# [Psychip aka Noise Killer!](https://psychip.net/entry/psychip-aka-noise-killer) ## December 08, 2012 Im getting older. really pissed off that fan noises at last days. and today, spend up to 50$ and 4 hours for suppress this screaming machines. Result: almost zero db! **Development server** has four ide hdd and two unboxed power supply. also all pci card slots full. this means high energy consumption and high temperature. i modded it to an old i486 hardcase and drilled small holes for a stable air flow. also cpu cooled with two combined psu fan. most psu fans designed for humidity extraction. their noise almost unhearable. **Desktop pc** is easy part of operation. first tried Xigmatek [aio-s80dp](http://www.xigmatek.com/product.php?productid=23&type=photo) water cooler. looks like really high technology for a personal pc but i got two issues with this. first, it works great and creates a waterfall sound effect. like an aquarium. second, it was not fit my hardcase. yes first issue is a cover for this reason. i refunded it and purchased [durin d982](http://www.xigmatek.com/product.php?productid=3&type=photo)model of same brand. it uses constant thermal oil with copper tunnels. this is same technology in new era notebooks. whatever, currently im installed durin d982 and got 25~30C in 100% cpu usage. new personal record! Today, we defeated the noise.
