Jinak co oni pisou:

In my opinion I can see no reason why everyone that owns a Thermaltake Volcano 7, 9 or 11 doesn't buy of these. For the price you can't beat the performance and the ease of installation. One other noted feature of this product is the reduction of the noise the fan on the Volcano 7 makes. By reducing the back-flow air pressure from the fan; the fan noise must be reduced by a minimum of 7 to 10 db.
