5 out of 5 eggsAwsome!!!

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

Pros: Price, Quality

Cons: I can't think of any

Other Thoughts: This has been a great liquid cooler so far, setup was the same as others and I have yet to have any issues. I went through 2 corsair H100i within 3 months and this one is still going strong.

2 out of 5 eggsWorked for a while then pump stopped working.

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

Pros: Works "well" while being used, low sound and low temperatures.

Cons: Have shipped two of these in the past year due to the pump not working.

Maybe I just get bad ones?

But won't be using the warranty again on this one.

5 out of 5 eggsWorks great

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

Pros: Keeps cpu very cool. this is over kill for what I use it for. But Pay for it now or pay for it latter. Good insurance in my option. Worth every cent.

Cons: not to hard to install but a little harder than simple plug and play.

4 out of 5 eggsOk 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 to install
Low price

Cons: Fan doesn't move enough air

Other Thoughts: I purchased this cooler as a temporary solution to cool my 4790K cpu until i build my own cooling loop later this year. When I installed the it fan ran ok but it just did not pull enough air through the radiator. I switched to the original fan the Antec case came with and the airflow through the radiator increased lowering my cpu temp 10 degrees when overclock to 4.5 GHz. I don't think it will cool enough to run my cpu at a higher GHz but I would buy this cooler again for temporary use or if i was not going to overclock.

4 out of 5 eggsRivals Budget Air Coolers

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

Pros: -Convenient 120mm size
-Comes with all hardware
-Easy install

Cons: -Instructions severely lacking
-Hardware for radiator & fan mount not long enough

Other Thoughts: I bought this to replace the CM Hyper TX3 I have on my AMD A10-7850k. Once I got it installed it does keep it much cooler that the TX3 did, with the thermal margin not dropping below 40* with Prime running in the hottest config. As far as the mounting hardware goes, it might vary depend on your case... but my Thermaltake Core V1 has a slight bend on the mounting points on the chassis creating a few mm gap, so the screws that came with it were not long enough to mount the radiator on either side of the chassis. A quick run to the hardware store for some 6-32 hardware got it mounted up just fine. The pump runs quiet, with just a little hum so I can barely hear it running, but the blue LED also lets you know its good to go.

1 out of 5 eggsColler Master Seidon 120v

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

Pros: It works great for the first month

Cons: I thought i was getting a quality product ( after reading all the reviews) but the fact is i cant brows the internet without my pc heating up to 120 degrees F let alone do anything else. I have had this for about 3 1/2 months and it just wont work right iv installed it several times, reapplied thermal paste and gone through everything and she still runs hot. I even applied a stock heat sync and i got better temps then what im getting from a water cooled radiator system. I am very disappointed in this product

Manufacturer Response:

Hello Zeralda S,

We apologize for the trouble that you are experiencing with the Cooler Master 120v. It is possible that the pump is defective and not circulating the water so may be why you are recieving high CPU temperatures.

The Seidon 120v comes with a 2 year warranty so please contact us for a replacement.

4 out of 5 eggsKeeps your PC Cool, But Fan is Loud if left on

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

Pros: -Usable for any processor,
-Comes with decent amount of Thermal Compound
-Easy install (Dependent on where you put it in position

Cons: -Stiff tubes when comes out of box
-Try to not to bend the tubes
-Fan included is Loud when run at high speed

Other Thoughts: Radiator is able to be used for top mounting mostly, but can be used for back mounting inside case, be careful on where you are suppose to it.

5 out of 5 eggsBETTER than AIR

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

Pros: In my opinion this cooler was design for processor the AMD FX-8350. It works extremely well for my setup

Cons: none

Other Thoughts: If you are getting processor heat causing computer shut downs and you are a gamer. Get a full tower case with a lot on 200mm case fans to push the heat air from your case, and this cooler. What a huge difference for me. Here are a few of my computer peripherals.
AMD fx-8350 processor
asus m5a99fx evo r2.0 mb
EVGA SuperNOVA 1300 G2 ps
AMD PERF ED 8GB 1600MT/S CL8 (4X4GB) PC3-12800
EVGA GeForce GTX 970 SSC in SLI
