The Corsair H150i Pro is an exceptional offering. Not only is it the quietest closed-loop cooler I have tested to date, but it does so while offering top-tier cooling performance. Granted, part of its performance is due to its 360 mm radiator. With the extra surface area and a third fan, it manages to come within just a few degrees Celsius of the expandable offerings from EKWB and Swiftech. Not to mention that it does so while being quieter. Simply put, the only other closed-loop cooler that offers similar performance is the Fractal Design Celsius S36, which is a full 3 decibels louder.

As with most Asetek-based units, installation is easy with very little effort needed to get the H150i Pro installed. Add to that perfect clearance around not only the first expansion slot, but the DIMM slots as well. Build quality is good with no glaring issues or faults to speak of in terms of the CLC. Meanwhile, the ML series fans provide good airflow with little noise, which is due to the magnetic levitation bearings that create no noise I could discern. Add it all up and pair it with a solid five year warranty and you have a winner.

A few issues are apparent. First and foremost is the price. The Corsair Hydro Series H150i Pro has a massive price tag of $169.99. At that price, it is competing with expandable custom liquid coolers. Even with the high quality fans which make the Corsair offering a true premium option, the price is a hard pill to swallow. This is made worse by the Fractal Design Celsius S36 which comes in at $119.99; $50 cheaper for essentially the same performance. In the end, they trade blows depending on which features you prefer.

The pump also feels a bit light compared to other closed-loop coolers; Corsair seems to have worked some magic as the pump feels nearly weightless compared to the rest of the unit. The Asetek-built Celsius S36 pump feels a bit heavier while other products on the market weigh a ton in comparison. While that did not effect cooling performance or quality, the light weight did initially catch me off guard. However, considering the results, it becomes more of an oddity than an issue. The only other issue is that the Corsair Link software just feels a bit dated at this point, and very cluttered. It works fine, but the user interface could use an overhaul.

My only other thoughts come down to the price and what you get. Corsair is definitely going premium here. However, a major part of that high cost and premium feel is due to the ML series fans. It's not uncommon to see users replace the stock fans on a CLC cooler. In this case, Corsair has made sure you don't need to, which helps alleviate some of the sting in regards to its price in my eyes.

When it comes to all-in-one liquid coolers, those wanting RGB LEDs with top-tier performance and a quiet operation should take a good look at the Corsair Hydro Series H150i Pro.
