If i had to pick a single thing that it's quite obvious that all consumers including myself would like to have that is a completely silent system however especially for overclockers and perhaps even serious gamers that’s not really possible. Of course technology keeps evolving and with it so does everything else so to be completely fair we have come a long way since even just a decade ago but we've still to reach a point where we can have powerful whisper-quiet systems (at least not without spending a respectable amount of cash in the process). Tower CPU Coolers have been around for many years now but with just a few exceptions most of them use one or more high RPM fans to increase their cooling efficiency. Thermalright is not one of the leading CPU Cooler manufacturers over a decade now for no reason at all so they know very well what steps they need to take and in what areas they need to focus in order to release a high performance solution and the latest HR22 is the result of all their combined experience.
