Do Water Cooling PC Need Refill?


Whether you use water cooling on your PC, it is possible that it is time for you to refill the system. There are a few steps that you need to follow to ensure that the system is running at optimal levels. During this process, you’ll need to add a biocide, clean the water block, and check for air pockets and vapor lock.


Choosing the right pump for your PC water cooling system is an important decision. While there are many options available, the pump you choose will affect the performance and operation of your water cooling system. It’s essential to understand how pumps work so you can find the best one for your needs.

A reliable pump will need to be strong enough to maintain adequate flow through components. If your pump is not performing properly, it can cause damage to your hardware. You should also be aware of the noise that your pump makes. It’s better to opt for a quieter model than one that makes a lot of noise.

Vapor lock

Several years ago, vapor lock was a common problem with carbureted vehicles. This was a problem because the liquid fuel that was being delivered to the engine would boil inside the carburetor. The vaporized fuel caused a back pressure in the fuel line, which meant that gas could not get to the engine.

Now, vapor lock is a rare occurrence with modern fuel injection systems. This is because the vaporization of fuel isn’t as likely to happen in an environment that is under pressure. The low boiling point of some fuel blends is also a contributing factor.

While vapor lock is still an issue, there are a few things you can do to help. First, insulating the fuel line is a good way to prevent fuel vaporization. Second, installing a heat shield on the engine will divert the heat away from the fuel line.

Air pockets

Putting together a PC water cooling system that works will take a little research and elbow grease. While you are at it, consider adding some thermal compound to your CPU. This will help prevent the CPU from overheating and possibly exploding. You may also want to look into additives such as anti-freeze to prevent freezing.

While you are at it, do not forget to check out your motherboard box. This is where you will find the various components that make up your PC. You will want to keep these parts in an anti-static bag to avoid damage from static. You may also want to consider a modular power supply as this will make disconnecting the various cables a snap.


Having built a few SFF systems, I’ve been able to appreciate the challenges associated with this small form factor. Besides being a tad twitchy, the components in your PC can be a little wet and a bit tricky to disconnect. This is where a little extra time and care goes a long way. Aside from water cooling, I’ve also found it useful to have the right tools at hand. This includes a multimeter and an assortment of pliers. The best part is that I’ve been able to avoid the dreaded ‘oops’ and get the most out of my system.

It’s not hard to see why SFF systems have gotten a lot more popular over the past few years. This is especially true if you are building an HTPC. Aside from the aforementioned limitations, you’ll need to deal with the aforementioned water cooling, which means you’ll have to take some serious measures to keep your components in pristine condition.

Clean the water block

Whether you’ve had a water cooling PC for years or you’ve just installed it, cleaning the water block is always a good idea. It can keep your system running smoothly for years.

First, you’ll want to make sure you have a clean work area. This is particularly important if you are going to disassemble the water block for cleaning. You’ll also need access to distilled water. If you don’t have distilled water, you can use tap water instead.

Next, you’ll need to gather some tools. You’ll need a flashlight, a pair of Phillips and flat screwdrivers, and a paper towel. You’ll also need a small container to store your small parts during the cleaning process.

Add biocide

Adding biocide to a water cooling PC is a great way to combat corrosion. The additive isn’t cheap but will keep your PC’s components protected for many years.

Distilled water is best for water cooling. Its low conductivity will reduce the likelihood of short circuits. Its impurities will be removed during the distillation process, leaving you with a clean water to cool your PC.

There are several products to choose from. Some companies offer premixed formulas while others offer a custom solution that will work best for your particular machine. For example, TITAN RIG offers PC coolant additives from some of the most trusted names in the industry.
