The insulation of most wires is made of polyvinyl chloride. Despite the fact that polyvinyl chloride has a number of advantages, the cost, good electrical insulating properties, really hardens in immersion baths and that's why :

During operation in an immersion installation, the cable is permanently insulated at a temperature of up to 45-50 degrees.The glass transition temperature of polyvinyl chloride is 75 degrees, but by analogy with freezing, the process begins earlier.Is it scary :Most immersion fluids for single-phase cooling are made on the basis of hydrocarbons.Polyvinyl chloride dissolves incyclohexanon, tetrahydrofuran, dimethylformamide, dichloroethane, little bit in benzene, acetone(swells). It does not dissolve in water, alcohols, hydrocarbons (including gasoline and kerosene). Most immersion fluids for single-phase cooling are made on the basis of hydrocarbons.That is, the insulation does not react with the liquid and does not lose its dielectric properties - the conclusion is not scary.

Modern electronic equipment uses chips made on the basis of silicon crystals. In fact, the chip is a digital integrated circuit, the active elements of which are transistors - while they all work in the mica mode - that is, either the transistor is open or closed. When overclocking, they have to perform their function faster, while switching large currents, which inevitably leads to an increase in energy consumption and heat dissipation. It is possible to consider such a process using the example of a copper conductor. There is a lot of information on the Internet about the cross-section of a conductor for transmitting a current of one or another value. At the same time, the temperature of the conductor always appears next to it. That is, the lower the temperature, the smaller the cross-section can be used (within reasonable limits of course) . It's about the same here. Provided that the appropriate amount of heat is removed, if the temperature of the chip is within acceptable limits, the chips can be safely overclocked. To what extent ? And what happens if I can take away the heat as much as I want? Any chip has a limit. An attempt to overclock above this limit will lead to irreversible degradation of the chip. This can be compared to stretching a spring, at some point it will simply deform and take a new shape, or break.And where is this limit?Modern equipment has a "safe overclocking margin" of 2 times as a rule.And how to understand that "it's enough"? In the process of overclocking, chip consumption grows almost linearly, but at some point it starts to grow sharply. It is possible to accelerate safely only within the linear section.
