after watercooling how much quieter?

post #1 of 11
Thread Starter 
Before I jump into watercooling I want to make sure that it is substantially quieter. I have two 290x in cf and dont enjoy the noise output. What i want to know is whether after watercooling you guys have been satisfied with the noise reduction and what kind of drop in decibel you have got out of watercooling.

you can hear a pin drop, Use Gentle typhoon fans.

My refrigerator and home plumbing is louder than my rig. Our big winix monster air filter which is almost dead silent is louder than my rig. But really, it depends on you. How loud or audible do you want it to be is the question?

WCing isn't inherently louder nor quieter than air cooling. How loud a WCing system is depends on what fans you use, just like air cooling or case cooling.

Generally, to design a "quiet" WCing system you would use large or multiple radiators so that you can use multiple, low air flow, quiet fans.
Since air is the primary heat removal medium, the more air that you move through a radiator the more heat it will remove. So using a lot of fans allows you to move a large amount of air with quieter fans, instead of using a smaller radiator with fewer fans and each fan moving a lot of air.

Then there cost. Quiet costs more money because you have to buy larger or multiple radiators and more fans for them.

It really depends on the number of fans you have running, your pump, your case, and most importantly, the ambient noise level of the room your PC is in.

With my window open, I can't hear my computer at all and I live on a quiet residential street with very little passing traffic.

However, with my windows closed, I can hear my D5 pump which is running on setting 4 I believe. I cannot hear my fans because they run at 500 rpm on idle and 1000rpm at full load (GT-AP 13). Then again, my room is acoustically treated with panels so I can really hear most little things.

Really if you run your fans sub 900rpm, you will likely only hear your pump, unless your pump runs at setting 2 or something.

Well I plan on buying the new Fractal Design Define S case with window, and installing two 360mm rads with those ek vadar fans. This is what I plan on getting:

EK EK-KIT D360-X2 Dual Radiator Drop In Liquid Cooling Kit for Caselabs x1
EK EK-ACF Fitting 10/16mm - Nickel x2
EK FC R9-290X Plexi/Nickel Rev.2 AMD GPU Waterblock x2
EK Dual Parallel 3-Slot FC Terminal x1
For drainage:
Bitspower G1/4 Matte Black Mini Valve w/ Handle x1
XSPC G1/4 Black Chrome Male to Male Rotary Fitting x1
EK G1/4 Black Socket Extender x1
XSPC G1/4 10mm 3/8" Black Chrome High Flow Barb Fitting x1
XSPC G1/4 Black Chrome Plug x1

Will it be fairly quiet with 290x in cf?

I couldn't hear my EK Vardar F4's when I tested them. My Corsair SP's got better temps and I can't hear them because they fade into the loud ambient noise of my current apartment. Once bled, the D5 is very quiet too. Mine runs full out and I don't hear it at all, but I do feel it through the desk at times.

Fans are pretty much inaudible... have them at like 600rpm.

Pumps I should probably turn down, lol.

Same here, but since mine is mounted directly to my case with no rubber dampner I get a low audible hum. Reminds me of an aquarium air pump actually. Can't hear my fans over it though and it's still quieter than air cooled, or at least the frequency is more pleasing.

i just finished my system earlier this week, and all i hear is the pump vibrating in the case, and apparent coil whine from my GPUs. sounds like a quiet fish tank, at the moment.
