Silent, But Deadly: Build Your Own Gaming-Ready 0 dB PC

Motherboard: A Challenging Installation

Making Some Room and Getting Rid of Some Noise

A few issues need to be worked through before the motherboard can be installed. In the shot below, you can see how many components could get in the way, negatively affecting the final build.

The hard drive cage, with its internal 3.5” bays, is first on our list. Thanks to our SSD and optional second 3.5” drive bay at the bottom, we can remove the entire cage.

After unscrewing just two screws, the drive cage is a thing of the past. This frees up a lot of room. Removing the adjacent 180 mm fan goes much the same way.

You actually need to remove the front panel in order to get rid of that 180 mm fan. Expect to use a couple of small screwdrivers and a lot of patience. While taking out the fan leaves a large hole, the air filter covers it pretty well.

Motherboard Installation

It’s finally time to install the motherboard. Or is it? As always, the I/O shield comes first. In this case, it needed an extra push or two to make it fit.

Now comes the hard part. The following installation steps need to be followed in precisely the right order. Let’s take a look at the motherboard with the cooler already installed. It’s oriented the same way that it’s supposed to be installed.

First, the 12 V CPU connector cable needs to be plugged into the upper part of the motherboard. Next, the front panel leads have to be attached, since the motherboard's connectors are somewhat covered by the cooler. The cables themselves aren’t very long, which makes it necessary to put the board in the chassis and tilt it backwards to access them. We used a 45-degree wedge made of wood and covered with foam rubber to keep the platform tilted up. You'll want to use something similar, or have someone ready to lend a hand for a few minutes.

Now it’s time to carefully lower the motherboard onto the spacers. The large cooler has a tendency to rip off the cables unless you hold onto them, making sure they stay put as you lower the board. These images illustrate what we're taking about pretty well.

It’s also a good idea to connect the SATA cables while the motherboard is still tilted. There’s enough space to install the 24-pin motherboard power connector, USB 3.0 connector, and HD Audio connector after the motherboard is installed.

And that’s it for the installation. Whew, it's finally all done!

Without a drive cage in there, the SilverStone case looks downright roomy. This allows enough chassis volume to cool the APU passively, though you still need to keep an eye on ambient temperatures. Summer weather without sufficient air conditioning can prove fatal for any passive system, no matter how large. Maintain a comfortable room temperature though, and you should be fine.

To protect the motherboard from the weight of its CPU cooler, SilverStone provides a holder that’s attached to the bottom of the case and can be adjusted to support the cooler.

    Great PC !, but if it was mine I would be scared... "no fan noise .. is it burning?"

    Great article! Much more DIY than the usual articles on Toms.
    Much appreciated.

    As someone that also uses a semi-passive PC (fan only turns on when needed), I'm disappointed that you guys left out a few big things:

    1. undervolting the CPU and GPU

    2. underclocking and farther undervolting the GPU for 2D mode

    3. hybrid cooling setup for GPUs where the fan only turns on at a high temperature (may require GPU BIOS editing depending on GPU model)

    OPTIONAL (due to risk): removal of CPU IHS

    I was disappointed there wasn't actual stress test temperature results of the APU for the passive cooling solution.

    But otherwise it's a neat article, personally I would sacrifice dead silence to use a cheaper HDD and perhaps more of those silent fans if I were to build one myself.

    no love for sapphire's passive ultimate HD 7770?

    Pentium G2120 + Sapphire Ultimate HD7750 would have been a better choice. And you can pay extra for a low-power Core i5 instead since it's not that expensive compared to the rest of this build.

    When i hear gaming from the TH I really expect to see something in the realm of 500$ SBM machine or at least something close. What I see here is realy nice office pc.

    The main issue is the GPU, and that would require a hybrid passive-active cooling solution much like was done for the CPU, but for some reason they didn't even try such a thing...

    I wonder about an i5 or i7 S or T model and crossfire 7750's. You might need a bigger case and a longer motherboard that allows gaps between cards.

    I don't like auto-start fans. They tend to turn off/on at weird times and become annoying...

    Silent PC (Gaming) is simple. Large passive water cooling such as the Zalman Resevator on the CPU and GPU, and anyother components needing heat dissipation. I've done this for the last 8 years, not for the silence, but because it's nice to see the temp never stray from 40-45, and never worry about cooling again.

    It has a fan. A FAN. It isn't zero dB.

    I'm a fan! (and I make a LOT of noise) :D

    By the way, I own two of those Samsung Blu-Ray drives and the blue LED in the button is overly bright. I would NOT want to set that case on my desk.

    One more thing. I like bottom mounted power supplies because I like a low center of gravity on my builds. However, I prefer the top mounted PCI slots. The video cards not only look better with their coolers on top, but the heat rises off the video card and into the video card cooler making it more effective, especially in a build without air movement.

    pity they put the bluray in it would be much louder than most actively cooled cases anyway

    1. undervolting the CPU and GPU
    This is always possible but each CPU/APU and GPU is a unique piece. Undervolting 10 APUs can can give you 10 different results. If it works with higher voltage it works also with undervolting. But I must check the worst case and only 100% stable settings. :)

    They failed to mention how loud it was when both the fan and blu-ray drive had spun up
