In the IBM PC compatible market, the computer's power supply unit (PSU) almost always uses an exhaust fan to expel warm air from the PSU. Active cooling on CPUs started to appear on the Intel 80486 , and by 1997 was standard on all desktop processors. [ 2 ]
A fan controller with LEDs indicating fan status and potentiometers and switches to control fan speeds. Another method, popular with PC hardware enthusiasts, is the manual fan speed controller. They can be mounted in an expansion slot or a 5.25" or 3.5" drive bay or come built into a computer's case. Using switches or knobs, attached fans can ...
Poorly designed coolers may use fans which draw more current than allowed by the USB standard. Without correct protection, such devices can cause damage to the USB power supply. Inside the laptop, the USB power-supply has to output an additional amount of watts for the USB-powered fan, thus generating a small amount of additional heat.
Fans are used when natural convection is insufficient to remove heat. Fans may be fitted to the computer case or attached to CPUs, GPUs, chipsets, power supply units (PSUs), hard drives, or as cards plugged into an expansion slot. Common fan sizes include 40, 60, 80, 92, 120, and 140 mm. 200, 230, 250 and 300 mm fans are sometimes used in high ...
Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
A Thermally Advantaged Chassis (TAC) is a computer enclosure that complies with the Thermally Advantaged Chassis specifications created by Intel.It is capable of maintaining an internal ambient temperature below 38 degrees Celsius when functioning with Intel's Pentium 4 and Celeron D processors based on 90 nm process technology, and an ambient temperature below 39 degrees Celsius when using a ...
