Cooler Master Seidon 120M Liquid Cooler (inc. Dual Fan Performance 2x Noctua NF-F12)

We compared the Cooler Master Seidon 120M liquid CPU cooler to Corsair‘s competing model, the H60 2013 edition, the in-depth review of which can be read here. We also included comparison data from 3 mid-range air coolers in Sapphire‘s well-balanced Vapor-X, the enthusiast-loved Thermaltake Frio, and Arctic‘s good value Freezer Xtreme Rev. 2.

Our graphs show actual temperatures of the CPU, not delta temperatures.

Ambient temperature was maintained at 21°C.

Topping our charts alongside the Frio, beating the performance of Corsair's H60 2013 edition on the way, Cooler Master's Seidon 120M liquid CPU cooler is able to offer excellent cooling performance in both stock and overclocked scenarios.

If the chart-topping performance isn't impressive enough, keeping an i5 3570K with a high-voltage overclock below 80°C is another strong achievement.

  1. Super review Luke. I have to order one of these, what a great deal IMO

  2. This is an excellent cooler, the all in ones are hard to beat now. I had a D14 for a while and loved it, but it was so hard to get at anything inside the case it blocked half the motherboard !

    I recentl got a Seidon 120M and it seems to work very nicely. I did add a C/M Turbo Master Mach 1.8 fan on the case side, which didn’t seem to add any perceptible noise. The one change that I would really like would be the ability to raise the water pump speed. With the two fans it seems that increasing the WP volume would be an excellent option. I’ve got a mildly overclocked i7 – 930 and when running a WSE scan, for instance, hte core temp can still rise to as high as 175 F, so a bit more water flow would be nice. I ahve it in a HAF 922 case and there is plenty of room. I’m about to add a 200mm side fan as well as the original rear case fan at the bottom of the case, and things still won’t be crowded

  4. Did you happen to try installing the fan with an exhaust setup? How much difference would you think the performance/results change?

  5. I am thinking of buying a Seidon 240, which you can front mount in a N200 case (both products by Cooler Master). If I do front mount is the air being drawn into the case to cool radiator or am I venting air outwards through the front?

    It seems to me air in through the front would mean the heat from the radiator being directed into the case. But i have never thought of front fans becoming exhausts, so perhaps this is correct.

  6. Hi, I have got this cooling system, but it is incomplete. I would like to but an AMD socket. Has anyone got to sell?
