Asus showcases its CoolTech coolers with a demonstration video.
Asus has released a demonstration video on its CoolTech coolers that debuted on the GTX 670 DirectCU Mini, which is able to displace more air towards the bottom at lower fan speeds than the reference cooler. The CoolTech cooler consists of a smaller ring, which sucks the air inwards, after which it is propelled outwards by the large blades. This keeps colder air trapped in the heatsink for a longer period of time, thus cooling the aluminum fins better.
