5 out of 5 eggsWorks as advertised

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: It works as advertised; keeps CPU temps at reasonable levels (NOTE: I am not OC'ing).
Straight-forward installation (HINT: spend the time to watch a couple of YouTube videos showing how to install; it will help tremendously with installation because the instructions are not the greatest)

Cons: None except for the instructions being a bit lacking.

Other Thoughts: Config:

1 out of 5 eggsCooler Master customer service is a joke

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: None so far

Cons: My equipment was missing the motherboard standoffs. For some reason, Cooler Master tech support is unable to tell me the height of the standoffs so I can get replacements. They are also not able to ship the parts in a timely fashion, though their rep keeps assuring me they'll be sent "tomorrow."

Other Thoughts: Never bought a cooler master product before and thanks to my experiences I shan't be in the future.

2 out of 5 eggsCools down the CPU, but gets noisy....

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: It is quiet when using a windows application.

Cons: Very Noisy when playing a game! The pump makes a rattling noise, like a HDD, but much louder.

Other Thoughts: Has been doing that since I installed it more than a year ago, it is getting worst. I have to open the computer and shake the hoses for the noise to go away.

1 out of 5 eggsFirst liquid cool

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: Good and cool easy install

Cons: -Bought 9-21-15 and as of right now I am on my laptop and I have greenish colored coolant from the cooler all over my graphics card. Luckily I noticed my fan speeds were going higher than normal so HOPEFULLY nothing in my system is fragged. Starting the process to attempt to get this fixed or resolved will update as process continues. NOT HAPPY AT ALL with quality as it is LEAKING all over my gpahics card and motherboard. Would give 0 eggs but it wont let me.

Other Thoughts: UPDATE If customer service and a quality product is what you are looking for do not buy from Cooler Master. 11 Days after they notified me they received the defective product I finally called them. They inform me they do NOT have any coolers to send me and want to refund my money. When asked why they hadn't contacted me they gave me the old "we were just calling" line. Basically I feel they lied 2 times at least in this one call. To say you have NO cooler products and then they were "just getting to calling me". IMO They had me waste my 15 bucks shipping it to them and decided its better business to just refund than to pay to ship me a new product. Needless to say I will NEVER buy another cooler master product and suggest heavily the same to my friends. From shipping time to them until now has been almost 3 weeks and now I have to find and order a new cooler pay shipping on that also and the time it takes to get it here. So not only will my computer be down for total about a MONTH it will actually cost me prob an extra 30 bucks in just shipping alone due to their low quality product and what they call "customer service".

5 out of 5 eggsGreat Value, cool & quiet.

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: -Easy installation
-Extremely quiet operation
-Excellent cooling, my i5-6600k idles around 15c and 28c while gaming

Cons: -Hoses are a little stiff, just consider where you're going to mount the rad and which way it will be facing before bolting things in place as you may need to flip it around to get the hoses to good place.
-Mine came with a couple of the fins bent slightly on the radiator, didn't imagine it would affect the cooling very much so it wasn't worth trying to RMA the product. So far the cooling doesn't seem to be impacted.

5 out of 5 eggsGreat Product

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: Easy to install, no need to worry about checking the water lvl (at least for a couple of years). It also gives it a nice look inside my computer case.

Cons: I can't find any real answer on how long these type of AIO coolers go for before needing replacement or refill.

Other Thoughts: AIO water coolers are nice for first timers who want to dip their toes into water cooling. I expect this cooler to last me at least a few years so I'll be saving to buy a real custom water cooling kit.

5 out of 5 eggsGreat Cooler

This review is from: Cooler Master Seidon 240M - All-In-One CPU Liquid Water Cooling System with 240mm Radiator and 2 Fans

Pros: Install is a breeze and keeps your cpu ice cold.

Cons: The mounting screws for the radiator are too short. Not enough to knock an egg off over, but it should be really nice if they were longer to ensure a truly proper mount.
