The Best Liquid CPU Coolers [July 2019]

Everyone who has either owned or operated a computer at some point in their lives is familiar with CPU heat. Whether you’re working with your laptop on your lap and begin to feel that unmissable heat emirate from the bottom of the machine onto your legs, or you’re using a desktop in an already-warm room and feel the temperature rise with every click, computers getting hot is just a fact of life. 

This is especially the case for those of us who work with pro-level applications and tasks—such as video editing, music production, or even gaming. 

And if you’re constantly pushing your CPU to its limits, the repercussions can be more serious than a warm leg or a slightly heated room. Constant amounts of extreme processing that overheat your CPU to the point that your internal fan can’t help can permanently damage your processor and subsequently your computer. 

Indeed, there have been several cases of both the CPU and surrounding circuitry melting away after prolonged periods of insufficient cooling, which can both ruin your work and lead to an expensive replacement board. 

It’s for this reason that more and more people are turning to external cooling systems to keep their CPUs nice and happy even during their more extreme tasks. These systems not only prevent dangerous and damaging overheating, they also actually enhance the performance of the processor itself. 

And although it may seem a bit counterintuitive, the latest and greatest CPU cooling technology is liquid-based—allowing for more efficient cooling across the board for people who are constantly pushing their processors to their limits. 

So if you find yourself constantly fretting about an over-pushed and super-hot CPU, we highly recommend picking up one of these liquid cooling systems before it’s too late. 

01 Corsair HYDRO Series H150i

Corsair HYDRO Series H150i

The most important element of any external CPU cooling system is safety. Not necessarily your safety as a user, but the safety of your processor. After all, what good is protecting a processor that becomes flooded with liquid and ends up crashing your entire system as a result? 

That’s why our number-one pick offers a series of safeguards and failsafes that will let you sleep easy at night knowing that your processor is constantly in good hands, even when it’s being pressed to its maximum abilities. 

This unit comes loaded with a fully customizable RGB backlit pump that provides vivid lighting effects to match your build, and you’ll be able to focus on your work while it does its work thanks to dual low-noise 140mm ML magnetic levitation fans that deliver incredible airflow and stunningly low noise levels (only around 20db at full-effect).

The software that powers this system is incredibly powerful, and allows you to quickly and easily adjust everything from the lighting to the individual fan speeds and beyond. You’ll even be able to adjust the pump speed in real-time as you monitor the CPU and coolant temperatures. 

This unit also comes with a very useful Zero RPM mode, which allows you to stop all fan movement entirely at low temperatures—thus saving you a great deal of power and output.

And although we would never award our coveted number-one spot to a piece of gear based on aesthetics alone, we should point out that this cooling system is especially sleek and stylish, especially when it has its lights on in full force.
