almost all case fans.

PC cooling isn't a breeze anymore, but you don't need gale conditions. If you can do the whole thing for under 40db, you have it right.

Realistically, a quiet PC has sound mats, good ventillation, and only enough cooling to ensure stability. And of course parts built with noise as a consideration.

Speaking of total noise, is:
20db(fan1) + 20db(fan2) = 30db(total)
true because dbs as logarithmic?

None, Silent...hmmmm......

That is a tuff one. If the technology was not "Brand New"
and be cost effective. Probably the same. $500.oo or so.

Seems my cheap-O (that's )H20 system is running me there now. And the loudest thing is the 108cfm 120mm rad fan.

So, yeah, 'bout $500 I guess.

What about using both sides of your computer as a large radiator. I think that shoud work. Imagine each side pannel is a large passive heasink and you watercool everything in your box. Here is one example

Then the noise would only be from Hardrive and CDROM. CDROM is not running all the time. what's left is hardrive and you can place the hardrive in a box watercool like what G33K did.

I know this will work b/c I did partially already (see the copper coil pics above)

Question is what noise level would your comp be then. I guess it would be 10dB which is silent to me

If I could have bought silence at a cost I'm not sure how much I'd pay probably a lot more than £500. What did it cost me to get silence? not sure as I had so much of the stuff I used anyway.

Either way I'm very happy with the results..... Zero fans, remote pump, only item that makes a noise is the HDD, and that is a Seagate Barracuda IV rated at 20db...... all I can hear now is the faint hum of the cathode ray tube in my monitor if I really strain.
