Ahhh bigger. We like bigger. No matter what it is, when it comes to PC hardware, bigger is nearly universally better. Bigger hard-drives give more space. Bigger RAM gives improved application performance. Bigger heatsinks gives better cooling.The same is true of radiators. A bigger radiator in your house produces more heat. A bigger radiator in your water-cooling loop gives lower temperatures.Of course there are some limitations to size. You'd never fit a Noctua NHD14 into a HTPC case for example.As you can probably tell from the cooling theme of the introduction, todays review is of something that is bigger, and therefore hopefully improved, version of a CPU Cooler we've previously tested here at OC3D.When we tested the Corsair H50 we found it had a great mounting system and reasonable performance for a self-contained CPU water-cooler. However it just didn't have either the rad-size or pricing to be a sensible alternative to a high-end heat-pipe tower style air cooler.Corsair have have been busy beavering away in their labs and have produced the H70. So before we take a look at this big brother to the H50, let's grab the features off of the Corsair website.
