Following the success of the Seidon 120M, COOLER Master introduces an improved CPU water cooler Seidon 240M. It has all the cooling technologies of Seidon 120M applied and has larger radiator up to 240mm. The larger radiator not only sheds more heat but also supports two 120mm fans. The compact design brings it to the masses. Also, the Seidon 240M is designed with zero maintenance and universal CPU socket compatibility.

  • newegg Fantastic cooling performance The durable and powerful water pump helps dissipate heat effectively and maintain temperatures through stable water circulation. The UltraFine Micro channels on the waterblock enlarge the contact surface between cold plate and coolant for more heat transfer. Performance 240mm radiator is designed to dissipate huge heat from overclocked CPU and can accommodate two 120mm PWM fans. The 120mm PWM fan offers a wide RPM range of 600~2400 +/- 10% allowing you to fine tune and balance fan noise and performance.

5 out of 5 eggsPerforming well

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: I have a amd -fx 8320 overclocked to 4.4ghz my temps dropped from high 50's low 60's to high 38-48c temps

Cons: Nothing against the cooler itself, but you can always get cooler !

4 out of 5 eggsaight

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Its very quiet and keeps the pc cool :)
fan rpm can go up to 2400 which is nice
comes with cooler master thermal paste

Cons: the cons are that the amd setup is difficult to install. the screws are too short and have to apply alot of pressure to install it.
when the fan goes over 1400 rpm can get quite loud.

Other Thoughts: its a good budget part and does it job

4 out of 5 eggsGreat Value Cooler

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: - easy install
- very cool temps (compared to 212 evo)
- cheap (got it on sale)
- Custom Design, not outsourced like other brands

Cons: - pump sound is annoying at full speed
- pea/rice grain method may produce poor temps; spread method is the best for this cooler.

Other Thoughts: the fan that this this cooler comes with is so-so. I used a Corsair SP120 (1450 rpm) quiet edition instead, and leave it @ 100%, which outperforms the stock fan with ease.

The PUMP is quiet, but the sound at 100% pump speed (12v) is at just the right pitch to drive anyone insane. I run the pump @ 53% (1475 rpm) to keep noise to a minimum, and after extensive torture testing, the core temps are no different at 53% then with the pump at 100% (2300+ rpm). Lack of documentation suggests lowering voltage on the pump should not be an issue for lifespan, but I won't be held responsible for any problems anyone faces after reading this. if running the pump below 12v is an issue, it should have been in the manual at product launch, not posted afterwards in forums by people pretending to work for Cooler Master.

THERMAL PASTE should be applied with the spread method. The mounting design for this cooler does not apply enough weight/pressure for the pea/rice grain method to spread the paste adequately. I learned this the hard way, after getting poor temperature results for 2 days, and then removing the cooler to find that the thermal paste had not spread very much, and was all blobbed in the center of the cpu. The spread method instantly results in amazing temperatures by comparison. I've installed 100's of cpu heat sinks over decades, and I strongly advise against the rice grain method for this cooler.

Aside from the initial fiddling, this cooler performs very well for a 120mm AIO, and definitely destroys the 212 evo for temps, and trades blows with the NH-D14. but for the thermal paste application, use the spread method; You may get high temperatures with the rice grain method.

2 out of 5 eggsWas ok...

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Was working great, had good cooling and low noise but...

Cons: A fin on the fan broke without any reason after 2 weeks of use. Without anything getting into it. Now I had to buy a H80I as I don't trust the brand anymore. Bottom line, it works great while it works. Maybe I had a bad sample but I can't take any chances.

5 out of 5 eggsGreat price and performance

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: The price is excellent for a AIO cooler, it keeps my A10-7700k in the low 40's during normal operation clocked at 4k mhz.

Cons: Nothing to really complain about.

Other Thoughts: For the price, you cannot really go wrong with this AIO cooler. I have built several Water Cooled computers over the years, for extreme use. If you are folding,benchmarking or keeping 100% cpu this is not the cooler for you.

If you're doing any of the above, you already know this..

5 out of 5 eggsGood Enough

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Was cheap and hasn't failed me. Is also a bit cheaper than the H60 with the same size radiator. Having both I can say they are equal in performance.

Keeps my FX-8320 cool beyond 4.6GHz
Kept my A10-6800K cool past 4.5GHz

Cons: None

Other Thoughts: Make sure to connect the pump to a full 12V line for full flow, and better cooling.

5 out of 5 eggsLove it

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: Easy install, quiet enough, running my FX-6300 Vishera at its stock 3.5ghz and keeps the temp at a steady 30°C under load first time using liquid cooling and it won't be the last!

Cons: none so far will update if something occurs

Pros: Inexpensive, quiet, good cooling.

Cons: Tubes a bit rigid (struggling to find a con).

Other Thoughts: Cooling an AMD A10-5800K without any issues. Easy install.

4 out of 5 eggsGreat Price, Cheap Mounting Screws...

This review is from: Cooler Master Seidon 120V – Compact All-In-One CPU Liquid Water Cooling System with 120mm Radiator and Fan

Pros: easy to install, decent cooling power

Cons: stripped the mounting screw using only my fingers...

Other Thoughts: I was happy that the price was so good! Although my fears were realized when installing I stripped one of the mounting screws.... Keep in mind I used only fingers to tighten it...

Great product but if your going to buy it I recommend you pick up "Cooler Screwpack M4 universal" or something similar. I have one coming to swap out the mounting screw that stripped( I did manager to jerry rig it to work with the stripped screw and I believe it to be working fine, OCing E8400 3ghz to 3.815ghz @ 65'C max temp running Prime95) But I am not comfortable with what happened.
Plus I'll be adding 5 x Phobya Shroud & Decoupler - 120mm and replacing the fan with a Delta QFR1212GHE-PWM 120mm and using the stock fan to pull. (With a custom fan profile with Fan Xpert of course lol). Also I'll be reseating the block with Arctic Silver 5. I'll try to add some pics when finished. Next step is to get a mobo that supports higher then 1600 FBS! lol and the reason I stopped at 3.815ghz FYI
