Pros: It's reasonably smart, keeps things very cool. I'm running a i7 6 core at 4.3ghz and I've not seen 35 degrees C yet.. It's not nearly as loud as the other two options I've come across.

Cons: slightly smaller would honestly have been better, clearance is so tight. Impossible to remove ram once installed without reapplying thermal paste, and 10 minutes of labor. 120mm fans/matching heat sinks would be smarter for most enclosures AND allow for more RAM choices.

Overall Review: On a 2011 socket motherboards most ram slots are on either side of the CPU and close, if my ram's heatsinks were even 2mm bigger I would have had to return the this unit. Also I have a large case and I have about 1 cm of clearance from the sliding case door at best. I seriously doubt anything other than a large case will fit this unit. http://www.newegg.com/Product/Product.aspx?Item=N82E16811119245 (case I have it in).

Pros: Keeps temps considerably lower than large heat sink and fans. At low loads/temps the unit is very quiet quiet. Install is very easy.

Cons: Supplied fans are loud at 60+% very poor instructions, almost be better if it lacked them entirely.

Overall Review: I was running the http://www.newegg.com/Product/Product.aspx?Item=N82E16835709001 which was running pretty well, and the fans are super nice. However when I started some real over-clocking my temps were getting 65+degrees and the fans were running pretty hard. However the main issue I see is that with x79 chipsets/config platforms the system memory is too close to the cpu, and thus you get heat soak everywhere else. With this water-cooling unit I have yet to see above 44 degrees and I'm running at 4.9ghz I7. Under non-load you can set the fans (I do it through my case as my cool-master case has a set up for fan control) to super low levels and they become very quiet! The Ram is now in the open air and everything including motherboard is staying 10-25 degrees cooler. My normal temps are 22-24degrees.. which is nothing.

Pros: Very quick.. good connectors (hdmi, DISPLAY PORT!, dvi's), easy to over clock further, nice software additions from EVGA to review/monitor and over clock. Great fan curve control.

Cons: noisy wish Nvidia would release a driver that supports proper colour depth for display-port.. real let down.. You still can't use this card for work.

Overall Review: With no effort or voltage changes, one can add another 75mhz (total of 1225) and another 125mhz to memory is no issue at all. This raises the temp a about 3-5 degrees under full load and continuous use. I've run it at 1248mhz gpu and 238mhz vram, for 3+ runs in 3Dmark, but the temps and fan noise made me drop it back down. I would have preferred 2 larger fans going slower. This is by far the loudest piece of machinery in my rig. It's double the noise of my 4X120mm fans in my rig... at least double..

Pros: Really nice unit. Good construction, quiet fan, and probably my favorite part is the cable system is plug in what you need, avoiding dozens of extra cables floating in box.

Cons: The ATX cables are a little too short, an extra 6cm's would make installs on larger cases better/cleaner/easier.
