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.

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.

Do you have you a question about the Master Cooler Seidon 240V all in one Blue LED CPU Liquid Cooling Kit?

Q: Hey there,I'm really interested to buy this cooler from you guys,But will it fit inside my Corsair Carbide 03 spec,MSI 970 gaming mobo,Thanks for your time.

There's very little clearance along the top of the case to mount a radiator and fans correctly, I don't think it will fit either at the top or front. I'd recommend a single fan 12cm watercooler for that case. -Danlevan

This AIO is quite good in terms of performance, at least to me: i7 6700K @ 4.5GHz (core+ring) idle: 20-30 deg C 1 hour AIDA64 FPU stress: 58-61 deg C The main downside is the difficulty in installation. I almost damaged my motherboard. Better to install the water pump before you fit your mobo into your lovely case.
