Price at time of Review: $109.99 from Amazon.com and NewEgg


Great performance, low noise, incredible software suite.


Fan screws are too long and hit the radiator fins.
The H100i is a powerhouse that's backed by a powerhouse control software. The H100i is the new king of the AiO market.

Our test setup is as follows:

  • Biostar TZ77XE4 Motherboard
  • Intel i7-3770k
  • 8GB Mushkin Blackline DDR-3
  • Enermax Platimax 1200W PSU
  • Kingston 90GB SSD (OS)
  • WD Blue 160GB HDD (storage)
  • ASUS 24X DVD Burner
  • HSPC Top Deck Tech Station
  • Windows 7 64-bit fully updated


Testing methodology:

All tests are run using Arctic Silver Alumina thermal compound for comparison purposes. The CPU and heatsink is cleaned with Arctic Clean and Arctic Silver Alumina is reapplied. Tests are run at stock (3.5GHz [with 3.7GHz Turbo Boost]) and a moderate OC at 4.5GHz (no Turbo Boost). The system is left to idle for 30 minutes and a baseline temperature is recorded using CoreTemp. A Prime 95 blend test is then run for 30 minutes and the temps are recorded again. The recorded temperature is the average of the four cores. Since ambient temperatures can affect CPU temperature readings ambient temps are recorded during idle and full load testing. The ambient temperature is then subtracted from the recorded CPU temperatures resulting in a Delta T measurement, (or how many degrees above ambient the CPU cooler keeps the CPU). This levels the field for different ambient temperature tests. The H100i was tested on Quiet, Balanced and Performance modes.


Here you can see the Corsair logo lit up in the default white. It’s not overpoweringly bright but it gets the job done.


You can see that under stock clocks, the H100i matched the reigning king Noctua at load, but only in performance mode. The balanced and quiet modes slipped a few degrees behind, respectively. On quiet, the fans were borderline unnoticeable. Balanced was very much tolerable, and finally, performance mode was loud but tolerable. Now let’s bump the clocks up and see how it handles the heat.


As you can see, the H100i clearly held its own. It once again matched the reigning leader Noctua (in performance mode) with the balanced and quiet modes falling behind, but that’s to be expected. Again, on quiet, the fans were borderline unnoticeable, balanced was very much tolerable, and performance was loud but tolerable.

    Thanks for the review, guys. I’ve got my unit on monday, built up a system around Fractal XL R2 with 3930k, gtx 780 (reference) and H100i mounted in front of the R2 in push mode. The pump is F***d, as about 50% of the time the rpm falls to about 780, instead of 2200 and a distinct noise comes from the pump. You would think noise will be lower with lower rpm, but nah, not with this thing (besides being a fault, that is) Full shutdown 2-3 times usually helps to get the pump back to 2200 rpm (give or take). The problem seems to be known, so I’m sending the unit back to the shop and getting Swiftech 220 instead – hope this one is better. Regarding fan noise – the only one I find acceptable is Quiet mode, Balanced is very much hearable, and Performance is far from acceptable IMHO.


    “The shear amount…” – really?

    (Yeh, it took me this many days to read to the last page…)


    In the review you speek of the standoff don’ t tighten to the motherboard.
    But what are the temperatures if they do?
    I have personel experience with a corsair H100i and by tighting the standoff to the motherboard i dropped the temps by 5-10°C.
    Just put some rubber washers behind the backplate
