3 out of 5 eggsok but not overly impressive

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

Pros: not too hard to install
inexpensive

Cons: tubing is very rigid and not super easy to work with
supplied fan gets loud
not impressed with overall cooling performance

Other Thoughts: I would recommend spending the extra $20 to get the Seidon 120M, it's well worth it for sound levels and cooling performance. If you can fit it I highly recommend the Corsair H80i. At the very least upgrade the fan on this unit

5 out of 5 eggsPerfect for AMD A8

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

Pros: Cools great
Good Price
Reliable
Quite
Comes with good thermal paste

Cons: None

Other Thoughts: Cooled my A8 from 70 degrees down to 37 degrees. Also I even overclocked it and I still get 37 degrees. This is perfect for this processor.

1 out of 5 eggsHorrible build quality

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

Pros: Worker as good as my old Gen 1 H50.

Cons: Where do I begin? The screws that came with the unit are too short to be used. I only managed to get a single rotation of threading before it stripped the thread on the radiator. Luckily I had spares which were longer that worked. The fan is made by a cheaper company, so that is another strike for trying to skimp on production costs.

Ultimately the thing that made me write this review is that this piece of garbage nearly cost me my cpu. 3 months after purchase and the pump died on me. The hot coolant was just trapped in one tube and couldn't cycle through the radiator. I thought maybe it was the power so I tried using an adapter to power the pump. Nope. Tried using a system fan conector. Nope.

Lesson learned. Invest the extra $8 and buy from corsair. Their coolers have yet to let me down in both quality and performance.

3 out of 5 eggsDifficult install

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

Pros: It does cool pretty well.

Cons: Backing plate need some kind of insulated offset for motherboards with surface mounted chips or components on back. The tubing is very stiff. To mount fan and radiator I had to twist 90% and puts a lot of pressure on the connectons.

Other Thoughts: Needs more flexible tubing and adjustable connections.

1 out of 5 eggsI am sure it works for others

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

Pros: It looks nice. I can't attest to the ability to cool a cpu.

Cons: It came with one of the pins to hold the back plate manufactured defectively. It is too long and big for the pin hole in which it is supposed to fit. This is POOR quality control on the part of Cooler master, whose products I have used countless times in the past.

5 out of 5 eggsFixed a really bad heating problem

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

Pros: Cools great (see cooling improvement in comments below). Compact design. Once installed, everything looks neat and tidy. Very quiet.

Cons: The instructions are pretty sparse so it helped me to look at some You Tube videos before I installed it. I have a Cooler Master HAF 922 case so I was a bit peeved that I had to bend a metal tab on the IO back plate in order to install the radiator. I would have expected the CM people would have tested the install on their own cases.

Other Thoughts: I have a I7 920 cpu in a PC I build a while back. Over time, I noticed that the fans seemed to be very noisy. Recently, I started getting messages saying the cpu was overheating. And more recently, the PC started shutting itself down. When I got around to measuring the temperature using HWMonitor, the core temperatures were running from a minimum of 50 C to 100 C (same temp as boiling water). From what I have read, the cpu would not get any hotter because it will throttle itself down when the temperature reached 100.

After installation of the CM Seidon 120V, my PC’s temperature is 37 C when idle and the absolute maximum temp I have seen was 50 C. Mission accomplished.

I will also attest to the fact that the I7 920 cpu is one robust chip!

5 out of 5 eggsI love it!

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

Pros: It keeps my A10-6800K at 39 degrees Celsius when idle. Something no other cooler could do for me. The processor just runs hot and there's nothing I could do to keep it from reaching 50+ degrees when idle. It looks great, especially in the push-pull configuration I have it set in. Also, good price.

Cons: Hoses are a bit rigid. This made installation somewhat of a pain. But once you get the first couple of thumbscrews on the corners, it becomes much easier to handle.

Other Thoughts: So far it's a wonderful water cooler for the price. I'm sure there are better and more efficient ones out there, but for the price it can't be beat.

4 out of 5 eggsSome things YOU (consumer) should know...

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

Pros: This product circulates cold air into your rig, and circulates water to the CPU. Playing planet side and other games that require a lot of CPU run Amazing. It is very quiet and keeps the PC cool.

Cons: This thing is massive. Make sure you have enough room on the back or top of your PC in order to install it. I was able to rig mine to fit it. The installation was not what I expected either. It requires the removal of the mother board and re-installation of it. Nothing that requires complete installation of your PC.

Other Thoughts: If you are ok with taking apart your PC this product is fine. I give it 4 stars because the installation was not what I had in mind. The fan is massive. FYI.

5 out of 5 eggs

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

Pros: > CPU hasn't reached 50C
> Pump is quiet after it gets the coolant cycling through the system
> Helped cut down on temps inside the case

Cons: > Tubes are a bit rigid but it doesn't take much to actually force to manipulate them.
> Used one of my Corsair 120AF quiet edition fan over the stock fan, the screws used to mount the fan + radiator to the top of my HAF Stacker 935 where barely long enough, though the fans are similar in dimensions.

these aren't big enough deal to me to take an egg away.
