In short it's a high pitched squeal/whine/hiss/buzz noise emanating from a computer or electronic device. It can often be located towards a specific component such as a power supply or graphics card and the noise often changes volume and pitch especially when a certain task is carried out on a PC such as a. Common sense prevails here. You need to look and listen to locate the noise but it's not always an easy task as the culprit maybe difficult to get to or covered by a cooler. What you are looking for is usually a capacitor or inductor/power coil. Capacitors haven't. Capacitor squeal will almost certainly result in a failure if it already hasn't. It will be RMA time for this component. Coil whine is a different story but cannot always be solved, after all the acoustic noise is a by-product of something working normally; 1 – Leave it. There are actually 2 causes; Capacitor Squeal is actually the noise heard when a capacitor is about to fail. Essentially it's where gas is escaping.
[PDF Version]This is because a capacitor functions as the simplest noise filter by blocking DC current while allowing noise to pass. However, since there are many types of capacitors with different properties (frequency-impedance characteristics, etc.), if they are used in the wrong way, they can actually end up increasing noise.
Some ceramic capacitors can have a piezoelectric effect and start to make noise. Also, see this related question. If your computer is old enough it uses relays for its logic circuits. Thousands of relays switching at once makes a lot of noise!
Capacitors, in particular, store electric charges, but they also play a major role in noise reduction. As digital devices become smaller and handle higher frequencies, the low-ESL and low-ESR types of bypass capacitors and decoupling capacitors are becoming more prevalent. Noises have colors? Noises have colors?
When noise enters a DC current flowing inside an electronic circuit, voltage fluctuations could occur, leading to IC malfunctions. To deal with this, capacitors are widely used to remove noise. This is because a capacitor functions as the simplest noise filter by blocking DC current while allowing noise to pass.
Some applications can use electrolyte or tantalum-type capacitors, preferably thru-hole types when acoustic noise is problematic. But for applications that are more cost-sensitive or size-constrained (such as personal electronic devices), you cannot avoid thin, small ceramic capacitors, and the need to reduce noise immediately becomes critical.
Can electronic components of a computer (transistors, resistors, capacitors, ICs, screens, power supplies, etc.) also produce noise, or is noise limited to the realm of mechanics? Some ceramic capacitors can have a piezoelectric effect and start to make noise. Also, see this related question.
