Junction temperature, short for transistor junction temperature, [1] is the highest operating temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior. The difference is equal to the amount of heat transferred from the junction to case multiplied ...
Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
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 ...
The additional heat increases the ambient air temperature within the system case, which may affect other components. The hot air blown out of the case heats the room it's in. Fan noise: High-performance fans running at maximum speed used for the required degree of cooling of an overclocked machine can be noisy, some producing 50 dB or more of ...
A room-temperature superconductor is a hypothetical material capable of displaying superconductivity above 0 °C (273 K; 32 °F), operating temperatures which are commonly encountered in everyday settings. As of 2023, the material with the highest accepted superconducting temperature was highly pressurized lanthanum decahydride, whose ...
The motherboard (microATX) is in a horizontal position at the top, and the peripheral connectors go at the panel located at the rear of the case and USB ports at the top. The fans are also at the rear and front. The power supply is on the bottom rear. A computer case, also known as a computer chassis, is the enclosure that contains most of the ...
High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at intermediate intervals.
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 ...
