keeps my i7 4790k @ 4.7GHz 1.3v under 75C under synthetic benches. only 1 core will ever go to 70 when compiling maps in hammer editor for long periods of time.
corsair link is iffy, and i never got the led color to match cpu temp thing to work right except it will just go whatever color the cpu currently is whenever i click it in the program. but it works.
pump can be adjusted from 2 speeds, quiet, and performance via corsair link
Obviously since the 6700K doesn't come with a cooler, I decided to go with a Corsair AIO to give me better temps and overclocking headroom. It does it's job, keeping my CPU nice and frosty, although fans do get quite loud, and the pump is very audible when idling. Not sure if my pump is defective, but for now, I can't really complain.
Keeps my heavily OC'd 6600k under 60. Very good looks and the interface is also easy to use and efficient. After more time with the UI I honestly am 50/50 on it. Using it with Q-fan can be a nightmare and only works half the time.
If you're looking for a top of the line closed loop cooler the h110i GT is a great option. I would put it right there with the Kraken x61 and the Swiftech 240x. It's usually cheaper than those two and therefore the best option. Only reason I didn't go with the Swiftech 240x is the fact that you can't do a push/pull config. with 2 fans on each side. The pump get in the way with 1 of the fans.
I do like the h110i GT more than the h110i GTX purely because of the hose placement on the block/pump. A lot of people think the GTX is the better product and I believe they think this because it has 1 more letter in the X. The main difference is the company that makes them for Corsair.
I originally gave this product 4 stars but I am now lowering it to 3 stars because I've had 2 of the mounting screws break off in the thumb screw. I had to contact Corsair to get new mounting hardware. Luckily I can still use it while I wait by putting the 2 remaining thumb screws in opposite corners and the temps have only raised a few degrees under load. I guess it was a bad idea to change paste and tighten it with a screw driver.....
Only had it a week or so but all I can say is WOW, its quiet cools brilliantly and the LINK software is pretty good too. As a side note always read the instruction when installing, I did a stupid and put the back plate on upside down!
Pretty good water cooler, it does make some weird noises when the fan speeds are too low though. Though it doesn't make those noises anymore because I cranked up the overclock some more.
It rattled at a certain RPM, it was one of the fans, I tightened it up and it was little quieter but I could still hear it through my headset. It definitely cools though, I haven't seen my CPU above 45 degrees C in either Firestrike, iRacing, BFBC:2, or ARMA 3. I haven't run Cinebench though. I have since replaced the fans and solved the issue, but for the price of it plus new fans, there are better options on the market.
