[M] Corsair Hydro H100 CPU Cooler Review
 

One of the main remarks we had when testing all the different all in one cooling solutions was the size of the radiator, which limited the heat dissipation. Secondly the modern units generate a fair amount of noise, if it's user opted for maximum cooling capacity. A bigger radiator increases the cooling surface, thus logically should aid in lowering the processor temps. Another big plus is that it allows for more fans to be used, which can spin slower and yet have the same or better cooling capacity then it's single or dual 120mm fan solutions. A while ago Corsair bundled forces with CoolIT, to manufacture it's latest generation of Hydro coolers. And the feedback from it's numerous users resulted finally in a 240mm rad version baptized the Hydro 100.
