Cooler Master Seidon 120M was announced for first time in summer 2012 meant to be a cheap AIO water cooling system focused on the regular customers offering good performance working at low noise level and maintenance free setup. Whether these statements are right, we will find out a bit later.
So let’s get started.
Cooler Master Seidon 120M was provided to me in the typical for the company, but a bit bigger carton package painted in black and purple with a full picture of the product on the front panel, some technical information on the back panel and of course the full technical details on the side panel of the box.
It’s a pretty good looking package but after all it is not the major thing to check out about this AIO water cooling system.
After I opened the package I saw the product disassembled and all of the parts placed in nylon bags and inside special compartments inside a paper shaped “bed”.
So, the first thing to notice here was that the product arrives with a lot of additional parts offering a variety of options for Cooler Master Seidon 120M.
The standard package offers:
- Installation and warranty guides
- Mounting brackets needed for installing on Intel platforms including a painted in black backplate
- Mounting brackets needed for installing on AMD platforms including a backplate
- Four screws needed to install the brackets to the waterblock
- Some screws and nuts needed to install the mounting system to the Intel platforms
- 8 long bolts needed to attach the fans to the radiator and install the radiator to the case
- The standard thermal compound provided with all of the CPU coolers from Cooler Master.
- One 120mm Cooler Master Blade Master fan
According to the official technical details the model is sutaible to work with:
- Intel LGA 2011 / 1366 / 1156 / 1155 / 775
- AMD Socket FM1 / AM3+ / AM3 / AM2
Now let’s check the AIO water cooling system itself.
Cooler Master Seidon 120M offers a pretty standard structure with some minor differences compared to every modern premade maintenance-free watercooling offered on the market these days and is made of 4 major components.
1. Cooler Master Seidon 120M offers a waterblock entirely made of one really high quality copper piece with micro channels inside and contact surface with a perfect shape outside and without any roughness, which makes me smile because this predicts really good and trouble-free results. Apart from the good contact surface we have a lot of screws, which by the way are very tight, made to offer safe and maintenance-free operation. Here you can notice the 2 holes on the side of the waterblock and maybe the channel in which the mounting brackets needed to install the waterblock to the motherboard are placed and tightend by 2 screws on each side.
The most important thing for the AIO watercooling systems are the waterblock and the pump and in that case they are combined and hidden behind a black plastic cover with a futuristic design and of course the Cooler Master logo on it. Both of the components are made as one unit to make the product nice and simple to use.
Right above the company logo the plastic is semi-transparent and there is one blue LED beneath it indicating that the AIO system is working.
The powering and the regulation of the pump is done by a very long, sleeved in black 3-pin cable and connector.
2. Next thing to notice is the water tubes making the connection between the radiator and the waterblock. The tubes used in this product are ribbed on the outer side and very flexible so the radiator can be installed on the back or the top panel of every modern case and of course painted in black so they can stay neutral to the colour scheme made inside the case.
3. According to the official information released with Cooler Master Seidon 120M the heat dissipation is done by the radiator with dimensions of 150.3 x 118 x 27 mm, which is very thin and offers the chance to be used with up to two 120mm fans.
The radiator is made entirely of aluminum with improved fin design for minimum air restriction to reduce fan speed and noise and of course it is painted entirely in black.
There is one thing that I see for first time in an AIO water cooling system and this is the tiny filling cap with a warning sticker beneath. So if anybody decided to open this – Don’t do it! You will probably ruin the product since it is factory filled with coolant and then sealed and pressure tested.
4. OK, we have a premade AIO water cooling system offering a good looking and high-tech waterblock, some fancy ribbed tubes and very thin radiator which unfortunately are useless without a good fan to blow the heat out of the radiator and the case accordingly. For Cooler Master Seidon 120M the company is using the very well-known, a bit old but very effective model and that is (drumroll) ….. Blade Master 120mm. Good choice Cooler Master… good choice….
According to the official technical details the Blade Master works in 600 – 2000 revolutions per minute range, providing airflow level of 19.17 ~ 86.15 CFM ± 10%, static pressure of 0.31 ~ 4.16 mm H2O ± 10% and 19 ~ 40 dBA powered and regulated by a very long sleeved in black 4-pin PWM cable and connector.
And this is how the fan looks when installed on the radiator.
If you remember… I talked earlier about a channel on the side part of the water block… A channel needed so the mounting brackets can be placed and screwed to the waterblock. And this is how they look like when installed and ready to be installed to the motherboard.
Is it already time for testing?
Suuuure …. 🙂
To keep the tradition, before I move on to the test results, I would like to describe the system, used for the test:
CPU: AMD Athlon X4 620 at standard frequency of 2612 MHz and overclocked at 3640 MHz (at 1.5V) per core for the tests.
Motherboard: GigaByte 790X-UD3P
Video card: Sapphire 5830 Extreme 1GB DDR5 256bit
Memory: 2 x 2GB Apacer 800 MHz
Hard drive: Kingston SSD SV100S264G
Case: Cooler Master HAF 932
Power supply: Cooler Master Silent Pro 600
Cooler: Cooler Master Seidon 120M
Thermal paste: Gelid GC-Supreme
Fan mounted: The standard 120mm fan – Cooler Master Blade Master 120mm
The tests were conducted in a closed system with:
- 230mm fan on the front panel putting fresh air in and spinning at about 700 rpm
- 230mm fan on the side panel putting fresh air in and spinning at about 700 rpm
- 230mm fan on the top panel taking hot air out and spinning at about 700 rpm.
- Room temperature of about 18 degrees.
I will install Cooler Master Seidon 120M and do tests at default frequency 2612 mHz at idle and stress and at overclocked frequency of 3640 mHz again at idle and stress using just the standard 120mm fan included in the package.
Since my new bench setup has problems with temperature measuring with all of the softwares I’ve decided to use my old platform and do the tests for Cooler Master Seidon 120M.
First thing to do is to remove the standard plastic and metal brackets from the motherboard and install the backplate provided by Cooler Master and just screw the waterblock to the motherboard. Very nice and easy if I don’t count the few times when the radiator hit me just because I wasn’t careful enough :). After the waterblock and the thermal compound were in place I had to put back the motherboard inside the case and fix the fan and the radiator to the case.
Since the mounting can be a bit tricky I had to lay down my case and work like a real tester. And here I got some hits on the head from the radiator.
After I ignored the pain I finished installing the radiator and the whole system looked like that. Beautiful!
If you paid attention to the pictures you probably already know that there is a big clearance for the DIMMS and all of the 4 DIMM slots are available when Cooler Master Seidon 120M is installed.
I believe it is time to check how Cooler Master Seidon 120M performs.
The results from the tests at default frequency 2612MHz are:
The results from the tests at overclocked frequency 3640 MHz are:
All of the test results have been summed up in the following charts:
And the fan speed during the tests:
WOW! Very good Cooler Master…
The tests are finished and now is the time to write my….
- Cooler Master Seidon 120M performance – To be honest I haven’t got much experience with AIO water cooling systems but I have tons of experience with my cpu temperatures and sometimes I even guess the results before I even finish testing. And for Cooler Master Seidon 120M I can say really great performance. The processor was working like a charm without any chance to get overheated. Awesome results beating a lof ot air coolers which I’ve tested before.
- Cooler Master Seidon 120M noise level – here is the tricky part. As I already meantioned the fan used to keep the radiator and the water inside cool is Cooler Master Blade Master 120mm. Very good and powerful model but a bit noisy, which is kinda acceptable when a huge performance is chased. Those results were made with the fan and the pump working at maximum speed for huge performance by sacrificing the silence. Of course when both are automaticly controlled by the motherboard there is almost no noise at all when the system is at idle or a very tiny noise when there is some load on the processor.
- Cooler Master Seidon 120M appearance – Very nice and stylish product entirely in black, which is meant to stay neutral and not ruin the colour scheme of the system. Apart from this it is much smaller than a regular high end CPU air cooler which leaves much more space and it is much easier to work inside the computer.
Before I finish the article I want to say one thing that I see as a disadvantage and that is the powering method. Cooler Master Seidon 120M offers 2 parts that need power which are the water pump and the cooling fan. Unfortunately both of them are with separate cables and require 2 fan connectors from the motherboard. And this is not really nice since every modern case has at least 3 case fans which also require powering connectors. And unfortunately very few of the motherboards offers more than 3-4 fan connectors.
According to my review, I’ve decided that Cooler Master Seidon 120M deserves the following reward:
Official price (MSRP): unknown
Official warranty: 24 months
I thank Cooler Master for the sample.
