Great cooler that ships with the FX-9590. Temps with 9590: <30c idle and <50c load.

For an entry-level AIO cooler, it worked perfectly for my rig. Quickly brings down my CPU temp and you can barely hear it unless it kicks to 75~100% RPM.

I've previously used the Seidon 120V which I think is a bit quieter, but the price was right on this guy. Works flawlessly and keeps temps on my non-overclocked CPU under 50C most of the time.

Excellent for the price, but very firm tubing, difficult to route

A solid cooler from top to bottom, does as advertised and keeps my CPU very cool! I was observing a 35° Celsius idle temperature on my i5-4690K, and that's in a particularly warm setting in my bedroom. It also remained relatively silent, offering very little sound though that can be attributed to proper casing as well.

My only complaint is Cooler Master's negligence on providing courtesy in the package; you should not try to install this without a video handy! In addition, the screws they ship with the cooler to fasten the fan and radiator together are fairly short. In fact, so short that I had to resort to taking a grinder and shaving a good 2mm off the surface of the fan. This did not in any way damage the cooling system altogether, but it was a task I didn't expect to have to go through, especially if the screws could be just a tad bit longer, or if the fans themselves were thinner.

Overall, this is a solid cooler and my gripes about it are highly subjective. At its price point and performance, a must have for any CPU to be cool.

This is my first experience with water cooling and I decided on the Seidon based on reviews and price. The stock CPU cooler was in place temporarily and seemed to do an adequate job even if the fan is a little noisy. The Seidon 120M was fairly easy to install - I mostly followed a Youtube video (found via "cooler master elite 130 water cooling"). The idle CPU temp is ~24C (room temperature) and when running LinX (CPU stress test) it maxxed around 58C per core. Once the test was stopped the temps dropped quickly back to the 20 range.

The Seidon came with a 120mm fan and the 4-wire cable was just long enough for the Gigabyte Z97N-WIFI in this case.

I have the pump wires connected to my System Fan header, and the 120mm fan connected to the CPU header. The pump only has a 3 wire connector so fan control should be 100%. (From what I have read, the pumps should not be under variable speed control.) For the 120mm fan, I have it set to ramp up speed based on CPU temp.

I would recommend Corsair H50i over this, their are functionally similar but Seidon 120M has a blue LED which breaks the red-black theme.

It comes with a cooler master thermal paste so don't brother buying a separate one.
