I'm running an AMD FX-8350 which my system has kindly overclocked to 4.3ghz within a NZXT H230 case. The case has one 120mm intake fan at the front and a single 120mm rear exhaust fan. The reason for buying this Cooler Master Seidon was because the stock CPU cooler on the AMD was very loud and was struggling to keep cool under stress. I installed the Cooler Master using a push/pull setup, the radiator up against the exhaust fan and the supplied Cooler Master fan the other side of the radiator. After some fine tuning using the software SpeedFan I think I can provide some thoughts on the performance of this liquid cooler.

At 100% it can be loud, not overly loud but loud enough. Luckily though by using SpeedFan my PC now idles at between 30-40 degrees depending on room temp at 60% RPM. At 60% you can't really hear it. I've adjusted it so when the temp increases so does the fan, so unless I'm full loading it which would be pretty hard to do for the average Joe the fan shouldn't become that noisy. However, during full load using Prime95 the temp after 5 minutes was at 65 degrees... I was expecting a lower temp to be honest.

You should take these findings with a pinch of salt though as everyones setup is different. Maybe if I had more case fans the temps would be lower or if my CPU wasn't that little bit overclocked. Overall, comparing to the stock cooler, this is better. Is it £35 better though? I'm not so sure.

i get nice low temperatures in my Cooler Master elite 130, but the included fan 'chirps' at low revs and the pump buzzes at 12v.

The fan was easily swapped out for a near silent Arctic.

I was able to track down some of that pump noise to the hard pipes touching the DVD drive, which was remedied with a larger zip-tie to gently pull the pipes away from other surfaces. I attempted to use an in-line resistor adapter on the pump, but the light on the pump flickered to indicate that it wasn't running continuously and temperatures rocketed! I also tried a 4-pin PWM y-connector so that the fan gives revs feedback and both the fan and pump are able to be controlled from the same header. No change.

The pump is audible across a quiet room. A real shame.

Cooler Master Seidon is entry model in water cooling system which comes together with radiator and replaceable 120mm fan.

Given its simplicity and attractive price this is great device for those who want to try water cooling to find out whether it's something that you like before purchasing more serious water system.

The System is factory sealed and fully tested therefore beside plugging radiator fan plug into CPU fan port and pump into SYS fan port user doesn’t have to do anything or trouble with maintenance. Seidon provides nicely designed blue LED light which indicates is system working or not and wide range of rotation speed enables user to fine tune its noise.

Because of all mentioned features I can recommend Seidon as good solution for all-in-one water cooling system which given its performance and price would be great solution for all people on budget who want to finally try this type of case cooling.

I just purchased this unit as my old air cooled unit was not cutting it anymore. I am currently running a AMD phenom II X4 965 processor, with 8gb Gskillz ram, 1gb ddr5 EVGA Geforce GTX 650 graphics card, Corsair Builder Series CX 600 Watt, GIGABYTE GA-78LMT-USB3 Motherboard. My old air cooled unit (Cooler Master Hyper 212 EVO) was not doing a good job of cooling the CPU effectively so I thought a upgrade was necessary. I looked around for a while but could not find a cheap air cooled unit that would be good enough to keep my CPU cool. SO even though there was no reviews for this I thought for the price I could give it a go.

Well I have to say that I am really impressed with the unit. It came very nicely packaged with all the attachments for either a AMD or Intel CPU. The cooler was a bit tricky to install (only because its my first water-cooled unit) but this is my fault as I did not read the installation instructions. But eventually gave in a read them, after that the install wasn't that difficult even though my case has no water-cooling capability.
So if this is your first water-cooled unit then read the instructions you will save a lot of time.
In the end I had to front mount the cooler and it works brilliant, it gets a lot of cool air from the front and the unit only really gets warm when I am either video editing or gaming.

As for the cooling, this unit is brilliant it really is keeping the CPU cool, unfortunately I don't know how to access the CPU temp to tell you how much of an effect this cooler has but for the first time cool air exits the PC case instead of very warm air.

Now to the only downside, that is the noise.

Very good cooler the original fan was noisy and rubbish but I replaced it with a pair corsair SP120 high performance fans and it dropped my CPU temp by 10 degrees I’m using a FX8350 overclocked to 4.8 and it never goes higher than 56 degrees using prime95 for 3 hours in a fairly warm room.
