Cooler Master Seidon 120V Liquid CPU Cooler Review
Test Setup and Temperature Benchmarks
Two test systems were employed here to give a look at what you might expect from a current-gen AMD and Intel CPU. With only higher end parts to test, the model numbers won’t be consistent with the budget build idea. Obviously a $500 PC isn’t going to be build around a $320 Core i7 4770K processor, but it is actually possible to build around AMD’s $185 high-end 7850K APU (if no discrete GPU is used). Regardless, the results will still show these coolers’ differences.

Temperature testing was done at both stock and overclocked loads, and measurements were made using RealTemp and HWMonitor. The room temps were a constant 18 C. For load temps Prime95 was used, with the max stress torture test run for a minimum of 10 minutes before the readings were taken.
Temperature Benchmarks - AMD
The Seidon 120V was very impressive for a budget liquid cooler here, keeping the 7850K at only 40 C at a full load. The Hyper 212 EVO was right behind it at just 41 C at load. The stock cooler’s temps are not particularly impressive, as one might expect, but not bad – though the benefit of aftermarket cooling can clearly be seen here with the 13-14 degree decrease in temps with the Cooler Master offerings.
With the overclocked workload the Seidon 120V again leads the 212 EVO by just 1 degree C, and both coolers saw temps rise by 10 C over stock clocks. Excellent considering that 1.4V was required to keep this 4.40GHz overclock stable. The stock AMD cooler managed to keep the overclocked APU from overheating, but at 65 C it was pushing a lot of warm air down against the power delivery and memory on the motherboard.
Temperature Benchmarks - Intel
The 120V and Hyper 212 were pretty evenly matched with the stock 4770K, but the Seidon 120V managed lower load temps by 2 C. The results from the stock Intel cooler started off looking promising…and the temps kept climbing and climbing under load. 82 C is not exactly acceptable from a stock workload, though in Intel’s defense Prime95 is pegging the Haswell CPU at 100% on each core. Much better results were possible with the Intel cooler manually set to 100% fan speed, which lowered the temps a full 10 C to 72 C under load. This was not a typical situation, as the PWM fan is not going to reach 100% by default, so the PWM result was given on the chart.
The Hyper 212 EVO comes out on top here at the 4.50GHz OC load, and it's a good result for both aftermarket coolers given the punishing workload of the test and the hefty overclock on this Haswell CPU.
Note: There is no result for the Intel stock cooler here after the poor showing in the stock frequency test, so this 4.50GHz overclock was not attempted with Intel’s default solution.
