The only thing that really is preventing me from that currently is the fact that I got my Antec 1200 only a year ago or so.

When I open the front door of my case, the noise levels increase noticeably just because of the sound's more direct path. Yes, internal cooling should be quieter, assuming you can utilize the same or fewer fans at the same speeds. HOWEVER (!) fan grills can do increase noise and some things might vibrate slightly (i.e. side panels). There's no simple answer, lots of variables.

I think the Coolink is a lot louder at max RPM than the NoiseBlocker, but not sure.

I assumed so. I would end up spending hundreds more of euros on sound dampening and decoupling and a new case, so I should stick to the external rad idea.

BTW, if there are confusions about my water cooling idea, there is a link in my signature to it. Has a nice diagram too, so it should take only a minute or two to comprehend.

The Multiframes and the BeQuit Silent Wings Usc have by far the best bearings IMO. Run them @800 rpm or lower and you are a Happy man.

Neat. Since you're water cooling both CPU and GPU's, there's really not much to cool for the case fans. IMO 1500 RPM fans are LOUD when sitting in a room by yourself, no music or games blasting. You could throw in some ~800 RPM fans and not have to worry about controlling them. Wind movement makes noise regardless of bearings and remember that more fans will lead to more noise.
Quote:
A 10 dB difference is generally perceived as being twice or half as loud.
Sounds are additive, but not in a simple linear way.
Two 30 dB noise sources make 33 dB
Four 30 dB noise sources make 36 dB
Eight 30 dB noise sources make 39 dB
Sixteen 30 dB noise sources make 42 dB

So, take the noise of one of the fans you want in your case and multiply it's noise by 1.5 and you'll have roughly the actual noise those 5 fans make. Five relatively quiet fans might suddenly become fairly noisy. 1500 RPM fans will be noisy and unnecessary, 600-800 RPM fans are a better bet. Then you can save the money for the fan control and use that on the radiator fans or whatever.

Because if I can I will avoid it. -IF- that is the way to silence however, I don't want to contradict myself, since thats what I am asking for. wackosmiley.gif

There's better options than Noctua, at least for multipurpose fans. They're good but not the final word. The NF-F12 is a good option for the rad, and very quiet under 1k rpm, at least in my experience.

You're right about inaudible fans not existing, though some of them can be effectively inaudible at certain speeds depending on placement/case/distance. People who claim some 1500rpm fan is "silent even at full speed" are exaggerating, to put it nicely. I have never used a fan that didn't make itself very known over 1200rpm, no matter the case or location.

Just some ideas, mostly regarding noise:

BeQuiet Dark Wings/Silent Wings have a very good reputation, but I can't vouch for them.
Enermax T.B. Silence (or Vegas, Apollish) is good, but not a good horizontal fan per my experience (clicks).
Noctua NF-P12s are quiet under 900rpm and fairly good medium performance case fans. Very solid build quality and no worries about motor noise, clicking etc.
My Gentle Typhoon AP-13 is effectively silent under 900 mounted as rear exhaust, but noisy bearings/motor are not uncommon and can be luck of the draw. My AP-14 whines.
The Sharkoon Silent Eagle is excellent acoustically, has very nice features and is pretty solid airflow.
The Noiseblocker Multiframes have possibly the best noise:airflow ratios in open air/light restriction of any fan I've tried. Very smooth, high quality fans. Probably not the best option for rads, though.

Ultimately it's going to come down to your own experience.

to me the best silent Fans would be either the Multiframes or those:

the best would be to just purchase all three and judge for yourself. wink.gif
