Best HP Liquid-Cooled Gaming PCs

Tulie Finley-Moise
You never really think about that constant low hum emitting from your desktop tower until you load up one of your favorite RPGs and things go a little haywire. Every computer, no matter how big or small, generates heat during operation. Within that mechanical frame, all of the high-powered internal processing you depend on for seamless performance requires a considerable amount of electricity.
Heat output is a direct result of the sheer amount of electricity that pumps through your computer’s wiring and circuitry. The central processing unit (CPU), graphics processing unit (GPU), hard disk drive (HDD), and optical disc drive (ODD) generate the most heat within a desktop tower.
Integrated air cooling fans are responsible for tempering your system and protecting your PC from overheating. But the bigger and more powerful your system, the stronger your cooling system needs to be. Enter liquid-cooled PCs.
Gaming computers are typically equipped with high-end CPUs, GPUs, HDDs, and ODDs which allow for complex program functionality, but they also generate more heat than a non-gaming PC. In order to properly accommodate the heightened heat output, many of HP’s gaming computers feature liquid cooling systems. A unique alternative to standard fan cooling, liquid cooling changes the scope of gaming PCs.
So, what’s the scoop on liquid-cooled gaming computers? What are the advantages over air-cooled PCs? What are the best HP liquid-cooled gaming PCs, and is adding liquid cooling to an air-cooled gaming PC possible? Let’s take a deep dive into these burning questions.

Liquid cooling vs air cooling: Which is better?

Case fans are the finishing touch to any PC. Working overtime to prevent any nasty overheating, these integral coolers keep things safe and sound within your computer body. Air cooling is the standard for computer cooling systems. That low stirring hum you hear when firing up your favorite game or a newly downloaded photo manipulator is the sweet sound of your air cooling at work.


Air-cooled PCs are the epitome of low-maintenance performance. They require little-to-no upkeep outside of the occasional dusting. The standard PC comes with an assemblage of pre-installed case fans capable of sufficiently cooling your CPU, GPU, and HDD. No extra work or added features necessary.
Air-cooled PCs tend to come with smaller price tags than their liquid cooled siblings. So as long as you’re buying a quality computer, you can expect to get top-quality integrated cooling systems too.
For gamers, the downside to air-cooling is that programs heavy on the CPU, GPU, and RAM will likely send your PC into overdrive, generating more heat than it may be able to handle. This generally results in overheating, loud fan spinning, crashing, powering off, or screen tearing. So for you over-clocked gamers with beefed up rigs, air-cooling may pose more of a threat to your game than it does an advantage.

Liquid cooling

Liquid cooling systems are typically found in higher-end gaming computers made for over-clocking, power-processing, and grandiose graphics. Though they may seem more complex by their unique nature, they offer far higher levels of efficiency than their fan-based counterparts.
While it may seem risky to have a water system installed so close to computer hardware, water actually transfers heat more efficiently than air. This means liquid-cooled computers consistently operate at cooler temperatures.
With this consistency, you can say goodbye to random spurts of noisy fan action. Liquid-cooled PCs are quieter, effectively reducing the noise level to zero even as you load up your most intricate game scapes. Even though most liquid-cooled PCs include an integrated case fan, the fan will operate at such a low RPM you’ll likely never notice it.
Gaming is all about efficiency, so if you’re interested in amplifying your rig’s true grit, a liquid-cooled PC is the way to go. Liquid cooling keeps up with the times, allowing you to challenge your rig to handle the latest GPUs and CPUs without ever worrying about overheating.
