QuietPC has enhanced its product line with the introduction of some of the quietest fans currently on the market. The AcoustiFan Noiseless & DustPROOF 80mm Fans work as advertised and provide low noise levels for those consumers looking to silence their PC's. The bundled accessories and add-ons are a plus and very easy to install whether your case chassis consists of a desktop or full tower case. Add in the extra screws, silicone gel grommets, and fan gasket and you have a well rounded package. I am a little skeptical on the DustPROOF concept and can only speculate that this can only be judged over a period of time. While the AcoustiFan Noiseless & DustPROOF 80mm Fans do have positive attributes there are some negative points worth mentioning. While I applaud the inclusion of the 3-pin to 4-pin fan adapter for lowering fan speeds the default configuration is quite messy. Once installed, consumers will have to power down their systems, open the side case panel and manually re-configure the fan for noise reduction. As previously mentioned, there is a big trade off for noise reduction in the fact that these fans move less air than rival fans currently on the market. By far the biggest negative aspect of this product is the current retail price of $33 (CAN) / $28 (U.S). The high price point will no doubt deter the average consumer from purchasing these fans since you can pick-up a simple fan controller for the same price. To be fair the AcoustiFan Noiseless & DustPROOF 80mm Fans have been priced to compete against the SilenX brand which currently has gained some level of popularity. Overall, I'm rating the AcoustiFan Noiseless & DustPROOF 80mm Fans a final score of 7 out of 10.
