Put together this relatively quiet and discreet air-cooled system with the aim of supporting VR and 4K graphics. The Fractal R5 stock rear fan was moved to the lower front intake position and a grey Noctua PWM fan positioned as rear exhaust. All case fans are connected to, and controlled by, the motherboard rather than the case fan switch. All parts perform as advertised and the case and compact modular power supply made assembly easy. Fitting the H7 cooler was fiddlier than expected and the method of connecting front I/O on the Asus motherboard hasn't improved from six years ago, but the feature set on this motherboard is otherwise excellent.

Part Reviews


Good but soon to be superseded by Coffee Lake

CPU Cooler

Quiet, compact, performs well for its size and weight, looks good, good price.


Good feature set but soon to be superseded when Coffee Lake is introduced.


Works at advertised speed with XMP enabled on Z270E


Fast. Very Fast. Did I mention it is fast? And a bit expensive.


Cheaper than a 2TB SSD. As hard drives go it performs well enough.

Video Card

Astonishing performance. Fans stay off (silent) below 6o °C threshold.


Case needs no introduction. Versatile and easy to work with. Quiet features. Easy access dust filtration.

Power Supply

Compact, quiet, fully modular, 10 year warranty. Ideal.

Optical Drive

Works fine. A bit noisy but not used very often these days.

Case Fan

PWM keeps rpm and noise low but if set to full speed (mine goes up to 1300rpm) it is not quiet. Two tone grey of the Noctua Redux matches aesthetics better than brown Noctua fans.

How's the noise level on this case? I'm thinking of using it in a 1080 ti build as well, I'm curious what level of noise the stock r5 case fans put out...any tips?

The stock case fans are voltage controlled by the motherboard in my system. At idle temperatures they spin around 580rpm and at full setting around 900rpm (curiously not 1000rpm). I would class them as quiet. At full speed they are much quieter than the Noctua redux at 1200rpm but given the speed difference that is hardly surprising. However the Noctua spins below 400rpm at idle temperatures. In hindsight I would have been happy ordering another of the Fractal fans rather than the Noctua.

I can tell when the HDD spins up or is idle within the Fractal R5, so one day when prices are lower the spinning hard drive will be replaced by a large capacity SSD. Similarly the 1080Ti fans can be heard when running benchmarks as can the CPU cooler fan when stressed - sound will always escape from the rear of any case. But I can live with that trade-off between cooling and the sound of air movement.

hey thanks for the breakdown, really appreciate it. I guess I'll be looking to slap one of the stock fractal fans up front under the other one.

https://pcpartpicker.com/user/SquelchMuffins/saved/xyj3CJ hows this look for a quiet, minimalist build?

I'll reply in your linked page.

If I may ask, because I am looking to build a pc with the same power supply and graphics card combo, how you connected the 1080 Ti to the SuperNova. Because as I'm sure you know the 1080 Ti has an 8 plus a 6 pin connector, but the G3 only has 8 pin VGA outputs. Did you just get a 6 pin cable and plug it into the 8 pin slot? Or did you use one of the cables included with the PSU, because I noticed it comes with a 6+2 cable, so if you used that the remaining 2 pins would just be hanging freely. At any rate, how did you power the 1080 Ti from the G3? And sorry for my long-windedness.

On the fully modular EVGA 750 G3 power supply there are four outlets for VGA cables. There are four VGA cables supplied - two with single 6+2 connections and two with dual 6+2 connections. If you read jonnyGURU's review of the EVGA 750G3 (page 2) they advise using two of the single 6+2 cables to power high-end graphics cards - and that is what I did. There are two pins loose of course as only 8pin & 6pin connections on the graphics card are needed. In picture #3 above you can just see them tucked between the pcie cables near the graphics card.

Ahh, many thanks, and nice build by the way.
