LN2cooleds

LN2cooleds is a term often used in online communities, particularly those focused on PC hardware and overclocking. It refers to the practice of using liquid nitrogen (LN2) to cool computer components, most commonly CPUs and GPUs, to extremely low temperatures. This is distinct from typical liquid cooling systems, which use a water-based coolant.

The primary goal of using LN2 is to achieve significantly higher clock speeds than would be possible at ambient or standard liquid cooling temperatures. By drastically reducing the operating temperature of a processor or graphics card, the electrical resistance within the silicon decreases. This allows the component to handle more voltage and operate at much higher frequencies without experiencing thermal throttling or damage.

LN2 is typically stored in a dewar, a specialized vacuum-insulated container. During the cooling process, the LN2 is poured directly onto the component, often with the use of an insulating "pot" to contain the extreme cold and prevent condensation. The extremely low temperature of LN2, around -196 degrees Celsius (-320.8 degrees Fahrenheit), allows for substantial overclocking.

However, this method is highly experimental and carries significant risks. Extreme cold can cause materials to become brittle, leading to physical damage. Condensation is a major concern, as moisture can cause short circuits and destroy components. LN2 cooling is generally reserved for competitive overclocking events or for enthusiasts seeking to push hardware to its absolute limits for short periods. It is not a practical solution for everyday computer use due to the cost, logistical challenges, and inherent risks involved.
