5 out of 5 eggsPretty Cool (Get it?)

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

Pros: I've had this cooler for a couple of months now, and it's worked flawlessly. It didn't leak, it's quiet, and best of all it keeps my processor very cooled. Before I got a dedicated GPU, I used the A10 6800K APU as both a GPU and CPU, and without this liquid cooler it would get very, very hot. But with it, it stayed idled at ~30C, and during gameplay it would rise to about 40-50C.

Cons: None I can think of.

Other Thoughts: Nice cooler, nice price, stays quiet even when it's working hard.

4 out of 5 eggsbetter than stock and priced right.

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

Pros: Small, easy to fit into almost any system.
Inexpensive.
Quieter than the stock cooler/fan.

Cons: I don't really see my temperatures improved from the stock cooler. I realize that in bios, the motherboard runs its components at high, but the temps start at about 40'ish and creep up to 65?
Thats when the fan kicks in full speed. In windows, it seems to work fine, but again, can't really measure it having better cooling power.
Only came with one fan for a push method, reviews show an improvement with a push/pull so I may add another fan and see what that does.

Other Thoughts: I did realize that my psu was kicking on high at times, ordered another since it was pretty loud when it did. Waiting for it to come in, hopefully it was just an issue with the cheap psu. but either way, not blown away by this cooler.

Rating it 4 eggs due to the price including the rebate, was very affordable and its a lot quieter than the stock fan.

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

Pros: I was Looking for a low-end All-In-One Closed CPU Cooler vs A HeatSink and well it does what it says.

Cons: Terrible Whining Noise Well My Mother Board Ran The Pump At Different RPM's !

Other Thoughts: Goes Nicely with My Color Scheme & Cooler Master Case ! :D

3 out of 5 eggsGood Cooling

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

Pros: Great for gaming and high use.

Cons: Problems with installation in some midsize cases.

Other Thoughts: You might have some installation issues with this cooler in some midsize cases. I ran into issues installing the radiator fan unit in my case, had to drill new holes to mount in case, also if your case has a door mount fan you may need to relocate it, I had to mount my outside of my case.

5 out of 5 eggsPretty wonderful

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

Pros: The build of it is really nice, im using it on my AMD FX 6300 and it's keeping it pretty cooled down!

Overall, it's really great, dropped my temps on idle from 45c all the way down to 24-26c! while using cinebench, the temps never went past 39c!

Cons: the tubes on the water block are sturdy, so it is kind of difficult to hold the block down(when the radiator is installed i mean), so make sure you install the block first lol

Another thing you should note, the radiator itself is larger than 120mm, so make sure you have room in the fan slots otherwise you're going to have problems, i "rigged" mine to the case by installing the screws into the wrong holes so, make sure you check your case before you buy this!

Other Thoughts: This is meant for an I5 4690k which has yet to be released and arrive, so temporarily im using it on my current build:

AMD FX 6300 @ 3.5GHz-3.8GHz
Gigabyte 990FX Motherboard
Zotac AMP! Edition GTX 760 10% OC
Rosewill Green Series 630W PSU
ThermalTake V3 AMD Edition

5 out of 5 eggsIt's okay for AMD FX-8350

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 I used a guy MOZIE MAX, on (Youtude) about 19:56 minute, he give good thorough instructions.

Cons: none

Other Thoughts: Before on fan cooling low was between idle 38c and 44c under load was 65c and 78c computer use to shut down because of the high temperature. Now with the cooler master 120v low between 30c and 35c underload 44c to 49c no computer shut down anymore. All was on the Asus MB M5A99X EVO R2.0 A1 auto OC @ 4400 mhz

5 out of 5 eggsBUY IT!

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 is not too loud, and keeps my cpu nice and cool. My computer was constantly overheating while gaming cause of my old stock fan, but with this I haven't gone above 55 c.

Cons: Was a bit of a pain to install but works great! (This may have been a issue with my case that others might not come across)

Other Thoughts: I didn't use the thermal compound that came with this cooler so I can't comment on how good the thermal paste this comes with is.

Also check your case make sure you have room for a 120mm fan

5 out of 5 eggsPretty great

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

Pros: Even though i haven't used it just yet(waiting for my 4690k >_>), it looks like a pretty solid build. once i get the new processor, i'll be able to give a full review.

Cons: None!

Other Thoughts: This will actually be the first time i will ever build a system with a waterblock. but i hope everything goes well!

3 out of 5 eggsAverage

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

Pros: Cheap
Effective
Quality - so so
Fast shipping
Idle was 22 C
Max was 45 C

Cons: -Bad side is the rigid tube, making it hard for me to install by myself
-Back plate is amd and intel design combine, hard to put it in behind the motherboard.
The method to secure the Screw were loose, so it was hard for me to adjust the cooler into the screw
-Lastly the radiator send to me have some bend, and ding inside the metal, some different color were on it too.
However it the cheapest for water cooling so not much can be say.

Other Thoughts: AMD A10 6800K 4.3 Ghz
