Cooling air temperature can be improved with these guidelines: Supply cool air to the hot components as directly as possible. Examples are air snorkels and tunnels that feed outside air directly and exclusively to the CPU or GPU cooler. For example, the BTX case design prescribes a CPU air tunnel. Expel warm air as directly as possible.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
An active laptop cooler. A laptop/notebook cooler, cooling pad, cooler pad or chill mat is an accessory for laptop computers intended to reduce their operating temperature when the laptop is unable to sufficiently cool itself. Laptop coolers are intended to protect both the laptop from overheating and the user from suffering heat related ...
Although the pin-fin has 194 cm 2 surface area while the straight-fin has 58 cm 2, the temperature difference between the heat-sink base and the ambient air for the pin fin is 50 °C, but for the straight-fin it was 44 °C, or 6 °C better than the pin fin. Pin fin heat sink performance is significantly better than straight fins when used in ...
Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero. Many engineering fields in the US, notably high-tech and US federal specifications (civil and military), also use the Kelvin and ...
Cooler weather can dampen the immune system, which makes our bodies more susceptible to infection. The body is generally good at responding to drops in temperature, but the nose and upper ...
The Energy Department says that even turning thermostats back 7 to 10 degrees from their normal settings for eight hours a day can save as much as 10% a year on homeowners' heating and cooling ...
