Build a Silent PC with our guide

I have written much advice on what to do to build a quiet computer. Here is what NOT to do!

Hopefully, you've been following the advice I've been writing about here at If you have, You will likely have a computer that runs so quiet, you won't be able to tell if it on or not without looking at it.

You may be wondering about some other techniques you've heard about, or daydreamed on your own, and why I haven't suggested them.

In this article, I am going to tell you what not to do in order to build a silent PC.

Don't #1: Do NOT run a PC without proper airflow. The obvious source of most of the noise in PC's are fans, but that does NOT mean you should simply turn them all off! Your computer NEEDS adequate airflow, and without it, you are going to run into severe stability problems.

Solution: Take a look at some of the silent case fans we have listed on our Silent PC Cases and Silent Case Fans Page. Coupled with a fan speed controller (rheobus), you will be able to attain adequate air flow and cooling, without suffering from a loud PC.

Don't #2: Do NOT use loads of sound dampening material in your PC. You've likely seen these products around; studio-like sound dampening foam, precut to sizes that will fit inside your case. This is NOT a good idea, because not only does the material insulate sound, but it also insulates heat. Your PC will essentially become an oven.

Solution: Try to eliminate the source of the noise, rather than smother it. If you follow our entire Silent PC Guide, you will have replaced pretty much every component that makes noise, so there should be no need to stuff your case with foam. What you need to do is find out what on your PC is making the noise that is bothering you, and find the relating page in our guide (see the jump menu below).

There may be some good sound dampening products out there; I just have yet to come across any that are reliable and affordable. Perhaps I'll look into it a bit more in the near future, and add an article to the site.

Don't #3: Don't cover your case! This is pretty much the first 2 Don'ts combined. I have also seen products that are basically enclosures FOR your case, that are build with sound dampening material. You know why this is a bad idea by now; you're blocking air flow AND you are insulating the heat from your PC.

Solution: Just avoid anything that blocks air flow and insulates heat!

Don't #4: Don't opt for TMD fans when looking for a quiet solution for your CPU cooler. One of the biggest things to hit the fan scene recently were CPU heatsinks that use TMD fans for cooling. According to the manufacturers, the use of TMD fans allows for more surface area of the fan to be used, allowing for silent operation. In my experience, these fans vibrate like you wouldn't believe, and in a silent PC, vibration is the last thing you want. Furthermore, they are hardly what I would call silent to begin with.

Solution: In most cases for CPU cooling, you want to go with a huge passive heatsink, and a big fan blowing over it. Check out Silent CPU Cooler Page for more info.

That's it for today! This page will be updated constantly, so keep an eye on us for more info! I am also going to start a Silent PC FAQ, so if you have any questions on that, contact me! Thanks! Jump Menu
