Great looking, good performance
Pros: Awesome look, great tubing, silent pump, not that hard to install, load temp are great
Cons: Idle temp could be better, missing washers in the box, default fan are not that good, limited fan controller
I recently bought a H80i from Corsair webstore and here's my tought about it (I'm coming from a Hyper 212 EVO AP-15s in push/pull).
Spec:
MB: Crosshair V Formula-z
CPU: Phenom II X6 1090T @ 4.1Ghz - 1.42V (load), CnQ on
Case: Antec Eleven Hundred
Installation:
The unit was fairly easy to install, the most pain was to get the washer on the radiator. Speaking of the washers for the screws, well, there were 4 missing in the package.
Not a big deal for me since I use the silicon ones bitfenix include with their fans, but it was quite annoying to find mounting piece missing.
Fans:
So, I started to install it with the default fan and, let be honest, it was a vacuum and grinding feast. I downloaded the lastest firmware and it fixed most of the grinding, but they were still loud even at lowest RPM possible with corsair link. I finally decided to switch to AP-15s and it fixed all of my issues with fan noise, altough I had to plug them in my motherboard; Corsair link only having "loud", "louder", "loudest" option (40% to 100% fan speed).
Temp test (CPU temp):
Going to the temp, I must admit, I was disapointed with the idle temp, going 5C higher than my 212 EVO! I decided to start a Intel Burn Test and, after 10 normal pass, the temp capped at 48C, wich is 10C cooler than my EVO, so thats a win in my book
EDIT: I re-did a couple round of IntelBurn Test this morning with my AP-15s at 100% and my temps never went above 44C, near 15C cooler than my Hyper 212
The high idle temp are probably caused by me running the AP-15s at 600rpm at idle
EDIT 2
So, I finally did test with 3 different fan configuration (Phenom II X6 1090T @ 1.4V), ambient is 25C
I do 10 pass of IntelBurn Test V2 @ Standard - Fan IDLE = 40%; LOAD = ~80% (depend on the temp)
EDIT 3 - 1.5V
With such great temperatures, I asked myself why not going to 1.5V, something I could never go to with my Hyper 212 EVO. I set Every fan of my case (including the cpu ones) to 100% and launched 10 "Very High" pass of IntelBurn Test V2
It's a great cooler, 54C maximum (ITE chip temp 1). Imagine this thing with the default fan @ 2750rpm (AP-15s are 1800rpm max), if you don't mind the volume level, the cooler might even be better
TIM:
I decided to change my TIM to MX-4 (pea method) and found no change in temperature compared to the default TIM, so great job Corsair with great quality TIM.
Other:
The RGB lights are awesome, but they dont quite look like LEDs, more like if it was an "image" printed on the surface of the unit, wich looks really good. The Corsair link software for LED control is awesome, altough pulsating the LED has just a choppy and buggy "feel", decided to change the color from liquid temperature (WHITE (25C) - ORANGE (40C) - RED (50C)) and it works

Conclusion:
The Corsair H80i is a great cooler that looks even better in person. I will play with it around and update my review if I find something else.
Here's my first review and sorry if the english isn't that great
