Silent computer
07 May 2010

Since my first pc a 486dx2 50 I have been more or less allergic to noisy computers. The noise in the 486 was easy fixed, placing a long pencil in the PSU and the all the sound was gone. After that I had a couple of other computers sounding more or less, but I didn't do anything to stop the noise. But for the last 5 years I have been experimenting with a couple of different solutions. Mostly based on silent fans and silent computer based cases. But these solutions has all been failures, at least to my sensitive ears.

My current 2 years old rig is pretty silent, but not enough. I can still hear the fans and the hard drive. Here are some pictures from the building of that computer.

So now I feel it's time again for a new computer. This is the computer I should have build two years ago. I was looking into it, but did choose to spend the money on high end computer parts instead of an expansive passive cooled case. This time I will spend the money on both high end computer parts and a passive cooled case. =)

Some gfx cards I did also look at. The is a good source to get a quick performance comparison between different cards. The numbers below is a passmark G3D rating.

Hard drive

It's said in different reviews that the intel X25-M is the fastest SSD disk, but it's more expansive and wasn't available in any of the webshops at the time I did order the computer parts.
