A fanless CPU cooler based on heat pipe technology. A quiet, silent or fanless PC is a personal computer that makes very little or no noise.Common uses for quiet PCs include video editing, sound mixing and home theater PCs, but noise reduction techniques can also be used to greatly reduce the noise from servers.
Full-tower computer cases may contain multiple cooling fans. At the top of the case is a fan controller. Fan control is the management of the rotational speed of an electric fan. In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they ...
The type of bearing used in a fan can affect its performance and noise. Most computer fans use one of the following bearing types: Sleeve bearings use two surfaces lubricated with oil or grease as a friction contact. They often use porous sintered sleeves to be self-lubricating, requiring only infrequent maintenance or replacement.

The +12 V supply was used for computer fan motors, disk drive motors and serial interfaces (which also used the −12 V supply). A further use of the 12 V came with the sound cards, using linear chip audio power amplifiers, sometimes filtered by a 9 V linear regulator on the card to cut the noise of the motors.
