TPU came across details of ASUS' GeForce GTX 670 DirectCU Mini at Swedish tech site SweClockers. This new card is a 170mm long version of the GeForce GTX 670, it's expected to be launched in April. The card's base clock is said to be 26MHz higher than the reference model.
The main heatsink appears to be a combination of an aluminum base plate covering the memory chip and VRM, a copper vapor-chamber plate over the GPU, and a radially-projecting aluminum fin array. The contraption is ventilated by a fan unlike anything we've ever seen. Its impeller appears to be a hybrid between conventional top-flow fan, and lateral-flow blower. While ASUS won't tinker with the 6.00 GHz memory clock speed, the core is said to be clocked about 26 MHz higher than reference. Display outputs check out as dual DVI, HDMI, and DisplayPort.
