It may not seem like it, but it has now been over a year since Corsair released their cutting edge H60i and H100i All In One CPU water coolers. Now it's time for an update as the Hydro H75 and H105 are being rolled out.

In many ways the H60i and H100i are still considered among the best solutions available in their respective categories so some may be wondering why they?re being phased out. The answer to tthat is simple: competition breeds innovation. Despite combining a straightforward installation process, user friendly software and excellent -for their class - cooling potential, other companies homed in on the 120mm form factor. Now that market has become exceedingly crowded with everyone from Cooler Master to Silverstone to Antec releasing their own unique designs which typically surpass H60i and H100i in both performance and ease of use.

With such hungry competition methodically eating away at their foothold on the market, it comes as no surprise to see Corsair once again turning their attention back to single and dual 120mm designs. To do this, they are once again looking towards Asetek as their OEM of choice for the H75 and H105. This means we will see many things in common with the H55, H90 and H110. Unfortunately, since Asetek is being used here, these new units lack the ?I? suffix which denotes compatibility with Corsair's LINK application. This means the H75 and H105 will have to rely upon motherboard-based inputs for fan speed control rather than using a convenient Windows centric hub-based design.
