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

By Igor Wallossek

For many folks, the most beautiful sound that a PC can make is no sound at all. How close can Tom's Hardware get to a zero-decibel configuration and still lend up with a compact, functional machine capable of mainstream gaming, without breaking the bank?

Temperatures Under Full Load

Temperatures Under Full Load

The ambient temperature while we tested was 22 degrees Celcuis (72 degrees Farenheit). Using a general-purpose computing application helped us tax the platform completely. A gaming workload allowed us to shave 8 to 10 degrees Celsius from our worst-case readings.

Bottom Line So Far

Thermals shouldn't be a problem so long as your air conditioner is working in the middle of summer. But just in case, let's look at what it takes to install an almost-silent fan.

    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.

    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

    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.
