Easy install. Works perfectly right from the start.

Summary: This Hydro Series kit keeps my CPU very cool no matter what I'm doing. This is perfect for any High end gaming, editing or general workstations. My CPU is a i5 4670k currently clocked at about 4200mhz (not too much overclocking). This keeps my CPU at under 32'c at all times. Must have some technical experience in order to install properly, also plan out where and how, you want to mount the radiator and fans before you actually start.

Summary: I have been using a Noctua NH-D14 for about three years and it is very reliable. But, during the summer months it labored to keep my I7-2600K cool, especially when overclocking it to 4.7Ghz. Previously, I had resisted water cooling due to my concern about a potential leakage, but I wanted to get the temperatures down and a closed loop system by Corsair looked like a good alternative.
Summary: Have been using this for about 2 months now, using it to cool an i7-920 which used to idle in the high 50's. After forgetting that rectangles are not squares and mounting it the wrong way at first, I got it installed correctly and it pretty much instantly dropped my CPU temps by 15 degrees across the board. Using Prime95, my old stock Dell cooler would reach 75 C in seconds while this thing keeps the CPU under 65 even after 15 or 20 minutes.
Summary: I was lucky enough to get this on sale when it was only $74.99. This is a fantastic closed water loop. I just built my first gaming rig using an i7-4770k (got it at the same time for $289.99) and an ASUS Maximus VI Hero mobo ($180). I never tested it with the stock fan, but so far, I've tested my 4770k at 4.2 @ 1.030 adaptive volts, and averaged about 45-50c. I then upped it to 4.5 @ 1.285 adaptive volts, and they highest I've hit on BF4 and other games was 66c.
Summary: During the installation, (LGA 1366) there were hardly any instructions for the Intel LGA 1366 socket type. It wasn't even in the manual as a supported type. I looked online and found it used the same screws as the 1155 and 1156. After that, it looked like the bracket was held on VERY loosely. After looking online again, it's supposed to. It tightens up when putting the finger screws on. After i had it all installed, it worked like a champ.

Summary: I had what I thought was a good quality water cooling system. Until it stopped working after just 13 months - of course it had a 12 month warranty. So I looked around, checked reviews and feedback, and decided on this as a replacement. Installation was quick, the thermal compound is included, and all I needed was a screwdriver. As a bonus, the logo lights up so you know that it's on. It's so quiet most times, you need that.
Summary: In AMD FX 8350 4.0GHZ (stock), my system reached 48C idle and 80C when max loaded. (Pull setup, on corsair 600T) Now temps are 28~30C idle, and 42C max loaded. Balanced profile. If I set maximun performance, it comes really loud, but it can reach 25c idle and 39C max loaded. Nice cooler. Quite big, not so much. Love it.
Summary: Installation was quite simple, and it works really well. I've been running this on push pull with quiet sp120's, on my overclocked i7 2600k. Running 4.6ghz at 1.387 volts, keeps below 70C while running OCCT avx linpack Would def recommend, have been running it for around 6 months now no problems.
