=== Thermal management ===
{{Main|Thermal management of electronic devices and systems}}
[[Heat]] generated by electronic circuitry must be dissipated to prevent immediate failure and improve long term reliability. [[Heat dissipation]] is mostly achieved by passive conduction/convection. Means to achieve greater dissipation include [[heat sink]]s and [[Mechanical fan|fans]] for air cooling, and other forms of [[computer cooling]] such as [[water cooling]]. These techniques use [[convection]], [[Heat conduction|conduction]], and [[radiation]] of [[heat energy]].

=== Noise ===
{{Main|Electronic noise}}
Electronic noise is defined<ref>''IEEE Dictionary of Electrical and Electronics Terms'' {{ISBN|978-0471428060}}</ref> as unwanted disturbances superposed on a useful signal that tend to obscure its information content. Noise is not the same as signal distortion caused by a circuit. Noise is associated with all electronic circuits. Noise may be electromagnetically or thermally generated, which can be decreased by lowering the [[operating temperature]] of the circuit. Other types of noise, such as [[shot noise]] cannot be removed as they are due to limitations in physical properties.
