So you keep on saying... but this is the Watercooling section... Well, Marci. This would be why i believe it's hardly off topic to suggest air in the w/c section: Watercooling or not? You keep telling everybody to get a single Thermochill. I keep telling them it's not as quiet as a good air cooling...

Not in this case, since space is limited.

The benefit of (active) watercooling is basically that you can move the heat a couple of centimeters and blow it away through a rad instead of a heatsink on the cpu. If you have the rad blowing the heat into the case, then what's the point? Marci and me have already debated this one / two rad issue....

5v YateLoon would be 10dBA... s'about as quiet as it gets... 10 decibels? I doubt you can even start a Yate Loon without producing more noise. At 5 volts, even a Nexus hanging in free air makes clearly audible noise in a normal room in a city apartment. Adding a radiator, even if with widely spread...

Is it the DDC you talk about? Or some other version?
Oh, also I should say that I ran it from my Fan-O-Matic with no problems.

My DDC starts @ 8V. It's loud as hell compared to an Eheim 1048, but vibrates much less. I stopped using it because the sound is so hard to dampen. Apart from completely de-coupling it, I covered it in cellfoam and cast it all into a block of cement, but it was still the loudest part of the system. ...

But a 5 V YL fan on a rad makes more noise alone than a whole computer made around Nexus fans, state of the art air heatsinks and active fan control.

Some products have soft "thermal material linings" that conduct heat, like the stripes you find in a Drive-A-Way HDD case. So here's for all you know-it-alls that hang around here: What kind of material is that anyways? Can I find something similar anywhere? Are these soft materials good for heat tr...

The MX 5000 keyboard is rather quiet and has a superb "feel". Well-built feel and almost no rattling or hollow plastic sounds.

Stick with air. Get a T-balancer and enjoy the silence.

Ah well. First my card is too slow. Then I say there are faster passive cards if you really need them but that it's probably overkill as it is. Damned if I do and damned if I don't. :) Regardless, I think you're right about the reason for going active. That and to keep it simple. What do I know abou...

KeepItSimple-something??

Building the duct in softer foam material should cut just a little noise coming out of the front. Not really. There is no difference listening to the PSU from the front or the back of the case. It's very quiet. Nitpicking, but that's exactly my point. When I changed from cardboard to foam less soun...

Excellent build! I didn't read through all the post and can only hope I'm not parrotting something here. Admins, please just delete this if so. Just some thoughts, not intended to be impudent: Building the duct in softer foam material should cut just a little noise coming out of the front. A T-balan...

Oh, another thing always coming up in the forums is the pump vibration problem. Rubber studs, cellfoam pads and similar isn't good enough if you aim for silence. I keep recommending folks to completetely de-couple the pump by hanging it in long silicon cords and using long soft water tubing at inlet...

Rubber/cotton mounts/feet won't catch the fish. To completetly de-couple, hang the pump in long silicon cords and use very soft water tubing at inlet and outlet. Then you can kiss the vibrations goodbye and use heavy sound isolation to finish it up.

This has been tried since long. Still running!

Excellent! Thank you CA_Steve!

Says there is a heatsink in it. This is a heatsink, with TECs, connected to the CPU through liquid stuff and a pump basically? Water cooling, except not actual water. Or just a hoax?

Just updating. You can now buy the Nexus 120 in Black and Off White colour scheme.

Only one fan will directly suck air through a radiator. Nothing will be force-feeding it. The whole concept is to let negative case pressure do the work, especially in the passive rad at the front of the case. The plan is to have only the two rear exhaust fans (rear and top) running at 5v, the rear...

As an example, here's what my fan setup would look like for me to be satisfied with air cooling in the P180: 2x Yate Loon 120mm @5v exhaust, 1x Yate Loon @ 8-12v (uGuru controlled) CPU and OTES cooling, 1x 80mm fan (assuming VF700Cu or V-1 Ultra) GPU, 1x 80mm fan PSU. Contrast that with the above w...

If money is no object, also check out the Innovatek Fan-O-Matic!

I use my 555-ES mostly as transport for cd's as SACD recordings are rare. Anybody knows if I can use my PC to store DVD-A material? Lossless of course.

I'm not pretending to understand even half of what all you smart people have written in this thread. But I had this thought I'd like to share with you. By all means hack me to shreads if I'm wrong. Concerning the one vs two fan debate: One (~12V) fan has to accelerate air to double the speed of two ...

That's nice work on the pump there. Did you do that yourself? Impressive! Mine looks like the sort of brown lump you can occasionally step into while walking the curb. Does the acrylic casting help much? My cellfoam and cement solution was so-so. I have missed SPCR formally stating <30dB to be consi...

Should we call a pump that makes more noise than a Papst 4412 @ 12 V quiet? The Eheim 1048 is way quieter than that. And the Eheim still needs isolation or it contributes hearable noise in a system built around Nexus fans under 5V. Maybe the much talked about individual variations supposed to be fou...

omaticrail, this misunderstanding is likely due to different noise standards in Procooling vs SPCR. My DDC is noisy like hell, compared to my 1048, but its vibrations are like a fart in space compared to any Eheim pump. That's why, if you don't see to it and hang your Eheim in elastic silicon string...

Mine stopped under 8V. Still noisy. At 12V it screams. (Everything compared to the 4412s at 3.3V.)

No, I'm sure of it now. I don't like my DDC anymore. Quit using it. Too loud.
