The updated Hydro Series coolers, the H80i and H100i both feature all new tubing that might not be much more flexible than the previous models but offers improved flow rates.  As well these coolers are now able to be controlled via Corsair's Link technology, allowing you to either set the LED colour displayed or to use it as a real time temperature indicator.  As you would suspect the H100i is the larger of the two units, the H80i being 120 x 38 x 152mm and the H100i measuring 275 x 120mm x  27mm with both supporting up to four fans via the Link software.  [H]ard|OCP saw an improvement from the previous models which you can read about in their full review.

"Corsair updates its aging H80 and H100 performance liquid CPU coolers, with the new H80i and H100i models. Changes include a new cold plate design, smooth outer diameter no-kink tubing designed to further limit evaporation, and newer designed fans claiming better static pressures, and quieter operation."
