Rated 5 out of 5 by from Great cooler I got this cooler for the pc i was building for my brothers new system. Great product for the price!

Rated 4 out of 5 by from Bulky but good Quiet fans, quiet pump, but probably not suited to a mITX case (FD Core 500 - though I did manage to get it in with both fans attached anyway)

Rated 5 out of 5 by from Recommended for any CPUs needing TDP over 200W+ I used a Antec Khuler 650 on my AMD FX-9370 clocked at the original factory rate of 4.4Ghz but like many started to fail on me so i decided to try once again another liquid-cooling AIO unit and purchased this CoolerMaster Nepton 120XL. Have to say for the price of this unit, it works amazingly well for such a decent price! Works on processors up to 300W TDP!! My AMD FX-9370 Eight-Core Processor (rated 220W TDP) doesn't even flinch, even under load it barely goes above 45-50C and on idle or very little processing it can drop as low as 2C......yes you read that right 2 Degrees Celsius!!! I also used Noctua NT-H1 Pro-Grade thermal paste on the Processor with this AIO Liquid cooler (instead of one in box from Cooler Master): One thing i have noticed is it has made the system even faster than before! Seems like my old Liquid Cooler wasnt up to the job and was increasingly causing the system to start failing and even cutting the power due to the CPU Thermal Switch! Other notes would be that some Mobo's may need to get a fan splitter or power to fan pin splitter to connect the two fans up. Also it makes a weird dripping sound in the system as the liquid is cycling through, don't be alarmed as this is normal! One other IMPORTANT NOTE is bear with the instructions and guides as they have made them like an Ikea guide but not named anything, just pictures and the website for Cooler Master is a bit of a let down as theirs no text to the pictures, don't get me wrong i still built it fine but it did confuse me a little in certain sections.

Rated 5 out of 5 by from Very good cooler Well I did have my expectations reserved due to the price of this but it does it job really well its cooling an i7 3930k these are hot chips and it idles 35c load never above 55c with an overclock and speedstep off i did however lap the heatsink down so it was smooth and I'm running a single viper fan

Rated 5 out of 5 by from Easy water cooler I wanted something easy to use, and water cooling, on my first build and this was just perfect. Had it put together in minutes and attached to the case and CPU. Seems to be well made and comes with everything needed to fit the current Intel and AMD processors. I chose this one as it has a square CPU interface and not a round one. CPU's are square so it made sense. Had it running for a few weeks now and its very quiet. It also keeps the processor at a good temp even when its working hard. I'm glad I bough this one and would recommend.
