Cooler Master Seidon 120V Version 3.0 AIO Water Cooling Kit, Quiet, Compact 120mm PWM Fan/Radiator, For Intel & AMD CPUs is rated 2.6 out of 5 by 5.
Rated 1 out of 5 by from Rattling fans and a ticking pump I installed this as part of a new build over Christmas and all seemed well. The temps are nothing to write home about, but it keeps an 8700K @ 4.8GHz under 80 degrees celcius, albeit with a bit of noise. Issues arise when the temps start to ramp up and the fans increase in speed. They make a distinctive rattling sound. I thought I may have a faulty fan, since it comes with two, but I tested them both independently and they both exhibit the same behaviour... they rattle. I decided to amend my fan profiles to avoid the rattle, which means the fans will never increase to their max RPMs as they have to pass through the RPM range where the rattling occurs to get to maximum. This means I'm not really getting the full benefit of the cooler. Unfortunately I then noticed a very fast intermittent ticking noise coming from the pump. It goes nicely silent for a while, and it's bliss, but then there's a sound of air moving in the system and the pump starts making a ticking noise. It doesn't appear to affect the performance of the cooler one bit, but it's a huge irritant when everything else is so quiet. Scan have been kind enough to issue a return for a full refund, so now I must choose a new cooler. Ho hum! At least Scan's service is top-notch.

Rated 3 out of 5 by from easy liquid cooling great bit of kit, my second seidon but the first to be supplied with 2 fans. can be noisy so make sure you use your fan management properlly as by default it was spinning way to fast and therefore producing alot of noise. keeps your cpu cool under load, easy to install and the supplied red led fans produce a good amount of light, move alot of air and are of good quality

Rated 4 out of 5 by from Cool Cooler nice cooler, using on my i5 7600k keeping it @ 30oC idle without a overclock. and between 50-60oC on fully stress. recommend for a cheap water cooler.

Rated 4 out of 5 by from Quiet and efficient Picked this up as a Black Friday deal, wasn't expecting too much as earlier versions have had their issues. So far very pleased, can't hear the pump really at all, the fans are nice and quiet, and it keeps the processor nice and cool with a modest overclock. I found it easy to mount and install. Wasn't trying to build a monster of a system, and this unit is nice and tidy; fits right in.

Rated 1 out of 5 by from terrible after buying this to with my i7600k i was very disapointed. i was reaching temps of 90+ c the fans are very loud and the pump was very fiddly to put on chip as it requires 3 pairs of hands i would definately stay away from this product
