Liquid Cooling FAQs

When we introduced the CryoVenom R9 290 liquid cooled graphics card, VisionTek made liquid cooling nearly Plug and Play, which was great for more experienced PC enthusiasts. However, there are some PC DIYers who are new to liquid cooling, who may want to upgrade their PC, but not know how. This section explains the basics of liquid cooling, and the benefits of making the change.
A water cooled PC system works a lot like the cooling system of a car. Both systems take advantage of the basic principle of thermodynamics: heat moves from warmer objects to cooler ones. In a PC, the sole purpose of the system is to transfer heat away from critical computer components as quickly and effectively as possible, and to dissipate that heat through the system’s radiators.    A typical PC liquid cooling loop consists of the following components: A water block. The so-called “cold head” absorbs heat from the microprocessor. Liquid flows through the water block and over micro fins inside the unit. The micro fins boost the surface volume and allow for optimal heat transfer to the liquid that flows through the water block. As liquid flows through the unit, it absorbs the heat and moves it out of the component. A radiator. Equipped with one or more cooling fans, the radiator cools the heated liquid that runs through it and exhausts absorbed heat from the PC case, cooling the heated liquid that runs through it in the process. The larger the radiator, the more effective the cooling process is, and a lower liquid temperature can be achieved. A reservoir. A liquid reservoir holds additional liquid and helps the system stay free of air. A water pump. The water pump provides circulation for the coolant, allowing for more effective heat transfer throughout the entire loop. Without a water pump, the heat transfer does not work because the liquid coolant will not flow throughout the... Read more
When set up correctly, a liquid cooled system does not require substantially more maintenance than a traditional air cooled system. However, a PC user does need to regularly check the system to make sure the liquid level is optimal and that the coolant is clean. It is recommended that coolant in a liquid cooled PC is changed every 12 months. This will ensure that the system is clean. Additionally, regular checking that all seals are still water tight and that your tubing is free of cracks or discolorations is... Read more
In addition to low noise levels and overall cooler temperatures, a liquid cooled system can often be overclocked, boosting a PCs performance. The majority of today’s graphics cards and CPUs can be overclocked, but often have an underclocking or throttling function that keeps the component running at optimal performance levels. By liquid cooling these components, the hardware is able to constantly run at the highest performance levels, resulting in unmatched performance.    The key benefits of a liquid cooled PC are: Unparalleled cooling performance. Increased lifespan of components. Great overclocking potential. Silent operation. Improved computing power per cubic unit due to slim design (stacking... Read more
Modern age CPU microprocessors are creating twice as much heat as they were five years ago, and this is even more true for modern GPU microprocessors. Today, the most powerful dual-processor graphics card can generate as much as 380 watts of heat.    Many modern high-performance gaming PCs and workstations use multiple processors and graphics cards to ensure the best possible experience and workflow, but efficient cooling can be a problem. Removing such a high amount of heat in a small environment like a computer chassis is traditionally done at the cost of uncomfortably high noise levels.    Liquid cooling (also known as water cooling) is the best solution for rapid heat removal. It is the only solution that allows for successful heat removal from critical PC components with the lowest sound levels possible. Water blocks also offer lower profile cooling solutions than fans or heatsinks, which means PC users can get double the compute power in the same cubic footprint. Additionally, liquid cooled components have drastically lower operational temperatures than their air cooled counterparts, which increases the overclocking potential of these... Read more
