As of November, 2009, I have purchased a new computer. It is silent. It can be seen at: http://aprivatebeach.com/blog/2009/11/custom-silent-pc-nov-2009
This is what my case looks like from the front. The top fan is an 80mm exhaust fan. I ran out of 120mm fans so it had to do. The bottom fan is a 120mm intake fan. Both fans are fastened using plastic zap straps. I also took off two face plates. This is to allow the hot air to leave the case. Apparently, without this fan, the inside of the computer gets quite hot.
It should be known that hot air rises and cold air stays low. Furthermore, hot air will not passively leave the case. You have to push it out.
Remember that air circulation is a must in any closed computer case. Cold air in and hot air out. If the inside has too much hot air, the computer will get noisy. I should know since it kept getting too noisy when I had only a CPU fan. I would open the case only to feel hot air coming out. I do not have that problem anymore. It is even quiet during the summer months.
As you can see I stuffed the extra cords from the power supply on top of the DVD burner. Kinda messy but it works.
Another screenshot of the 120mm intake fan on the bottom. There was mesh on the front, but I busted it off to allow more air flow.
This is the Zalman 460W, 120mm bottom intake fan power supply. The giant piece of metal below it is the heatsink on my CPU. This is the Andy Samurai Master CPU heatsink.
This is the power supply and the CPU heatsink with the fan installed. The 120mm fan on the back is attached to a blue 120mm to 80mm fan adapter holder. It is an intake fan. Again the rear intake fan is held in using twist ties. I cut a hole in the back to allow more air to flow into the case. Because the power supply is taking air from inside the case, I had to push cold air into the case from the back just below the power supply. If the power supply is sucking in hot air, the 120mm power supply fan will spin faster and get noisier.
This picture is kinda blury, but it is a 120mm fan attached to a PCI expansion card. The card has the connectors to the motherboard sawed off and a square hole cut into it. I attached the fan onto the PCI card using plastic zap straps. The video card fan which is about 20mm in diameter was disconnected and no longer working. This was the fan that was making all the noise. This 120mm fan blows air onto the video card.
This is another picture of the graphics card fan on a cut-up PCI card blowing air onto the graphics card above it.
A blurry picture of the 120mm intake fan on the back of the case. This is screwed onto a 80mm section by using an 120mm to 80mm adapter. Without the adapter, a 120mm fan would not fit.
This is a picture of the 120mm intake fan twist tied to the bottom front of the case.
Here is the complete picture. It is quite a mess. You may notice that I had to use all sorts of different supplies to make this. I used standard screws to hold the 120mm to 80mm adapter, the blue plastic thing, in place. The screws were a bit long, but it works.
Listing of parts from bottom to top:
- 120mm intake fan
- 120mm graphics card cooling fan
- CPU heatsink and 120mm cooling fan
- 120mm intake fan on blue plastic 80mm to 120mm adapter
- Power supply with 120mm bottom intake fan
- 80mm exhaust fan installed above the DVD burner

If you need a cheap, silent replacement video card fan, but you do not want to replace the existing one or make your own. You can get one of these. http://forums.majorgeeks.com/showthread.php?t=143455. This forum is talking about the PCI slot 80 mm fan, http://www.newegg.com/Product/Product.aspx?Item=N82E16811999154. If you decide to use one of these, I recommend disconnecting the existing graphics card fan. I do not see much use of having a noisy tiny fan running with the 80 mm quieter fan.
The Scythe “Kama Stay” multi purpose solution, although a little more expensive, can house a 120mm fan in a PCI slot. Furthermore, the fan can be taken out and replaced. It has other uses too. http://www.scythe-usa.com/product/acc/071/sckst1000_detail.html

If I got the Centurion 590 computer case which is about $80 Canadian, I could have easily fit these large fans in without all the ties. Furthermore, I could get by with one less fan. Unfortunately, I got the standard generic computer case. I had to make it work.
Many of you may think that I am a power computer user. I use this beast to play all the latest games and such. You are all wrong. This is not a power computer. This is a silent computer. Specifically designed to be inexpensive, efficient, easy and cheap to repair and silent. I chose the cheapest CPU heatsink that I could find that would hold a 120mm fan.
The graphics card was a mistake. I should have done some research and gotten a fanless or a graphics card where the heatsink could be replaced with a larger one. The stock fan on the graphics card was so noisy, I was getting a headache. Previous older video cards had no fan, so I never had a problem before.
If this computer breaks down, I will often reuse parts that are still functional on the new computer. The video card, 56K fax/modem, DVD drive, fans, etc. I bought a new one for this one because the old video card was six years old. I thought it was time to get another.
As of November 2, 2009, I have received my new computer. The computer can be seen at . Since it has 120mm intake and outtake fan slots, no modifications and/or zap straps have been used. custom-silent-pc-nov-2009
As of September 20, 2010, I have converted the above to a negative air pressure computer. The changes made are:
- I have removed the bottom intake fan.
- I have turned the back intake fan into an exhaust fan
Therefore, the air is being pushed out by the back exhaust, top power supply, and the top front exhaust. Gets real dirty, but hopefully, it works better.
