Pros: Fit on my I7 3770K processor without any issue. Brought CPU temperature down almost 50 degrees Fahrenheit. Mounted the fan onto an Asus Maximus V Formula motherboard. Cooling fans are only slightly noisy within a Thermaltake Overseer RX. However, the fans are virtually inaudible when combine with the case fans.

Installation was within 1 hour for a product I had no experience with.

No vibration from fans.

Cons: A slightly thinner product would make mounting the cooler a little easier. The products I have, forced me to remove the cooling fins from my GSkill memory. However, this is a minor inconvenience. Because I have two of the same motherboards, processors, memory, etc. I tested one of these coolers to see what types of issues I would see. In general, no major issues except for me not taking into account the dimensions of my memory sticks. For anyone reading just make sure your case dimensions and internal components sizes are known before purchasing. This wasn't a product issue though and makes me only mention this for anyone interested in the product.

Other Thoughts: I recommend this product. I have now been using the product for a few months with NO concerns.
Occasionally, I hear air/water moving through the unit. This happens once a week at most. In general, I don't want to attempt changing water inside of the unit. Thus far, I haven't had any issues or concerns.

Because of the placement of my memory sticks on the Asus Maximus V Formula, I will probably go with a smaller cooler in the future (on my other machine).

Due to the amount of difficulty end users might have performing the installation properly, I would make sure video footage is available to customers and is diverse enough to cover installation with older and newer products; motherboards, microprocessors, memory, etc...

Make sure measurements of the product are available online or via a diagram that is included with the product.

Pros: Looks great, pwm fans

Cons: The block is mediocre. I'm getting peaks of 80+°C on my 6700k using ic diamond thermal compound. The pump, which is not pwm controlled, has a high pitched whine to it and is way too loud for the price.

Other Thoughts: I would recommend the h100i gtx or h110i for a bigger rad. There's a reason they made newer versions

Pros: Works great.

Cons: Fans are insanely loud. I read about the loud fans in a lot of reviews and figured people were just being picky. Not the case. If you get this, order some Vortex HDB fans and save yourself the time you will eventually take to swap them out. With the new fans it is a great cooling system.

Pros: Keeps my CPU temperature 10 degrees (on average) cooler than the best air cooling solution
Easy installation
Well designed
Most good cases support a 240mm radiator so this is perfect for many users

Cons: Instructions could be improved
I'm confused on what the cooling pump should be set to in the BIOS as it plugs into one of the CPU fan connectors on the motherboard (as instructed in the manual). I have control in the MB on fan speeds and there is no indication in the manual on what this should be set to. I don't want to overwork the pump if it isn't necessary.
The unit came with 2 120mm fans. One of the fans will run at 2800 RPM on full speed while the other fan won't go above 1000 RPM. I have 4 fan connectors on my motherboard and no matter which connector I plug the 2nd fan into it won't go above 1000 RPM. The 1st fan will always go to 2800 RPM no matter which connector I plug it into. I'm unsure what is going on here or if the 2nd fan has a flaw in it.

Pros: Easy to install
Cheap, as I got it on sale
Runs really quiet and keeps my i5-6600k oc to 4.2ghz at a cool 38 celcius on average. Under load I've not seen it rise above 48 celcius.

Cons: No cons as of this review.

Other Thoughts: Get it, you won't regret it. There are other models from Corsair, but they just don't have as good reviews on Newegg.

Pros: Pump unit seems well made, runs quiet. Nice glowy blue disk looks good on my motherboard.

Cons: I had a few problems with the installation, which looks like it should have been easier than it turned out to be. My case is an NZXT 210 - admittedly one of their cheaper models - but it does have the 240mm mounting space at the top. The radiator just barely won't fit. Lacks about 1/2" clearance. Now, this "one size fits most" issue has been true of PCs since the old DOS days, and nothing says anywhere that the unit WILL fit my case, but still. Frustrating (it seems Steve Jobs was right, after all). Also, the retention ring has to actually clip onto the mounting bracket itself as part of the initial assembly. It took a few minutes for me to figure this out as the instructions were unclear. Currently, the unit is running, but the radiator is balanced on the case with the side panel removed, until I can order a new case.

Other Thoughts: I didn't take an egg off simply because the unit wouldn't fit my case - I accept the blame for insufficient research on that point. But some of the hardware parts seem cheaply made, and I had a hard time seating the pump unit onto my motherboard because of that. Be careful; it feels like you could snap the heads off those standoff parts if you applied a little force. The other issue I had was that after the installation my PC failed to boot with a "cpu fan speed" error. I had to go into the bios and select a manual override.

Pros: Keeps my OC Skylake very cool even under load, great fans that come with it, very easy to install, love the corsair emblem that glows when plugged in.

Cons: Nothing yet, but I will change if necessary.

Other Thoughts: I would recommend this product simply because it's great at what it does.

Pros: I bet it's cool when it works

Cons: Well first off, one of the mounting screws broke, completely broke.. and there is absolutely no way to get ahold of customer service. I've tried and tried but their website loops me back to the homepage.
Then there's the second part, after installing this (still need a screw) 4 beep error. Means my processor is dead, how the hell does my processor just die from this.

Other Thoughts: It would be great if customer service would get ahold of me.

Pros: Perfect combo with a mastercase pro 5. Keeps my i5 6600K nice and coooool

Cons: Pump crapped out after a couple of weeks.. Refunding

Pros: •Keeps my i7 4790k oc 4.6ghz @ 28-30C idle; 79C full load
•Looks much better in a build rather than a clunky cooling fan
•Customizable rings on the pump
•Extremely easy installation (first PC build)

Cons: The screws to hold the radiator onto the case are cheaply made. Three of the screws had their heads snapped off while being placed into position with hardly any force being applied. Not a problem though, won't knock an egg off because it's performance cancels that out

Other Thoughts: For those wondering if it fits, I attached the radiator on top of my Rosewill Thor V2 case. All I had to do was remove the top 230mm fan and place in the new liquid cooler and it fit in perfectly.
