About Air & CPU Liquid Cooling

What is Liquid Cooling?

Liquid Cooling: is a method of removing heat from computer components. Components such as the Central Processing Unit (CPU), graphics card and motherboard can all be liquid cooled. These particular components generate the most amount of heat in a typical computer. They are generally air cooled which is fine for general applications however, adding a liquid cooling unit can allow system fans to run at a lower speed which, in turn, reduces the noise. Heat is also removed more quickly via water.


HydraGaming PCs in Coffs Harbour highly recommend CPU liquid cooling as the benefits are many...and... in our opinion, we provide the best liquid cooling in Coffs Harbour. We make it easy, safe and only use the best brands!


Air Cooling vs Liquid Cooling

Air Cooling


Air Cooling is the most popular and widely used cooling method. Fans attached to heat sinks do a good job of keeping components cool inside a computer case. There are drawbacks that need to be kept in mind though.


Air Cooling is a lot louder than liquid cooling. To cool the same amount of heat as a liquid cooler an air cooler needs to have its fan running faster which generates more noise and typically blows hot air back onto other components in the system such as RAM.


Liquid Cooling


Liquid Cooling is usually found in gaming computers. Gaming computers have more demand put on them which means the harder they work the hotter they get. Multiple graphics cards can heat up a gaming rig considerably and that means air cooling will not be as effective.


All-In-One liquid coolers, like the ones HydraGaming PCs sell, consist of a loop of parts which take heat away from the hot component and disperses it into the air where it is cooled. 


It starts with the water block, the water block is usually made of copper or aluminum and it sits directly on top of the CPU or Graphical Processing Unit (GPU). It has channels grooved inside of it to slow the coolant down to allow it to soak up heat. As the heated coolant moves through these channels it is sent through a tube that is connected to the water block through to a radiator. The heated coolant flows through rows of pipes inside the radiator where fins allow the heat to disperse into the air with the help of slower spinning fans. Once the coolant is cool again it exits the radiator and flows back to the water block where a pump is located. Now the entire process starts again.


Which type of cooler is right for me?

In short?... it depends. You can decide for yourself with the advantages and disadvantages of both types of cooler below:


Air Cooling Advantages: 


- Great for computers that are not overclocked

- Larger diameter fans are slightly quieter than smaller ones.

- Cheap.  Fans are a lot cheaper than liquid cooling units

- Quiet fans are available


Air Cooling Disadvantages:


- Stock fans are loud

- Cooling performance is much less than liquid coolers

- Fans will blow the heat out of the heat sink back onto other components inside the PC case

- More fans are needed to cool the same amount of heat



Liquid Cooling Advantages:


- Better cooling performance over air cooling

- Heat is taken away from the source quickly

- Liquid coolers come in popular sizes that are compatible with most cases

- All-In-One units don't need priming or refilling

- installation is very easy

- Low evaporation hoses make sure the water stays inside for the life of the product

- High strength hoses prevent kinking and tearing 


Liquid Cooling Disadvantages:


- Not all cases are compatible with liquid coolers

- Liquid coolers are more expensive

- On some models pump noise can be heard 

- There's always the possibility of the cooler leaking but this is extremely rare with All-In-One units

- If your PC is situated in a closed room,  liquid coolers can actually increase the room temperature which can actually heat the PC up instead of cooling it properly. Good for winter but bad for summer!
