    Very good cooler, a little annoying that it doesn't come with it's own software so you have to utilize the fan control software of your motherboard or elsewhere. Good packaging however, good product, keeps my CPU cool even when overclocked.

    Decent for the price, but to be honest I think a Hyper 212 Evo will perform just as well or better. The stock fan is loud as you know what! I'm upgrading my cooler soon trust that.

    Very surprised with this cooler. As it is the cheapest AIO on the block, I decided to try it out, wondering if water cooling would help me much. Well, it certainly did. I'm not getting more than 67c under 100% load with my CPU running 5.04GHz, all while the cooler is dead silent! Cooler Master included 8 fan mounts, so I could easily add a fan to make it a push/pull radiator. Love it!

    I was determined to try water cooling, and for $30 the Seidon 120V is solid. +1 star for the $20 rebate. I had to apply more thermal paste than I was accustomed, and it took me three attempts to get the block/paste situated properly. I ended up adding a thick line of compound across the CPU rather than a blob. The pump is the only thing I hear at idle CPU load, and the CPU fan becomes audible under increasing load.

    This kit was very easy to install and the blue LED fan looks great, highly recommend and I still can't believe how cheap this thing is!

    Very underrated product, excellent cooling for the price, I don't know why everyone doesn't just get one of these. Here is a screenshot of my temps without overclocking: https://s28.postimg.org/izymffaal/noctemps.png

    At full speed the pump is loud, but not too bad with other fans at full speed. The radiator is nice and the rad fan is quiet. Haven't had any issues, keeps my 4790 happy all day long.

    Runs a little bit loud but is miles ahead of the stock cooler

    Have no complaints, no need to maintain and you just really install. Keeps CPU (Intel Core i5 6600k) really cool. When gaming and streaming at the same time it keeps the CPU well under 60C.

    Old reliable still getting the job done. Upgrading to the Corsair fans allowed this unit to stretch it's legs. Gonna rock this thing until it fails.
