Asus just release their "Mini-Size GPU", a GTX 670 sized (17cm) PCB, featuring a new version of DirectCU with copper base vapor-chamber inside the in the main heatsink amd appears to be a combination of an aluminum base plate covering the memory chip and VRM. The Mini DirectCU used CoolTech fan blowing wider angle airflow in multi-direction also improving more airflow and cooler than traditional fan.

"Direct Power>" This is just a copper heat sink, used to spread heat from inner PCB layer and lower down the temperature of the card.
Direct Power >> pointing at the SAP caps to maximize overclocking headroom

This card used 4+1 Power phase.
Red: 4x Hynix memory chip on the surface.
Orange: 1 phase for VRAM- video memory
Green/Blue/Purple/Pink Total 4 phase for GPU cores, 1 color is 1 phase.

This video memory used: Hynix H5GQ2H24AFA chips, a total of 8 memory chips is clocked to 6Gbps and given 2GB GDDR5

Asus used High Quality Mosfets, Two red 4937N MOSFETs act on the low-side and a single blue 4955N is used as the high-side. These MOSFETs have very low RDS(ON)
Purple: Asus used taiwan made soild caps

Overclocking & Stress test

Testing with Furmark: 100% - No Overclocking
FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that's why FurMark is also a perfect stability and stress test tool for the graphics card.

20 minutes stress test with furmark, Asus GTX 670 Mini DirectCu manage to keep the card cool with 57% fan speed and 79 degree celsius.

Tuning up the fan speed to 100% the gpu temperatures stay at 68-70 degree celsius with 20 minutes stress test.

Overclocking:

I've push the card higher clock speed 1120Mhz core clock and 6500mhz memory clock speed
