Computer Water Cooling Reservoir
The vast majority of people who use a computer will never have any need for a computer water cooling reservoir. Indeed, it's only a tiny minority of people who will actually understand what it does and why there might be a need for it.
If you are one of the small number of people who want to operate a water cooling system for your computer, it might well be that you need a replacement reservoir; for instance if your original one has become damaged or broken. Or maybe you're simply shopping around for the different components that make up the overall cooling system.
There are several well known brands of computer water cooling equipment , as well as unbranded and generic varieties that you can choose from.
About computer water cooling systems
The origin of the idea for cooling your computer with a water cooling system dates back to the time when computer processor chips were prone to getting extremely hot. This compromised the performance of the computer itself and usually required a lot of fan spinning within the machine to try and cool down the overheating chip.
With a fan whirring away at high speed, the computer would become quite noisy. On top of this, there was no guarantee that this air cooling method would actually work effectively for cooling down the processor in the first place.
So the idea of featuring separate water cooling systems was born, enabling you to cool down your computer's processing chip more effectively and efficiently than with the traditional in-built fan.
One of the components of a computer water cooling system is the reservoir that stores the water. Essentially, this is a receptacle that you top up with distilled water, in order for the mechanism to go into action, cooling down the water and providing cold air to keep your computer operating at a lower temperature than without the cooling aid.
