Corsair H100i PRO RGB Liquid AIO CPU Cooler Review

Corsair has just unveiled its new model Hydro AIO H100i CPU AIO cooler. These work with all new AMD and desktop Intel processors. Its new claim to fame is super quiet magnetic levitation fans. As usual, cooling our highly overclocked AMD Ryzen CPU is our focus, so how does it cool when pushed to the limit?

Package & Specs

The Pro series from Corsair is a premium product, and the packaging reflects that well. The cooler arrived in a very oversized outer box, but still in flawless condition. The printing on the box is some of the finest we have seen. The front of the box is bold and colorful, sporting a great image off the cooler itself, as well as highlighting the coolers primary features. Around back you get the tech specs as well as detailed information on the cooler as well as the ML Magnetic Levitation fans. Two of the sides go into detail about Corsair LINK software, as well as the contents.

Opening the box you are first greeted by the instruction manual and warranty paperwork set on top of a foam pad covering the contents. Under the pad we get our first look at the cooler and accessories nestled into a pressed fiberboard insert. Everything is bagged and the fans also come in thin cardboard sleeves and all components came in perfect condition.

    For a premium cooler the H100i PRO does not come with much in the box. You get the cooler itself, two ML magnetic levitation 120mm fans, mounting hardware for the supported sockets, and an internal USB 2.0 header to 90 degree USB Micro B cable.

    The thermal interface material is pre-applied to the baseplate, and appears to be of good quality, however it will not be being used during testing. We use Prolimatech PK-3 for all our AM4 testing so we do not introduce another variable. Corsair also provides enough screws to do a push/pull configuration if you choose to add an additional two fans.

    Fit and Finish

    The fit and finish on the H100i PRO is outstanding. The paint on the radiator, as well as the chrome Corsair logo look fantastic. The sleeving on the low permeation tubing is very tight, and silky to the touch. The wires coming from the pump head are not sleeved, however we feel this is a benefit, as making these more bulky would make it more difficult to hide these should you wish to keep your wiring neat and tidy.

    The finish on the baseplate is very well done with only feint machining marks present, and the screws are countersunk. The pump head itself has a high gloss plastic with an aluminum bead-blasted bezel around it. Care should be taken with the middle surface as this will be a fingerprint magnet, and likely to scratch easily.

    The screws and washers for mounting the fans and radiator have a very nice matte black coating, however the mounting hardware for the pump has an odd finish. It's not ugly by any means, and almost looks like mill scale, but shiny. The mounting plates for both Intel and AMD are done in chrome, and the Intel backplate is plastic.

    The fans are some of the nicest we have ever felt. The ML series Magnetic Levitation fans are very heavy with a glass fiber reinforced frame, which is incredibly stiff and strong. They have a 4-pin PWM wire which connects to the pump directly for control, and the wire is an average length and is not sleeved.

    Installation & Contact

    Installation on our AM4 system was incredibly simple. The H100i PRO uses the stock AM4 backplate as well as the stock hold downs. After cleaning off the pre-applied thermal paste the Intel bracket is removed and replaced with the AMD bracket which simply clicks on to the bottom of the cooler with no tools and only a small twist to engage or disengage the pins from the key ways. Following that the "loops" and thumb nuts are loosely attached to the ears of the mounting plate. After applying thermal paste the cooler is gently lowered onto the CPU, while hooking the "loops" over the hooks on the stock AM4 mounting points and evenly tightening the thumb nuts.

    The fans mounted to the radiator using the included hardware with relative ease. While the threads are well done, there was some paint remaining which caused a bit of resistance. The screws included for mounting the fans to the radiator are a bit too long, as they do make contact with the fins when fully tightened, however this should not post any issues as the mounting holes are not in line with any off the radiators channels. Mounting the radiator to the case was more of the same, however unlike other all-in-one coolers we have tested, Corsair does include washers for these screws, which is a very welcome addition.

    Wiring is very simple as well. Coming off the pump head is a 2-Pin wire for connecting to your motherboards CPU fan header, a wire that splits into two female 4-Pin PWM connections to connect the fans, as well as a SATA power connector. On the left side of the pump head is the USB Micro-B port for connecting the H100i PRO to an internal USB 2.00 header. Everything was extremely straightforward, our only suggestion to Corsair would be to make the SATA power cable longer. While we had a long enough SATA cable to stretch from our power supply, those with larger cases (or shorter cables) may need an extension.

    Mate Comments

    The near perfectly flat baseplate on the H100i PRO made for an excellent mate between the cooler and the processor. Thermal paste was very evenly spread, and had excellent coverage and flow.
