5 Myths About Liquid Cooling You Shouldn't Believe
In recent years, Intel and AMD have released many high-heat processors that are hard to cool with air tower coolers. Only liquid cooling systems can handle them effectively. However, not all users prefer AIOs and their advantages. Some consider them unreliable, expensive, and difficult to install. But that’s far from the truth. Let's look at the most common myths about liquid cooling and explain why you shouldn't believe them.
Most Common Myths
Myth 1: AIOs often leak
When liquid cooling systems first hit the market, leaks were quite common. But those days are long gone. Manufacturers have identified and fixed weak points. Today’s AIOs often feature pressure release valves that provide extra protection against leaks. Even budget AIOs are now reliable and built to last.
Still, leaks can happen for three main reasons:
- factory defects;
- careless installation inside the case;
- cheap components used by some manufacturers.
Leaks due to factory defects are rare. More often, users accidentally damage their AIOs during installation. To avoid leaks, install your cooler carefully and never overtighten the tubing—it should hang loosely, not be stretched tight like cables.
Some users buy extremely cheap AIOs from unknown brands to save money. Unfortunately, such coolers often lack in quality and durability. To avoid problems, go with well-known brands like DeepCool, Thermaltake, Corsair, Lian Li, be quiet!, and others.
Myth 2: AIOs are very expensive
Yes, AIOs are more expensive than air coolers. But calling them overpriced isn't fair. Let’s take a look at DeepCool, one of the leading liquid cooling brands. As of March 2025, prices are:
- Dual-fan DeepCool LE520 – 70 – 90 $;
- Triple-fan DeepCool LE720 – 90 – 100 $.
These prices are comparable to premium air coolers. And feature-wise, these AIOs are not lacking at all. They include ARGB lighting and pressure release valves, just like high-end models.
Only flagship AIOs are truly expensive. They come with 420 mm radiators, pumps with LCD displays, and VRM cooling. Most users don’t need these features, so such models are typically bought by enthusiasts.
Myth 3: AIOs are hard to install
Air coolers include radiators, fans, screws, and brackets. Even beginners can install them easily. AIOs have a few more parts, so yes, installation is a bit more involved—but not much.
To install an AIO, you need to:
- attach a backplate to the motherboard;
- screw fans to the radiator;
- mount the radiator in the case;
- install the pump onto the CPU socket;
- connect the cables.
As you can see, installing an AIO isn’t much different from mounting a large air cooler. There are a few extra steps, but it’s not complicated.
Every AIO comes with detailed installation instructions. Plus, there are countless videos online showing how to do it properly. Just be careful—don’t overtighten the tubes or damage the pump.
Myth 4: AIOs need regular maintenance
Only custom loop systems require maintenance. These are designed and built manually, often very expensive and aimed at enthusiasts. Custom loop PCs look amazing and unique.
Store-bought AIOs are maintenance-free. They don’t require you to replace the cooling liquid. These systems are sealed and will last 5–7 years with no maintenance required.
Myth 5: AIOs are louder than air coolers
Because AIOs have more components, some believe they’re louder than air coolers. That’s not true. Noise levels mostly depend on the quality of parts and how well the system is tuned.
Modern AIOs come with fans on hydrodynamic or magnetic bearings. These fans are quiet even at high speeds. Many also include vibration dampeners for even lower noise levels.
To make an AIO run quietly, simply configure its fan curve in the BIOS. Any modern motherboard supports this. With proper settings, an AIO can be even quieter than an air cooler.
Air Cooler or AIO: Final Thoughts
The most common myths about liquid cooling are:
- AIOs often leak. Modern coolers are reliable and well-built. The leak-prone models of the past are long gone.
- AIOs are very expensive. Only flagship models are. Standard AIOs cost as much as high-end air coolers.
- AIOs are hard to install. Installation is only slightly more involved than installing a tower cooler.
- AIOs require regular maintenance. Only custom loops do. Store-bought AIOs are sealed and maintenance-free.
- AIOs are louder than air coolers. With proper BIOS tuning, AIOs can be quieter than tower coolers.
Liquid Cooling Systems in HYPERPC Computers
Liquid cooling systems in HYPERPC computers guarantee stability and maximum performance. Our AIOs easily cool the most high-end CPUs, while staying quiet and non-distracting—perfect for both gaming and professional use.
The myths about complicated installation, high prices, or frequent maintenance are outdated. Modern AIOs are affordable, reliable, and packed with quality.
