A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink ; such a fan is also called a blower , blower fan , or squirrel-cage fan (because it looks like a hamster ...
Fans are used to move air through the computer case. The components inside the case cannot dissipate heat efficiently if the surrounding air is too hot. Case fans may be placed as intake fans , drawing cooler outside air in through the front or bottom of the chassis (where it may also be drawn over the internal hard drive racks), or exhaust ...
Centrifugal fans blow air at right angles to the intake of the fan and spin the air outwards to the outlet (by deflection and centrifugal force). The impeller rotates, causing air to enter the fan near the shaft and move perpendicularly from the shaft to the opening in the scroll-shaped fan casing.
The Ceiling Fan Direction for Winter First of all, it's important to know that the ceiling fan alone is not a suitable indoor heating system. In the winter months, make sure your ceiling fan ...
Since they must move more air through the same area of space, fans will become more noisy. Fans installed in a PC case can produce noise levels of up to 70 dB. Since fan noise increases with the fifth power of the fan rotation speed, [2] reducing revolutions per minute (RPM) by a small amount potentially means a large reduction in fan noise ...
How to adjust the direction of your ceiling fan in both summer and winter
Expel warm air as directly as possible. Examples are: Conventional PC power supplies blow the warm air out the back of the case. Many dual-slot graphics card designs blow the warm air through the cover of the adjacent slot. There are also some aftermarket coolers that do this. Some CPU cooling designs blow the warm air directly towards the back ...
In the case of the latter, it is done by using a fan blowing air into or onto the object one wants to cool. The addition of fins to a heat sink increases its total surface area, resulting in greater cooling effectiveness. There are two types of cooling pads that can be used for air cooling: one is the honeycomb design and another one is excelsior.
