Heat increases thermal noise. Thermal noise is audible as hissing in analog circuits. It also contributes to jitter in digital circuits. It also decreases the life of electronic components.
The reason radio astronomers use cryogenically cooled amplifiers in their antenna systems is to minimize the thermal noise to effectively improve the S/N ratio of their receivers. The circuits they use use semiconductors that are designed and built to work at cryogenic temperatures. If you cool a "normal" transistor to cryogenic temperatures it will probably stop working until it warms up again (assuming it doesn't get destroyed by the cooling/rewarming processes).
