The cooler heatsink is topped with a pair of 70 x 70 x 10mm fans fastened with four screws in an aluminum frame:
Each of these 11-blade fans rotates at a constant speed of ~2000RPM creating a combined airflow of 31CFM and generating ~26.2dBA of noise. The TFD-7010SL12Z fans use a slide bearing with unknown MTBF:
Both fans consume maximum 2.166W of power. They have a three-pin power connector and no color highlighting.
Titan Twin Turbo is compatible with many graphics cards starting from old ATI Radeon 7000 and Nvidia GeForce 3 Ti 200 and finishing with Radeon HD 2400/2600 and GeForce 9600/9800 GT. You can download the installation instructions from the official web-site. Two retention loops have threaded holes and the other two plain holes. The distances between the opposite diagonal holes measure 54.8mm, 79.7mm, 75.4mm and 61.1mm. Depending on the graphics card you have you insert two or four retention spindles into these holes and install the cooler on to the card. After that you tighten the thumb-screws with springs at the bottom of the PCB:
Unfortunately, since Titan Twin Turbo is not officially compatible with ATI Radeon HD 3870/3850 and HD 4870/4850, you can only fasten this cooler using two screws out of four. As a result, even though the cooler base is pressed completely against the card, you can still shift it within the difference between the retention holes and spindles by applying a little effort.
This is what Titan Twin Turbo looks like installed onto ATI Radeon HD 4870:
The cooler and its heatpipes do not interfere with any components on the lower part of the graphics card PCB. However, if you decide to stick the aluminum heatsinks onto the memory chips, the heatpipes will be in the way of two middle heatsinks along the upper side of the PCB:
These were the only problems we had with Titan Twin Turbo installation. The cooler will block the slot next to the graphics card. Moreover, you should not use large expansion cards in the second slot, too, because the cooling efficiency will most likely worsen in this case.
In conclusion I would like to add that Titan Twin Turbo currently sells for ~$45.
