Cooler Master Seidon 240V AIO CPU Cooler

The Seidon 240V is the latest AIO watercooler that boasts an excellent value for performance. The compact 240mm radiator fits in virtually every case. Thanks to dual Silencio fans designed for silence, Seidon can unleash a powerful cooling storm at your command and keep it silent. Durable FEP Tubing provides the advantages of nearly no moisture absorption, high thermal stability and high pressure tolerance which all contribute to a long operating life.

The Optimal Pump and Water Block
The optimal pump and water block guarantees the best water flow and system performance. Elegant Blue LED illumination on the top of water block.

New Cold Plate Technology
Factory filled with coolant then sealed and pressure tested - requires zero maintenance for years. Precision machined Microchannels maximize the water contact surface too quickly dissipate heat.The FEP tubing allows maximum, unrestricted waterflow and decreased evaporation rate for greater durability.

Tool-free Universal Mounting System
Compatible with all available Intel and AMD platform, include latest Intel LGA 2011 and AM3+

Silent Fan Technology
Dual Silencio fans to increase the performance of heat dissipation.

Reduced Noise and Power Output
PWM fans put out signal impulses that cause clicking noises and deformations within the fan. But Cooler Master's exclusive Silent Driver IC slows down the signal rate, suppressing the PWM switching sound. This results in an ultra-quiet 11 dB and low power current that clocks in at 0.6w(12V, 0.05A), not only making it the quieter choice but also helping you save on your energy bill.

Quality and Reliability
The Loop Dynamic Bearing (LDB) is a rigid and abrasion resistant compound that reduces vibrations, noise, and increases life expectancy to 160,000 hours. The self-lubricating and IP6X dustproofing design protects the bearing and keeps it operating smoothly, ensuring a new system will likely be long obsolete by the time these fans expire.

Great Product

I've had one now for 5 months I think and its been great. It's not the quietest out there but remember you're paying £59 vs £130 or so for the top of the range. When Idling its super quiet, only when the fan ramps up the noise picks up as you'd expect.

I'm running a Skylake i5 6600k overclocked to 4650mhz and it sits around 65c under stress. I probably could push it further but I'm not a OCing expert so I'll leave it there.

Just wanted to put up a quick review for those looking at getting a good air cooler and wondering if its worth considering an AIO solution like this instead as the prices are not far off, I'd say do it if the case fits the 240 rad.

Excellent AIO, great cooling but awkard mounting

I thought the Raijintek Triton a great cooler for the money (apart from the leaking!) but I find the Seidon 240V even better at keeping my X5650 @ 4.4Ghz cool.
I think the first reviewer of this product might have a faulty one as I can't hear the pump over my system fans.
I bought this on the strength of a few online reviews that shows it to be be an effective cooler and I absolutely agree.
They also mention the awkward mounting system and this is also true. For the sake of saving pennies on four nuts to hold the bracket poles in place, Cooler Master have made the process harder and longer than it should be.
However, once fitted, you'll appreciate the cooling and all is forgiven. I ran Prime 95 for twenty minutes and the highest it got was 65C. The same test on my old Triton reached around 70C. Utter bargain!

Not really worth the money, loud and noisy, poor performance and fiddly mounting brackets.

This was bought for my friend's Skylake build (6700k, 16gb ram, gtx1070, corsair 400c) the installation of the brackets was really fiddly and required two people, one person to hold the bracket in place and someone else to position the pump onto the four screws. The thermal paste was very runny and when inclining the case to get to the mounting bracket it can nearly run off your cpu, so be careful.
There was flex in the bracket so the mounting wasn't as tight as i'd of liked and the temperatures were around 75c underload which is worse than a evo 212 which costs £25. The pump is noisy and overall i just didn't feel happy with the purchase. Also the piping looks dated with the ribbed effect.
