Fan Listening Room. Notes: 8. Papst 60mm is sold only with the MCX(C)370-0A. 11. Thermaltake 60mm (TT6025-A) was previously named Volcano II 60mm (F126025BH). At the time of our initial testing, this fan was only available with the heat sink. Test shown reflects fan recording while attached to the heat sink. We believe this accounts for some additional noise/turbulence. 18. The Specifications of the Sunon 80mm high speed have changed slightly since the publishing of the Listening Room.
The new specifications are 39.5 CFM, 33 dBA and 3000 RPM. 21. The loudness of audio is commonly measured in decibel units (dB), and it is even sometimes measured in units such as Pascals, microbars, or dynes/cm2. In general, a decibel is a unit for expressing the ratio of the magnitudes of two electric voltages or currents. How does this apply to the sounds we hear? Another way sound’s intensity can be measured is in the voltage output of our audio equipment, also in decibels.

A modern harddisk is not that different, mechanically, from the first generation of harddisks that debuted with the IBM PC in the ‘80s. Today’s harddisks are also mechanical parts that use spinning platters and read/write heads to store or read information from them.
That also explains why harddisks haven’t seen the rapid pace of innovation as for example CPUs have; simply because the mechanics are holding the harddisk back from making similar leaps in performance. But to be honest that’s not entirely accurate, modern harddisks could be substantially faster, but not without either driving up the price significantly or introducing unwanted side effects. One of these side effects is excessive noise; because a harddisk has a number of spinning and moving parts it is virtually impossible to make a harddisk noiseless. Naturally we could counter the noise production by adding sound insulation. BlackMaxPC. Hard Drive Upgrade Guide. DiskOnKey. Motherboard Service. Legion Hardware. Back-UPS ES. Product Prices.
