Description

I've been looking forward to a new PC for quite a while. My old PC is just too loud and overheating problems shut it down frequently in summer.

After I moved to Irvine, I discovered that Micro Center is just a few blocks away. So I got i5 4690K and AsRock Z97 extreme 4 combo at a low price. After $30 combo discount and $10 mail in rebate, the mother board is only $89. It's a good deal.

To lower noise level, I tried to use quieter cooling devices and lower the temperature at the same time. At first I have considered a completely fanless build. However, the fanless CPU cooler has to maintain a high CPU temperature, which will raise the overall temperature inside the case. So, instead of a huge fanless CPU cooler, I decide to go with Noctua U9S. It is definitely an overkill. As for PSU, I finally chose Seasonic 520FL2. I don't think a regular PSU can cool down better inside NZXT S340 case since the PSU is isolated by a 'roof top'. Actually, the PSU turns out to be cool all the time (so don't worry if you are considering H440 or S340 with fanless PSUs).

Some review says that Inno3D GTX970 Ultra version is the coolest one. Sadly I cannot find one in the US. So I used Gigabyte WF OC3 instead. The fan noise is acceptable; I played COD10 at highest video settings in 2560 x 1080 for about 2 hours and the GPU temperature is still 35 degree according to GPUZ.

Hi, may I ask that why, when building a quiet PC that you went for a case with a plastic side? This is one of the main areas of noise transfer from within the PC. The Fractal Design Define R5 comes in white and would have been a better choice in my humble opinion.

The ASUS Strix and MSI 970 aftermarket coolers both have fan-stop technology that stop the fans on the GPU when they don't need to be run. This also would have reduced noise.

The Seasonic PSU was a pretty good choice in terms of quietness. If you want a 'basically' silent PSU that has a bigger overhead then go for a Corsair RM750i in the future if you want to ugprade.

That CPU cooler is also a bit overkill. The Coolermaster Hyper 212 EVO is much cheaper and completely silent at 100% load. Also it's basically just as good at cooling.

i dont know why but i love that case and i will probably use it in my next build :)

With all due respect the fanless platinum Seasonic 520 is is an ideal choice for this build. It offers very tight voltage regulation and will operate more efficiently at the load drawn from this system than a unit designed to deliver 750 watts.

The NH-U9S uses a 92mm fan and is a smaller unit than the 120mm 212 Evo you suggest.

Myself and many others dream of a non passive cooler which is 'completely silent' - let alone at 100% load.

Nice build +1

Entirely fanless builds are not always silent. There's a lot more to take into consideration than just moving fans. A very large amount of entirely fanless PSUs output a ridiculous amount of 'coil whine' and electrical noise. Whilst fans can be turned down and generally even at high speeds can still remain silent due to the 'type' of noise that they produce. Electrical noise through either vibrating coils or caps isn't something that is generally easily silenced. Seasonic PSUs (especially the fanless ones) are very well known for their coil whine.

In particular the Seasonic 520 is one of the few that can make a lot of electrical noise: 1. [removed] (Comment 3) 2. [removed] (Post 7)

Almost nothing is more important to me than silence and I've probably spent a longer combined time than anything else researching on what are the most silent components available for my builds.

My bad, didn't realise I wasn't allowed to as I couldn't see it anywhere in the rules. Some of those links were just really long.

Indeed fanless PSU's are not always silent, one of the two fanless Seasonic 520's I own does emit an amount of coil whine, usually when cross loaded, that is a fair statement which you have obviously heard from internet sources.

Did all your 'value'd research lead to to find the 'Coolermaster Hyper 212 EVO is completely silent at 100% load'?

I take it you mean inaudible, although you fail to state the ambient noise levels at which this is the case. I'm not saying it is a poorly performing cooler by any means but I do find your comment to be slightly misleading, particularly to novice builders taking on such advice. As a matter of personal taste I actually find the 'tone' of noise emitted by the 92mm variants of Noctua coolers to be slightly more unpleasant than 212 EVO, so essentially agree with your point just not the way in which it was made.

I think you are being a little too critical of what I am saying here. The 212 EVO is by far the best choice cooler (imo) in terms of 'quietness' vs. 'cooling potential'.

Running at 100% speed it's barely audible (if at all), especially in a soundproofed case that isn't populated with a bunch of loud/fast running fans. I am making a second build of another that I made for a friend and have tested this cooler over 4 different CPUs on 3 different mobos. The 212 EVO is silent (unless you put your ear to it) when idling or gaming and it is only audible when running at 100% speed.

The Noctua NH-D15 for example is a 'better cooler' but it is also louder and bigger. The Corsair H100i is also a 'better cooler' but it is also louder. In addition to both coolers being louder, they are also anywhere from 3½ - 5x more expensive than the 212 EVO. I am not saying that the 212 EVO is the 'perfect' cooler. But it is definitely the most 'value' option for a quiet cooler that performs excellently. At 4.8GHz it can cool an i5-4690k to under 30C at idle (where the cooler is silent, again unless you have your ear to it) and even at 100% CPU usage the cooler is never louder than even the other fans running at stock speeds.

Apologies if I am coming across at too critical, but to say it is barely audible is extremely subjective, possibly you live in a city with quite high levels of ambient background noise?

Silent is a very strong word.

I live in the countryside and the 'ridiculous' amount of coil whine you speak of coming from my Seasonic PSU sample would, to my ear of course, be considered audible within 15cm of the case (front or rear) after around 1am or so. That is with 3 120mm case fans and single 120mm cpu cooler fan running just under 400rpm. In 2 friends builds using the 212 EVO I consider its fan to be distinctly audible when running at say 80% of its rated rpm with similar case cooling in place.

Again it is a great cooler for the price point you are absolutely correct, but saying it can cool the i5-4690k to under 30 degrees centigrade is absurd if my summer room temperatures are at a toasty 28°c ambient.

I have considered R5 but NZXT is 50% cheaper. The fan is a bit overkill though. I'll definitely take your advice in my future builds.

Sorry to hear about the loud fans. Personally they drive me nuts. No worries though, and it's always a good idea to ask around and post your build here.

Today I just found that the noise in my apartment (from the fridge, bathroom and outside) is much more louder than the PC. So maybe it is not necessary for me to build a 100% silent PC... funny.
