Silent Fan Technology and Dual Silencio Fans

Reduced Noise and Power Output Cooler Master’s incredible Dual Silencio fans help increase the performance of heat dissipation, keeping your system extremely cool. The high-class Silent Driver IC from Cooler Master, decelerates the signal rate, suppressing the PWM switching sound, as OutputPWM fans put out signal impulses that cause clicking sounds and deformations within the fan. 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, superior choice but also helps you save on your energy bill.

Tested to Deliver the Best Cooling Performance

guaranteed unrestricted water flow The Seidon 240V from Cooler Master is designed with efficient and durable FEP tubing, machined Microchannels and new cold plate technology which all contribute to a long operating life.

Quality and Reliability that you can Trust

a smoother running system The Loop Dynamic Bearing (LDB) is a firm and abrasion resistant compound that diminishes vibrations and noise while increasing life expectancy to an impressive 160,000 hours. The self-lubricating and IP6X dust-proofing design guards the bearing and keeps it functioning smoothly, ensuring a new system will likely be long outdated by the time these fans expire.

Rated 5 out of 5 by from Good performance and great value I got this cooler to upgrade my 5 year old pc so it could run recent games. The i5 4670K runnig Intel XTU and stock fan got to 73c under load. With the AIO this dropped to 57c. Overclocking from 3.4GHz to 4.5GHz never got higher than around 62c. I chose this water cooler over an after market air fan as on paper it looked much quieter and the price I paid was very good value. In use I cannot hear the fans at all, even at max load. You can just about hear the pump at idle. At full load you an definitely hear it. It's quieter than the stock fan plus 3 120mm system fans. If you are playing a game the game sounds would probably be more dominant. Besides, how often would you sit listening to your pc maxed out but not doing anything? The brackets hold the pump over the cpu very firmly. The flexible tubing is stiff but I managed to get it all in place. Go gentle with the screws to avoid stripping threads. I made a mistake with measuring my case before making the purchase. There is room at the top for the radiator if you move the optical drive, which is easy. I forgot to allow for the fans which attach to it. My work round was to drill a couple of holes and fit the radiator at the top of the case, inside and the fans attached on top, attached to the radiator outside with the thin mesh between: a pull configuration. It also meant I had to cut some slots and holes in the plastic fins and trim to allow the fans enough room. Not ideal but it works. I run Speedfan on my MSI Z87 G43 motherboard. The fans attach to CPU1 header via the supplied splitter and pump to CPU2. That gives me separate fan profiles for each function: fans and pump. Overall: Recommended

Rated 4 out of 5 by from Good cooler but fans get noisy The cooling is very effective and works well the only down side is the fans get loud when your CPU heats up. On some systems running stock speeds this might never be a problem but if you overclock at all then the sound may be unbearable. I replaced mine with 2 Fractal design pwm case fans which I also purchased from scan. These fans are quieter than the cooler master silencio fans even when maxed out vs the silencio fans on 60% (set in bios). I still use the silencio fans as case fans but they are too loud over 60%

Rated 5 out of 5 by from Very cool. Playing FH4 with AMD A10 Cpu, temp got to 72 degrees with Cooler master T2 Blizzard. Fitted this and it does'nt go past 47 degrees. Excellent. Fans are louder than the other, but now there are two and fitted to the front of a Cooler Master Silencio 452 case. So a little noise is to be expected.

Rated 4 out of 5 by from Unbeatable for the Price Used this to fit onto a [email protected], 1.28v. It performs very well and keeps the cpu around 63c in AIDA and well under 60c while gaming. It was pretty simple and straight forward to fit aside from fixing the pump to the backplate where an extra pair of hands will come in handy. The pump is fairly quiet, but the fans start to get loud if they go over 60%, on the plus side, they never really need to get that high anyway. One issue I had, I overtightened one of the fixing for the pump and in doing so damaged the thread, which meant the pump wasn't being held tightly enough to the cpu, and that obviously meant temps were much high than they should have been. I figured out what had happened though and managed to rethread it and get it fixed on securely. If it wasn't so easy to damage the thread on the fixings I would have given the item 5 stars, as it is, 4.

Rated 2 out of 5 by from Very poor fitment on LGA1151 Bought this as part of an 8700k build. Fitting the rad and fans is very straightforward however the documentation is very unclear regarding orientation of the backplate for LGA1151 as if you positioned it in the indicated orientation in the instructions it hits screws on the back of the CPU socket. Perhaps I was unlucky but my one was giving really bad temperature spikes and I found that the screws had bottomed out without the cooler being tight onto the CPU. I ended up removing it, bending the top bracket mounting lugs in a vice in my workshop and then refitting using AS5 compound after a good clean up, this made a HUGE difference. If you do get one of these make sure its tightening up properly on your processor. To be quite honest given the quality I would honestly spend a bit more and go for a better AIO.

Ryzen upgrade

I'll be upgrading to a Ryzen 5 1600x soon and I was wondering if this will fit the processor and does it come with the required mounting plate for a x370 motherboard?
Asked by: CheekyJ
Apparently not, you need the Ryzen upgrade kit to make it compatible.

Will a Coolermaster Seidon 240V Version 3 All In One AIO Hydro Cooler fit in a NZXT Phantom 530 case

I want to know if the Coolermaster Seidon 240V Version 3 All In One AIO Hydro Cooler will fit in an NZXT Phantom 530 case. I have checked NZXT's site and cant seem to find any info as to the compatibility of this cooler.
Asked by: WH81
Hello there, I have had a look at pictures online of the NZXT Phantom 530 and some pictures display that yes indeed you can fit this radiator inside your case. It will fit at the top of the case. I do not know if the NZXT Phantom 530 comes with 2 pre installed fans on the top but once you have removed them then you have more than enough clearance to fit the radiator with the 2 fans that this product comes with. I have attached a picture that I have found from Google which shows you a white radiator placed on the top inside of the case. This AIO cooler I have installed into a NZXT S340 Razer Limited edition case with no worries and its much smaller in comparison to the NZXT Phantom 530. *note the picture is from Overclockers UK without the watermark but the picture should help you to where the radiator can be installed*
