Summary: Love it . Cools great for standard PC and is very quiet. Keeps the processor darn near room temp. Kind of a pistol to install however in a basic case unless you get one already equipped with a 120mm fan The little radiator is just a little too big to really fit smoothly in tight places. Guess there is no way they can change but so much and still be cheap and mass produced.
Summary: So I've had the hardest time keeping my AMD FX-8120 cool for some reason. I've went through two different air coolers and finally decided to look into water cooling after my CPU got up to 92C (and shut itself down) whilst trying to encode a video. And while I wasn't really expecting a huge improvement on my temps, this water cooler has definitely convinced me that I should probably never go back to air cooling ever again.
Summary: I bought this as a replacement for a stock Alienware cooler. I chose this one over more expensive models simply because the mounting kit was similar and I hoped to mount it without pulling the motherboard to replace the back-plate. It worked. But the ease of installation aside, the cooler works perfectly and is every bit as capable as the one that came stock in the Alienware.
Summary: Very happy with this purchase. My AMD FX8350 had the stock cooler fan and it was very loud and it didn't perform very well. CPU was reaching 68°C under heavy load and sounded like an airplane taking off. So i decided to buy this quiet edition. Temps now are 35°C on iddle and 55°C when processor is at its maximum and I can even hear my thoughts LOL. I don't OC so this temps are great for me.
Summary: I just put this on my 3570k. It keeps my cpu 20-15 degrees c cooler while gaming. Playing battlefield 3 with factory heatsink and fan i was running at 71 degrees c. With the h55 it runs at 45-50 degrees c. Only thin it the fan and pump both are three pin connectors and my mobo only has one three pin connector so the corsair fan attached to the radiator runs at full speed all the time, But its not a big deal to me if/when it burns out i will just replace it with another...
Summary: Very nice and Quite, easy to install, came with all the mother board hockups. Direction were hard to follow... but most people doing this...been around the block and know what they are doing. If this is your first time... go to youtube and watch a few video on this before attempting to do this.
