Corsair H150i Pro RGB Review

Corsair H150i Pro RGB - When great performance meets RGB goodness!!

Last year at COMPUTEX Corsair dropped a hint that it is working on an entirely new series of AIO coolers which would not only be different in looks but also mark Corsair's entry into a new realm of CPU Liquid coolers. And here we are today with Corsair dropping two new coolers in the market namely as the Corsair H115i Pro RGB and the Corsair H150i Pro RGB which are not only in the much needed RGB flavor that Corsair AIO were lacking behind in but the H150i Pro RGB marks the first ever 360mm AIO cooling unit from the house of Corsair which with the current generations of Threadripper and Skylake X processors are a must for high end builds!

Thanks to Corsair India today I have with me the flag-bearer of this new lineup, the Corsair H150i Pro RGB CPU Liquid Cooler for review and I can't be any more excited than this to test this beautiful yet massive unit.

With a price tag of $170 the Corsair H150i Pro RGB is the
first of the two to initiate the Pro series of coolers from Corsair and
is equipped with three 120mm ML120 Quiet edition high static pressure
magnetic levitation fans making it a 360mm unit with an entirely new
pump design which boasts RGB lighting and support for Corsair Link
software, hence the 'i' in the name, for a bunch of features and customization. The cooler comes
backed up with the Corsair 5 years warranty.

What's in the Box!?

Corsair has packed the H150i Pro RGB in a thick and heavy cardboard box just like all of its coolers and the color scheme of black and yellow is also there that we are used to now from them with all their products but this time we also see a hue of colors in the backdrop of the image of the cooler imprinted on the front that signify the RGB nature of the cooler. All the features are neatly printed on the front itself such as compatibility, use of ML120 fans, RGB pump header and the 5 years warranty support.

Inside we find the cooler & all its components packed safely inside a molded cardboard frame which is good enough to cushion a unit of this size and weight.

Content wise the package includes the H150i Pro RGB cooling unit, three 120mm ML120 Quiet edition PWM fans, a Corsair Link cable, AMD bracket, Intel backplate, stand-offs, washer and screws for installing the cooler and fans along with the warranty leaflet and installation guide.

A thing worth noticing here is that Corsair has not provided a separate backplate for AMD platforms which is a wise move since they already come with a metal backplate on the motherboards, also the AMD bracket has a different installation process now which is more simple and quicker to which I will come later on.

Let's take a Closer Look

Corsair H150i Pro RGB is a completely different from any of its predecessors in terms of almost everything, at-least from the outside. The pump and cold plate unit on the H150i, which is an Asetek design,  is quite sleek and made out of premium quality glossy plastic. The top has the Corsair logo which is RGB LED backlit along with the whole outer lining of the black portion.

Also the Intel bracket comes installed out of the box and can be easily swapped with the AMD one by a turn and pull method to simplify the process. The micro-USB port on one side is for connecting the Corsair Link cable that the cooler comes with.

The cold plate comes pre-applied with a thermal paste and looking
closely we can see that the copper base plate is not perfectly smooth
but has some machine marks on it which shouldn't be an issue in cooling
as almost all Corsair AIOs that I've used so far had the same finish but
delivered nicely in cooling.

Corsair has used a 350mm long Polytetrafluoroethylene (PTFE) braided tube on the H150i Pro RGB which is thinner than the ones which we are used to from Corsair but are extremely flexible and not too hard like the ones on the H100i GTX that caused issues when routing them inside tight spaces! I'm happy that Corsair made these braided tubes flexible and they can even rotate to a full 90° to the pump unit for easy installation and routing.

A bunch of wires vine out from the pump unit namely as a SATA cable to power the pump, a PWM fan connector to power the installed fans and a Y-splitter to connect the two provided fans. It can surely give a few a hard time to manage so many cables protruding out near the tight CPU area but this is a good arrangement as it sheds the additional load off the motherboard fan header to power the pump and fans all together hence there is no compromise upon the performance.

The fans that comes with the Corsair H150i Pro RGB are the Corsair ML120 Quiet edition magnetic levitation fans that are 120mm in size and are rated at 1600 a rpm max which can move up to 47.3CFM of air at a sound pressure rating of only 25dB. Since this is a RGB lighting oriented cooler its a bit sad that the fans are non RGB since Corsair already has ML120 Pro RGB fans in their catalog which not only look great but would've been an apt addition to his cooler.

Corsair has used a aluminum radiator on the H150i Pro RGB which measure in at 396x120x27 mm and has a high fin density of 20FPI (Fin per Inch) which should be there for a product of this stature. The build quality of this unit is solid and doesn't feel light or flimsy from any angle, support for upto six 120mm fans making a push pull configuration for which the fan screws are provided by default inside the package earning it a few brownie points. As for the aesthetics Corsair has done nothing odd or out of the box here but just put their logo at one end creating a minimalist design rather than the usual plastic strip with logo that runs on both sides of the radiator like that on their previous models.

Time for the fun part - Installation!

Over here I'm going to test the Corsair H150i Pro RGB with my Gigabyte X99 Gaming 5P motherboard which is an Intel Haswell-E/Broadwell-E platform and also can get really hot at times.

We basically need the LGA2011-3 stand offs along with the retention screws for holding the pump in place. The ML120 fans provided with the unit are the simple ones and not the ones with a rubber grommet at the edges so using the provided washers is a good idea to secure the fans nicely upon the radiator. Also the Corsair Link cable is optional and is only needed to control the RGB lights or to set fan profiles otherwise if not used the cooler would work with the LEDs on and programmed to a breathing mode changing color each time.

Its worth mentioning that Corsair has simplified the AMD platform installation with the H150i/H115i Pro RGB to a great extent which no other AIO manufacturer has done so far. To use it on an AMD platform one just has to use the AMD bracket and tighten the cooler upon the default plastic standoffs that the AMD motherboards come with making the installation extremely simple especially for users like me who use the Asus X370 Crosshait VI Hero that needs to have an extra plate removed from its back to install any other after market cooler that has its own backplate!

Once installed and ready I'm very happy with the outcomes as the installation is very simple for this cooler on any platform whatsoever. Since the radiator is thin measuring in at around 27mm the total thickness of this unit even with the ML120fans on is just over 50mm making it widely compatible with most of the chassis that support a 360mm radiator unit. The tubes are flexible and can be turned and twisted in the desired fashion which eases the installation process manifolds even inside a closed chassis such as the Corsair SPEC Omega which I've used here. Even though there are a lot of wires going in and coming out of the pump area tucking them in is not big of an issue and can be done skillfully with patience.

Let's put it to Test!

For testing the performance of the Corsair H150i Pro RGB we'll be using the following test bench -

CPU: Intel Core i7 5930K

Motherboard: Gigabyte X99 Gaming 5P

RAM: Kingston HyperX Predator 16GB DDR4 3000Mhz

Cooler: Corsair H150i Pro RGB

Graphics Card: MSI R9 380 Gaming 4G

Storage: Corsair Neutron XTi 480GB

Power Supply: Cooler Master MasterWatt Lite 700

Case: Corsair Carbide SPEC Omega

OS: Windows 10 Pro 64-bit



Before I move on any further its noteworthy that the Zero RPM mode, which is a new addition and exclusive to the Pro series coolers, is only available if you install and use the Corsair LINK software and cannot be accessed otherwise. This feature turns off the fans completely till the coolant temperature doesn't exceed 40°C and I repeat that its the coolant temperature and not the CPU temperature so be vary. Overall its a welcome addition as not only it eliminated the unnecessary noise production for idle systems but it also brings these coolers in sync with Corsair's PSUs that boast a similar feature such as the AXi series.

Coming back to the testing of the cooler firstly, the CPU is kept at
stock speeds with boost enabled and temperatures are measured both at
idle and at full load. Then we overclock our Intel i7 5930K to 4.5Ghz at
1.75v which is a bit more than what my chip requires to reach that
frequency but I had to add some extra heat to it, the same process as
that for the stock speed testing is repeated. Temperature is measured
using HW monitor with an average being taken of the temperatures
recorded on all six cores. MSI Kombuster utility is what I prefer to
stress test the CPU at all twelve threads, I run it for a good 15
minutes before recording the temperatures since by then the temperatures
reach a saturation point.

Secondly, the pump is plugged directly into the SATA connector while the
fans are plugged into the motherboard fan header via the provided fan
extension cable. Fan profile was kept at default from the BIOS itself to
rule out any discrepancy whatsoever.

The readings would be shown in delta temperature that is after
subtracting the ambient temperature of the room while noise levels are
recorded from a distance of three feet from the cooler which is a
reasonable and practical distance for such tests.

Temperature wise we can see that the Corsair H150i Pro RGB does a
fabulous job for a 360mm AIO cooler especially at overclocked
frequencies where it beats similar sized 360mm AIO coolers which is a direct compliment to the improvement in design by Corsair with the pump on this unit. Its noteworthy that the Corsair H115i Pro RGB is near identical in performance to the H150i Pro RGB which is because the H115i Pro RGB uses higher static fans in comparison and the difference between these two units can only be substantially felt once the coolant really heats up and the need for the third 120mm fan on the H150i Pro RGB really comes into play to cool everything down which is only bound to happen under extreme prolonged load on the CPU or while working in a hot room such as in peak summers. Considering my ambient temperature is high and the
fan profiles are set to default I'm sure if you set the fan speeds to
full or to performance in a cooler environment the results would be even
better.

The cooler is a bit noisy I'd say when the system is under full load but
at idle state the units is barely audible. Considering its size and the
two 140mm fans that come into play the cooler is one of the quietest
coolers in its category if not the quietest. This is an improvement over
the previous AIO designs from Corsair which tend to be noisy hence the use of ML120 silent
edition fans did the job for Corsair offering quieter performance for
this unit if not RGB rich.

My Verdict 

Corsair has always brought out some unique AIOs over the year most of
them improving over where their predecessor fell short and the same can
be said for the Corsair H150i Pro RGB. The H150i Pro RGB has some
welcome features that easily outweigh its cons.

The radiator and pump are all solid in build and look elegant from every
possible corner with no unnecessary gimmicks! Sleeved tubing is really
robust and flexible which is something I love as I've always felt that
Corsair tubing has been a bit too rigid but not over here. Cooling
performance is
really good for a cooler of this category, probably the best amongst the widely available AIOs, and its true power is seen
when the processor is overclocked so yet again its proven that this
cooler is only meant for people who plan to run really hot/overclocked
systems as at stock you'll be better off with a smaller unit. Corsair
H150i Pro RGB is one of the quietest 360mm AIOs out there today and that
is all
because of the improved pump design along with the use of ML120 quiet
edition fans. They've compromised raw
performance at the cost of silence but you can always swap them with
aftermarket fans including Corsair's own ML120 Pro RGB fans to not only
reap the full benefits of this cooler in terms of performance but also
to complete the whole RGB look that the unit is aimed at.

The RGB lighting on the pump is really soothing and well balanced while
the Zero RPM feature is something that every other brand should be
taking notes from, a very simple but highly effective move.

"Corsair H150i Pro RGB is a Pro in terms of balance between much needed
features, distinctive yet elegant looks and to the point pricing. Highly
recommended for someone who's looking at building  a high end system or just
want a cooler to make his rig stand out from the crowd!"
