CORSAIR Hydro Series H100i Water Cooler

100% Positive Reviews
Rated #1 in Water Cooling


Pros: Keeps the CPU cool period

Cons: Corsair Link Hydro software can conflict with other fan software

OK I will start with this, I am new to overclocking! However, I have been in IT since 1974 so hang with me and I will try to give you the details on this what I think is an amazing water cooler! This is what I am running

ASUS Sabertooth FX R 2.0
AMD FX-9370
Corsair DDR3-2400

This Corsair Hydro Series H100i is keeping my rig cool running core speed of 4966 Mhz and memory running at 2483 Mhz on the NB. I know I can clock it faster but I was not looking for a speed demon. I was looking for steady, reliable, rock solid, and this ASUS TUF matched with this Corsair water cooler was a match designed to be solid. I could write a bunch of words about my system but this cooler is what you want to know about and from my experience so far it was easy to install but then again I have a Cooler Master HAF-X Case which mounted the cooler on top of the case in screw holes already there for the cooler. There is no fluid to deal with it comes already pre-filled. The cooling head for the cpu comes with thermal paste already applied to it and protected by a plastic cover. The fluid lines are fairly flexible. I am pretty sure they will not leak unless they are really abused.


Pros: Link software, Solid tubing, Great fans

Cons: Pump has gotten a little loud at start up.

That is all... buy one!


Pros: Link software Monitoring,great tubing,low noice,Amazing Fans 2700RPM (wich are better than the ones you buy seperatly SP120 with colour ring)

Cons: All the cable connectors for the link and fans are Right in the middle of youre Case,


You get this Unit for around a $100 on ebay,wich is realy not much, if you compare it to a very good aircooler(Noctua NH-D14 at a 70-100$)
at almost at the same Pricing range.

The Corsair H100i cools well, installs relatively easily, and inspires confidence in its longevity. What more can you ask for when it comes to cooling?

This is a great step forward from there older version the H100 wich was noicy stiff tubing loud fans ,
I mean the fans in this unit have an RPM range of 2700 Rpm
wich are faster than the sp 120 that you buy seperatly.
Wich are at an rpm rate of 2350 RPM and a 62.74 Cfm

The H100i almost outperforms any good air cooler ,and it is the first step into watercooling,without spending tons of money,and still acheiving water cooling like cooling quality.

Corsair is the first company we've seen to use an Sata power connector for a device that has nothing to do with storage. A pulse wire on an adjoining cable feeds a signal to the motherboard to prevent "fan not functioning" boot codes.

Easy Installation and everything you need is inside the package,
availeble for all sockets right out of the box.

I will defenately recomend this unit any day.


Pros: Fair price, pump nearly silent, cools very efficiently, handles heat spikes better than air, can change led color and fan speed

Cons: Unbearably loud OEM fans at 38db, block surface not lapped smooth.

For me, this cooler is perfect. It cools the hot FX-9370 extremely well, fits in my Fractal case perfectly, and has a bunch of extra features that the competition doesn't have. The unit has a cable to a motherboard USB header, and this allows it to provide a unique level of interaction through the Corsair Link software. You can adjust fan speeds individually, by selecting one of many profiles such as Quiet or Performance, or you can set your own fan speeds with a set % or RPM, and even make your own temp / fan speed profile. You can adjust the LED on the pump in many ways: it can stay one color, any color in the rainbow to match your build, it can pulsate off and on slowly, it can rotate between any 2 or 4 of any colors you choose, and you can choose three colors to relate to different temps.

Install was as easy as any air cooler for me. I'll never understand why some reviewers elsewhere had such a difficult time with it. I did not use the pre-applied square of thermal interface material, I never do that on principle. I applied Tuniq TX-4 which has often been reviewed as providing the lowest temps, biggest temp difference, and best performance... It was my very first use of it so I'm not biased at all. Any modern TIM will be fine.

The included fans are garbage. Let me be a little clearer, the included fans are louder than my vacuum cleaner. Even at the very lowest possible speeds, they were still very noticeable inside my oem sound-deadened Fractal Design case even with all my added sound deadening and even using fan silencers and rubber washers.

I quickly upgraded to Cougar PWM Hydro-Dynamic-Bearing fans which are 17.9db at highest speed. They are absolutely silent at mid or low speeds. The temperatures even went down! You do need PWM fans if you want them to be controlled by the Corsair pump.

Well I love it and I would buy another one in a heartbeat. I haven't had to do anything with it other than change fans. Zero maintenance is what I like! No fiddling with tubes, fittings, leaks, refills, expensive pumps with no features, reservoirs, or other constant attention. This needs no attention after install smile.gif



Pros: Easy install, Looks great, Works amazing

Cons: Havent found any yet ;)

Used this cooler for my first build, so easy to install. The mounts for the pump are great very secure. I like the idea of the pre-installed thermal paste to, made the install a breeze. Have been recommending it to all my mates. So much easier than trying to find all the components for a full setup, and its half the cost.


Pros: Easy to Install, Corsair Link Software, No maintanence

Cons: Fans Loud at Performance RPM

The Corsair H100I water cooler is a great way for people to get introduced to water cooling, without going into custom loops. I myself am not concerned about noise, but if you have the fans set on performance mode they can be very audible. Otherwise they are relatively quiet for the performance they provide. Installation is quite simple for the AMD platform, I have no prior experience with the Intel mounting hardware. With my AMD FX-8350 OC to 4.7Ghz I run at 48*C under full load. I upgraded from an Hyper EVO 212 and experienced a GREAT improvement in my temps. The Corsair Link software is very nice, you can customize the LED on the H100I to any color you like, and can also have it correspond to the temp. Also, you can have the software automate actions based on certain temps, such as send you an email at high temps, or completely shut the computer down. Also there are customizable profiles available for certain applications such as benchmarking and gaming. The fan speeds are fully programmable and it displays your core temps and fan speeds are in easy sight. Overall, this is a great product and a major improvement over stock heat sinks and air coolers.


Pros: Cools Great, Fits in most cases, Easy to Install, LED on waterblock

Cons: Fans and Pump can be loud, Corsair Link can play up

Very nice WC, I bought it to cool my i5 3570k, and it is running at 4.5 GHz with around 30 degrees C at idle, and mid 60's at 100% load. The only problems i've had are the fans and pump being loud, and an issue where I couldn't get Corsair Link to work properly, which fixed itself after a while.


Pros: -Great Quality -Quiet -Easy Install -Cool Temps

Cons: Some might replace stock SP120, they were decent but I replaced anyways

I have this installed in my NZXT Phantom 410 Mid-Tower, it was a tight fit but it works. The fans did make a high pitch noise when first installed then I upgraded the CorsairLink firmware for the software and it went away, quiet as can be. Helped out a lot. Stock Heat-Sink was average 33c, Corsair H100i average is 23c on a stock i5-3570k 3.4GHz, overclocked to 4.3GHz get average around 26c in quiet mode and 23c at 50% fan strength but I have all quiet edition fans so still can't hear much noise thumb.gif



Pros: Tubes,LED on block

Cons: Fans are loud at high RPM

I love this cooler its easily 10c cooler than my H70, the tubes i find are better quality then that hard plastic, they have more flex to them an look better. The led on the block can turn to what ever color you want. It has a feature where the LED will monitor your temps, if its cool it will be blue, yellow for warm and then red for hot. The only thing that i found to be a con for this cooler are the fans they can be loud at high rpm, most people will only have the rpm high when running benchmarks so the fans can be quiet at half the speed. If your looking for a cooler then i recommend it !

Troubleshooting/Known Issues:


Many people are complaining about dead units out of box and problems with firmware versions. I myself just had one that was dead in the box. If you don't want to wait 2 weeks to be able to use a new build (RMA time from Newegg), I recommend purchasing a fan cooler as a backup in case something happens to it. I definitely will next time.
