Most quiet route to wcing

[breathemetal]

So Id like to wc my future i7 and possibly a 4890.

I know wc can be quiet, but idk how quiet it really is.

So what would be the most quiet/near silent way to cool those without a huge loss in performance?

Passively?

SFLEX's 1200RPM 120x25fans with fan controller, undervolt to 800RPM (8.7dBA) and you can't hear it.

Only the pump(s) and fans on the radiator make noise in water cooling. With a very quiet pump and low speed, quiet fans you'll get a very silent system. Noise is very subjective, and it's impossible for me to say what you will find quiet. In general, the lower speed fans you run, the more and/or larger radiators you need to keep the same temperature. Most of the common pumps are relatively quiet when mounted correctly, but some think they are too noisy and opt for a weaker, quieter pump.

I'd really recommend you read the stickies to get a feel for how everything works and what parts are available.

Passively cool an i7 and HD4890? Not in this lifetime. The quietest way would be an internal water-cooling solution.

Run some Scythe S-Flex at 5v on a PA120.3 and a DDC 18w with vibration base was basically silent.

im running 2x 18w DCC's on my rig, and they are the only things that make a sound....but im not running them on an anti vibration mount, and im running them with the sides of my computer off....does this make that much differnece?

gentle typhoons @ ~1400rpm on an xspc RX series radiator. /thread.

Well seemed to make it dead silent. Just the faint whirl as the water was pumped around.

Watercooling is a great way to silence a computer, and as a subjective point of reference, you will not hear a quiet watercooling setup over the sound of your hard drives spinning (Just spinning, not even counting the head chatter).

My suggestion is to go with a variable speed MCP655 (Or other Laing D5 Vario equivalent) pump, because you can tune it to be as good performance vs noise for your taste (though I still can't hear mine at top speed of 5). I would also suggest Swiftech or the XSPC RX-series radiators, because they have the best low-density fin design radiators, so the fans you choose do not have to be as high pressure as a high-density radiator (The Swiftech being better price and space conscious design, while the XSPC having better cooling). For an i7 and an HD4890 I would suggest a 360mm radiator as long as you do no Overclocking (which you prolly want to avoid if going for a silent PC anyway). For fans, just make sure you get something designed for low-noise, and slower RPMs, don't try slowing down a high-speed, high-CFM fan and expect great results. Fans are typically tuned for their native RPM. For this reason, I like to suggest Noctua NF-P series fans, but they are WAY too expensive, so they are only a price-is-no-object option. I have heard good things about Scythe S-Flex S-FDB series from others on these forums though.

I think the chlorine would eat at your blocks and fittings ;)

[ben805]

hmm...i find my medium speed 1600rpm Scythe S-Flex F pretty quite, I run them full speed in push, and pull by the 20mm Yate Loon low speed. ;)

20mm ? That is one tiny fan ! :D

(I assume you meant 20cm ;))

[Brad8988]

He means 120mm/20mm slim yates i think.

I think NaeKuh's loop/loops would make the pool water unbearable to swim in :rofl:

But seriously, A ddc3.2 or 3.1 and some GT's 1450rpm model. Thats about as quiet as it gets. You can always use neoprene and stuff to silence you computer even more.

[Brad8988]

My last lian was fully sound proofed and had a door. Was very very quiet and you could really tell the difference with the door open or shut. Made a big difference.

[WatZp]

How about yate loon 1350 rpm, is it quiet enough?

Depends on "enough". And what goals you have. Check this (http://www.xtremesystems.org/forums/showthread.php?t=223391) thread. You can listen A LOT of fans there :bows: Martin :bows:

Thanks Brodholm.:)

The MORA2 could do it cool that load passively

I actually thought he was talking about passive heat-sinks when I first replied. Didn't realize he probably meant a passive radiator in a water-cooling setup. Oops. :hitself:

I'm running the MCP655 at various speeds with 4 s-flex e fans and a nf-p all @ 5V. I can't hear them. Loudest thing is my pump, which I have resting on a "cushion". It can barely be heard, but is definitely noticeable. But the moment I open a window or start listening to some music or do anything that makes noise I can't hear my computer at all. My HDDs are suspended so they don't make much noise. The odd seeking noise is all I hear and that doesn't come often.

[voigts]

My setup is at whisper sound levels. I run a DDC 1 (now DDC3.1) with Yate Loon D12SL-12 fans all undervolted at about 7v on a Sunbeam controller. Using two MCR320 rads allows me to turn the fans way down like this with no sacrifice in temps. My hard drives are without a doubt the loudest thing.

[YMAA]

I've found running a restrictive loop is a good way to quiet a pump. I have a Supreme with a Fuzion GFX2 and two rads and the pump seems quieter with the Supreme installed than with my old Sapphire Rev A.

Oh, and low-speed Yates are fairly quiet on the cheap. Scythe S-Flexes and (especially) the newer Noctuas seem to be the most quiet...but they cost a pretty penny.

They make them that thin ?! Holy bajeezus !

Swim ? It just needs to be called a hot tub ;)
