Titan Dual X Holder TTC-SC07TZ(RB) Review @ OCC
 

The fans operated perfectly, the fan holder/frame setup worked fine, and the tool-less nature was nice. But, it would have been desirable to see thumb screws for the expansion slot versus standard Phillips-head screws to finish the idea off. The Dual X Holder has great potential in the right systems. But with a reference Radeon HD 6970 and a powerful blower motor, the performance was just about the same, only having a slight decrease in temperatures while overclocked. The Holder also sagged when installed in the test rig, rather than sitting parallel to the video card.
