You've likely seen Sebastian's review of the Corsair H100i in which he failed to provide the exact barometric pressure or even altitude above sea level, merely showing the delta between the base temperature and sound pressure of the room and that of the cooler.  The Tech Report on the other hand offer you insight into the quality of the sound the fan produces as well as the pump.  They also compare the performance to a different cooler, the Aerocool P7-L24 so check out their review. 

If that doesn't satisfy your aesthetic desires there are more reviews below the fold.

"Corsair refreshed its closed-loop liquid coolers earlier this year with the Hydro Pro series. Those 280-mm and 360-mm liquid coolers boasted bold RGB LED lighting and a fresh design, and they turned in good performance, too. We go hands-on with the 240-mm H100i Pro to see whether Corsair can close out the hat trick."
