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

5 out of 5 eggsGreat Item

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

Pros: works great, fits multiple types of CPU's.

Cons: one screw that holds the copper plat onto the CPU was stripped or something. when tightening it spins once it to a certain tightness, but it holds decently.

Other Thoughts: Overall, i think this is a pretty good Cooler for my CPU. i have a intel i5-2500k overclocked at 4326MHz with the Push-Pull setup and it stays around 20-25C idle, when playing a game like Bioshock infinite it stayed at about 30-40C hardly anything has been able to make it pass 40C unless i used a bench marking program. which it barely stayed on 70C if i remember correctly.
Overall, i love this thing. have never had to worry about overheating my CPU. the radiator MAY make sloshing sounds when starting up the PC but so far from my end seems to be a normal thing just adjusting and such. after being on for a while i don't hear anything.

4 out of 5 eggsWorks great, slightly big

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

Pros: Cools very well

Cons: The radiator top is a little big which caused some fitment issues in my case and the tubes aren't super flexible.

Other Thoughts: Got this on sale with a mail in rebate....though I have yet to receive that yet after a month so far. If/when i get the MIR back it will be cheaper than the evo air coolers, but even if I don't it was worth the investment. CPU stays below room temp even when OC'ed and gaming. Only issues were the tubes aren't very flexible and the radiator top is too tall for proper fitment in my case but I rigged it to work cause I'm fine with ghetto lol.

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

Pros: Very cool

Cons: It would be quiet for a space heater. Make sure your room set-up has it facing away.

5 out of 5 eggsWow

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

Pros: Price...Works better than expected..well made... overclocked Phenom ii 955 to 3600 Mhz idles at 28c never goes over 55c while gaming.

Cons: tubing not very flexible, but that keeps it from kinking.

Other Thoughts: Its not very clear in the instructions but the pump needs to be connected to case fan or sys fan connector running at 100% and the radiator fan connects to cpu fan

3 out of 5 eggsGreat AIO Cooler

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

Pros: Cools my FX6300 with ease even with it overclocked
Comes with second set of long screws for push pull setup

Cons: Super loud fan
Tubes are a bit hard to flex and get in place

Other Thoughts: Replaced the fan with the NZXT Performance fan and it's great. This is the second Cooler Master cooler I bought that had a loud fan so I really hope they fix this in the future.

4 out of 5 eggsHappy with this

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

Pros: Stock cooler was not able to keep my cpu out of the 50c range while gaming and was very loud. Seidon 120v has kept cpu temps at 16 - 29c playimg the same game and is very quiet. Very pleased.

Cons: Pay close attention to the instructions pics. They indicate what types of screws tho use where. Don't over tighten the pump mounting screws, they seem like they want to strip. Don't tighten the fan onto the radiator so tight!!!!! The fan won't move if you do. This is the reason that some people are saying that the fan won't run.

1 out of 5 eggsRMA processing

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

Pros: ???

Cons: Extremely cheap pump. Works only about 1 month.

You do not trust that fake blue LED. Your pump will not work even if blue LED is on.

You can lose entire component by overheat if you use high end CPU.

Other Thoughts: Used it for about 40 days. Just registered CM website in order to process RMA. I may not use it even though they replaced pump. TOO DANGEROUS. I almost lost more than $500 because this.

CPU temp hit 100C and this almost fried my MB. Thanks to my MB that has strict temperature protection. (Asrock Z97 with I7 4790K). LED indicator was on. There were no sign of failure. CAUTION!

If your MB does not have protection function. AVOID this at all cost. You will lose your MB and CPU potentially GPU too.

Manufacturer Response:

Dear Valued Customer,

We apologize for the trouble that you are experiencing with the Seidon 120v. The Seidon 120v does come with a 2 year warranty so please contact us for a replacement cooler.
