If you want great performance at a few decibels then take a look at the Titan Amanda TEC Cooler .
They both are thermoelectric coolers that can install right out of the box, no measuring or planning of loops are required. Therefore the ease of installation of air cooling and better-than-water-cooling performance.
i lvoe the tuniq tower 120, however there are some mobos that reject it because of metal or something, u need electromagentic tape or something?, like the biostar tforce 965pt
