Pros: I have a new computer with the 5960x overclocked to 5ghz, and this thing keeps me in the safe operating temps for the past few months. 65c-73c max temps after hours of gaming every night(my room is normally 71F).

Cons: I'm shocked by its great performance so far.

Other Thoughts: For anything below EXTREME overclocking madness...you cant go wrong.

Pros: OC my i7 980X with ease !

Cons: None

Pros: - Easy to install
- Looks great
- Steady temps
- Acoustic throttling works well
- Even at low fan speeds it knocks temps down significantly

Cons: - More expensive than an aircooler

Other Thoughts: I've had the H100i v1 for approximately two years now. So when the chance to upgrade to the V2 came around I knew that this was going to be an excellent cooler. The quality of this unit is beyond my V1 unit. Everything seems to be tighter and more refined. The software is better and easier to work with as well.
Temperatures are around the same on my rig. I am running an AMD FX-8350 and at idle I'm around 56 F with the fans on low. When I push the CPU during a game, Guild Wars 2 for example, the system gets up to around 65 F before I have the fans on the radiator set to ramp up. At this point the noise goes up (acceptable, I have headphones) and the temps drop back to 56F. I have it scheduled to not immediately drop the fan speeds back down when an acceptable CPU temperature is reached so that things don't constantly vary between loud and quiet while the temperatures yo-yo up and down.

Pros: As expected from a good cooler, it keeps my CPU nice and cool. I idle in single digit degrees Celsius; games can get in the low- to mid-20s. A little while of Prime95 stress testing put me in the mid-30s. Overall, pretty solid improvement over my Noctua DH-14.

Speaking of air cooling, the fans that cool the radiator are quiet. You’ll hear much more of the radiator itself than the fans. That was one thing that pleasantly surprised me, as one of my concerns was that I’d have to hear some constant pumping noise. Instead, it’s more like a low hum. Granted, it is a constant, consistent hum, but a low hum nonetheless.

Other than those things, it’s a pretty straightforward cooler that does a solid job with minimal noise.

Cons: It’s not easy to install in a way that cable management is also easy. The cables on the fans are not long enough to reach to one of the cable management ports in my case (immediately above the row of ports/top left of CPU, top right of CPU near drive bays). What ends up happening is I can get the cords over to one port, then I just have to tie them to cords that actually reach into one of the slots.

The reason this may be a problem is because the fans can easily get caught on or repeatedly hit the cables if you don’t find a place to stow them. This happened when I first powered up my computer after the installation, as one had come loose where I had put it and fell once I stood my tower upright. It certainly doesn’t make for a pretty sound.

Another thing is the mini USB cable that appears to provide some power to the heatsink portion of the cooler. Perhaps for the light that is on there, I’m not sure -- I could probably find out in the manual. This cable also isn’t long enough to go in a cable management port and reach the USB pins on the bottom of the board (which typically is where USB is). Again, stash the cable to the side and hope that the computer doesn’t really move.

Other Thoughts: Much about this installation was unclear, and I sometimes had to go back and take some stuff off because I had something that wasn’t either the correct part or it wasn’t in the proper configuration. Here are some things to note if you get this cooler:
- remember to check for rubber stoppers where the radiator hooks to the case. This cooler didn’t come with any, so you’ll have to hope your case does
- there are 3 types of risers, and for some reason, the AMD and one of the Intel ones look very similar. If you’re installing for an Intel cooler, flip ahead to the AMD section before putting on your risers to make sure you have the ones for Intel.
- the cooler already has the Intel heatsink on it; the only one you’ll see in the box is for AMD coolers
- you will need your CPU bracket to install this cooler, or at least, the recommendation appears to be to have this. If you previously had an aftermarket cooler (like I did, the Noctua DH-14), you might’ve remove the bracket because that cooler didn’t need it. Dig it out of a box and put it back on, because this one does.
- while I’m not 100% certain, I highly doubt you’ll be able to reach your GPU with this. Considering the hassle I had getting it to properly fit my CPU, I’m not even going to try on my GPU.

Pros: 5 year warranty is nice. I hear they will replace your parts that get water damaged. That’s nice service. You will certainly get top notch cooling at a good handful of degrees warmer than ambient... but...

Cons: I know watercooling sounds so “cool” and is so tempting. I fell for it too. But when I got it, I noticed something. It was a lot louder than my Noctua 14. And barley cooler. And the pump noise, that vibration is audible too, and really REALLY annoying after a while. And I was totally confused until I started doing some research and comparisons. The benchmarks don’t lie, let me summarize: While this water cooler does cool about 3° better than watercooling, it does so at over twice as loud of other cheaper high end air coolers. (over 12db louder) And silence is golden to me. I don’t want something that sounds like a muffled hair dryer on high and a pump drone noise on low. Only people who have never built a computer before don’t care about sound levels.

If you want watercooling performance at 30dB (silent) instead of 43-60dB (that’s not twice as loud, dB is a logarithmic scale, 30-60 magnitude is 1000 not 100) I recommend getting the The Thermalright True Spirit 140. At ~$50 it’s half the price, half the size, half the noise, on par with performance and you never never have to worry about the water eventually leaking or the pump dying out. Water eventually wears everything down, anyone ever had an aquarium? Pumps don’t last forever. The pump, the tubs, the water block, the radiator, and all the connections is a lot of failure points. But let’s not worry about that, let’s say it’s going to be perfect and run forever, but if you just focus on performance (sound levels and performance) and price, this does not make sense. I know a lot of watercooling fanboys will not like this. I’m just trying to save you some possible headaches and money. Get a Thermalright True Spirit 140 or a Noctua 14/15 and use some Phobya LM thermal paste (the best as of the writing of this review, you can buy it here at newegg) and enjoy the silence with no worries and top notch performance. Maybe watercooling will get a smaller quieter better performing solution one day soon, but that day is not today.

Other Thoughts: Googling around the internet, Yes there are reports of this leaking, yes this brand new one, yes this V2. Yes this is just a rebranded H100i GTX. That’s kind of nerve racking for someone that *needs* their computer working all day every day. It's not worth it for me, but maybe you're deaf and don't need a computer to be working, and you like hassle, and need those extra 3 degrees that this water gives over other high end air solutions, this could be good for you.

Pros: This cooler works very well and it was very easy to install it on my AMD FM2 5800k APU. I was able to make it fit in a micro ATX case but just barely. Quiet operation and it cools very well as my APU is now overclocked 800mhz. and is still running 15c cooler than it was at stock speeds with the stock air cooler. The Corsair link software works great for monitoring and making adjustments to the fan and pump speeds as well as changing the light color to anything you want on all three of the performance settings. The build quality is top notch with the system sealed and ready for use straight out of the box. Works with just about any modern processor.

Cons: There is no easy way to mount the radiator on the outside without making a large hole in the case due to the coolant lines being connected and sealed shut so make sure you have the room on the inside or be ready to make a hole large enough for the block to fit through. The Corsair link software doesn't read the APU temperature correctly but most software doesn't.

Other Thoughts: This is my first liquid cooler and I'm impressed. It was super simple to install and it works just like it should. I'm amazed at the difference in temps with my APU running 800mhz over stock speeds and still getting a 15c drop in temp. Under a max load it tops out at 42c but stays at 25c most of the time and all while on the quiet setting.

Pros: I compared this cooler back-to-back against the original H100i cooler on the same system. In short, Corsair has tweaked the design to optimize it, but it's not radically better. Basically, the radiator is more efficient and the fans run at lower RPM. I found that in Quiet Mode (using CorsairLink's presets), the temperatures were actually 2C higher both at load and idle, while noise levels were the same at idle but 2-3dB lower at load.

The real changes are in "Performance" mode, which was intolerably loud before. Now Performance mode yields temperatures similar to the previous cooler's Quiet mode, but with slightly lower noise levels.

Cons: Don't kid yourself - lower RPMs do lead to higher temperatures. There is no way this cooler can match the old H100i with it's ultra-loud 2700RPM fans.

Also, while installation has been simplified versus the H100i (much better bracket, no SATA power cable), the hoses are so thick that they actually have become hard to bend. And because of this issue, I found that they basically touched my rear 120mm case fan. This wasn't a problem with the older H100i.

Finally, despite being the same size class, this cooler is actually thicker than the H100i. Whereas the H100i fit perfectly in my Corsair Carbide 500R's radiator compartment, the H100i v2 is too thick to fit without the case's top panel bulging.

Other Thoughts: Interestingly, by removing the SATA power connection that the older H100i used, the H100i v2 now draws power directly from the fan header, and it seems that motherboard controls will affect both fan speeds and pump speed. I didn't find anything in the manual regarding whether this is safe, but typically, coolers do not allow you to slow down the pump. Doing so most definitely allowed amazingly low noise levels at idle, but long-term this could cause a problem.

Pros: my cpu is ice cold.. nice cooler

Cons: this will take up a usb header on your motherboard....

Pros: Clean
easy to install
works as intended

Cons: still tubes, but thats fine not an issue to install.
Missing 8 washers, says it comes with 16 and i got 8.
Instructions are a bit confusing and not very instructive. (possibly not for beginners?)

Other Thoughts: Over all i would recommend it, my temps went from 70c to about 50-55c with a max trottle 4790k at 4.4ghz.

Pros: I can't say enough good things about this card. It's quiet! Runs very cool. everything is running at ultra

Cons: I wish the coolant tubes were longer as I would prefer to buy another one and hook it up. But I'm doubtful it would reach in my full tower.
