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.
Thermalright is an elite design house that manufactures cooling products for computer components for the best quality and performance your money can buy. In 2002, AMD released its first generation Thunderbird CPU and since then we have been there every step of the way to counter high voltage and high heat with innovative design and highly acclaimed cooling solutions not only for AMD but for Intel as well. One of early well known solutions was the SK-6. With many positive and rave reviews under its belt Thermalright bolted to the top as the heat sink manufacturer mostly preferred by Overclockers and enthusiasts around the World. To this day, innovation never left our vocabulary as we keep coming up with leading edge designs staying ahead of the competition.
To get the best possible results in terms of cooling efficiency a CPU Air Cooler needs to have a number of things going for it including a large number of aluminum or copper fins (copper however is quite expensive so most manufacturers choose that material to create special edition limited models), as many copper heatpipes needed to make use of that specific number of fins and a good high-RPM fan or set of fans to provide plenty of air moving through the fins. So if a company was to skip on the fans entirely to release a passive noiseless CPU Cooler naturally they would need to make up for that with something else and the easiest solution is to provide a larger surface area which means either more or simply larger fins. That's pretty much the path Thermalright chose to take with the HR22 and the result is really massive making it perhaps the largest single heatsink tower model in the market currently. We have seen a few similar attempts in the past but none really managed to impress us in passive mode so let's see if the HR22 is good enough to be the exception.
