5 out of 5 eggsCooler Master Seidon doesn't dissapoint

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

Pros: *Great fit
*Stays cool
*Great Price

Cons: None

Other Thoughts: Great for the new X99 Build if your using the new Haswell-E to mildly overclock, if your doing hardcore overclocking then i would suggest a custom loop or bigger AIO.

3 out of 5 eggsWorth the money

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

Pros: Inexpensive! Especially when you catch it on sale right here!
Quiet
Quality PWM Fan
Comes with thermal paste

Cons: Instructions are terrible
Could not mount without some ingenuity
Somewhat rigid tubing

Other Thoughts: I have had many water cooling systems in the past, this was my first AIO though. For the price, I couldn't resist. I was plagued with the stock annoying me whenever I played a game or something somewhat intense was going on.

First off, the instruction were pretty bad, if an hour or two were spent writing step by step instructions, I think that would be helpful for many people installing it. As I am a guy, I don't need them!

The backing plate did not sit flush on the back of my motherboard, and even looked like it may bridge some soldering points. This maybe a nuance of my particular motherboard, but I can not imagine it is the only one with this issue. I remedied this by using some of the foam that was in the box as a non-conductive buffer between the plate and the motherboard. I had to cut out a small chunk of the foam to fit around a chip on the back.

Due to the foam, it was difficult to thread the nuts on the mounting plate. I slightly bent the mounting bracket to make it all fit. One thing that would be helpful is some sort of torque idea on the nuts. I tightened them quite lightly as to not damage my motherboard. Once that was on, mounting the radiator was cumbersome but not too difficult. I had to pull the wire out of the supplied fan so it would reach a motherboard header. It only reached a system fan connector, not the CPU header. I did install this in a mini itx case, so the tubing being so rigid made it difficult.

***NOTE*** Make sure the pump is connected to a full power lead, the power should not be throttled in any way.

Fired it up, and I am pleased. My temps dropped significantly!

Before idle: 53C Maxed: 73C
Now idle: 37C Maxed: 50C

This was with the fan at less than 50% of maximum too! I bought this because I wanted it to be quiet, so for those who say it is loud, perhaps you need to adjust your fan settings.

Important system information:

AMD A10-6800K
ASRock FM2A88X-ITX+
Cooler Master Elite 130

I would buy this again, at the sale price I got it for! Now I can play a little more with the overclocking of my APU!

4 out of 5 eggsGreat cooler.

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

Pros: Amazing cooling, overclocked my fx-8320 to 4.5 running under 40C.

Cons: Docking an egg because the fan they supplied was bad. it ran but it was hitting its casing, making racket and slowing down fan speed. Solved this by putting my Delta fan on it (240 CFM)

1 out of 5 eggsVery Disappointed

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

Pros: None

Cons: Could not get this unit installed due to not being able to get the provided equipment to clamp down properly on my Motherboard. When I tried to tighten the screws the posts continually rotated and could not get the unit tightened down. My earlier Cooler Master Hydro unit was much better built and was engineered to be much easier to install. I am sending this back for a refund.

5 out of 5 eggsdoes the job

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

Pros: My server is a lot quieter

Cons: well my cpu temps are about the same when it's working hard but idle is a bit cooler I feel like this cooler is better for lower wattage cpu's I'm thinking 100 watts or lower

Other Thoughts: I'm running an older amd 965 c3 but its still 125w TDP slight oc @ 3.6

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

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.
