Cooler Master Seidon 120V

We’ve taken a look at Cooler Master’s  Seidon 120M in the past, and the  Seidon 120V is similar in that it comes with  a 120mm PWM fan that runs as slowly  as 600rpm and as fast as 2,400rpm. The  wide PWM range ensures that the closedloop system will perform well under load  and will function relatively quietly when  the computer is idle. Cooler Master also  provides a second set of screws to let you  attach the 120mm radiator to an existing  120mm fan on your rig, which makes it  easy to create push/pull airflow over the  radiator and improve performance.

The 1.1-inch thick aluminum radiator is  connected to the pump/heatsink unit with  FEP tubing, and we found that the ribbed  hard plastic hoses are nearly impossible to  kink. Another benefit of the FEP tubing,  according to Cooler Master, is that it offers  a high thermal stability and high pressure  tolerance. The pump features a rotation  speed of between 1,400 and 1,600rpm and  operates at 12V. The pump’s noise level is  listed at less than 23dBA.
The included 120mm fan can generate  up to 86.15cfm at its top speed and  produces a listed noise level of 40dBA. At  600rpm, the fan moves air at 19.17cfm and  produces a mere 19dBA. Cooler Master  also lists the fan’s air pressure, which an  important specification because high air  pressure will help to push cool air through  the radiator’s tight spaces. At 2400rpm,  the fan will produce an impressive  4.16mmH20, while the 600rpm speed  delivers an air pressure of 0.31mmH20.
 When you power up your system, a blue  LED in the middle of the pump/heatsink  will light up to indicate that the unit is  operating. The blue LED isn’t too bright,  so it won’t be distracting if you’ve designed  your case’s interior around a different color  scheme. The installation process with the  Seidon 120V was quick and hassle-free, and  Cooler Master provides mounting brackets  that support all major Intel and AMD  socket types.
We tested the Seidon 120M with  Intel’s Core i7-4770K (at stock clocks) and a GIGABYTE GA-Z87X-UP7 TH  motherboard. After 10 minutes of idle use,  the Core i7-4770K delivered a maximum  temperature of 32 C. Next, we pushed the  processor by running POV-Ray 3.7 and  rendering the benchmark on all cores for 10  minutes. We saw a maximum temperature  of 59 C. Finally, we ran four instances of  Prime 95’s Small FFT test for 10 more  minutes. This demanding test produced  a maximum temperature of 65 C. As you  can see, there’s plenty of cooling overhead  to overclock the Core i7-4770K using the  Seidon 120V.
The Seidon 120V is available as a  standalone closed-loop CPU cooler or in a  Cooler Master bundle with the CM 690 II  case. This closed-loop CPU cooler is smartly  designed, and thanks to the PWM fan, the  Seidon 120V will operate quietly in idle and  deliver performance when under load. The  120mm radiator and fan should fit within  most any build.
